Interim Financial Statements

(PPL, PPL Energy Supply and PPL Electric)

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all of the information and footnotes required by accounting principles generally accepted in the U.S. for complete financial statements. In the opinion of management, all adjustments (including normal, recurring accruals) considered necessary for a fair presentation in accordance with accounting principles generally accepted in the U.S. are reflected in the condensed consolidated financial statements. The Balance SheetSheets as of December 31, 2005, is2006, are derived from each Registrant's 20052006 audited Balance Sheet. The financial statements and notes thereto should be read in conjunction with the financial statements and notes contained in each Registrant's 20052006 Form 10-K. The results of operations for the three months ended March 31, 2006,2007, are not necessarily indicative of the results to be expected for the full year ending December 31, 2006,2007, or other future periods, because results for interim periods can be disproportionately influenced by various factors and developments and seasonal variations.

(PPL and PPL Electric)

The three months ended March 31, 2005, included costs in "Other Operation and Maintenance" on the Statement of Income of $16 million associated with severe ice storms that hit PPL Electric's service territory in January 2005. In August 2005, the PUC issued an order granting PPL Electric's petition for authority to defer and amortize for regulatory accounting and reporting purposes a portion of these storm costs subject to certain conditions. As a result of the PUC Order and in accordance with SFAS 71, "Accounting for the Effects of Certain Types of Regulation," in the third quarter of 2005, PPL Electric deferred $12 million of its previously expensed storm costs.

Summary of Significant Accounting Policies

(PPL, PPL Energy Supply and PPL Electric)

The following accounting policy disclosures represent updates to the "Summary of Significant Accounting Policies" Note in each Registrant's 20052006 Form 10-K.

Allowance for Doubtful Accounts Income Taxes(PPL and PPL Energy Supply)

PPL'sPrior to January 1, 2007, and in accordance with SFAS 5 "Accounting for Contingencies," PPL Energy Supply's significant specific reserves relate to receivables from Enron Corporation (Enron), which filedand its subsidiaries evaluated uncertain tax positions and accrued charges for bankruptcyprobable exposures based on management's best estimate of the amount of benefit that should be recognized in 2001, and from the California ISO, which has withheld payment pending the outcome of regulatory proceedings arising from the California electricity supply situation that began in 2000.financial statements.

The reserves related to Enron are claims against Enron North America and Enron Power Marketing (Enron Subsidiaries), and against Enron, which had guaranteed the Enron Subsidiaries' performance (Enron Corporation Guarantees).

In MarchJune 2006, the U.S. Bankruptcy Court approved agreements between Enron and PPL subsidiaries that settledFASB issued FIN 48, "Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109." In May 2007, the litigation betweenFASB amended this guidance by issuing FSP FIN 48-1, "Definition of Settlement in FASB Interpretation No. 48." PPL and Enron regardingits subsidiaries adopted FIN 48, as amended, effective January 1, 2007. The adoption resulted in the validityrecognition of a cumulative effect adjustment to the opening balance of retained earnings for that fiscal year. Effective with the adoption, uncertain tax positions are no longer considered to be contingencies assessed in accordance with SFAS 5. FIN 48 requires an entity to evaluate its tax positions following a two-step process. The first step requires an entity to determine whether, based on the technical merits supporting a particular tax position, it is more likely than not (greater than a 50 percent chance) that the tax position will be sustained. This determination assumes that the relevant taxing authority will examine the tax position and enforceabilityis aware of all the relevant facts surrounding the tax position. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The measurement of the Enron Corporation Guarantees. Asbenefit equals the largest amount of benefit that has a resultlikelihood of realization, upon settlement, that exceeds 50 percent. If the Bankruptcy Court's approval ofmore-likely-than-not threshold is not met, it is inappropriate to recognize any tax benefits associated with the settlement of the Enron Corporation Guarantees litigation and an assessment of current price quotestax position. See Note 5 for the purchaseimpact of Enron claims, PPL reducedadopting FIN 48 as well as the associated allowance for doubtful accounts by $15 million, or $9 million after tax ($0.03 per share for PPL).required disclosures.

At March 31, 2006 and December 31, 2005, the Enron and California ISO reserves accounted for 51% and 60% of PPL's total allowance for doubtful accounts and 76% and 80% of PPL Energy Supply's total allowance for doubtful accounts.

Earnings Per Share

(PPL)

In August 2005, PPL completed a 2-for-1 split of its common stock. The record date for the stock split was August 17, 2005, and the distribution date was August 24, 2005. As a result of the stock split, 190 million shares were issued to shareholders, and 31 million shares were issued as treasury shares as of the record date. The par value of the stock remains at $0.01 per share and, accordingly, $2 million was transferred from "Capital in excess of par value" to "Common stock" on the Balance Sheet. The number of shares, the market price, and earnings and dividends per share amounts, as well as PPL's stock-based compensation awards and the conversion rate and market price trigger of PPL Energy Supply's 2.625% Convertible Senior Notes due 2023, in the financial statements for the period ended March 31, 2005, have been adjusted to reflect the stock split.

Basic EPS is calculated using the weighted-average number of common shares outstanding during the period. Diluted EPS is calculated using the weighted-average shares of common stock outstanding that are increased for additional shares that would be outstanding if potentially dilutive securities were converted to common stock. Potentially dilutive securities consist of:

·stock options, restricted stock and restricted stock units granted under the incentive compensation plans;
·stock units representing common stock granted under the directors compensation programs; and
·convertible senior notes.

The basic and diluted EPS calculations, and the reconciliation of the shares (in thousands) used in the calculations, are:

If converted, PPL Energy Supply's $400 million 2.625% Convertible Senior Notes due 2023 require cash settlement of the principal amount and permit settlement of any conversion premium in cash or PPL common stock. Based upon the current conversion rate of 40.2212 shares per $1,000 principal amount of notes (or $24.8625 per share), the Convertible Senior Notes have a dilutive impact when the average market price of PPL common stock equals or exceeds the conversion price of $24.87.

See Note 7 for discussion of attainment of the market price trigger related to the Convertible Senior Notes in the first quarter of 2006.2007.

As of March 31, 2007, $102 million of Convertible Senior Notes remained outstanding. The maximum number of shares of PPL common stock that could potentially be issued to settle the conversion premium, based upon the current conversion rate, is 16,088,4804,113,301 shares. Based on PPL's common stock price at March 31, 2006,2007, the conversion premium equated to 2,483,0381,612,886 shares, or $73$66 million.

During the three months ended March 31, 2007, PPL issued 330,311 shares of common stock related to the exercise of stock options and vesting of restricted stock units under its stock-based compensation plans.

The following number of stock options to purchase PPL common shares were excluded in the respective periods' computations of diluted EPS because the effect would have been antidilutive.

Unrecognized Tax Benefits

(PPL, PPL Energy Supply and PPL Electric)

In June 2006, the FASB issued FIN 48, "Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109." In May 2007, the FASB amended this guidance by issuing FSP FIN 48-1, "Definition of Settlement in FASB Interpretation No. 48." PPL and its subsidiaries adopted FIN 48, as amended, effective January 1, 2007. The adoption resulted in the following increases (decreases) to the Balance Sheet.

At January 1, 2007 the total unrecognized tax benefits and related indirect effects that if recognized would decrease the effective tax rate were:

Total indirect effect of unrecognized tax benefits on other tax jurisdictions  (43)  (12)  (31)
Total unrecognized tax benefits and related indirect effects that if recognized would decrease the effective tax rate $163  $121  $37 

It is reasonably possible that during the next 12 months the total amount of unrecognized tax benefits, recorded at January 1, 2007, could decrease between $25 million and $106 million for PPL, decrease between $30 million and $91 million for PPL Energy Supply and decrease by up to $9 million for PPL Electric, as a result of subsequent recognition, derecognition and/or changes in measurement of uncertain tax positions related to the creditability of foreign taxes, the timing and utilization of foreign tax credits and the related impact on alternative minimum tax and other credits, the timing and/or valuation of certain deductions, intercompany transactions and unitary filing groups. The events that could cause these changes are direct settlements with taxing authorities, litigation, legal or administrative guidance by relevant taxing authorities and the lapse of an applicable statute of limitation. During the three months ended March 31, 2007, there were no significant changes to PPL and its subsidiaries' unrecognized tax benefits.

Consistent with prior periods, it is PPL and its subsidiaries' policy to record interest and penalties in "Income Taxes" on their Statements of Income.

At January 1, 2007, interest and penalties accrued on the Balance Sheet were:

  
PPL
 
PPL Energy Supply
 
PPL Electric
             
Accrued interest $37  $29  $8 
Accrued penalties  1   1     
Total accrued interest and penalties $38  $30  $8 

PPL or its subsidiaries file tax returns in five major tax jurisdictions. PPL Energy Supply's and PPL Electric's U.S. federal and state tax provision are calculated in accordance with an intercompany tax sharing policy with PPL which provides that their taxable income be calculated as if PPL Energy Supply and its domestic subsidiaries and PPL Electric and its subsidiaries each filed a separate consolidated tax return. Based on this tax sharing policy, PPL Energy Supply or its subsidiaries indirectly or directly file tax returns in five major tax jurisdictions and PPL Electric or its subsidiaries indirectly or directly file tax returns in two major tax jurisdictions. These jurisdictions, as well as the tax years that are no longer subject to examination, are as follows:

(PPL and PPL Energy Supply)

At March 31, 2007, as a result of PPL's plan to dispose of its Latin American businesses, PPL and PPL Energy Supply classified $4 million of unrecognized tax benefits in "Liabilities held for sale and related minority interests," a current liability on the Balance Sheet. If these unrecognized tax benefits were subsequently recognized, they would not impact PPL's and PPL Energy Supply's effective tax rate.

Credit Arrangements and Financing Activities

Credit Arrangements

(PPL and PPL Electric)

PPL Electric maintains credit facilities in order to enhance liquidity and provide credit support, and as a backstop to its commercial paper program. At March 31, 2006, no cash borrowings were outstanding under any PPL Electric credit facilities.

PPL Electric maintains two credit facilities: a $200 million five-year facility maturing in June 2010 and a $100 million three-year facility maturing in June 2006. PPL Electric has the ability to cause the lenders under its facilities to issue letters of credit. At March 31, 2006, PPL Electric had less than $1 million of letters of credit outstanding under its credit facilities.

PPL Electric maintains a commercial paper program for up to $200 million to provide it with an additional financing source to fund its short-term liquidity needs, if and when necessary. Commercial paper issuances are supported by certain credit agreements of PPL Electric. PPL Electric had $100 million of commercial paper outstanding at March 31, 2006, with a weighted-average interest rate of 4.83%.

At March 31, 2006, $155 million of accounts receivable and $129 million of unbilled revenue were pledged by a PPL Electric subsidiary under the credit agreement related to PPL Electric's and the subsidiary's participation in an asset-backed commercial paper program. Also at this date, there was $42 million of short-term debt outstanding under the credit agreement at an interest rate of 4.70%, all of which was being used to cash collateralize letters of credit issued on PPL Electric's behalf. At March 31, 2006, based on the accounts receivable and unbilled revenue pledged, an additional $108 million was available for borrowing. PPL Electric's sale to its subsidiary of the pledged accounts receivable and unbilled revenue is an absolute sale of the assets, and PPL Electric does not retain an interest in these assets. However, for financial reporting purposes, the subsidiary's financial results are consolidated in PPL Electric's financial statements.

Due to a combination of significant capital requirements for the transport operations and competing capital needs in PPL's core electricity supply and delivery businesses, PPL has decided to actively market these transport operations, and believes a sale is probable within one year.

In the first quarter of 2007, PPL and PPL Energy Supply recorded a $31 million pre-tax ($18 million after tax) write-down in the carrying value of the transport assets to their estimated fair value. This impairment charge is included in "Energy-related businesses" expenses on the Statement of Income.

PPL uses historical volatility to value its stock options using the Black-Scholes option pricing model. Volatility over the expected term of the options is evaluated with consideration given to prior periods that may need to be excluded based on events not likely to recur that had impacted PPL's volatility in those prior periods. Management's expectations for future volatility, considering potential changes to PPL's business model and other economic conditions, are also reviewed in addition to the historical data to determine the final volatility assumption.

Directors Stock Units(PPL)

Under the Directors Deferred Compensation Plan, stock units are used to compensate members of PPL's Board of Directors who are not employees of PPL. Such stock units represent shares of PPL's common stock to which board members are entitled after they cease serving as a member of the Board of Directors. Board members are also entitled to defer any or all of their cash compensation into stock units. The stock unit accounts of each board member are increased based on dividends paid or other distributions on PPL's common stock. There were 282,008 stock units outstandingliabilities at March 31, 2006.

Energy Purchase Commitments(PPL and PPL Energy Supply and PPL Electric)Supply)

PPL and PPL Energy Supply enter into long-term purchase contracts to supply the fuel requirements for generation facilities. These include contracts to purchase coal, emission allowances, natural gas, oil and nuclear fuel. These contracts extend for terms through 2019. PPL and PPL Energy Supply also enter into long-term contracts for the storage and transporttransportation of natural gas. These contracts extend through 2014 and 2032, respectively.2032. Additionally, PPL and PPL Energy Supply enterhave entered into long-term contracts to purchase power that extend for terms through 2010.

PPL and PPL Energy Supply entered into2017, excluding long-term power purchase agreements with two wind project developers to purchase thefor full output of their facilities when they begin commercial operation. One of the power purchase agreements istwo windfarms. These windfarm contracts extend for 50-100 MW and extends for a term of 15 years. The in-service date for this project is under evaluation. The other power purchase agreement is for 24 MW and extends for a termterms through 2026.

As part of the purchase of generation assets from Montana Power, PPL Montana assumed a power purchase agreement, which was still in effect at March 31, 2006. In accordance with purchase accounting guidelines, PPL Montana recorded a liability of $58 million as the estimated fair value of the agreement at the acquisition date. The liability is being reduced over the term of the agreement, through 2010, as an adjustment to "Energy purchases" on the Statement of Income. The unamortized balance of the liability related to the agreement at March 31, 2006, was $45 million and is included in "Deferred Credits and Other Noncurrent Liabilities - Other" on the Balance Sheet.2027.

In 1998,March 2007, PPL Electric recordedMontana entered into a loss accruallong-term coal purchase and supply agreement, which commences in 2010, for above-market contracts with NUGs of $854 million, dueColstrip Units 1 and 2. The contract is expected to the deregulation of its generation business. Effective January 1999, PPL Electric began reducing this liability as an offset to "Energy purchases" on the Statement of Income. This reduction is based on the estimated timing of the purchases from the NUGs and projected market prices for this generation. The final NUG contract expires in 2014. In connection with the corporate realignment in 2000, the remaining balance of this liability was transferred to PPL EnergyPlus. At March 31, 2006, the remaining liability associated with the above-market NUG contracts was $188 million.extend through 2019.

Energy Sales Commitments (PPL and PPL Energy Supply)

PPL Energy Supply entershad entered into long-term power sales contracts in connection with its load-servingmarketing activities or associated with certain of its power plants. These power sales contracts extend for terms through 2017. All long-term contracts were executed at pricing that approximated market rates, including profit margin, at the time of execution.

On July 1, 2002,In 2007, PPL Montana began to sell to NorthWestern an aggregate of 450 MW of energy. Under two five-year agreements,Energy Supply has entered into full requirements contracts with various counterparties. These contracts commence in mid-2007, and the longest contracts extend through 2010. PPL Montana is supplying 300 MW of around-the-clock electricity and 150 MW of unit-contingent on-peak electricity. PPL Montana also makes short-term energy sales to NorthWestern.

In 2002, PPL began commercial operations of its Edgewood natural gas-fired generating station and its Shoreham oil-fired generating station. Each of these New York plants has a capacity of 79.9 MW. Initially, the Long Island Power Authority contracted to purchase all of Edgewood's capacity and ancillary services as part of a 3-year power purchase agreement with PPL EnergyPlus beginning at commercial operation, and all of Shoreham's capacity and ancillary services as part of a 15-year power purchase agreement with PPL EnergyPlus beginning at commercial operation. In 2005, PPL EnergyPlus extended the Edgewood power purchase agreement for an additional term that runs through October 2008. The Shoreham power purchase agreement remains in effect until 2017.

In January 2004, PPL EnergyPlus began supplying 12.5% of Connecticut Light & Power Company's (CL&P) Transitional Standard Offer load under a three-year fixed-price contract. During peak hours, PPL EnergyPlus'Energy Supply's obligation to supply the Transitional Standard Offer load may reach 625 MW. Additionally, in January 2006, PPL EnergyPlus began to supply an additional 6.25% of CL&P's Transitional Standard Offer load under a one-year fixed-price contract. During peak hours, PPL EnergyPlus' obligationthese contracts is expected to supply the Transitional Standard Offer load may reach 313approximately 1,340 MW.

As a result of New Jersey's Electric Discount andUnder these contracts, if PPL Energy Competition Act,Supply's credit rating falls below investment grade or PPL Energy Supply's contract exposure exceeds the New Jersey Board of Public Utilities authorized and made availableestablished credit limit for the contract, then the counterparty has the right to power suppliers, on a competitive basis, the opportunity to provide Basic Generation Service (BGS) to all non-shopping New Jersey customers. In February 2003,request collateral from PPL EnergyPlus was awarded 34-month fixed-price BGS contracts for a fixed percentage of customer load (an aggregate of 1,000 MW) for Atlantic City Electric Company (ACE), Jersey Central Power & Light Company (JCPL) and Public Service Electric & Gas Company (PSEG). These contracts commenced in August 2003. In the first quarter of 2005, PPL EnergyPlus was awarded a portion of the Commercial Industrial Energy Pricing tranche, which amounts to 85 MW after expected shopping. These 12-month contracts began in June 2005. In February 2006, PPL EnergyPlus was awarded 36-month fixed-price BGS contracts for fixed percentages of customer load (an aggregate of 600 MW) for ACE, JCPL and PSEG. These contracts commence in June 2006.

In December 2005 and January 2006, PPL EnergyPlus entered into agreements with Delmarva Power and Light Company to provide a portion of its full requirements service from May 2006 through May 2008.Supply.

PPL Montana Hydroelectric License Commitments (PPL and PPL Energy Supply)

PPL Montana has 11 hydroelectric facilities and one storage reservoir licensed by the FERC pursuant to the Federal Power Act under long-term licenses. Pursuant to Section 8(e) of the Federal Power Act, the FERC approved the transfer from Montana Power to PPL Montana of all pertinent licenses and any amendments in connection with the Montana APA.Asset Purchase Agreement.

The Kerr Dam Project license was jointly issued by the FERC to Montana Power and the Confederated Salish and Kootenai Tribes of the Flathead Reservation in 1985, and required Montana Power to hold and operate the project for 30 years. The license required Montana Power, and subsequently PPL Montana as a result of the purchase of the Kerr Dam from Montana Power, to continue to implement a plan to mitigate the impact of the Kerr Dam on fish, wildlife and the habitat. Under this arrangement, PPL Montana has a remaining commitment to spend $19$18 million between 20062007 and 2015, at which pointin addition to the annual rental it pays to the tribes. Between 2015 and 2025, the tribes have the option to purchase, hold and operate the project.project for the remainder of the license term of 2035.

PPL Montana entered into two Memoranda of Understanding (MOUs) with state, federal and private entities related to the issuance in 2000 of the FERC renewal license for the nine dams for the Missouri-Madison project. The MOUs require PPL Montana to implement plans to mitigate the impact of its projects on fish, wildlife and the habitat, and to increase recreational opportunities. The MOUs were created to maximize collaboration between the parties and enhance the possibility for matching funds from relevant federal agencies. Under this arrangement, PPL Montana has a remaining commitment to spend $34$30 million between 20062007 and 2040.

Settlement of Enron Receivables (PPL and PPL Energy Supply)

PPL and PPL Energy Supply had significant specific reserves related to receivables from Enron Corporation (Enron), which filed for bankruptcy in 2001. The reserves related to Enron were for claims against Enron North America and Enron Power Marketing (Enron Subsidiaries), and against Enron, which had guaranteed the Enron Subsidiaries' performance (Enron Corporation Guarantees).

In March 2006, the U.S. Bankruptcy Court approved agreements between Enron and PPL Energy Supply that settled the litigation between PPL Energy Supply and Enron regarding the validity and enforceability of the Enron Corporation Guarantees. As a result of the Bankruptcy Court's approval of the settlement of the Enron Corporation Guarantees litigation and an assessment of current market price quotes for the purchase of Enron claims, PPL Energy Supply reduced the associated allowance for doubtful accounts for the three months ended March 31, 2006, by $15 million or $9 million after tax.

Legal Matters

(PPL, PPL Energy Supply and PPL Electric)

PPL and its subsidiaries are involved in numerous legal proceedings, claims and litigation in the ordinary course of business. PPL and its subsidiaries cannot predict the outcome of such matters, or whether such matters may result in material liabilities.

Montana Power Shareholders' Litigation (PPL and PPL Energy Supply)

In August 2001, a purported class-action lawsuit was filed by a group of shareholders of Montana Power against Montana Power, the directors of Montana Power, certain advisors and consultants of Montana Power, and PPL Montana. The plaintiffs allege, among other things, that Montana Power was required to, and did not, obtain shareholder approval of the sale of Montana Power's generation assets to PPL Montana in 1999, and thus that sale "was null and void ab initio." Among the remedies that the plaintiffs are seeking is the establishment of a "resulting and/or constructive trust" on both the generation assets and all profits earned by PPL Montana from the generation assets, plus interest on the amounts subject to the trust. This lawsuit has been pending in the U.S. District Court of Montana, Butte Division, and the judge has placed this proceeding on hold pending the outcome of certain motions currently before the U.S. Bankruptcy Court for the District of Delaware, the resolution of which may impact this proceeding. Recently, the judge in this case has indicated that he plans to hold a status conference for the purpose of resuming proceedings. PPL and PPL Energy Supply cannot predict the outcome of this matter.

Montana Hydroelectric Litigation (PPL and PPL Energy Supply)

In November 2004, PPL Montana, Avista Corporation and PacifiCorp commenced an action for declaratory judgment in Montana First Judicial District Court seeking a determination that no lease payments or other compensation for their hydropower facilities' use and occupancy of streambeds in Montana can be collected by the State of Montana. This request for declaratory judgment from the Montana state court was brought following the dismissal of the State of Montana's federal lawsuit seeking such payments or compensation in the U.S. District Court of Montana, Missoula Division, due to lack of diversity jurisdiction, seeking such payments or compensation.jurisdiction. The State's federal lawsuit was founded on allegations that the bed of Montana's navigable rivers became state-owned property upon Montana's admission to statehood, and that the use of them for placement of dam structures, affiliated structures and reservoirs should, under an existing regulatory scheme, trigger lease payments for use of land underneath. In July 2006, the Montana state court approved a stipulation by the State of Montana that it is not seeking any lease payments or other compensation from PPL Montana for the period prior to PPL Montana's acquisition of the hydropower facilities in December 1999. The trial for this state court proceeding has been scheduled to commence in October 2007. PPL and PPL Energy Supply cannot predict the outcome of this state court proceeding.matter.

Regulatory Issues

California ISO and Western Markets (PPL and PPL Energy Supply)

Through its subsidiaries, PPL made $18 million of sales to the California ISO during the period from October 2000 through June 2001, of which $17 million has not been paid to PPL subsidiaries. Given the myriad of electricity supply problems presently faced by the California electric utilities and the California ISO, PPL cannot predict whether or when it will receive payment. At March 31, 2006,2007, PPL has fully reserved for possible underrecoveries of payments for these sales.

Regulatory proceedings arising out of the California electricity supply situation have been filed at the FERC. The FERC has determined that all sellers of energy into markets operated by the California ISO and the California Power Exchange, including PPL Montana, should be subject to refund liability for the period beginning October 2, 2000 through June 20, 2001, but the FERC has not yet ruled on the exact amounts that the sellers, including PPL Montana, would be required to refund. In decisions in September 2004 and August 2006, the U.S. Court of Appeals for the Ninth Circuit held that the FERC had the additional legal authority to order refunds for periods prior to October 2, 2000, and ordered the FERC to determine whether or not it would be appropriate to grant such additional refunds. As part of its August 2006 decision, the Court stayed the time to petition for rehearing of the decision and its mandate to the FERC in order to allow the parties time to conduct settlement discussions.

In June 2003, the FERC took several actions as a result of a number of related investigations. The FERC terminated proceedings pursuant to which it had been consideringconsider whether to order refunds for spot market bilateral sales made in the Pacific Northwest, including sales made by PPL Montana, during the period December 2000 through June 2001. The FERC also commenced additional investigations relating to "gaming" and bidding practices during 2000 and 2001, but, to their knowledge, neither PPL EnergyPlus nor PPL Montana is a subject of these investigations.

Litigation arising out of the California electricity supply situation has been filed in California courts against sellers of energy to the California ISO. The plaintiffs and intervenors in these legal proceedings allege, among other things, abuse of market power, manipulation of market prices, unfair trade practices and violations of state antitrust laws, and seek other relief, including treble damages and attorneys' fees. While PPL's subsidiaries have not been named by the plaintiffs in these legal proceedings, one defendant in a consolidated court proceeding named PPL Montana in its cross-complaint; this defendant denied any unlawful conduct but asserted that, if it is found liable, the other generators and power marketers, including PPL Montana, caused, contributed to and/or participated in the plaintiffs' alleged losses. In July 2006, the Court dismissed this case as the result of a settlement under which PPL Montana was not required to make any payments or provide any compensation.

In February 2004, the Montana Public Service Commission (PSC) initiated a limited investigation of the Montana retail electricity market for the years 2000 and 2001, focusing on how that market was affected by transactions involving the possible manipulation of the electricity grid in the western U.S. The investigation includes all public utilities and licensed electricity suppliers in Montana, including PPL Montana, as well as other entities that may possess relevant information. In June 2004, the Montana Attorney General served PPL Montana and more than 20 other companies with subpoenas requesting documents, and PPL Montana has provided responsive documents to the Montana Attorney General.

While PPL and its subsidiaries believe that they have not engaged in any improper trading or marketing practices affecting the California and western markets, PPL cannot predict the outcome of the above-described investigations, lawsuits and proceedings or whether any PPL subsidiaries will be the target of any additional governmental investigations or named in other lawsuits or refund proceedings.

PJM Capacity Litigation (PPL, PPL Energy Supply and PPL Electric)

In December 2002, PPL was served with a complaint against PPL, PPL EnergyPlus and PPL Electric filed in the U.S. District Court for the Eastern District of Pennsylvania by a group of 14 Pennsylvania boroughs that apparently alleged, among other things, violations of the federal antitrust laws in connection with the pricing of installed capacity in the PJM daily market during the first quarter of 2001 and certain breach of contract claims. These boroughs were wholesale customers of PPL Electric. In April 2006, the courtCourt dismissed all of the federal antitrust claims and all of the breach of contract claims except for one breach of contract claim by one of the boroughs. PPL cannot predict the outcome related to the remaining open claim.

Each of the U.S. Department of Justice - Antitrust Division, the FERC and the Pennsylvania Attorney General conducted investigations regarding PPL's PJM capacity market transactions in early 2001 and did not find any reason to take action against PPL.

New England Investigation (PPL and PPL Energy Supply)

In January 2004, PPL became aware of an investigation by the Connecticut Attorney General and the FERC's Office of Market Oversight and Investigation (OMOI) regarding allegations that natural gas-fired generators located in New England illegally sold natural gas instead of generating electricity during the week of January 12, 2004. PPL has responded to a data request of OMOI that indicated that PPL was not under suspicion of a regulatory violation, but that OMOI was conducting an initial investigation. PPL also has responded to data requests of ISO New England and data requests served by subpoena from the Connecticut Attorney General. Both OMOI and ISO New England have issued preliminary reports finding no regulatory or other violations concerning these matters. While PPL does not believe that it committed any regulatory or other violations concerning the subject matter of these investigations, PPL cannot predict the outcome of these investigations.

PJM Billing (PPL, PPL Energy Supply and PPL Electric)

In December 2004, Exelon Corporation, on behalf of its subsidiary, PECO Energy, Inc. (PECO), filed a complaint against PJM and PPL Electric with the FERC alleging that PJM had overcharged PECO from April 1998 through May 2003 as a result of an error by PJM in the State Estimator Model used in connection with billing all PJM customers for certain transmission, spot market energy and ancillary services charges. Specifically, the complaint alleged that PJM mistakenly identified PPL Electric's Elroy substation transformer as belonging to PECO and that, as a consequence, during times of congestion, PECO's bills for transmission congestion from PJM erroneously reflected energy that PPL Electric took from the Elroy substation and used to serve PPL Electric's load. The complaint requested the FERC, among other things, to direct PPL Electric to refund to PJM $39 million, plus interest of $8 million, and for PJM to refund these same amounts to PECO. In February 2005, PPL Electric filed its response with the FERC stating that neither PPL Electric nor any of its affiliates should be held financially responsible or liable to PJM or PECO as a result of PJM's error.

In April 2005, the FERC determined that PECO iswas entitled to reimbursement for the transmission congestion charges that PECO asserts PJM erroneously billed to it at the Elroy substation. The FERC set for additional proceedings before a judge the determination of the amount of the overcharge to PECO and which PJM market participants were undercharged and therefore are responsible for reimbursement to PECO.

PPL Electric recognized an after-tax charge of $27 million (or $0.07 per share for PPL) in the first quarter of 2005 for a loss contingency related to this matter. The pre-tax accrual was $47 million, with $39 million included in "Energy purchases" on the Statement of Income, and $8 million in "Interest Expense."

In September 2005, PPL Electric and Exelon Corporation filed a proposed settlement agreement regarding this matter with the FERC. In March 2006, the FERC rejected the settlement agreement indicating that the agreement involves material issues of fact that it cannot decide without further information, and ordered the matter to be set for hearing.

Subsequently, in March 2006, PPL Electric and Exelon filed with the FERC a new proposed settlement agreement under which PPL Electric would payhave paid approximately $41 million over a five-year period to PJM through a new transmission charge that, under applicable law, would be recoverable from PPL Electric's retail customers.charge. Pursuant to this proposed agreement, PJM would forwardhave forwarded the amounts collected under this new charge to PECO.

In November 2006, the FERC entered an order accepting the parties' March 2006 proposed settlement agreement, upon the condition that PPL Electric agree to certain modifications. The FERC's acceptance was conditioned upon reimbursement to PECO through a single credit to PECO's monthly PJM bill and a corresponding charge on PPL Electric's monthly PJM bill, rather than through a PJM Tariff transmission charge applicable only to PPL Electric. The FERC has not yet acted on this newordered PPL Electric to advise the FERC within 30 days as to whether it would accept or reject the proposed settlement agreement.modifications.

PPL,In December 2006, PPL Electric and Exelon filed with the FERC, pursuant to the November 2006 order, a modified offer of settlement ("Compliance Filing"). Under the Compliance Filing, PPL Energy Supply cannot be certainElectric would make a single payment through its monthly PJM bill of $38 million, plus interest through the date of payment, and PJM would include a single credit for this amount in PECO's monthly PJM bill. Through December 31, 2006, the estimated interest on this payment was $4 million, for a total PPL Electric payment of $42 million.

Some or all of the first quarter 2005 charges for this matter may be reversed in a future period depending on the outcome of this matter, the potential for recovery of any amounts paid as a result of the additional FERC proceedings, the application of the relevant provisions of the energypower supply agreements between PPL Electric and PPL EnergyPlus, PPL determined that PPL Electric was responsible for the claims prior to July 1, 2000 (totaling $12 million), and other factors. Dependingthat PPL EnergyPlus was responsible for the claims subsequent to that date (totaling $30 million).

Based on these factors, the Compliance Filing, PPL and PPL Electric reduced the recorded loss accrual by $5 million at December 31, 2006. PPL Electric also recorded a receivable from PPL EnergyPlus of $30 million at December 31, 2006, for the portion of the claims allocated to PPL EnergyPlus. As a result of the reduction of the loss accrual and the allocation to PPL EnergyPlus, PPL Electric recorded credits to expense of $35 million on the Statement of Income, including $28 million of "Energy purchases" and $7 million of "Interest Expense."

PPL Energy Supply recorded a loss accrual of $30 million at December 31, 2006, for its share of the parent company ofclaims, and recorded a corresponding payable to PPL Electric.

In March 2007, the FERC entered an order approving the Compliance Filing. In April 2007, PPL Electric paid PJM the full settlement amount of $43 million, including additional interest of $1 million recorded during the three months ended March 31, 2007. This proceeding is now terminated.

FERC Market-Based Rate Authority (PPL and PPL Energy Supply)

In December 1998, the FERC issued an order authorizing PPL EnergyPlus to make wholesale sales of electric power and related products at market-based rates. In that order, the FERC directed PPL EnergyPlus to file an updated market analysis within three years of the date of the order, and every three years thereafter. The most recent market-based rate filings with the FERC were made in November 2004 by PPL EnergyPlus, PPL Electric, PPL Montana and most of PPL Generation's subsidiaries. These filings consisted of a Western market-based rate filing for PPL Montana and an Eastern market-based rate filing for most of the other PPL subsidiaries in the PJM region.

In September 2005, the FERC issued an order conditionally approving the Eastern market-based rate filing, subject to PPL subsidiaries making a compliance filing providing further support that they cannot erect other non-transmission barriers to entry into the generation market. The PPL subsidiaries made this compliance filing in October 2005.2005, which the FERC accepted.

Also in September 2005, inIn May 2006, the FERC issued an order onrejecting the claims of the various parties in the proceeding regarding PPL's westernWestern market-based rate filing the FERC found that PPL Montana did not pass one of the FERC's initial screening tests for market power in NorthWestern's control area, namely the wholesale market share screen. As a result, PPL Montana was required to make a more detailed filing with the FERC demonstrating that it meets the market power tests. Also, the FERC has established a refund effective date of November 8, 2005 (for sales made in NorthWestern's control area pursuant to contracts entered into on and after that date), in the event that PPL Montana does not pass the FERC's market power tests. The FERC's order is not a definitive determination that PPL Montana has market power but rather the FERC's mechanism for analyzing market-based rate authority applications that require further scrutiny. In October 2005, PPL Montana made the more detailed filing with the FERC, which PPL Montana believes demonstrates that it cannot exercise generation market power in NorthWestern's control area and should be granted market-based rate authority in that area. The Montana Public Service Commission is contending in this proceeding that PPL Montana possesses market power in NorthWestern's control area and that the FERC should deny PPL Montana authority to sell power at market-based rates. The Montana Consumer Counsel is contending in this proceeding that PPL Montana has market power in NorthWestern's control area, that the FERC should deny PPL Montana authority to sell power in NorthWestern's control area at market-based rates and that PPL Montana cannot legally refuse to sell power to NorthWestern at cost-based rates if the FERC deniesgranting PPL Montana market-based rate authority in NorthWestern's control area. TheThere are two outstanding requests for rehearing of the FERC's order, and the FERC has not yet acted on PPL Montana'sissued a routine order allowing more detailed filing.time to consider these rehearing requests. While PPL Montana continues to believe that it does not have market power in NorthWestern's control area and that it has no obligations to make additional sales of power to NorthWestern regardless of the outcome of this proceeding, it cannot predict the outcome of these proceedings.

Currently, if a seller is granted market-based rate authority by the FERC, it may enter into power contracts during the time period for which such authority has been granted. If the FERC determines that the market is not workably competitive or the seller possesses market power or is not charging just and reasonable rates, the FERC institutes prospective action. Any contracts entered into pursuant to the FERC's market-based rate authority remain in effect and are generally subject to a high standard of review before the FERC can order any changes. Recent court decisions by the U.S. Court of Appeals for the Ninth Circuit have raised issues that may make it more difficult for the FERC to continue its program of promoting wholesale electricity competition through market-based rate authority. These court decisions permit retroactive refunds and a lower standard of review by the FERC for changing power contracts, and could have the effect of requiring the FERC to review in advance most, if not all, power contracts. The FERC has not yet taken action in response to these recent court decisions, and the decisions have been or are expected to be appealed to the U.S. Supreme Court. At this proceeding.
time, PPL cannot predict the impact of these court decisions on the FERC's future market-based rate authority program or on PPL's business.

Illinois Auction Complaints(PPL and PPL Energy Supply)

As a result of the Electric Service Customer Choice and Rate Relief Law of 1997, the Illinois General Assembly provided the opportunity for power suppliers to compete to supply power to Illinois electric utilities to meet the full requirements of all non-shopping Illinois electricity customers. The Illinois Commerce Commission (ICC) conducted an auction for supply of up to 25,474 MW of peak load and hired an independent Auction Monitor for this purpose. PPL EnergyPlus submitted bids in this Illinois auction process and, as a result, in September 2006 entered into three agreements with Commonwealth Edison Company to supply a portion of its full requirements service. These agreements commenced in January 2007 and expire after 17, 29 and 41 months. During peak hours, PPL EnergyPlus' obligation to supply Commonwealth Edison may reach 700 MW. At the conclusion of the auction process, the Auction Monitor and the ICC Staff both concluded that the auction process was competitive.

In March 2007, the Illinois Attorney General filed a complaint at the FERC against all of the successful bidders in this auction process, including PPL EnergyPlus and fifteen other suppliers, alleging market manipulation and requesting that the FERC investigate such allegations, requesting refunds for sales at prices above just and reasonable rates and seeking revocation of the FERC market-based rate authority for certain of the suppliers. The redacted copy of the complaint served on PPL EnergyPlus does not identify which suppliers allegedly engaged in market manipulation or which suppliers allegedly should have their market-based rate authority revoked.

PPL EnergyPlus is reviewing the complaint and gathering information regarding the allegations. Subsequent to the Illinois Attorney General's complaint, two class actions were filed in Illinois State Court in Cook County against all successful bidders in the Illinois auction, including PPL EnergyPlus, alleging violations of unfair trade practices laws. The factual allegations appear similar to those in the Attorney General's complaint. While PPL and PPL Energy Supply do not currently believe that these matters will have a material adverse impact on the financial condition of PPL and PPL Energy Supply, they cannot predict the outcome of this matter.

Wallingford Cost-Based Rates (PPL and PPL Energy Supply)

In January 2003, PPL negotiated an agreement with ISO New England that would declare that four of the five units at PPL's Wallingford, Connecticut facility are "reliability must run" (RMR) units and put those units under cost-based rates. This RMR agreement and the cost-based rates are subject to approval by the FERC's approval.FERC. In May 2003, the FERC denied PPL's request for approval of the RMR agreement and cost-based rates, but in August 2005, the U.S. Court of Appeals for the District of Columbia Circuit reversed the FERC's denial and remanded the case to the FERC for further consideration. In April 2006, the FERC conditionally approved the RMR agreement and the cost-based rates for the four Wallingford units, effective February 1, 2003, subject to refund, hearing and settlement procedures. The FERC ordered a hearing to determine whether the Wallingford facilityunits needed the RMR agreement, the proposed cost-based rates under the RMR agreement and the financial accountingamounts to be recovered for past periods under the RMR agreement. Any rates collected under the RMR agreement prior to the completion of the hearing and/or settlement proceedings will beare subject to refund pending the outcome of the proceedings. The hearing will behas been held in abeyance until about early June 2006, pending the outcome of the settlement proceduresproceedings among the interested parties.

In September 2006, PPL and certain of the parties filed a written settlement with the FERC. The settlement is unopposed and resolves all interested parties.issues in the pending proceeding, including payments to PPL for the past period and going forward. Under the terms of the settlement, PPL would receive a total of $44 million in settlement of amounts due under the RMR agreement for the period February 1, 2003 through May 31, 2006. This amount (plus interest) would be paid to PPL in approximately equal monthly installments over a two-year period. In addition, PPL would enter into a revised RMR Agreement effective as of June 1, 2006, under which it would be entitled to receive $2 million per month for its recovery of fixed costs while the agreement remains in effect. PPL has deferred $16 million of payments related to the pending RMR settlement as of March 31, 2007. In October 2006, the administrative law judge assigned to this matter certified the settlement to the FERC for its consideration as an uncontested settlement.

In March 2007, the FERC approved the settlement agreement, subject to the condition that the parties file revisions to provide that the FERC will be bound to the "just and reasonable" and not the "public interest" standard of review in its consideration of modifications to the agreement. In compliance with the March 2007 order, PPL and the other settling parties submitted a compliance filing to the FERC in April 2007, revising the settlement offer and the RMR agreement to accept this condition.

PPL and PPL Energy Supply currently expect that the four Wallingford RMR units will begin to participate in ISO New England's locational forward reserve market in June 2007, at which time the revised RMR Agreement would terminate in accordance with the settlement provided certain conditions are met. The ISO New England locational forward reserve market provides revenues to peaking generation units that can quickly come on line from reserve status to meet reliability requirements.

Montana Public Service Commissioner's Litigation(PPL and PPL Energy Supply)

In May 2006, one of the commissioners of the Montana PSC commenced an action in Montana First Judicial District Court against PPL Montana and the Montana PSC seeking to cause the Montana PSC to reverse its 1999 order consenting to EWG status for PPL Montana's power plants. In 1999, the FERC had granted the plants EWG status and the authority to sell electricity produced at market-based rates, and the Montana PSC consented to this status for PPL Montana's plants under a provision of federal law. In September 2006, the Court granted PPL Montana's and the Montana PSC's motions to dismiss this action. The plaintiff has appealed the dismissal of the lawsuit to the Montana Supreme Court. PPL and PPL Energy Supply continue to believe that this lawsuit is groundless and beyond the statute of limitations period, but cannot predict the outcome of this matter.

IRS Synthetic Fuels Tax Credits (PPL and PPL Energy Supply)

PPL, through its subsidiaries, has interests in two synthetic fuel production facilities: the Somerset facility located in Pennsylvania and the Tyrone facility located in Kentucky. PPL receives tax credits pursuant to Section 2929/45K of the Internal Revenue Code based on the sale of synthetic fuel from these facilities to unaffiliated third-party purchasers.facilities. Section 29 of the Internal Revenue Code provides tax credits for the production and sale of solid synthetic fuels produced from coal. Section 2929/45K tax credits are currently scheduled to expire at the end of 2007.

To qualify for the Section 2929/45K tax credits, the synthetic fuel must meet three primary conditions: (i) there must be a significant chemical change in the coal feedstock, (ii) the product must be sold to an unaffiliated entity, and (iii) the production facility must have been placed in service before July 1, 1998.

In addition, Section 2929/45K provides for the synthetic fuel tax credit to begin to phase out when the relevant annual reference price for crude oil, which is the domestic first purchase price (DFPP), falls within a designated range and to be eliminated when the DFPP exceeds the range. The phase-out range is adjusted annually for inflation. Currently, the DFPP is published by the IRS annually in April for the prior year and is calculated based on the annual average wellhead price per barrel for all unregulated domestic crude oil. At December 31, 2006, PPL experienced nohad estimated a phase-out of taxapproximately 35% of the gross-tax credits in 2005, based2006. Based on the final published DFPP reference price andfor 2006, the phase-out range applicable for 2005.percentage is now expected to be approximately 33%. A final calculation of the related 2006 tax credits net of the revised phase-out will be calculated upon receipt of all relevant tax information. PPL does not expect the actual net tax credits to be materially different than those estimated at December 31, 2006.

Accounting for inflation, PPL currently estimates the phase-out range for 20062007 to begin at $54about $57 per barrel (DFPP) and the tax credits to be totally eliminated at about $68$71 per barrel (DFPP). Due toPPL currently expects a phase-out of approximately 10% of the volatilitygross tax credits produced in 2007, based on its estimate of the DFPP reference price and the phase-out range applicable for 2007. If the price of crude oil prices,increases above current price levels in 2007, PPL's synthetic fuel tax credits for 2007 could be significantly reduced or eliminated. PPL cannot predict or estimate with any certainty the final DFPP reference price for crude oil or the phase-out range for 2006 and 2007. However, if the price of crude oil remains at, or increases above, current price levels in 2006 or 2007, under current phase-out provisions, PPL's synthetic fuel tax credits for either or both of those years would be significantly reduced or eliminated.

Since PPL began the synthetic fuel operations, the synthetic fuel produced at the Somerset and Tyrone facilities havehas resulted in an aggregate recognition of approximately $276tax credits of an estimated $305 million for Somerset and $66$105 million of tax creditsfor Tyrone as of March 31, 2006. During2007, including estimated amounts for the first quarter of 2006,2007. After considering the facilities produced $15 million and $12 millionestimated 2007 phase-out of tax credits before phase-out. As of March 31, 2006,approximately 10%, PPL currently estimates the 2006 phase-out to be approximately 44%, resulting in a recognition of $8recognized $14 million of tax credits for Somerset and $7$12 million of tax credits for Tyrone.Tyrone for the quarter ending March 31, 2007. An estimated $2 million of the gross tax credits for Somerset and $1 million for Tyrone were not recognized for the three months ended March 31, 2007, due to the phase-out range and the estimated DFPP reference price.

In 2005, PPL entered intohas economic hedge transactions for 2007 that serveare expected to mitigate somePPL's tax credit phase-out risk due to an increase of the earnings and cash flow impact of increasesDFPP reference price in crude oil prices for 2006 and 2007, with the2007. The mark-to-market value of these hedges is reflected in "Energy-related businesses" revenues on the Statement of Income. Based onSuch hedge transactions do not mitigate any ongoing operational or production risks associated with the Tyrone and Somerset facilities.

PPL performed impairment reviews of both its synthetic fuel production facilities during the second quarter of 2006. The reviews were prompted by the temporary suspension of operations at Somerset in April 2006, the uncertainty surrounding the future operations of each of the facilities and continued observed and forecasted high crude oil prices at that time. PPL determined that the net book value of the facilities exceeded the projected undiscounted cash flows. Therefore, in the second quarter of 2006, PPL recorded charges totaling $10 million ($6 million after tax) to fully impair its synfuel-related assets based on an internal model and other considerations,analysis. The impairment charges were reflected in early April 2006, PPL suspended operations at its Somerset facility. In addition, PPL currently expects to suspend operations"Energy-related businesses" expenses on the Statements of Income. The assets of the Tyrone facility in mid-2006. At this time, PPL cannot predictfacilities are a component of the extent to which the Somerset facility or the Tyrone facility will operate in 2006 or 2007, including whether such suspensions in operation will be permanent.Supply segment.

PPL also purchases synthetic fuel from unaffiliated third parties, at prices below the market price of coal, for use at its coal-fired power plants. In 2005, PPL's purchases from these third parties resulted in fuelFuel cost savings for the first quarter of approximately $242007 were $5 million. PPL estimates that, ifunless these third parties had discontinueddiscontinue their synthetic fuel operations and sales to PPL at the end of April 2006 due to the impact of projected DFPP oil prices it would incur additionalor otherwise, its purchases from these parties will result in fuel costs of $16 millioncost savings for the remainder of 2006.

There currently are legislative proposals pending in2007 of $20 million assuming full production throughout the U.S. Congress that could affect the potential phase-out of the synthetic fuel tax credits for 2006 and 2007. At this time, PPL cannot predict whether any such legislation will be enacted or the impact of any such legislation on its synthetic fuel operations or tax credits in 2006 or 2007.year.

In October 2003, it was reported that the U.S. Senate Permanent Subcommittee on Investigations, of the Committee on Governmental Affairs, had begun an investigation of the synthetic fuel industry and its producers. That investigation is ongoing. PPL cannot predict when the investigation will be completed or the potential results of the investigation.

Energy Policy Act of 2005 (PPL, PPL Energy Supply and PPL Electric)

In August 2005, President Bush signed into law the Energy Policy Act of 2005 (the "20052005 Energy Act")Act). The 2005 Energy Act is comprehensive legislation that will substantially affect the regulation of energy companies. The Act amends federal energy laws and provides the FERC with new oversight responsibilities. Among the important changes tothat have been or will be implemented as a result of this legislation are:

·The Public Utility Holding Company Act of 1935 has been repealed. PUHCA significantly restricted mergers and acquisitions in the electric utility sector.
·The FERC will appoint and oversee anhas appointed the North American Electric Reliability Council as the electric reliability organization to establish and enforce mandatory reliability rulesstandards ("Reliability Standards") regarding the bulk power system.system, and the FERC will oversee this process and independently enforce the Reliability Standards, as further described below.
·The FERC will establish incentives for transmission companies, such as performance-based rates, recovery of the costs to comply with reliability rules and accelerated depreciation for investments in transmission infrastructure.
·The Price AndersonPrice-Anderson Amendments Act of 1988, which provides the framework for nuclear liability protection, will bewas extended by twenty years to 2025.
·Federal support will be available for certain clean coal power initiatives, nuclear power projects and renewable energy technologies.

The implementation of the 2005 Energy Act requires proceedings at the state level and the development of regulations, some of which have not been finalized, by the FERC, the DOE and other federal agencies, some of which have not been finalized.agencies. PPL cannot predict when all of these proceedings and regulations will be finalized.

Upon implementation, the Reliability Standards will have the force and effect of law, and will apply to all users of the bulk power electricity system, including electric utility companies, generators and marketers. The FERC has indicated that it intends to vigorously enforce the Reliability Standards using, among other means, civil penalty authority. At this time, PPL cannot predict the impact that compliance with the Reliability Standards will have on PPL, including its capital and operating expenditures, but such compliance costs could be significant.

PPL also cannot predict with certainty the impact of the other provisions of the 2005 Energy Act and any related regulations on PPL and its subsidiaries.

Environmental Matters - Domestic

(PPL, PPL Energy Supply and PPL Electric)

Due to the environmental issues discussed below or other environmental matters, PPL subsidiaries may be required to modify, replace or cease operating certain facilities to comply with statutes, regulations and actions by regulatory bodies or courts. In this regard, PPL subsidiaries also may incur capital expenditures or operating expenses in amounts which are not now determinable, but could be significant.

Air (PPL and PPL Energy Supply)

The Clean Air Act deals, in part, with acid rain, attainment of federal ambient ozone standards, particulate matter standards and toxic air emissions and visibility in the U.S. Amendments to the Clean Air Act requiring additional emission reductions are likely to continue to be brought up for consideration in the U.S. Congress. Past proposed amendments would have required significantThe Clean Air Act allows states to develop more stringent regulations and in some instances, as further reductions in emissions of nitrogen oxide and sulfur dioxide and reductions in emissions of mercury beyond the reductions discussed below, Pennsylvania and some wouldMontana have included reductions in carbon dioxide.
chosen to do so.

Citing its authority under the Clean Air Act, the EPA has developed new standards for ambient levels of ozone and fine particulates in the U.S. These standards have been upheld following court challenges. To facilitate attainment of these standards, the EPA has promulgated the Clean Air Interstate Rule (CAIR) for 28 midwestern and eastern states, including Pennsylvania, to reduce national sulfur dioxide emissions by about 50% by 2010 and to extend the current seasonal program for reduction in emissions of nitrogen oxide emission reductionsoxides to a year-round program starting in 2009. The CAIR requires further reductions, starting in 2015, in sulfur dioxide and nitrogen oxideoxides of 30% and 20%, respectively, from 2010 levels. The CAIR allows these reductions to be achieved through cap-and-trade programs. Pennsylvania has not challenged the CAIR, but the rule has been challenged by several states and environmental groups as not being sufficiently strict, and by industry petitioners as being too strict. In addition, several Canadian environmental groups have petitioned the EPA under the Clean Air Act to revise the CAIR to require deeper reductions in sulfur dioxide and mercury emissions, and the Ozone Transport Commission (consisting of Pennsylvania and 11 other states and the District of Columbia) has passed a resolution calling for reductions in sulfur dioxide and nitrogen oxideoxides that are more stringent than those under CAIR. The Pennsylvania DEP, which represents Pennsylvania on the Ozone Transport Commission, has indicated its support for developing regulations for reductions in sulfur dioxide and nitrogen oxideoxides that are more stringent than those under CAIR.

In order to continue meeting existing sulfur dioxide reduction requirements of the Clean Air Act, including CAIR, PPL is proceeding with the installation ofinstalling sulfur dioxide scrubbers at its Montour Units 1 and 2 and Brunner Island Unit 3, by 2008, and also plans to install a scrubber at Brunner Island Units 1 and 2. The scrubbers for both Montour units and Unit 3 at Brunner Island are expected to be in-service during 2008 and the scrubber for Units 1 and 2 byat Brunner Island is expected to be in-service during 2009. Based on expected levels of generation emission allowance shortfalls that would otherwise occur without significant additional purchases of allowances and projected emission allowance prices, PPL has determined that it is more economic to install these scrubbers than to purchase significant additional emission allowances.allowances to make up the emission allowance shortfalls that would otherwise occur. In order to meet the year-round reductions in nitrogen oxides under CAIR, PPL's current plan is to operate the SCRs at Montour Units 1 and 2 year-round, optimize emission reductions from the existing combustion controls and purchase any needed emission allowances on the open market. PPL's current installation plan for the scrubbers and other pollution control equipment (primarily aimed at sulfur dioxide, particulate, nitrogen oxides and nitrogen oxidemercury emissions reduction) from 2005 to 2010through 2011 reflects a total cost of $1.6approximately $1.5 billion. PPL expects a 30 MW reduction in net generation capability at each of the Brunner Island and Montour plants, due to the estimated increases in station service usage during the scrubber operation.

Also citing its authority under the Clean Air Act, the EPA has finalized mercury regulationsClean Air Mercury Regulations (CAMR) that affect coal-fired plants. These regulations establish an emission tradinga cap-and-trade program to take effect beginningin two phases, with a first phase to begin in January 2010, withand a second phase with more stringent caps to take effectbegin in January 2018. AtUnder CAMR, each state is allocated a mercury emissions cap and is required to develop state implementing regulations that can follow the same time that it finalized these mercury regulations, the EPA determined that it currently does not need to regulate nickel emissions from oil-fired units. PPL is still assessing what measures it will need to take to comply with the mercury regulations. PPL expects that the scrubbers tofederal requirements or be installed at Montour and Brunner Island will provide mercury removal co-benefits. However, PPL believes that it may need to take additional measures to comply with the 2010 requirements of the EPA's mercury regulations and that it will need to take additional measures to comply with the 2018 requirements. The capital costs to PPL of complying with these new mercury regulations are not now determinable, but could be significant. Based on preliminary industry estimates, the costs are expected to exceed $150 million.

more restrictive. Several states, including Pennsylvania, and ten other states have challenged the new EPA mercury regulationsCAMR in the D.C. CircuitU.S. Court of Appeals for the District of Columbia Circuit as not being sufficiently strict. The PPL cannot predict the outcome and impact of that challenge.

Pennsylvania Environmental Quality Board (PaEQB) accepted a petition filed by PennFuture,has adopted its own, more stringent mercury rules. Pennsylvania's rules will require that mercury controls be installed on each coal-fired generating unit; that the EPA's CAMR caps be met at each unit without the benefit of an environmental citizens organization, requestingemissions trading program; and that the PaEQBsecond phase of CAMR be accelerated to developbegin in 2015.

PPL expects that it can achieve the 2010 requirements under Pennsylvania's more stringent mercury rules with only the addition of chemical injection systems. This expectation is based on the co-benefits of mercury removal from the scrubbers expected to be in place at its Pennsylvania plants as of 2010, and the SCRs already in place at Montour. PPL currently estimates that the capital cost of such chemical injection systems at its Pennsylvania plants will be approximately $20 million.

Because an emissions trading program is not allowed under Pennsylvania's mercury rules, adsorption/absorption technology with fabric filters may be required at most of PPL's Pennsylvania coal-fired generating units to meet Pennsylvania's second-phase caps beginning in 2015. Based on current analysis and industry estimates, PPL estimates that if this technology were required at every one of its Pennsylvania units the aggregate capital cost of compliance would be approximately $530 million.

Montana also has finalized its own more stringent rules that would require every coal-fired generating plant in the state to achieve by 2008 a level of mercury2010 reduction that would belevels more stringent than the EPA's regulations,CAMR's 2018 cap. Because enhanced chemical injection technologies may not be sufficiently developed to meet this level of reductions by 2010, there is a risk that adsorption/absorption technology with fabric filters at both Colstrip and the Pennsylvania DEP (which works with the PaEQB to develop Pennsylvania environmental regulations) has circulated for informal stakeholder input a preliminary draft mercury rule that is more stringent than the EPA's regulations but different from those requested by PennFuture. A proposed rule is expected to be released for formal public comment in May 2006.

As a result of a petition to initiate state-specific rulemaking for mercury emissions that was filed by a coalition of environmental and other public interest groups with the Montana Board of Environmental Review (BER) in September 2005, the Montana Department of Environmental Quality (DEQ) is developing a rule to recommend to the BER thatCorette would be more stringent than the EPA's mercury regulations. Therequired. Based on current analysis and industry estimates, PPL estimates that its capital cost to achieve compliance at its Montana BER has authorized the DEQ to move forward with the development of this mercury rule, and the proposed rule is expected tounits would be released for formal public comment by May 2006. At the same time, the DEQ also will request comments on an alternative rule that would adopt the requirements of the EPA's regulations.approximately $140 million.

PPL expects both Pennsylvania's and other energy companiesMontana's mercury rules to be challenged in court. If those rules are overturned and industry groups oppose state-specific regulations that are more stringent than the current federal rules and regulations regarding nitrogen oxide, sulfur dioxide and mercury emissions. PPL cannot predict whether more stringent regulations will ultimately be adopted in Pennsylvania or Montana. The additional costsis instead required to comply with anyCAMR, PPL expects that it could achieve the 2010 requirements under CAMR in both Pennsylvania and Montana with only the addition of chemical injection systems and allowance purchases. In addition to the capital cost for the chemical injection systems in Pennsylvania noted above, PPL estimates that its share of the capital cost for such regulations are not now determinable, butsystems in Montana would be approximately $5 million. With respect to the 2018 requirements under CAMR, PPL currently expects that it would be able to comply in Pennsylvania by installing adsorption/absorption technology with fabric filters on half of its generating capacity at a capital cost of approximately $265 million. In Montana, PPL currently expects that it could be significant.achieve the 2018 CAMR requirements with enhanced chemical injection at modest cost.

In addition to the above rules, the Clean Air Visibility Rule was issued by the EPA on June 15, 2005, to address regional haze or regionally-impaired visibility caused by multiple sources over a wide area. The rule defines Best Available Retrofit Technology (BART) requirements for electric generating units, including presumptive limits for sulfur dioxide and nitrogen oxideoxides controls for large units. In 2007, PPL must submit to the Pennsylvania DEP and to the Montana DEQ its analyses of the visibility impacts of plants covered by the BART rule in each state. In Pennsylvania, this would include Martins Creek Units 3 and 4, Brunner Island Units 2 and 3 and Montour Units 1 and 2. In Montana, this would include Colstrip Units 1 and 2 and Corette. PPL has completed the BART analysis for the Pennsylvania plants and has submitted the analysis to the Pennsylvania DEP.

The EPA has stated that thisthe BART rule will not require states to make reductions in sulfur dioxide or nitrogen oxideoxides beyond those required by CAIR, although states can establish more stringent rules. At this time, PPL cannot predict whether the Pennsylvania DEP will require any such additional reductions beyond the requirements established through CAIR. If the Pennsylvania DEP establishes regulations to require additional reductions, the additional costs to comply with such regulations, which are not now determinable, could be significant.reductions. In states like Montana that are not within the CAIR region, the need for and costscost of additional controls as a result of this new rule are not now determinable, but could be significant.

In 1999, the EPA initiated enforcement actions against several utilities, asserting that older, coal-fired power plants operated by those utilities have, over the years, been modified in ways that subjectsignificantly increased their emissions and subjected them to more stringent "New Source" requirements under the Clean Air Act. The EPA subsequently issued notices of violation and commenced enforcement activities against other utilities. However,In April 2007, the U.S. Supreme Court upheld the annual emissions test under which the EPA had found emissions increases at the plants included in its enforcement initiative.

In the past several years, the EPA has shifted its position on New Source Review. In 2003, the EPA issued changes to its regulations that clarified what projects are exempt from "New Source" requirements as routine maintenance and repair. However, these regulations were stayed and subsequently struck down by the U.S. Court of Appeals for the District of Columbia Circuit. PPL is therefore continuing to operate under the "New Source" regulations as they existed prior to the EPA's 2003 clarifications.

In October 2005, the EPA proposed changing its rules on how to determine whether a project results in an emissions increase and is therefore subject to review under the "New Source" regulations. The EPA's proposed tests are consistent with the position of energy companies and industry groups and, if adopted, would substantially reduce the uncertainties under the current regulations. PPL cannot predict whether these proposed new tests will be adopted. In addition to proposing these new tests, the EPA also announced in October 2005 that it will not bring new enforcement actions with respect to projects that would satisfy the proposed new tests or the EPA's 2003 clarifications referenced above. Accordingly, PPL believes that it is unlikely that the EPA will follow up on the information requests that had been issued to PPL Montana's Corette and Colstrip plants by EPA Region VIII in 2000 and 2003, respectively, and to PPL Generation's Martins Creek plant by EPA Region III in 2002. However, states and environmental groups also have been bringing enforcement actions alleging violations of "New Source" requirements by coal-fired plants, and PPL is unable to predict whether such state or citizens enforcement actions will be brought with respect to any of its affiliates' plants.

The New Jersey DEP and some New Jersey residents raised environmental concerns with respect to the Martins Creek plant, particularly with respect to sulfur dioxide emissions and the opacity of the plant's plume. These issues were raised in the context of an appeal by the New Jersey DEP of the Air Quality Plan Approval issued by the Pennsylvania DEP to PPL's Lower Mt. Bethel generating plant. In October 2003, PPL finalized an agreement with the New Jersey DEP and the Pennsylvania DEP pursuant to which PPL will reduce sulfur dioxide emissions from its Martins Creek power plant.DEP. Under the agreement, PPL Martins Creek will shut down the plant's two 150 MW coal-fired generating units byin September 2007 and may repower them any time after shutting them down so long as it follows all applicable state and federal requirements, including installing the best available pollution control technology.requirements. Pursuant to the agreement, PPL Martins Creek began reducing the fuel sulfur content for the coal units as well as the plant's two oil-fired units in June 2004. The agreement also calls for PPL to donate to a non-profit organization 70% of the excess emission allowances and emission reduction credits that result from shutting down or repowering the coal units. Some of these donations have already been made to the Pennsylvania Environmental Council. As a result of the agreement, the New Jersey DEP withdrew its challenge to the Air Quality Plan Approval for the Lower Mt. Bethel facility. The agreement will not result in material costs to PPL. The agreement does not address the issues raised by the New Jersey DEP regarding the visible opacity of emissions from the oil-fired units at the Martins Creek plant. Similar issues also are being raised by the Pennsylvania DEP. PPL is currently negotiating the matter with the Pennsylvania DEP. If it is determined that actions must be taken to address the visible opacity of these emissions, such actions could result in costs that are not now determinable, but could be significant.

In December 2003, PPL Montana, as operator of the Colstrip facility, received an Administrative Compliance Order (ACO) from the EPA pursuant to the Clean Air Act. The ACO alleges that Units 3 and 4 of the facility have been in violation of the Clean Air Act permit at Colstrip since 1980. The permit required Colstrip to submit for review and approval by the EPA an analysis and proposal for reducing emissions of nitrogen oxideoxides to address visibility concerns upon the occurrence of certain triggering events. The EPA is assertingasserted that regulations it promulgated in 1980 triggered this requirement. PPL believes that the ACO is unfounded. A settlement in this matter has been reached by the parties and is awaiting entry by the U.S. District Court for the District of Montana. The agreement calls for installation of low nitrogen oxides emissions equipment on Colstrip Units 3 and 4, payment of a non-material penalty and financing of an energy efficient project. PPL Montana's cost of this settlement is engaged in settlement negotiations on these matters with the EPA, the Montana DEQ and the Northern Cheyenne Tribe.anticipated to be approximately $4 million.

In addition to the requirements related to emissions of sulfur dioxide, nitrogen oxide and mercury noted above, thereThere is a growing concern nationally and internationally about global climate change and the contribution of emissions of greenhouse gases, including most significantly, carbon dioxide. This concern has led to increased interest in legislation at the federal level, actions at the state level, as well as litigation relating to greenhouse gas emissions, including the recent Supreme Court decision holding that the EPA has the authority to regulate carbon dioxide emissions. Inemissions from motor vehicles under the Clean Air Act. Increased pressure for carbon dioxide emissions reduction also is coming from investor organizations and the international community.
On the legislative front, in June 2005, the U.S. Senate adopted a resolution declaring that mandatory reductions in carbon dioxidegreenhouse gases are needed. Various legislative proposalsSeveral bills that would cap or tax greenhouse gases from electric utilities are being considered inby Congress, and several states already have passed legislation capping carbon dioxide emissions. Thethe concept of such regulation has received support from the majority leadership in both the U.S. Senate and U.S. House of Representatives.  President Bush administration ishas opposed such regulation, promoting instead a voluntary carbon dioxidegreenhouse gas reduction program, called the Climate VISION program. In support of this program,

At the electric power industry has committed to reducing its greenhouse gas emission intensity levels (measured as tons of carbon dioxide equivalent against electric power production in MWh) by 3% to 5% by the 2010 to 2012 period. Separate from the national initiatives, in December 2005,state level, seven northeastern states signed an MOU establishingin 2005, agreeing to establish a cap and trade program, called the Regional Greenhouse Gas Initiative (RGGI), commencing in January 2009 for stabilization of carbon dioxide emissions, at base levels established in 2005, from electric power plants larger than 25 MW in capacity. In April 2006 Maryland's governor signed a bill that will have the state participating in this same program (known as the Regional Greenhouse Gas Initiative) by June 2007. The MOU also provides for a 10% reduction in carbon dioxide emissions from the base levels by the end of 2018. Increased pressureIn August 2006, a Model Rule was developed by these seven states that will form the basis for participants to adopt individual state laws and regulations for program implementation. Three other states have subsequently joined RGGI, and several other states are considering joining. A similar effort is under way in the western part of the country with California and several other states also having announced their intention to develop a cap-and-trade program for carbon dioxide emissions reduction also is coming from investor organizations and the international community.dioxide.

Pennsylvania and Montana have not, at this time, established any formalmandatory programs to addressregulate carbon dioxide and other greenhouse gases. However, government officials in each state have declared support for state action on climate change issues. PPL has conducted an inventory of its carbon dioxide emissions and is continuing to evaluate various options for reducing, avoiding, off-setting or sequestering its carbon dioxide emissions. If Pennsylvanialegislation or Montana develop regulations are passed at the federal or state levels imposing mandatory reductions of carbon dioxide and other greenhouse gases on generation facilities, the cost to PPL of such reductions could be significant.

Water/Waste (PPL and PPL Energy Supply)

In August 2005, there was a leakrelease of approximately 100 million gallons of water containing fly ash from a disposal basin containing fly ash and waterat the Martins Creek plant used in connection with the operation of the two 150-MW150 MW coal-fired generating units at the Martins Creek generating facility caused the discharge of 100 million gallons of water containingplant. This resulted in ash from the basinbeing deposited onto adjacent roadways and fields, and into a nearby creek and the Delaware River. The leak was stopped, and PPL has determined that the problem was caused by a failure in the disposal basin's discharge structure. PPL has conducted extensive clean-up and is continuing to work with the Pennsylvania DEP and other appropriate agencies and consultants to assess the extent of the ash remaining in the river and whether the releaseleak caused any environmental damage. PPL shut down the two coal-fired generating units in September 2005 and placed the units back in service in December 2005 after completing the repairs and upgrades to the basin and obtaining the Pennsylvania DEP's approval.

In September 2005, PPL Martins Creek and the Pennsylvania DEP were served with notice by the Delaware Riverside Conservancy and several citizens of their intention to file a citizens' suit on the basis that the leak from the disposal basin at Martins Creek allegedly violated various state and federal laws. The Pennsylvania DEP subsequently filed a complaint in Commonwealth courtCourt against PPL Martins Creek and PPL Generation, alleging violations of various state laws and regulations and seeking penalties and injunctive relief. The Delaware Riverside Conservancy and several citizens have been granted the right, without objection from PPL, to intervene in the Pennsylvania DEP's action. PPL intends to engage in settlement discussions to resolveand the Pennsylvania DEP action. In March 2006,have reached a tentative settlement for the Delaware Riverside Conservancyalleged violations. The proposed settlement requires PPL to pay $1.5 million in penalties and several citizens also filed a purported class action lawsuit in the Superior Court of New Jersey, Warren County, alleging that the fly ash spill caused damages to property along a 40-mile stretchreimbursement of the Delaware River. This lawsuit has not yet been servedDEP's costs, and requires PPL to submit a report on PPL.

At this time,the completed studies of possible natural resource damages. PPL has no reason to believe thatbeen doing the Martins Creek leak has caused any danger to human health or any adverse biological impact on the river aquatic life. However,studies in conjunction with a group of natural resource trustees, along with the Delaware River Basin Commission, has been conducting an assessment of any natural resource damages that could have been caused by the Martins Creek leak.Commission. PPL expects the trustees and the Delaware River Basin Commission to seek to recover their costs as well asand/or any damages they determine were caused by the leak. PPL cannot predict whenis implementing a study plan under which the assessment will be completed but doesand reported to the agencies by May 2007. Studies to date do not expect itshow damages attributable to be completed before the end of 2006.leak. However, the agencies may require additional studies.

In March 2006, several citizens (including some that have intervened in the Pennsylvania DEP's lawsuit) and two businesses filed a lawsuit in the Superior Court of New Jersey, Warren County, alleging that the fly ash leak caused damage to property along a 40-mile stretch of the Delaware River and asserting that the named plaintiffs are representative of a class of citizens and businesses along the 40-mile stretch of the Delaware River. PPL moved this lawsuit to federal court in New Jersey and the plaintiffs thereafter voluntarily withdrew their action without prejudice to bring an action in state court that is not a class action.

During 2005, PPL Energy Supply recognized a $33$48 million pre-tax charge in the third quarter of 2005 and an additional $15 million pre-tax charge in the fourth quarter of 2005 (or a total of $31($31 million after tax, or $0.08 per share for PPL)tax) in connection with the then-expected on-site and off-site costs relating to the remediation. Based on its ongoing assessment of the expected remediation costs, in the first quarter of 2006 PPL Energy Supply reduced the estimate in connection with the current expected costs of the leak by $3 million, of which $2 million relates to off-site costs and the remainder to on-site costs. This reduction was included in "Other operation and maintenance" on the Statement of Income. During the remainder of 2006, PPL Energy Supply further reduced its estimate in connection with the current expected costs of the leak by $8 million. At March 31, 2006, $392007, management's best estimate of the probable loss associated with the Martins Creek ash basin leak remains at $37 million, of the $45which $31 million estimate relates to the off-site costs, and the $6 million balance of the total charge relates to the on-site costs. At March 31, 2007, the remaining contingency for this remediation was $9 million. PPL and PPL Energy Supply cannot predict the final costbe certain of assessment and remediation of the leak, the outcome of the action initiated by the Pennsylvania DEP, the outcome of the natural resource damage assessment, the outcome of any lawsuit brought by the citizens and businesses and the exact nature of any other regulatory or other legal actions that may be initiated against PPL, PPL Energy Supply or their subsidiaries as a result of the disposal basin leak. PPL and PPL Energy Supply also cannot predict the extent of the fines or damages that may be sought in connection with any such actions or the ultimate financial impact on PPL or PPL Energy Supply.

Seepages have been detected at active and retired wastewater basins at various PPL plants, including the Montour, Brunner Island and Martins Creek generating facilities. PPL has completed an assessment of some of the seepages at the Montour and Brunner Island facilities and is working with the Pennsylvania DEP to implement abatement measures for those seepages. PPL is continuing to conduct assessments of other seepages at the Montour and Brunner Island facilities as well as seepages at the Martins Creek facility to determine the appropriate abatement actions. PPL plans to comprehensively address issues related to wastewater basins at all of its Pennsylvania plants, as part of the process to renew the residual waste permits for these basins that expire within the next threetwo years. PPL has a remaining contingency of $1 million to assess and/or abate seepage from certain facilities and has $5 million in the 2007 capital budget to upgrade and/or replace certain waste water facilities in response to the seepage and other facility changes. The potential cost of addressingto address other seepages or to replace existing wastewater basins at PPL's Pennsylvania plants is not now determinable, but could be significant.

PPL has reached a settlement with the Pennsylvania DEP concerning the thermal discharge from its Brunner Island plant into the Susquehanna River. The settlement commits PPL to install mechanical draft cooling towers at the plant. PPL expects construction of the cooling towers to begin by the end of 2007 and for the towers to be in service in the spring of 2010. The expected capital cost of the installation of the towers is $125 million.

In May 2003, approximately 50 plaintiffs brought an action now pending at the Montana Sixteenth Judicial District Court, Rosebud County, against PPL Montana and the other owners of the Colstrip plant alleging property damage from seepage from the freshwater and wastewater ponds at Colstrip. In February 2007, six plaintiffs filed a separate lawsuit in the same court against the Colstrip plant owners asserting similar claims. PPL Montana has undertaken certain groundwater investigation and remediation measures at the Colstrip plant to address groundwater contamination alleged by the plaintiffs as well as other groundwater contamination at the plant. These measures include proceeding with extending city water to certain residents who live near the plant, some of whom are plaintiffs in the original litigation. Beyond the original estimated reserve of $1 million recorded by PPL Montana in 2004 (of which only an insignificant amount remains at March 31, 2006)2007) for a proposed settlement of the property damage claims raised in the original litigation, for extending city water and for a portion of the remedial investigation costs, PPL Montana may incur further costs based on its additional groundwater investigations and any related remedial measures, which costs are not now determinable, but could be significant.

PPL has been in discussions with the Pennsylvania DEP concerning the thermal discharges from its Brunner Island plant into the Susquehanna River. The matter has now been settled with PPL's commitment to install mechanical draft cooling towers at the plant. PPL expects construction of the cooling towers to begin by the end of 2007 and for the towers to be in service in the spring of 2010. The expected capital cost of the installation of the towers is approximately $125 million.

The EPA has significantly tightened the water quality standard for arsenic. The revised standard became effective in January 2006 and at this time applies only to drinking water. The revised standard may result in action by individual states that could require several PPL subsidiaries to either further treat wastewater or take abatement action at their power plants, or both. The cost of complying with any such requirements is not now determinable, but could be significant.

The EPA finalized requirements in 2004 for new or modified cooling water intake structures. These requirements affect where generating facilities are built, establish intake design standards, and could lead to requirements for cooling towers at new and modified power plants. Another new rule that was finalized in 2004 addresses existing structures. PPL does not believe that either of these rules will impose material costs on PPL subsidiaries. However, sixSix northeastern states have challenged the new rules for existing structures as being inadequate. IfIn January 2007, the U.S. Court of Appeals for the Second Circuit remanded to the EPA all of the main requirements of the rule for further analysis and rulemaking. Depending on what changes the EPA makes to the rule in accordance with this challenge is successful, itdecision, and/or what actions the states may take on their own, the impacts of the actions could result in the EPA establishing stricter standards for existing structures that could impose significant costs on PPL subsidiaries.

Superfund and Other Remediation

(PPL, PPL Energy Supply and PPL Electric)

PPL Electric is a potentially responsible party at several sites listed by the EPA under the federal Superfund program, including the Columbia Gas Plant Site. Clean-up actions have been or are being undertaken at all of these sites, the costs of which have not been significant. However, should the EPA require significantly different or additional measures in the future, the costs of such measures are not determinable but could be significant.

In 1995, PPL Electric and PPL Generation and, in 1996, PPL Gas Utilities entered into consent orders with the Pennsylvania DEP to address a number of sites that were not being addressed under another regulatory program such as Superfund, but for which PPL Electric, PPL Generation or PPL Gas Utilities may be liable for remediation. This may includeThese agreements have now been combined into a single agreement for the companies. The Consent Order and Agreement (COA) includes potential PCB contamination at certain PPL Electric substations and pole sites; potential contamination at a number of coal gas manufacturing facilities formerly owned or operated by PPL Electric; oil or other contamination that may exist at some of PPL Electric's former generating facilities; and potential contamination at abandoned power plant sites owned by PPL Generation. This may also includeincludes former coal gas manufacturing facilities and potential mercury contamination from gas meters and regulators at PPL Gas Utilities' sites.

Since the PPL Electric Consent Order expired on January 31, 2005, and since only four sites remained, PPL has negotiated a new consent order and agreement (COA) with the Pennsylvania DEP that combines both PPL Electric's and PPL Gas Utilities' consent orders into one single agreement. As of March 31, 2006,2007, PPL Electric and PPL Gas Utilities have 148118 sites (97 well-plugging sites and 21 sites requiring remediation as discussed above) to address under the new combined COA, and currently no PPL Generation sites are included on the COA site list. Additional sites formerly owned or operated by PPL Electric, PPL Generation or PPL Gas Utilities are added to the consent ordersCOA on a case-by-case basis.

At March 31, 2006,2007, PPL Electric and PPL Gas Utilities had accrued $2$3 million and $5$9 million, respectively, representing the estimated amounts each will have to spend for site remediation, including those sites covered by each company's consent orders mentionedthe COA noted above. Depending on the outcome of investigations at sites where investigations have not begun or have not been completed, the costs of remediation and other liabilities could be substantial. PPL and its subsidiaries also could incur other non-remediation costs at sites included in the consent orders or other contaminated sites, the costs of which are not now determinable, but could be significant.

There continues to be an issue with natural gas observed in several drinking water wells in and around Tioga County, Pennsylvania, that the Pennsylvania DEP has been working to address. The Pennsylvania DEP has raised concerns regardingthat potential leakage of natural gas from the Tioga gas storage field partially owned by PPL Gas Utilities. The Pennsylvania DEP believes gas is leaking from the storage field and causing methane impactsUtilities could be contributing to nearby residential wells. While PPL Gas has no evidence to confirm or deny the Pennsylvania DEP's position,this issue. PPL Gas Utilities has initiated a plancontinues to identifywork with the Pennsylvania DEP and address potential sources of gas leakage from the field. PPL Gas Utilities is discussingto discuss the matter with the co-owner and operator of the field and with the Pennsylvania DEP.field. The costs to resolve this issue are not now determinable, but could be significant.

The EPA is evaluating the risks associated with naphthalene, a chemical by-product of coal gas manufacturing operations. As a result of the EPA's evaluation, individual states may establish stricter standards for water quality and soil clean-up. This could require several PPL subsidiaries to take more extensive assessment and remedial actions at former coal gas manufacturing facilities. The costs to PPL of complying with any such requirements are not now determinable, but could be significant.

(PPL and PPL Energy Supply)

Under the Pennsylvania Clean Streams Law, subsidiaries of PPL Generation are obligated to remediate acid mine drainage at former mine sites and may be required to take additional measures to prevent potential acid mine drainage at previously capped refuse piles. One PPL Generation subsidiary is pumping and treating mine water at two mine sites, and treating water at one of these sites. Another PPL Generation subsidiary is installinghas installed a passive wetlands treatment system at a third site, and the Pennsylvania DEP has suggested that it may require that PPL Generation subsidiary to pump and treat the mine water at that third site. At March 31, 2006, a2007, PPL Energy Supply subsidiary had accrued $28a discounted liability of $30 million to cover the costs of pumping and treating groundwater at the two mine sites for 50 years and for operating and maintaining passive wetlands treatment at the third site. PPL Energy Supply discounted this liability at a rate of 5.82%. Expected undiscounted payments are estimated at $1 million for each of the years from 2007 through 2011, and the expected payments for the work after 2011 are $116 million.

In 1999, the Montana Supreme Court held in favor of several citizens' groups that the right to a clean and healthful environment is a fundamental right guaranteed by the Montana Constitution. Currently pending before the Court are three cases relating to the manner in which this fundamental right may be exercised and the proper measurement of damages for environmental impacts to property. These cases were consolidated for purposes of arguments before the Court. The court'sCourt's ruling on this consolidated litigation could result in significantly more stringent environmental laws and regulations, as well as an increase in citizens' suitslawsuits under Montana's environmental laws. The effect on PPL Montana of any such changes in laws or regulations or any such increase in legal actions is not currently determinable, but could be significant.

(PPL, PPL Energy Supply and PPL Electric)

Future cleanup or remediation work at sites currently under review, or at sites not currently identified, may result in material additional operating costs for PPL subsidiaries that cannot be estimated at this time.

Asbestos(PPL and PPL Energy Supply)

There have been increasing litigation claims throughout the U.S. based on exposure to asbestos against companies that manufacture or distribute asbestos products or that have these products on their premises. A PPL generation subsidiary has minority interests in two generation plants that currently are involved in asbestos-related lawsuits, and certain PPL energy services subsidiaries, such as those that have supplied, may have supplied or installed asbestos material in connection with the repair or installation of process piping and heating, ventilating and air conditioning systems, from time to time have been named as defendants in asbestos-related lawsuits. PPL cannot predict the outcome of any of these existing asbestos-related lawsuits or whether additional claims may be asserted against its subsidiaries or such generation plants in the future. PPL believes that all claims under current asbestos-related lawsuits naming its energy services subsidiaries as defendants are covered by insurance. Even in the absence of insurance coverage for the existing lawsuits naming its subsidiaries as defendants or involving such generation plants, PPL does not believe at this time that there is a reasonable possibility that the resolution of these lawsuits will have a material adverse effect on its financial condition or results of operations.

Electric and Magnetic Fields (PPL, PPL Energy Supply and PPL Electric)

Concerns have been expressed by some members of the public regarding potential health effects of power frequency EMFs, which are emitted by all devices carrying electricity, including electric transmission and distribution lines and substation equipment. Government officials in the U.S. and the U.K. have reviewed this issue. The U.S. National Institute of Environmental Health Sciences concluded in 2002 that, for most health outcomes, there is no evidence of EMFs causing adverse effects. The agency further noted that there is some epidemiological evidence of an association with childhood leukemia, but that this evidence is difficult to interpret without supporting laboratory evidence. The U.K. National Radiological Protection Board (now part of the U.K. Health Protection Agency) concluded in 2004 that, while the research on EMFs does not provide a basis to find that EMFs cause any illness, there is a basis to consider precautionary measures beyond existing exposure guidelines. PPL and its subsidiaries believe the current efforts to determine whether EMFs cause adverse health effects should continue and are taking steps to reduce EMFs, where practical, in the design of new transmission and distribution facilities. PPL and its subsidiaries are unable to predict what effect, if any, the EMF issue might have on their operations and facilities either in the U.S. or abroad, and the associated cost, or what, if any, liabilities they might incur related to the EMF issue.

Environmental Matters - International (PPL and PPL Energy Supply)

U.K.

WPD's distribution businesses are subject to numerous regulatory and statutory requirements with respect to environmental matters. PPL believes that WPD has taken and continues to take measures to comply with the applicable laws and governmental regulations for the protection of the environment. There are no material legal or administrative proceedings pending against WPD with respect to environmental matters. See "Environmental Matters - Domestic - Electric and Magnetic Fields" for a discussion of EMFs.

Latin America

Certain of PPL's affiliates have electric distribution operations in Latin America. PPL believes that these affiliates have taken and continue to take measures to comply with the applicable laws and governmental regulations for the protection of the environment. There are no material legal or administrative proceedings pending against PPL's affiliates in Latin America with respect to environmental matters.

Other

Nuclear Insurance (PPL and PPL Energy Supply)

PPL Susquehanna is a member of certain insurance programs that provide coverage for property damage to members' nuclear generating stations. Facilities at the Susquehanna station are insured against property damage losses up to $2.75 billion under these programs. PPL Susquehanna is also a member of an insurance program that provides insurance coverage for the cost of replacement power during prolonged outages of nuclear units caused by certain specified conditions. Under the property and replacement power insurance programs, PPL Susquehanna could be assessed retroactive premiums in the event of the insurers' adverse loss experience. At March 31, 2006,2007, this maximum assessment was about $38 million.

In the event of a nuclear incident at the Susquehanna station, PPL Susquehanna's public liability for claims resulting from such incident would be limited to about $10.8 billion under provisions of The Price AndersonPrice-Anderson Act Amendments under the Energy Policy Act of 2005. PPL Susquehanna is protected against this liability by a combination of commercial insurance and an industry assessment program. In the event of a nuclear incident at any of the reactors covered by The Price AndersonPrice-Anderson Act Amendments under the Energy Policy Act of 2005, PPL Susquehanna could be assessed up to $201 million per incident, payable at $30 million per year.

The exposure noted is only for those cases in which the agreements provide for a specific limit on the amount of the indemnification.
In connection with the liquidation of wholly owned subsidiaries that have been deconsolidated upon turning the entities over to the liquidators, certain affiliates of PPL Global have agreed to indemnify the liquidators, directors and/or the entities themselves for any liabilities or expenses arising during the liquidation process, including liabilities and expenses of the entities placed into liquidation. In some cases, the indemnifications are limited to a maximum amount that is based on distributions made from the subsidiary to its parent either prior or subsequent to being placed into liquidation. In other cases, the maximum amount of the indemnifications is not explicitly stated in the agreements. The indemnifications generally expire two to seven years subsequent to the date of dissolution of the entities. The exposure noted only includes those cases in which the agreements provide for a specific limit on the amount of the indemnification, and the expiration date was based on an estimate of the dissolution date of the entities.
Certain of the indemnifications provided to the purchaser of the Sundance plant are triggered only if the purchaser's losses reach $1 million in the aggregate, are capped at 50% of the purchase price (or $95 million), and survive for a period of only 24 months after the May 13, 2005, transaction closing. The indemnification provision for unknown environmental and tort liabilities related to periods prior to the ownership by PPL Sundance Energy, Supply's ownershipLLC of the real property on which the facilitySundance plant is located are capped at $4 million in the aggregate and survive for a maximum period of five years after the transaction closing.
Certain of the indemnifications provided to the purchaser of the interest of PPL Southwest Generation Holdings, LLC in the Griffith plant are triggered only if the purchaser's losses reach $750,000 in the aggregate, are capped at 35% of the purchase price (or $41 million), and survive for a period of only 18 months after the June 30, 2006, transaction closing. In the case of most such indemnification obligations, the purchaser's existing 50% ownership of the Griffith plant prior to closing is taken into account for purposes of determining and calculating the purchaser's losses, and such indemnification obligations are therefore limited to 50% of any such purchaser losses.
(i)In July 2006, two subsidiaries of PPL Energy Supply assigned their Enron claims to an independent third party (claims purchaser). In connection with the assignment, the subsidiaries agreed to repay a pro rata share of the purchase price paid by the claims purchaser, plus interest, in the event that any of the assigned claims are disallowed under certain circumstances. The bankruptcy court overseeing the Enron bankruptcy approved the assigned claims prior to their assignment to the claims purchaser. The subsidiaries' repayment obligations will remain in effect until the claims purchaser has received all distributions with respect to the assigned claims.
(j)Two WPD unconsolidated affiliates were refinanced during 2005. Under the terms of the refinancing, WPD has indemnified the lender against certain tax and other liabilities. At this time, WPD believes that the likelihood of such liabilities arising is remote.
(k)Reflects principal payments only.

PPL, PPL Energy Supply and PPL Electric and their subsidiaries provide other miscellaneous guarantees through contracts entered into in the normal course of business. These guarantees are primarily in the form of various indemnifications or warranties related to services or equipment and vary in duration. The obligated amounts of these guarantees often are not explicitly stated, and the overall maximum amount of the obligation under such guarantees cannot be reasonably estimated. Historically, PPL, PPL Energy Supply and PPL Electric and their subsidiaries have not made any significant payments with respect to these types of guarantees. As of March 31, 2006,2007, the aggregate fair value of these indemnifications related to arrangements entered into subsequent to December 31, 2002, was insignificant.

Credit Concentration

(PPL and PPL Energy Supply)

PPL and PPL Energy Supply enter into contracts with many entities for the purchase and sale of energy. Many of these contracts are considered a normal part of doing business and, as such, the mark-to-market value of these contracts is not reflected in the financial statements. However, the mark-to-marketfair value of these contracts is considered when committing to new business from a credit perspective.

PPL and PPL Energy Supply have credit exposures to energy trading partners. The majority of these exposures areis the mark-to-marketfair value of multi-year contracts for energy sales and purchases. Therefore, if these counterparties fail to perform their obligations under such contracts, PPL and PPL Energy Supply would not experience an immediate financial loss but would experience lower revenues or higher costs in future years to the extent that replacement sales or purchases could not be made at the same prices as those under the defaulted contracts.

At March 31, 2006, PPL had a credit exposure of $416 million to energy trading partners. Ten counterparties accounted for 77% of this exposure. No other individual counterparty accounted for more than 3% of the exposure. Nine of the ten counterparties had an investment grade credit rating from S&P. One counterparty was not rated by any of the major credit rating agencies but was current on its obligations.

No other individual counterparty accounted for more than 3% of the exposure. Nine of the ten counterparties had an investment grade credit rating from S&P. One counterparty was not rated by any of the major credit rating agencies but was current on its obligations.

PPL and PPL Energy Supply generally have the right to request collateral from their counterparties in the event that the counterparties' credit ratings fall below investment grade.grade or their exposure exceeds an established credit limit. It is also the policy of PPL and PPL Energy Supply to enter into netting agreements with all of their counterparties to limit credit exposure.

At March 31, 2007, both PPL and PPL Energy Supply had a credit exposure of $378 million to energy trading partners, excluding the effects of netting arrangements. No individual counterparty accounted for more than 12% of the exposure. Ten counterparties accounted for $260 million, or 69%, of the total exposure. Eight of these counterparties had an investment grade credit rating from S&P and accounted for 87% of the top 10 exposure. As a result of netting arrangements and forward market prices, PPL's and PPL Energy Supply's credit exposure was reduced to zero.

(PPL Electric)

PPL Electric has an exposure to PPL Energy Supply under the long-term contract for PPL EnergyPlus to supply PPL Electric's PLR load, as described in Note 12.11. This is the only credit exposure for PPL Electric that has a mark-to-market element. No other counterparty accounts for more than 1% of PPL Electric's total exposure.

Funds in the nuclear decommissioning trust are legally restricted for purposes of settling PPL's and PPL Energy Supply's ARO related to the decommissioning of the Susquehanna station. PPL Electric collects authorized nuclear decommissioning costs through the CTC. These revenues are passed on to PPL EnergyPlus under the power supply agreements between PPL Electric and PPL EnergyPlus. Similarly, these revenues are passed on to PPL Susquehanna under a power supply agreement between PPL EnergyPlus and PPL Susquehanna. These revenues, less applicable taxes, are used to fund the nuclear plant decommissioning trust funds and can only be used for future decommissioning costs. The aggregate fair value of the nuclear plant decommissioning trust funds was $463$520 million as of March 31, 2006,2007, and $444$510 million as of December 31, 2005.2006.

New Accounting Standards

(PPL, PPL Energy Supply and PPL Electric)

FSP No. FIN 46(R)-648

In AprilJune 2006, the FASB issued FIN 48, "Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109." In May 2007, the FASB amended this guidance by issuing FSP No. FIN 46(R)-6, "Determining the Variability to Be Considered48-1, "Definition of Settlement in Applying FASB Interpretation No. 46(R).48." FSP No. FIN 46(R)-6 provides that the variability to be considered in applying FIN 46 (revised December 2003), "Consolidation of Variable Interest Entities, an Interpretation of ARB 51," (FIN 46(R)) should be based on the design of the entity involved. PPL and its subsidiaries will adopt the provisions of FSP No. FIN 46(R)-6 prospectively no later than July 1, 2006. Retrospective application to the date of the initial application of FIN 46(R) is permitted but not required. PPL and its subsidiaries do not plan to apply retrospective application to any period prior to the date of adoption. The adoption of FSP No. FIN 46(R)-6 is not expected to have a material impact on PPL and its subsidiaries.  However, the impact in periods subsequent to adoption could be material.

SFAS 123(R)

In December 2004, the FASB issued SFAS 123 (revised 2004), "Share-Based Payment," which is known as SFAS 123(R) and replaces SFAS 123, "Accounting for Stock-Based Compensation," as amended by SFAS 148, "Accounting for Stock-Based Compensation-Transition and Disclosure." Among other things, SFAS 123(R) eliminates the alternative to use the intrinsic value method of accounting for stock-based compensation. SFAS 123(R) requires public entities to recognize compensation expense for awards of equity instruments to employees based on the grant-date fair value of the awards.

PPL and its subsidiaries adopted SFAS 123(R)FIN 48, as amended, effective January 1, 2006. PPL and its subsidiaries applied the modified prospective application transition method of adoption. Under this application, entities must recognize compensation expense based on the grant-date fair value for new awards granted or modified after the effective date and for unvested awards outstanding on the effective date. The adoption of SFAS 123(R) did not have a significant impact on PPL and its subsidiaries, since PPL and its subsidiaries adopted the fair value method of accounting for stock-based compensation, as described by SFAS 123, effective January 1, 2003.2007. See Note 95 for the disclosures required by SFAS 123(R).FIN 48. 

SFAS 155

In February 2006, the FASB issued SFAS 155, "Accounting for Certain Hybrid Financial Instruments, an amendment of FASB Statements No. 133 and 140." Among other items,things, SFAS 155 addresses certain accounting issues surrounding securitized financial assets and hybrid financial instruments with embedded derivatives that require bifurcation. PPL and its subsidiaries mustadopted SFAS 155 effective January 1, 2007. The adoption of SFAS 155 did not have an impact on PPL and its subsidiaries.

SFAS 157

In September 2006, the FASB issued SFAS 157, "Fair Value Measurements." SFAS 157 provides a definition of fair value as well as a framework for measuring fair value. In addition, SFAS 157 expands the fair value measurement disclosure requirements of other accounting pronouncements to require, among other things, disclosure of the methods and assumptions used to measure fair value as well as the earnings impact of certain fair value measurement techniques. SFAS 157 does not expand the use of fair value measurements in existing accounting pronouncements. PPL and its subsidiaries will adopt SFAS 155 no later than157 prospectively, effective January 1, 2007.2008, except for certain items such as financial instruments that were previously measured at fair value in accordance with footnote 3 of EITF Issue No. 02-3, "Issues Involved in Accounting for Derivative Contracts Held for Trading Purposes and Contracts Involved in Energy Trading and Risk Management Activities," which require a limited form of retrospective application. PPL and its subsidiaries are currently in the process of performingevaluating the impact of adopting SFAS 157. The potential impact of adoption is not yet determinable, but it could be material.

SFAS 159

In February 2007, the FASB issued SFAS 159, "The Fair Value Option for Financial Assets and Financial Liabilities—including an amendment of FASB Statement No. 115." SFAS 159 provides entities with an option to measure, upon adoption of this pronouncement and at specified election dates, certain financial assets and liabilities at fair value, including available-for-sale and held-to-maturity securities, as well as other eligible items. The fair value option (i) may be applied on an instrument-by-instrument basis, with a complete assessmentfew exceptions, (ii) is irrevocable (unless a new election date occurs), and (iii) is applied to an entire instrument and not to only specified risks, cash flows, or portions of that instrument. An entity shall report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date.

SFAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between similar assets and liabilities measured using different attributes. Upon adoption of SFAS 155. However, since 159, an entity may elect the fair value option for eligible items that exist at that date, and must report the effect of the first remeasurement to fair value as a cumulative-effect adjustment to the opening balance of retained earnings.
PPL and its subsidiaries do not have any interestswill adopt SFAS 159 effective January 1, 2008. PPL and its subsidiaries are in securitized financial assets or hybrid financial instruments with embedded derivatives that require bifurcation,the process of evaluating the impact from theof adopting SFAS 159. The potential impact of adoption of SFAS 155 is not expected toyet determinable, but it could be material.

·See "Domestic Gross Energy Margins" for an explanation of non-trading margins by geographic region and for an explanation of net energy trading margins.
  
·Higher operation and maintenance expenses were primarily due to the nuclear refueling outage and inspection costs at the Susquehanna station and outages at the Brunner Island and Martins Creek plants in 2006. The costs of these outages exceeded the costs of the 2005 planned outage at Montour and a short-duration outage at the Susquehanna station.
·The improved earnings contribution from synfuel projects resulted from an unrealized gain on options purchased to hedge a portionwas primarily the result of the risk associated with the phase-out of the synthetic fuel tax credits for 2006 and 2007, partially offset by the lower recognition of synthetic fuel tax credits due to the anticipatedassumed phase-out of synthetic fuel tax credits startingfor the three months ended March 31, 2007, compared with the same period in 2006.
·In the first quarter of 2006, PPL lowered its reserve on claims related to the Enron bankruptcy. This adjustment increased earnings by $9 million after-tax (or $0.03 per share). See Note 2 to the Financial Statements for additional information.
·In the first quarter of 2005, PPL recognized a charge of $6 million after tax (or $0.02 per share) for a loss contingency related to litigation with NorthWestern. In September 2005, PPL and NorthWestern reached a final agreement to settle this litigation.

2007 Outlook

PPL projects significantly higher earnings in its Supply business segment in 2007 compared with 2006. Based on current forward energy prices and hedges already in place, PPL is projecting higher energy margins for its Supply segment in 2006 comparedthe balance of 2007, driven primarily by the replacement of expiring supply obligations with 2005. This increase is primarily driven by an 8.4% increase in PLR sale prices. Higher generation output and higher-pricedhigher-margin wholesale energy contracts, that replace expiringsuch as the contract with NorthWestern in Montana, as well as new full-requirements contracts also arein the Mid-Atlantic region.

While PPL expects improved baseload power plant performance in 2007, this performance will be offset by the retirement in September of two small coal-fired units in Pennsylvania and by planned outages, including the Susquehanna Unit 1 outage, which is expected to conclude the control rod friction issues that have affected plant operations over the past several years. PPL believes these planned outages will improve energy margins. These benefits are expected to be partially offset bythe overall long-term reliability of its generation fleet. PPL also expects a modest increase in fuel-related expenses and increased fuel and fuel transportation expenses, higher operation and maintenance expenses and reduced earnings from synfuel projects.

See "Regulatory Issues - IRS Synthetic Fuels Tax Credits" in Note 11 to the Financial Statements for a discussion of the tax credits that PPL has earned in connection with its synfuel projects and the impact of higher oil prices on future tax credits. In early April 2006, PPL suspended operations at one of its two synfuel projects based upon increased oil prices and the potential phase-out of these tax credits under existing tax rules. For these same reasons, PPL currently expects to suspend operations at its other synfuel project in mid-2006.

PPL had projected an earnings contribution from the combination of synfuel projects and synthetic fuel-related hedges of $39 million (or $0.10 per share) in 2006.  Based upon projected production levels reflecting the suspension of PPL's synthetic fuel operations as discussed above and assuming the continued suspension for the remainder of 2006, PPL's earnings from the combination of synfuel projects and synthetic fuel-related hedges would be $19 million (or $0.05 per share) in 2006.

In addition to producing synthetic fuel, PPL also purchases synthetic fuel from unaffiliated third parties, at prices below the market price of coal, for use at its coal-fired power plants. PPL estimates that if these third parties had discontinued their synthetic fuel operations and sales to PPL at the end of April 2006 due to the impact of projected oil prices, the company would incur additional fuel costs of $16 million ($9 million after tax, or $0.02 per share) for the remainder of 2006.

There currently are legislative proposals pending in the U.S. Congress that could affect the potential phase-out of the synthetic fuel tax credits for 2006 and 2007. At this time, PPL cannot predict whether any such legislation will be enacted or the impact of any such legislation on its synthetic fuel operations or tax credits in 2006 or 2007.

The net carrying value of the property, plant and equipment and intangible assets associated with PPL's two synfuel projects was $12 million at March 31, 2006. As of March 31, 2006, the estimated phase-out of synthetic fuel tax credits, based on forward oil prices as of that date, did not result in these assets being impaired. However, these estimates can change significantly due to the volatility in oil prices as well as the potential impact of pending legislation, which could result in an impairment of the synfuel project assets that would otherwise be depreciated or amortized in 2006 and 2007. PPL will continue to assess the status of its synfuel projects as changes in oil prices, legislation and other factors occur.expenses.

International Delivery Segment

The International Delivery segment includes operations of the international energy businesses of PPL Global that are primarily focused on the distribution of electricity. Substantially all of PPL Global's international businesses are located in the U.K., Chile, El Salvador and Bolivia.

The International Delivery segment results in the first quarter of 2007 and 2006 reflect the reclassification of Latin American revenues and expenses to "(Loss) Income From Discontinued Operations." See Note 8 to the Financial Statements for further discussion.

2007 Outlook
PPL projects the earnings from its International Delivery business segment to decline in 20062007 compared with 2005, primarily resulting from2006. Higher delivery margins in the U.K., due to higher pension costs at WPD,unit prices, are expected to be more than offset by increased operating expenses and higher U.S. income taxes and a potential unfavorable change in foreign currency exchange ratesthe U.K. in 2007, due to the favorable resolution of several tax-related items in 2006. In addition, gains from the sale or liquidation of U.K. non-electricity delivery businesses are not expected to continue at the same level in 2007 as occurred in 2006.
In March 2007, the U.K. government outlined proposed changes to various U.K. taxes and allowances. This included a reduction in the rate of corporation tax from 30% to 28% effective April 1, 2008, and changes to allowances for PP&E. The proposal is expected to pass into law in July 2007. WPD is currently assessing the impact of the proposed changes, which could result in lower U.K. income taxes for 2007 than currently forecasted by PPL.

·PPL Electric recognized an after-tax charge of $27 million (or $0.07 per share) in the first quarter of 2005 for a loss contingency related to the PJM billing dispute. See Note 11 to the Financial Statements for an update on this matter. PPL cannot be certain of the outcome of this matter or the impact on PPL and its subsidiaries.
·Lower operation and maintenance expenses in the first quarter of 2006 were primarily due to the costs incurred in January 2005, when severe ice storms hit PPL Electric's service territory. The total cost of restoring service to 238,000 customers, excluding capitalized costs and regular payroll expenses, was $16 million (or $0.02 per share).
In August 2005, the PUC issued an order granting PPL Electric's petition for authority to defer and amortize for regulatory accounting and reporting purposes these storm costs subject to certain conditions. As a result of the PUC Order and in accordance with SFAS 71, "Accounting for the Effects of Certain Types of Regulation," in the third quarter of 2005, PPL Electric deferred $12 million (or $0.02 per share) of its previously expensed storm costs. The deferral was based on its assessment of the timing and likelihood of recovering the deferred costs in PPL Electric's next distribution base rate case. At this time, PPL Electric cannot be certain that it will recover the storm costs, nor can it predict whether future incidents of severe weather will cause significant facility damage and service disruptions that would also result in significant costs.

2007 Outlook

PPL projects thatexpects the Pennsylvania Delivery segment willto have flat revenuesearnings in 20062007 compared with 2005 due to favorable weather impacts in 2005 and an increase in2006, with modest load growth being offset by increased operation and maintenance expenses.

In March 2007, PPL Electric filed a request with the PUC to increase distribution rates by approximately $84 million. The PUC's review of the distribution rate request is expected to take about nine months. The proposed distribution rate increase would result in a 2.7% increase over PPL Electric's present rates and would be effective January 1, 2008. PPL Electric cannot predict the outcome of this proceeding.

Refer to PPL's 2006 Form 10-K for information about PPL Electric's plan detailing how it proposes to acquire its PLR electricity supply for non-shopping customers in 2010 after its PLR contract with PPL EnergyPlus expires, as well as the PUC's proposed PLR regulations and policy statement regarding interpretation and implementation of those regulations. Based on current forward market prices, PPL Electric estimated that under its proposed plan customer rates could increase by approximately 30% from 2009 to 2010.

Changes in Domestic Gross Energy Margins By Region

Domestic gross energy margins are generated through PPL's normal hedging (non-trading) activities, as well asnon-trading and trading activities. PPL manages its non-trading energy business on a geographic basis that is aligned with its generation assets. Additionally, beginning in 2006, PPL further segregates non-trading activities into two categories: normal non-trading hedge activity and non-trading economic activity. Non-trading economicEconomic activity represents the net unrealized effect of derivative transactions that are entered into as economic hedges, but do not qualify for hedge accounting, or hedge accounting was not elected, under SFAS 133, "Accounting for Derivative Instruments and Hedging Activities," as amended and interpreted.

Eastern U.S.

Eastern U.S. non-trading margins were higher in the first quarter of 20062007, compared with the same period in 2005,2006, primarily because of an 8.4%a 1.3% increase in PLR sale prices in accordance with the schedule established by the PUC Final Order. Although supply costs were higher due to increased customer demand under the PLR Contract between PPL Electric and PPL EnergyPlus, these costs were offset by higher margins from new supply contracts and higher coal-fired generation volumes. Coal-fired generation volumes were up 4%.

Unrealized gains included in Eastern non-trading margins that resulted from transactions that did not qualify for hedge accounting treatment, or for which hedge accounting was not elected, and from hedge ineffectiveness, were $12 million in the first quarter of 2007, compared with $14 million in 2006.

Western U.S.

Western U.S. non-trading margins were lower in the first quarter of 2007, compared with the same period in 2006, primarily due to lower hydroelectric generation output, which was down 8%. Also contributing to the increase in margins were higher sales prices and lower reliance on higher-cost oil and gas units in 2006. Partially offsetting these improvements were higher wholesale energy purchase prices and higher coal prices, which were up 49%18%, and 18%, respectively.

Non-trading economic activity contributed $12 millionthe sale of PPL's interest in the Griffith plant in 2006. See Note 8 to the quarter due to commodity price movements on forward energy purchase and sale contracts used to hedge wholesale marketing activities.

Northwestern U.S.

Northwestern U.S. non-trading margins were higher in the first quarter of 2006 compared with the same period in 2005, primarily due to higher average sales prices, which were up 18%. Also contributing was a 35% increase in hydroelectric generation output. Partially offsetting these improvements was a 22% increase in average coal prices and a 4% increase in average energy purchase prices.Financial Statements for additional information.

Net Energy Trading

PPL enters into certain energy contracts to take advantage of market opportunities. As a result, PPL may at times create a net open position in its portfolio that meetcould result in significant losses if prices do not move in the criteriamanner or direction anticipated. The margins from these trading activities are reflected in the Statements of Income as "Net energy trading derivatives as defined by EITF Issue 02-3, "Issues Involved in Accounting for Derivative Contracts Held for Trading Purposes and Contracts Involved in Energy Trading and Risk Management Activities.margins." These physical and financial contracts cover trading activity associated with electricity, gas and oil.

The $275 million decreaseincrease in PPL's cash, cash equivalents and short-term investments position was primarily the net result of:

·proceeds of $505 million from the retirement of $225 millionissuance of long-term debt;
·$286 million of cash provided by operating activities;
·a net decreaseincrease in short-term debt of $36$29 million; and
·net proceeds of $26 million (excludingfrom the sale of emission allowances; offset by

·$198 millionthe reclassification of capital expenditures; offset by
·$297$36 million of cash provided by operating activities.related to the Latin American businesses to "Assets held for sale."

Convertible Senior Notes

The terms of PPL Energy Supply's $400 million 2.625% Convertible Senior Notes due 2023 include a market price trigger that permits holders to convert the notes during any fiscal quarter if the closing sale price of PPL's common stock exceeds $29.83 for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter. This market price trigger was met in the first quarter of 2006. Therefore, holdersHolders of the Convertible Senior Notes arewere entitled to convert their notes at any time during the first quarter of 2007 and are also entitled to convert their notes any time during the second quarter of 2006.2007 as a result of the market price trigger being met. When holders elect to convert the Convertible Senior Notes, PPL Energy Supply is required to settle the principal amount in cash and any conversion premium in cash or PPL common stock. During the first quarter of 2007, an insignificant amount of Convertible Senior Notes were presented for conversion and settled with an insignificant amount of cash and PPL common stock. After such conversions, $102 million of Convertible Senior Notes remain outstanding and are eligible for conversion in the second quarter of 2007. PPL and PPL Energy Supply have, and expect to continue to have, access to sufficient liquidity sources to fund any such conversions.

Preference Stock

In April 2006, PPL Electric sold 10 million depositary shares, each representing a quarter interest in a share of PPL Electric's 6.25% Series Preference Stock (Preference Shares), totaling $250 million. In connection with the sale of the depositary shares, PPL Electric issued 2.5 million Preference Shares, with a liquidation preference of $100 per share, to the bank acting as a depositary. PPL Electric used the net proceeds of approximately $245 million from the offering to repurchase $200 million of its common stock held by PPL, and for other general corporate purposes. PPL will use the $200 million received from PPL Electric to fund capital expenditures and for general corporate purposes.

Holders of the depositary shares are entitled to all proportional rights and preferences of the Preference Shares, including dividend, voting, redemption and liquidation rights, exercised through the depositary. The Preference Shares rank senior to PPL Electric's common stock and junior to PPL Electric's outstanding preferred stock, and they have no voting rights, except as provided by law.

Dividends on the Preference Shares will be paid when, as and if declared by the Board of Directors at a fixed annual rate of 6.25%, or $1.5625 per depositary share per year, and are not cumulative. PPL Electric may not pay dividends on, or redeem, purchase or make a liquidation payment with respect to any of its common stock, except in certain circumstances, unless full dividends on the Preference Shares have been paid for the then-current dividend period.

The Preference Shares do not have a stated maturity, and are not subject to sinking fund requirements. However, PPL Electric may, at its option, redeem the Preference Shares in whole or in part from time to time for $100 per share (equivalent to $25 per depositary share), plus any declared and unpaid dividends, on or after April 6, 2011. It is PPL Electric's intention to redeem or repurchase the Preference Shares only from the proceeds of the sale of certain qualifying securities having equity characteristics similar to or greater than the applicable equity characteristics of the Preference Shares. PPL Electric may decide to affirm this intention in the future by making an enforceable covenant in favor of holders of a specific series of its outstanding long-term debt securities.

Credit Facilities

In January 2007, WPD (South West) terminated its £150 million three-year committed credit facility, which was to expire in October 2008. This facility was replaced by a new £150 million five-year committed credit facility at WPDH Limited that expires in January 2012, with the option to extend the expiration date by a maximum of two years.

In March 2006,2007, PPL Energy Supply extended the maturityexpiration date of its 364-day reimbursement agreement, under which it can cause the bank to issue up to $200 million of letters of credit, to March 2007. PPL Energy Supply is currently pursuing extending the maturity of its syndicated credit facilities aggregating $1.4 billion that expire in June 2010 and the maturity of its $500 million syndicated credit facility that expires in December 2010 by one year. PPL Electric is also currently pursuing extending the maturity of its $200 million credit facility that expires in June 2010 by one year. PPL Energy Supply and PPL Electric expect the extensions to be effective in June 2006.

Planned Financing2008.

In March 2006, PPL, PPL Energy Supply and PPL Electric filed a combined omnibus registration statement registering various debt and equity securities. PPL Energy Supply currently plans to issue $300 million of debt in the second quarter of 2006, subject to market conditions.May 2007, PPL Energy Supply expects to useincrease the capacity of its $1.9 billion syndicated credit facility to $3.4 billion and extend the June 2011 expiration date of this facility by one year. The additional capacity is expected to support potential collateral requirements under contracts that PPL Energy Supply anticipates entering into in connection with expanding its wholesale marketing and trading business. In May 2007, PPL Electric also expects to extend the expiration date of its $200 million syndicated credit facility to May 2012.

Financings

In December 2006, Elfec issued $11 million of 6.05% UFV (inflation-adjusted bolivianos) denominated bonds with serial maturities from 2012 through 2014. Of these bonds, $5 million were issued in exchange for existing bonds with maturities in 2007 and 2008. Cash proceeds of $6 million were used in January 2007 to refinance bonds with maturities in 2007. These transactions were reflected in PPL's January 2007 financial statements due to the offeringone-month lag in foreign subsidiary reporting.

In March 2007, PPL Capital Funding issued $500 million of 2007 Series A Junior Subordinated Notes due 2067 (Notes). The Notes are fully and unconditionally guaranteed by PPL as to fundpayment of principal, interest and premium, if any. The Notes mature on March 30, 2067, and are callable at par value beginning March 30, 2017. Prior to such time, the Notes may be redeemed at PPL Capital Funding's option at make-whole redemption prices. The Notes bear interest at 6.70% from the date of issuance up to March 30, 2017. Beginning March 30, 2017, and continuing up to the maturity date, the Notes bear interest at three-month LIBOR plus 2.665%, reset quarterly. PPL Capital Funding may defer interest payments on the Notes, from time to time, on one or more occasions for up to ten consecutive years. Deferred interest payments will accumulate additional interest at a rate equal to the interest rate then applicable to the Notes. During any period in which PPL Capital Funding defers interest payments on the Notes, subject to certain exceptions, neither PPL Capital Funding nor PPL may (i) declare or pay any cash dividend or distribution on its capital stock, (ii) redeem, purchase, acquire or make a liquidation payment with respect to any of its capital stock, or (iii) make any payments on any debt or any guarantee of debt by PPL that is equal or junior in right of payment to the Notes or the related guarantee by PPL.

PPL Capital Funding received $493 million of proceeds, net of a discount and underwriting fees, from the issuance of the Notes. Approximately $280 million of the net proceeds from the sale of the Notes will be used to pay at maturity PPL Capital Funding's 8.375% Medium-Term Notes due June 15, 2007. The remainder of the net proceeds will be used for general corporate purposes, including capital expenditures primarily forrelating to the installation of pollution control equipment by PPL Energy Supply.

In connection with the issuance of the Notes, PPL and PPL Capital Funding entered into a Replacement Capital Covenant, in which PPL and PPL Capital Funding agreed for general corporate purposes.the benefit of holders of a designated series of unsecured long-term indebtedness of PPL or PPL Capital Funding ranking senior to the Notes that (i) PPL Capital Funding will not redeem or purchase the Notes, or otherwise satisfy, discharge or defease the principal amount of the Notes and (ii) neither PPL nor any of its other subsidiaries will purchase the Notes on or before March 30, 2037, except, subject to certain limitations, to the extent that the applicable redemption or repurchase price or principal amount defeased does not exceed a specified amount of proceeds from the sale of qualifying replacement capital securities during the 180-day period prior to the date of that redemption, repurchase or defeasance. The designated series of covered debt to initially benefit from the Replacement Capital Covenant is PPL Capital Funding's 4.33% Notes Exchange Series A Due March 1, 2009.

Early Redemption of Debt

In February 2007, WPD LLP redeemed all of the 8.23% Subordinated Debentures due 2027 that were held by SIUK Capital Trust I. Upon redemption, WPD LLP paid a premium of 4.115%, or approximately $3 million, on the principal amount of $85 million of subordinated debentures. WPD LLP received $3 million when its investment in SIUK Capital Trust I was liquidated in connection with this redemption. Additionally, a payment of $29 million was made to settle related cross-currency swaps.

Proceeds from Anticipated Disposals

Proceeds from the anticipated sales of the Latin American and telecommunications businesses are expected to be used to invest in growth opportunities in PPL's core electricity supply and delivery businesses and/or for the repurchase of securities, including PPL common stock. See Note 8 for additional information.

Rating Agency Decisions

Moody's, S&P and Fitch periodically review the credit ratings on the debt and preferred securities of PPL and its subsidiaries. Based on their respective independent reviews, the rating agencies may make certain ratings revisions or ratings affirmations.

A credit rating reflects an assessment by the rating agency of the credit-worthinesscreditworthiness associated with an issuer and particular securities that it issues. PPL'sThe credit ratings of PPL and its subsidiaries' credit ratingssubsidiaries are based on information provided by PPL and other sources. The ratings of Moody's, S&P and Fitch are not a recommendation to buy, sell or hold any securities of PPL or its subsidiaries. Such ratings may be subject to revisions or withdrawal by thesethe agencies at any time and should be evaluated independently of each other and any other rating that may be assigned to the securities. A downgrade in PPL's or its subsidiaries' credit ratings could result in higher borrowing costs and reduced access to capital markets.

Moody's

In March 2006, Moody'sThe rating agencies took the following actions related to the credit ratings of PPL and its subsidiaries:rated subsidiaries during the first quarter of 2007:

·In connection with PPL -Capital Funding's issuance in March 2007 of the 2007 Series A Junior Subordinated Notes due 2067, Moody's, S&P and Fitch assigned a Baa2 issuer rating;ratings of Baa3, BB+ and BBB- to the junior subordinated debt of PPL Capital Funding.
·Also in March 2007, Fitch affirmed its BBB rating of PPL Capital Funding - upgraded the ratings of its senior unsecured debt and Medium Term Notes to Baa2 from Baa3 and subordinated debt to Baa3 from Ba1; and
·PPL Electric - upgraded the issuer rating to Baa1 from Baa2 and upgraded the ratings of its First Mortgage Bonds and Senior Secured Bonds to A3 from Baa1 and preferred stock to Baa3 from Ba1.Montana's 8.903% Pass Through Certificates due 2020.

Moody's noted that PPL's financial performance improved in 2005 and that it expects PPL's financial performance to continue to improve in 2006. More specifically, Moody's stated that the upgrades were prompted by (i) expectations for higher earnings and cash flow over the next three years, (ii) the generally constructive regulatory situation for PPL Electric, which includes a pass through of generation-based energy costs related to its long-term, full-requirements power supply agreements that enable PPL Electric to meet its obligations as a PLR over the 2006-2009 period, and (iii) moderate expected growth in the volume of energy deliveries, which it indicated supports the expected stability of cash flows from regulated operations until the end of the regulatory transition period in 2009. Moody's acknowledged that the upgrade of PPL Electric takes into consideration the risk that PPL Electric may need to seek large rate increases in 2010, after the expiration of its current supply contracts, if market prices for wholesale power remain at or above current levels. Moody's indicated that the upgrade assumes that regulatory treatment will provide for reasonably timely recovery of increased costs and expenditures.

In March 2006, Moody's also reviewed the credit ratings of PPL Energy Supply and concluded that its ratings remain unchanged.

S&P
In connection with PPL Electric's issuance of Preference Shares in April 2006, S&P affirmed all of PPL Electric's credit ratings.
Fitch

In February 2006, Fitch's Europe, Middle East and Africa group implemented issuer default ratings (IDRs) based on its new IDR methodology. This implementation led to Fitch's assignment of the following IDRs and Fitch's revision of its ratings on the following securities currently outstanding at WPD and its affiliates:

·WPDH Limited IDR of BBB- and senior unsecured rating to BBB from BBB-;
·WPD LLP IDR of BBB, senior unsecured rating to BBB+ from BBB and preferred stock rating to BBB from BBB-; and
·WPD (South Wales) and WPD (South West) IDR of BBB+ and senior unsecured debt rating to A- from BBB+.

Fitch's outlook for WPD and its affiliates remains stable.

Market Risk

Commodity Price Risk (Non-trading)

PPL's non-trading commodity derivative contracts mature at various times through 2012.2017. PPL segregates its non-trading activities as either hedge or economic. Transactions that are accounted for as hedge activity qualify for special hedge accounting treatment under SFAS 133, "Accounting133. The majority of PPL's energy transactions qualify for Derivative Instruments and Hedging Activities," as amended and interpreted.accrual or hedge accounting. The non-trading economic category includes transactions that address a specific risk, but are not eligible for hedge accounting or hedge accounting is not elected. Included in the non-trading economic category are certain load-following energy obligations and related supply contracts, financial transmission rights,FTRs, crude oil swaps to hedge rail transportation charges and hedges of synthetic fuel tax credits. Although they do not receive hedge accounting treatment, these contracts are considered non-trading. The fair value of thesethe non-trading economic contracts that do not qualify for accrual or hedge accounting treatment as of March 31, 2006,2007, including net premiums on related options, was $73$88 million. The following chart sets forth PPL's net fair market value of theall non-trading commodity derivative contracts.

Beginning in January 2006, PPL instituted a program to hedge its exposures to changes in market prices of certain metals necessary for the scrubbers PPL is installing at the Brunner Island and Montour generating plants. These contracts, which qualify for cash flow hedge treatment, were designated as hedges in March 2006 and their fair values are included in the table above.

The following chart segregates estimated fair values of PPL's non-trading commodity derivative contracts at March 31, 2006,2007, based on whether the fair values are determined by quoted market prices or other more subjective means.

The "Prices actively quoted" category includes the fair value of exchange-traded natural gas futures contracts quoted on the NYMEX. The NYMEX, which has currently quoted prices through 2011.

The "Prices provided by other external sources" category includes PPL's forward positions and options in natural gas and powerelectricity and natural gas basis swaps at points for which over-the-counter (OTC) broker quotes are available. The fair value of electricity positions recorded above use the midpoint of the bid/ask spreads obtained through OTC brokers. On average, OTC quotes for forwards and swaps of natural gas and power extend one and two years into the future.

The "Prices based on models and other valuation methods" category includes the value of transactions for which an internally developed price curve was constructed as a result of the long-dated nature of the transaction or the illiquidity of the market point, or the value of options not quoted by an exchange or OTC broker. This category reflectsincludes the fair value of transactions completed in auction markets, where contract prices represent the market value for load-following bundled energy prices delivered at specific, illiquid delivery points. The transaction prices associated with the contracts did not equal the wholesale bilateral market prices at inception (Day 1). However, EITF 02-3 "Issues Involved in Accounting for Derivative Contracts Held for Trading Purposes and Contracts Involved in Energy Trading and Risk Management Activities," does not generally permit Day 1 gains and losses to be recognized unless the fair value is derived principally from observable market inputs. Therefore, PPL recorded a reserve for the modeled Day 1 gain, which is netted against the above fair values.

Because of PPL's efforts to hedge the value of the energy from its generation assets, PPL sells electricity, capacity and related services and buys fuel on a forward basis, resulting in open contractual positions. If PPL is unable to deliver firm capacity and energy or to accept the delivery of fuel under its agreements, under certain circumstances it could be required to pay damages. These damages would be based on the difference between the market price and the contract price of the commodity. Depending on price volatility in the wholesale energy markets, such damages could be significant. Extreme weather conditions, unplanned power plant outages, transmission disruptions, non-performance by counterparties (or their own counterparties) with which it has energy contracts and other factors could affect PPL's ability to meet its obligations, or cause significant increases in the market price of replacement energy. Although PPL attempts to mitigate these risks, there can be no assurance that it will be able to fully meet its firm obligations, that it will not be required to pay damages for failure to perform, or that it will not experience counterparty non-performance in the future.

As of March 31, 2006,2007, PPL estimated that a 10% adverse movement in market prices across all geographic areas and time periods excluding the effect of any commodity price correlations, would have decreased the value of the commodity contracts in its non-trading portfolio by approximately $373 million, compared to $263 million.million as of March 31, 2006. For purposes of this calculation, an increase in the market price for electricity is considered an adverse movement because PPL's electricity portfolio is generally in a net sales position, and the decrease in the market price for fuel is considered an adverse movement because PPL's commodity fuels portfolio is generally in a net purchase position. PPL enters into thesethose commodity contracts to reduce the market risk inherent in the generation of electricity.

Starting in 2007, PPL elected to use an alternative method for disclosing quantitative information about certain market risk sensitive instruments. This method utilizes a VaR model to measure commodity price risk in its non-trading and trading portfolios. This approach is consistent with how PPL's Risk Manager assesses the market risk of its commodity business. VaR is a statistical model that attempts to predict risk of loss, under normal market conditions, based on historical market price volatility. PPL calculates VaR using a Monte Carlo simulation technique, which uses historical data from the past 12 month period. The VaR is the estimated nominal loss of earnings based on a one-day holding period at a 95% confidence interval. As of March 31, 2007, the VaR for PPL's non-trading portfolio was $16 million. This excludes the activity for PPL's synthetic fuel tax credit hedges. Additional information regarding these hedges can be found in the "Synthetic Fuel Tax Credit Risk" section below.

As of March 31, 2007, PPL estimated that a 10% adverse movement in market prices across all geographic areas and time periods would have decreased the value of the commodity contracts in its trading portfolio by $35 million, compared to $20 million as of March 31, 2006.

As of March 31, 2007, the VaR for PPL Energy Supply's trading portfolio was $4 million. This excludes the activity for PPL Energy Supply's synthetic fuel tax credit hedges. Additional information regarding these hedges can be found in the "Synthetic Fuel Tax Credit Risk" section below.

Synthetic Fuel Tax Credit Risk

At this time, PPL expects that the high level and the volatility of crude oil prices will reduce the amount of synthetic fuel tax credits that PPL receives through its synthetic fuel production. The tax credits are reduced if the annual average wellhead price of domestic crude oil falls within a phase-out range. The tax credits are eliminated if this reference price exceeds the phase-out range. See "Regulatory Issues - IRS Synthetic Fuels Tax Credits" in Note 10 to the Financial Statements for more information regarding the phase-out of the tax credits.

PPL implemented a risk management strategy to hedge a portion of the variability of cash flows associated with its 2006 and 2007 synthetic fuel tax credits by hedging the risk that the 2006 and 2007 annual average wellhead price for domestic crude oil will be within the phase-out range.

PPL has net purchased options for 2007 that are expected to mitigate PPL's tax credit phase-out risk due to an increase of the average wellhead price in 2007. These positions did not qualify for hedge accounting treatment. The mark-to-market value of these positions at March 31, 2007, was a gain of $29 million.
As of March 31, 2007, PPL estimated that a 10% adverse movement in market prices of crude oil would have decreased the value of the synthetic fuel hedges by $26 million. For purposes of this calculation, a decrease in the market price for crude oil is considered an adverse movement.

Commodity Price Risk Summary

In accordance with its marketing strategy, PPL doeselects not completelyto fully hedge its generation output or fuel requirements. PPL estimates that for its entire portfolio, including all generation, emissions and physical and financial energy positions, a 10% adverse change in power prices across all geographic zones and time periods would decrease expected 20062007 gross margins by $14$7 million. Similarly, aA 10% adverse movement in all fossil fuel prices would decrease 2006not have a material effect on expected 2007 gross margins by $31 million.

The data in the above tables includes the activity for PPL's synthetic fuel tax credit hedges. Additional information regarding these hedges can be found in the "Synthetic Fuel Tax Credit Risk" section below.

Commodity Price Risk (Trading)

PPL also executes energy contracts to take advantage of market opportunities. As a result, PPL may at times create a net open position in its portfolio that could result in significant losses if prices do not move in the manner or direction anticipated. The margins from these trading activities are shown in the Statement of Income as "Net energy trading margins."

As of March 31, 2006, PPL estimated that a 10% adverse movement in market prices across all geographic areas and time periods, excluding the effect of any commodity price correlations, would have decreased the value of the commodity contracts in its trading portfolio by $20 million.

Interest Rate Risk

PPL and its subsidiaries have issued debt to finance their operations.operations, which exposes them to interest rate risk. PPL utilizes various financial derivative products to adjust the mix of fixed and floating interest rates in its debt portfolio, adjust the duration of its debt portfolio and lock in treasury rates (and interest rate spreads over treasuries) in anticipation of future financing, when appropriate. Risk limits under the risk management program are designed to balance risk exposure to volatility in interest expense and changes in the fair value of PPL's debt portfolio due to changes in the absolute level of interest rates.

At March 31, 2006,2007, PPL's potential annual exposure to increased interest expense, based on a 10% increase in interest rates, was $7$10 million.

PPL is also exposed to changes in the fair value of its domestic and international debt portfolios. At March 31, 2006,2007, PPL estimated that its potential exposure to a change in the fair value of its debt portfolio, through a 10% adverse movement in interest rates, was $189$342 million.

PPL utilizes various risk management instruments to reduce its exposure to the expected future cash flow variability of its debt instruments. These risks include exposure to adverse interest rate movements for outstanding variable rate debt and for future anticipated financing. While PPL is exposed to changes in the fair value of these instruments, any changes in the fair value of these instruments are recorded in equity and then reclassified into earnings in the same period during which the item being hedged affects earnings. At March 31, 2006,2007, the market value of these instruments, representing the amount PPL would receivepay upon their termination, was $39$2 million. At March 31, 2006,2007, PPL estimated that its potential exposure to a change in the fair value of these instruments, through a 10% adverse movement in the hedged exposure, was $46$10 million.

PPL also utilizes various risk management instruments to adjust the mix of fixed and floating interest rates in its debt portfolio. While PPL is exposed to changes in the fair value of these instruments, any change in market value is recorded with an equal and offsetting change in the value of the debt being hedged. At March 31, 2006,2007, PPL estimated that its potential additional exposure to a change in the fair value of these instruments, through a 10% adverse movement in interest rates, was $12$18 million.

WPDH Limited holds a net position in cross-currency swaps totaling $702 million, to hedge the interest payments and principal of its U.S. dollar-denominated bonds with maturity dates ranging from December 2007 to December 2028. The estimated value of this position at March 31, 2007, being the amount PPL would pay to terminate it, including accrued interest, was $170 million. At March 31, 2007, PPL estimated that its potential additional exposure to a change in the market value of these instruments, through a 10% adverse movement in foreign currency exchange rates and interest rates, was $132 million.

Foreign Currency Risk

PPL is exposed to foreign currency risk, primarily through investments in affiliates in the U.K. and Latin America. In addition, PPL may make purchases of equipment in currencies other than U.S. dollars.

PPL has adopted a foreign currency risk management program designed to hedge certain foreign currency exposures, including firm commitments, recognized assets or liabilities and net investments. In addition, PPL enters into financial instruments to protect against foreign currency translation risk.risk of expected earnings.

To protect 2006economically hedge 2007 expected income in Chilean pesos, PPL entered into an average rate forwardforwards for 812.4 billion Chilean pesos. The settlement date of this forwardthese forwards is November 2006.2007. At March 31, 2006,2007, the market value of this position,these positions, representing the amount PPL would receive upon itstheir termination, was insignificant.not significant. PPL estimated that its potential additional exposure to a change in the market value of this instrument,these instruments, through a 10% adverse movement in foreign currency exchange rates, was $1 million at March 31, 2006.2007.

To protect 2006economically hedge 2007 expected income denominated in British pounds sterling, PPL entered into a combination of average rate forwards and average rate options for £88£82.9 million. These forwards and options terminate in November 2006.have termination dates ranging from April 2007 to December 2007. At March 31, 2006,2007, the market value of these positions, representing the amount PPL would receivepay upon their termination, was $2$1 million. PPL estimated that its potential additional exposure to a change in the market value of these instruments, through a 10% adverse movement in foreign currency exchange rates, was $4$10 million at March 31, 2006.2007.

WPDH Limited holds a net position in cross-currency swaps totaling $1.1PPL executed forward sale contracts for 175 billion Chilean pesos. Of these forward sale contracts, 161 billion Chilean pesos are to hedge PPL's net investment in Emel. The settlement date of these forwards is December 2007. At March 31, 2007, the interest payments andmarket value of its U.S. dollar-denominated bonds with maturity dates ranging from December 2006 to December 2028. The estimated value of this position at March 31, 2006, beingthese positions, representing the amount PPL would pay to terminate it, including accrued interest,receive upon their termination, was $178$1 million.

Nuclear Decommissioning Trust Funds - Securities Price Risk

In connection with certain NRC requirements, PPL Susquehanna maintains trust funds to fund certain costs of decommissioning the Susquehanna nuclear station. As of March 31, 2006,2007, these funds were invested primarily in domestic equity securities and fixed-rate, fixed-income securities and are reflected at fair value on PPL's Balance Sheet. The mix of securities is designed to provide returns sufficient to be used to fund Susquehanna's decommissioning and to compensate for inflationary increases in decommissioning costs. However, the equity securities included in the trusts are exposed to price fluctuation in equity markets, and the values of fixed-rate, fixed-income securities in the trusts are exposed to changes in interest rates. PPL Susquehanna actively monitors the investment performance and periodically reviews asset allocation in accordance with its nuclear decommissioning trust policy statement. At March 31, 2006,2007, a hypothetical 10% increase in interest rates and a 10% decrease in equity prices would have resulted in an estimated $35$38 million reduction in the fair value of the trust assets. See the "Asset Retirement Obligations and Nuclear Decommissioning" Note 21 in the 2005PPL's 2006 Form 10-K for more information regarding the nuclear decommissioning trust funds.

Synthetic Fuel Tax Credit Risk

At this time, PPL expects that the current high level and the volatility of crude oil prices will reduce the amount of synthetic fuel tax credits that PPL receives through its synthetic fuel production. The tax credits are reduced if the annual average wellhead price of domestic crude oil falls within a phase-out range. The tax credits are eliminated if this reference price exceeds the phase-out range. See "Regulatory Issues - IRS Synthetic Fuels Tax Credits" in Note 11 to the Financial Statements for more information regarding the phase-out of the tax credits and shutdown of synfuel projects.

PPL implemented a risk management strategy to hedge a portion of the variability of cash flows associated with its 2006 and 2007 synthetic fuel tax credits by hedging the risk that the 2006 and 2007 annual average wellhead price for domestic crude oil will be within the phase-out range.

PPL purchased options in 2005 to mitigate some of the reductions in synthetic fuel tax credits if the annual average wellhead price for 2006 and 2007 falls within the applicable phase-out range. These positions did not qualify for hedge accounting treatment. The mark-to-market value of these positions at March 31, 2006, was a gain of $33 million. Of this total, $23 million was recorded during the three months ended March 31, 2006, and is reflected in "Energy-related businesses" revenues on the Statement of Income.

As of March 31, 2006, PPL estimated that a 10% adverse movement in market prices of crude oil would have decreased the value of the synthetic fuel hedges to a nominal amount. For purposes of this calculation, a decrease in the market price for crude oil is considered an adverse movement.

Related Party Transactions

PPL is not aware of any material ownership interests or operating responsibility by senior management of PPL, PPL Energy Supply or PPL Electric in outside partnerships, including leasing transactions with variable interest entities, or other entities doing business with PPL.

For additional information on related party transactions, see Note 1211 to the Financial Statements.

Acquisitions, Development and Divestitures

From time to time, PPL and its subsidiaries are involved in negotiations with third parties regarding acquisitions and dispositions of businesses and assets, joint ventures and development projects, which may or may not result in definitive agreements. Management is in the process of reviewing strategic alternatives for certain of its gas-fired generation assets.  Any such transactions may impact future financial results. See Note 8 to the Financial Statements for information regarding such recent transactions.

PPL is currently planning incremental capacity increases of 270355 MW at several existing domestic generating facilities. Offsetting this increase is an expected 30 MW reduction in generation capability at each of the Brunner Island and Montour plants, due to the estimated increases in station service usage during the scrubber operation. See Note 10 to the Financial Statements for additional information, as well as information regarding the planned shut down of two 150 MW generating units at PPL Martins Creek in September 2007.

PPL is continuously reexamining development projects based on market conditions and other factors to determine whether to proceed with these projects, sell them, cancel them, expand them, execute tolling agreements or pursue other opportunities.

Environmental Matters

See Note 1110 to the Financial Statements for a discussion of environmental matters.

New Accounting Standards

See Note 1817 to the Financial Statements for a discussion of new accounting standards recently adopted or pending adoption.

Application of Critical Accounting Policies

PPL's financial condition and results of operations are impacted by the methods, assumptions and estimates used in the application of critical accounting policies. The following accounting policies are particularly important to the financial condition or results of operations of PPL, and require estimates or other judgments of matters inherently uncertain: price risk management, pension and other postretirement benefits, asset impairment, leasing, loss accruals and asset retirement obligations.

See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations," in PPL's 20052006 Form 10-K for a discussion of each critical accounting policy. PPL's senior management has reviewed these critical accounting policies, and the estimates and assumptions regarding them, with its Audit Committee. In addition, PPL's senior management reviewed the Form 10-K disclosures regarding the application of these critical accounting policies with the Audit Committee.

In June 2006, the FASB issued FIN 48, "Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109." In May 2007, the FASB amended this guidance by issuing FSP FIN 48-1, "Definition of Settlement in FASB Interpretation No. 48." PPL and its subsidiaries adopted FIN 48, as amended, effective January 1, 2007. The adoption of FIN 48 alters the methodology PPL previously used to account for income tax uncertainties. Effective with the adoption of FIN 48, uncertain tax positions are no longer considered to be contingencies assessed in accordance with SFAS 5, "Accounting for Contingencies." The following is an update to the "Income Tax Uncertainties" section of the "Loss Accruals" critical accounting policy disclosed in PPL's 2006 Form 10-K, which reflects the adoption of FIN 48.
Similar to SFAS 5, FIN 48 continues to require significant management judgment in determining the amount of benefit to be recognized in relation to an uncertain tax position. FIN 48 requires PPL to evaluate its tax positions following a two-step process. The first step requires an entity to determine whether, based on the technical merits supporting a particular tax position, it is more likely than not (greater than a 50 percent chance) that the tax position will be sustained. This determination assumes that the relevant taxing authority will examine the tax position and is aware of all the relevant facts surrounding the tax position. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The measurement of the benefit equals the largest amount of benefit that has a likelihood of realization, upon settlement, that exceeds 50 percent. PPL's management considers a number of factors in assessing the benefit to be recognized, including negotiation of a settlement.

On a quarterly basis, PPL reassesses its uncertain tax positions by considering information known at the reporting date. Based on management's assessment of new information, PPL may subsequently recognize a tax benefit for a previously unrecognized tax position, derecognize a previously recognized tax position, or remeasure the benefit of a previously recognized tax position.

The balance sheet classification of unrecognized tax benefits also requires significant management judgment. FIN 48 requires an entity to classify unrecognized tax benefits as current, to the extent management expects to settle an uncertain tax position, by paying cash, within one year of the reporting date.

Significant management judgment is also required in developing valuation allowances for deferred tax assets. Valuation allowances are initially recorded and reevaluated each reporting period by assessing the likelihood of the ultimate realization of a deferred tax asset. Management considers a number of factors in assessing the realization of a deferred tax asset, including forecasts of future taxable income and available tax planning strategies. Any tax planning strategy utilized in this assessment must meet the recognition and measurement criteria of FIN 48. See Note 5 to the Financial Statements for the disclosures required by FIN 48.

2007 Outlook

PPL Energy Supply projects significantly higher earnings in its Supply business segment in 2007 compared with 2006. Based on current forward energy prices and hedges already in place, PPL Energy Supply is projecting higher energy margins for its Supply segment in 2006 comparedthe balance of 2007, driven primarily by the replacement of expiring supply obligations with 2005. This increase is primarily driven by an 8.4% increase in PLR sale prices. Higher generation output and higher-pricedhigher-margin wholesale energy contracts, that replace expiringsuch as the contract with NorthWestern in Montana, as well as new full-requirements contracts also are expected to improve energy margins. These benefits are expected to be partially offset by increased fuel and fuel transportation expenses, higher operation and maintenance expenses and reduced earnings from synfuel projects.in the Mid-Atlantic region.

See "Regulatory Issues - IRS Synthetic Fuels Tax Credits" in Note 11 to the Financial Statements for a discussion of the tax credits thatWhile PPL Energy Supply has earnedexpects improved baseload power plant performance in connection with its synfuel projects2007, this performance will be offset by the retirement in September of two small coal-fired units in Pennsylvania and by planned outages, including the impact of higher oil prices on future tax credits. In early April 2006,Susquehanna Unit 1 outage, which is expected to conclude the control rod friction issues that have affected plant operations over the past several years. PPL Energy Supply suspended operations at onebelieves these planned outages will improve the overall long-term reliability of its two synfuel projects based upon increased oil prices and the potential phase-out of these tax credits under existing tax rules. For these same reasons, PPL Energy Supply currently expects to suspend operations at its other synfuel project in mid-2006.
PPL Energy Supply had projected an earnings contribution from the combination of synfuel projects and synthetic fuel-related hedges of $39 million in 2006.  Based upon projected production levels reflecting the suspension of PPL Energy Supply's synthetic fuel operations as discussed above and assuming the continued suspension for the remainder of 2006, PPL Energy Supply's earnings from the combination of synfuel projects and synthetic fuel-related hedges would be $19 million in 2006.

In addition to producing synthetic fuel,generation fleet. PPL Energy Supply also purchases synthetic fuel from unaffiliated third parties, at prices below the market price of coal, for use at its coal-fired power plants. PPL Energy Supply estimates that if these third parties had discontinued their synthetic fuel operationsexpects a modest increase in fuel-related expenses and sales to PPL Energy Supply at the end of April 2006 due to the impact of projected oil prices, the company would incur additional fuel costs of $16 million ($9 million after tax) for the remainder of 2006.

There currently are legislative proposals pending in the U.S. Congress that could affect the potential phase-out of the synthetic fuel tax credits for 2006increased operation and 2007. At this time, PPL Energy Supply cannot predict whether any such legislation will be enacted or the impact of any such legislation on its synthetic fuel operations or tax credits in 2006 or 2007.

The net carrying value of the property, plant and equipment and intangible assets associated with PPL Energy Supply's two synfuel projects was $12 million at March 31, 2006. As of March 31, 2006, the estimated phase-out of synthetic fuel tax credits, based on forward oil prices as of that date, did not result in these assets being impaired. However, these estimates can change significantly due to the volatility in oil prices as well as the potential impact of pending legislation, which could result in an impairment of the synfuel project assets that would otherwise be depreciated or amortized in 2006 and 2007. PPL Energy Supply will continue to assess the status of its synfuel projects as changes in oil prices, legislation and other factors occur.maintenance expenses.

International Delivery Segment

The International Delivery segment includes operations of the international energy businesses of PPL Global that are primarily focused on the distribution of electricity. Substantially all of PPL Global's international businesses are located in the U.K., Chile, El Salvador and Bolivia.

The International Delivery segment results in the first quarter of 2007 and 2006 reflect the reclassification of Latin American revenues and expenses to "(Loss) Income from Discontinued Operations." See Note 8 to the Financial Statements for further discussion.

2007 Outlook
PPL Energy Supply projects that the earnings from its International Delivery business segment will experience increased operation and maintenance expensesto decline in 20062007 compared with 2005, primarily resulting from2006. Higher delivery margins in the U.K., due to higher pension costs at WPD,unit prices, are expected to be more than offset by increased operating expenses and higher U.S. income taxes and a potential unfavorable change in foreign currency exchange ratesthe U.K. in 2007, due to the favorable resolution of several tax-related items in 2006. In addition, gains from the sale or liquidation of U.K. non-electricity delivery businesses are not expected to continue at the same level in 2007 as occurred in 2006.
In March 2007, the U.K. government outlined proposed changes to various U.K. taxes and allowances. This included a reduction in the rate of corporation tax from 30% to 28% effective April 1, 2008, and changes to allowances for PP&E. The proposal is expected to pass into law in July 2007. WPD is currently assessing the impact of the proposed changes, which could result in lower U.K. income taxes for 2007 than currently forecasted by PPL Energy Supply.

Changes in Domestic Gross Energy Margins By Region

Domestic gross energy margins are generated through PPL Energy Supply's normal hedging (non-trading) activities, as well asnon-trading and trading activities. PPL Energy Supply manages its non-trading energy business on a geographic basis that is aligned with its generation assets. Additionally, beginning in 2006, PPL Energy Supply further segregates non-trading activities into two categories: normal non-trading hedge activity and non-trading economic activity. Non-trading economicEconomic activity represents the net unrealized effect of derivative transactions that are entered into as economic hedges, but do not qualify for hedge accounting, or hedge accounting was not elected, under SFAS 133, "Accounting for Derivative Instruments and Hedging Activities," as amended and interpreted.

Eastern U.S.

Eastern U.S. non-trading margins were higher in the first quarter of 20062007, compared with the same period in 2005,2006, primarily because of an 8.4%a 1.3% increase in PLR sale prices in accordance with the schedule established by the PUC Final Order. Although supply costs were higher due to increased customer demand under the PLR Contract between PPL Electric and PPL EnergyPlus, these costs were offset by higher margins from new supply contracts and higher coal-fired generation volumes. Coal-fired generation volumes were up 4%.

Unrealized gains included in Eastern non-trading margins that resulted from transactions that did not qualify for hedge accounting treatment, or for which hedge accounting was not elected, and from hedge ineffectiveness, were $12 million in the first quarter of 2007, compared with $14 million in 2006.

Western U.S.

Western U.S. non-trading margins were lower in the first quarter of 2007, compared with the same period in 2006, primarily due to lower hydroelectric generation output, which was down 8%. Also contributing to the increase in margins were higher sales prices and lower reliance on higher-cost oil and gas units in 2006. Partially offsetting these improvements were higher wholesale energy purchase prices and higher coal prices, which were up 49%18%, and 18%, respectively.

Non-trading economic activity contributed $12 millionthe sale of PPL's interest in the Griffith plant in 2006. See Note 8 to the quarter due to commodity price movements on forward energy purchase and sale contracts used to hedge wholesale marketing activities.

Northwestern U.S.

Northwestern U.S. non-trading margins were higher in the first quarter of 2006 compared with the same period in 2005, primarily due to higher average sales prices, which were up 18%. Also contributing was a 35% increase in hydroelectric generation output. Partially offsetting these improvements was a 22% increase in average coal prices and a 4% increase in average energy purchase prices.Financial Statements for additional information.

Net Energy Trading

PPL Energy Supply enters into certain energy contracts to take advantage of market opportunities. As a result, PPL may at times create a net open position in its portfolio that meetcould result in significant losses if prices do not move in the criteriamanner or direction anticipated. The margins from these trading activities are reflected in the Statements of Income as "Net energy trading derivatives as defined by EITF Issue 02-3, "Issues Involved in Accounting for Derivative Contracts Held for Trading Purposes and Contracts Involved in Energy Trading and Risk Management Activities.margins." These physical and financial contracts cover trading activity associated with electricity, gas and oil.

Energy-related Businesses

Energy-related businesses contributed $19$27 million moreless to operating income for the three months ended March 31, 2006,2007, compared with the same period in 2005.2006. The increasedecrease was primarily attributable to a $20$31 million higherimpairment of telecommunication assets (see Note 8), partially offset by $3 million of lower pre-tax contributionlosses from synfuel projects. This reflects $5 million of lower operating losses due to lower production levels; partially offset by a $23$2 million netlower unrealized gain on options purchased to hedge a portion of the risk associated with the phase-out of the synthetic fuel tax credits for 2006 and 2007, offset by $3 million of additional operating expenses due to higher production levels.credits.

Financial Condition

Liquidity and Capital Resources

At March 31, 2006, PPL Energy Supply had $132 million ofthe following cash and cash equivalents and $44 million of short-term debt (including a note payable to an affiliate). At December 31, 2005, PPL Energy Supply had $260 million of cash, cash equivalents and short-term investments and $180as of the dates noted below:

The $253 million of short-term debt (including a note payable to an affiliate). The $128 million decreaseincrease in PPL Energy Supply's cash, cash equivalents and short-term investments position was primarily the net result of:

·$500 million of contributions from Member;
·$223 million of cash provided by operating activities; and
·net proceeds of $26 million from the sale of emission allowances; offset by
·$270 million of capital expenditures;
·the retirement of $121 million of long-term debt (which includes a net decrease in short-term debtpayment of $137$29 million (excluding a $1 million impact of currency translation adjustments)to settle related cross-currency swaps);
·distributions to Member of $58$72 million; and
·$147 millionthe reclassification of capital expenditures; offset by
·$225$36 million of cash provided by operating activities.related to the Latin American businesses to "Assets held for sale."

Convertible Senior Notes

The terms of PPL Energy Supply's $400 million 2.625% Convertible Senior Notes due 2023 include a market price trigger that permits holders to convert the notes during any fiscal quarter if the closing sale price of PPL's common stock exceeds $29.83 for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter. This market price trigger was met in the first quarter of 2006. Therefore, holdersHolders of the Convertible Senior Notes arewere entitled to convert their notes at any time during the first quarter of 2007 and are also entitled to convert their notes any time during the second quarter of 2006.2007 as a result of the market price trigger being met. When holders elect to convert the Convertible Senior Notes, PPL Energy Supply is required to settle the principal amount in cash and any conversion premium in cash or PPL common stock. During the first quarter of 2007, an insignificant amount of Convertible Senior Notes were presented for conversion and settled with an insignificant amount of cash and PPL common stock. After such conversions, $102 million of Convertible Senior Notes remain outstanding and are eligible for conversion in the second quarter of 2007. PPL and PPL Energy Supply have, and expect to continue to have, sufficient liquidity sources to fund any such conversions.

Credit Facilities

In January 2007, WPD (South West) terminated its £150 million three-year committed credit facility, which was to expire in October 2008. This facility was replaced by a new £150 million five-year committed credit facility at WPDH Limited that expires in January 2012, with the option to extend the expiration date by a maximum of two years.

In March 2006,2007, PPL Energy Supply extended the maturityexpiration date of its 364-day reimbursement agreement, under which it can cause the bank to issue up to $200 million of letters of credit, to March 2007. PPL Energy Supply is currently pursuing extending the maturity of its syndicated credit facilities aggregating $1.4 billion that expire in June 2010 and the maturity of its $500 million syndicated credit facility that expires in December 2010 by one year. PPL Energy Supply expects the extensions to be effective in June 2006.

Planned Financing2008.

In March 2006, PPL, PPL Energy Supply and PPL Electric filed a combined omnibus registration statement registering various debt and equity securities. PPL Energy Supply currently plans to issue $300 million of debt in the second quarter of 2006, subject to market conditions.May 2007, PPL Energy Supply expects to useincrease the capacity of its $1.9 billion syndicated credit facility to $3.4 billion and extend the June 2011 expiration date of this facility by one year. The additional capacity is expected to support potential collateral requirements under contracts that PPL Energy Supply anticipates entering into in connection with expanding its wholesale marketing and trading business.

Financings

In December 2006, Elfec issued $11 million of 6.05% UFV (inflation-adjusted bolivianos) denominated bonds with serial maturities from 2012 through 2014. Of these bonds, $5 million were issued in exchange for existing bonds with maturities in 2007 and 2008. Cash proceeds of $6 million were used in January 2007 to refinance bonds with maturities in 2007. These transactions were reflected in PPL's January 2007 financial statements due to the offeringone-month lag in foreign subsidiary reporting.

Early Redemption of Debt

In February 2007, WPD LLP redeemed all of the 8.23% Subordinated Debentures due 2027 that were held by SIUK Capital Trust I. Upon redemption, WPD LLP paid a premium of 4.115%, or approximately $3 million, on the principal amount of $85 million of subordinated debentures. WPD LLP received $3 million when its investment in SIUK Capital Trust I was liquidated in connection with this redemption. Additionally, a payment of $29 million was made to fund capital expenditures, primarilysettle related cross-currency swaps.

Proceeds from Anticipated Disposals

Proceeds from the anticipated sales of the Latin American and telecommunications businesses are expected to be used to invest in growth opportunities in PPL's core electricity supply and delivery businesses and/or for pollution control equipment, andthe repurchase of securities, including PPL common stock. See Note 8 for general corporate purposes.additional information.

Market Risk

Commodity Price Risk (Non-Trading)(Non-trading)

PPL Energy Supply's non-trading commodity derivative contracts mature at various times through 2012.2017. PPL Energy Supply segregates its non-trading activities as either hedge or economic. Transactions that are accounted for as hedge activity qualify for special hedge accounting treatment under SFAS 133, "Accounting133. The majority of PPL Energy Supply's energy transactions qualify for Derivative Instruments and Hedging Activities," as amended and interpreted.accrual or hedge accounting. The non-trading economic category includes transactions that address a specific risk, but are not eligible for hedge accounting or hedge accounting is not elected. Included in the non-trading economic category are certain load-following energy obligations and related supply contracts, financial transmission rights,FTRs, crude oil swaps to hedge rail transportation charges and hedges of synthetic fuel tax credits. Although they do not receive hedge accounting treatment, these contracts are considered non-trading. The fair value of thesethe non-trading economic contracts that do not qualify for accrual or hedge accounting treatment as of March 31, 2006,2007, including net premiums on related options, was $73$88 million.

Beginning in January 2006, PPL Energy Supply instituted a program to hedge its exposures to changes in market prices of certain metals necessary for the scrubbers PPL Energy Supply is installing at the Brunner Island and Montour generating plants. These contracts, which qualify for cash flow hedge treatment, were designated as hedges in March 2006 and their fair values are included in the table above.

The "Prices actively quoted" category includes the fair value of exchange-traded natural gas futures contracts quoted on the NYMEX. The NYMEX, which has currently quoted prices through 2011.

The "Prices provided by other external sources" category includes PPL Energy Supply's forward positions and options in natural gas and powerelectricity and natural gas basis swaps at points for which over-the-counter (OTC) broker quotes are available. The fair value of electricity positions recorded above use the midpoint of the bid/ask spreads obtained through OTC brokers. On average, OTC quotes for forwards and swaps of natural gas and power extend one and two years into the future.

The "Prices based on models and other valuation methods" category includes the value of transactions for which an internally developed price curve was constructed as a result of the long-dated nature of the transaction or the illiquidity of the market point, or the value of options not quoted by an exchange or OTC broker. This category reflectsincludes the fair value of transactions completed in auction markets, where contract prices represent the market value for load-following bundled energy prices delivered at specific, illiquid delivery points. The transaction prices associated with the contracts did not equal the wholesale bilateral market prices at inception (Day 1). However, EITF 02-3 "Issues Involved in Accounting for Derivative Contracts Held for Trading Purposes and Contracts Involved in Energy Trading and Risk Management Activities," does not generally permit Day 1 gains and losses to be recognized unless the fair value is derived principally from observable market inputs. Therefore, PPL Energy Supply recorded a reserve for the modeled Day 1 gain, which is netted against the above fair values.

Because of PPL Energy Supply's efforts to hedge the value of the energy from its generation assets, PPL Energy Supply sells electricity, capacity and related services and buys fuel on a forward basis, resulting in open contractual positions. If PPL Energy Supply were unable to deliver firm capacity and energy or to accept the delivery of fuel under its agreements, under certain circumstances it could be required to pay damages. These damages would be based on the difference between the market price and the contract price of the commodity. Depending on price volatility in the wholesale energy markets, such damages could be significant. Extreme weather conditions, unplanned power plant outages, transmission disruptions, non-performance by counterparties (or their own counterparties) with which it has energy contracts and other factors could affect PPL Energy Supply's ability to meet its obligations, or cause significant increases in the market price of replacement energy. Although PPL Energy Supply attempts to mitigate these risks, there can be no assurance that it will be able to fully meet its firm obligations, that it will not be required to pay damages for failure to perform, or that it will not experience counterparty non-performance in the future.

As of March 31, 2006,2007, PPL Energy Supply estimated that a 10% adverse movement in market prices across all geographic areas and time periods excluding the effect of any commodity price correlations, would have decreased the value of the commodity contracts in its non-trading portfolio by approximately $373 million, compared to $263 million.million as of March 31, 2006. For purposes of this calculation, an increase in the market price for electricity is considered an adverse movement because PPL Energy Supply's electricity portfolio is generally in a net sales position, and the decrease in the market price for fuel is considered an adverse movement because PPL Energy Supply's commodity fuels portfolio is generally in a net purchase position. PPL Energy Supply enters into thesethose commodity contracts to reduce the market risk inherent in the generation of electricity.

Starting in 2007, PPL Energy Supply elected to use an alternative method for disclosing quantitative information about market risk sensitive instruments. This method utilizes a VaR model to measure commodity price risk in its non-trading and trading portfolios. This approach is consistent with how PPL's Risk Manager assesses the market risk of its commodity business. VaR is a statistical model that attempts to predict risk of loss, under normal market conditions, based on historical market price volatility. PPL Energy Supply calculates VaR using a Monte Carlo simulation technique, which uses historical data from the past 12 month period. The VaR is the estimated nominal loss of earnings based on a one-day holding period at a 95% confidence interval. As of March 31, 2007, the VaR for PPL Energy Supply's non-trading portfolio was $16 million. This excludes the activity for PPL Energy Supply's synthetic fuel tax credit hedges. Additional information regarding these hedges can be found in the "Synthetic Fuel Tax Credit Risk" section below.

As of March 31, 2007, PPL Energy Supply estimated that a 10% adverse movement in market prices across all geographic areas and time periods would have decreased the value of the commodity contracts in its trading portfolio by $35 million, compared to $20 million as of March 31, 2006.

As of March 31, 2007, the VaR for PPL Energy Supply's trading portfolio was $4 million. This excludes the activity for PPL Energy Supply's synthetic fuels tax credits. Additional information regarding these hedges can be found in the "Synthetic Fuel Tax Credit Risk" section below.

Synthetic Fuel Tax Credit Risk

At this time, PPL Energy Supply expects that the high level and the volatility of crude oil prices will reduce the amount of synthetic fuel tax credits that PPL receives through its synthetic fuel production. The tax credits are reduced if the annual average wellhead price of domestic crude oil falls within a phase-out range. The tax credits are eliminated if this reference price exceeds the phase-out range. See "Regulatory Issues - IRS Synthetic Fuels Tax Credits" in Note 10 to the Financial Statements for more information regarding the phase-out of the tax credits.

PPL Energy Supply implemented a risk management strategy to hedge a portion of the variability of cash flows associated with its 2006 and 2007 synthetic fuel tax credits by hedging the risk that the 2006 and 2007 annual average wellhead price for domestic crude oil will be within the phase-out range.

PPL Energy Supply has net purchased options for 2007 that are expected to mitigate PPL Energy Supply's tax credit phase-out risk due to an increase of the average wellhead price in 2007. These positions did not qualify for hedge accounting treatment. The mark-to-market value of these positions at March 31, 2007, was a gain of $29 million. 

As of March 31, 2007, PPL Energy Supply estimated that a 10% adverse movement in market prices of crude oil would have decreased the value of the synthetic fuel hedges by $26 million. For purposes of this calculation, a decrease in the market price for crude oil is considered an adverse movement.

Commodity Price Risk Summary

In accordance with its marketing strategy, PPL Energy Supply doeselects not completelyto fully hedge its generation output or fuel requirements. PPL Energy Supply estimates that for its entire portfolio, including all generation, emissions and physical and financial energy positions, a 10% adverse change in power prices across all geographic zones and time periods would decrease expected 20062007 gross margins by $14$7 million. Similarly, aA 10% adverse movement in all fossil fuel prices would decrease 2006not have a material effect on 2007 gross margins by $31 million.

The data in the above tables includes the activity for PPL Energy Supply's synthetic fuel tax credit hedges. Additional information regarding these hedges can be found in the "Synthetic Fuel Tax Credit Risk" section below.

Commodity Price Risk (Trading)

PPL Energy Supply also executes energy contracts to take advantage of market opportunities. As a result, PPL Energy Supply may at times create a net open position in its portfolio that could result in significant losses if prices do not move in the manner or direction anticipated. The margins from these trading activities are shown in the Statement of Income as "Net energy trading margins."

As of March 31, 2006, PPL Energy Supply estimated that a 10% adverse movement in market prices across all geographic areas and time periods, excluding the effect of any commodity price correlations, would have decreased the value of the commodity contracts in its trading portfolio by $20 million.

Interest Rate Risk

PPL Energy Supply and its subsidiaries have issued debt to finance their operations.operations, which exposes them to interest rate risk. Both PPL and PPL Energy Supply manage interest rate risk for PPL Energy Supply by using various financial derivative products to adjust the mix of fixed and floating interest rates in PPL Energy Supply's debt portfolio, adjust the duration of its debt portfolio and lock in treasury rates (and interest rate spreads over treasuries) in anticipation of future financing, when appropriate. Risk limits under the risk management program are designed to balance risk exposure to volatility in interest expense and changes in the fair value of PPL Energy Supply's debt portfolio due to changes in the absolute level of interest rates.

At March 31, 2006,2007, PPL Energy Supply's potential annual exposure to increased interest expense, based on a 10% increase in interest rates, was $2$4 million.

PPL Energy Supply is also exposed to changes in the fair value of its domestic and international debt portfolios. At March 31, 2006,2007, PPL Energy Supply estimated that its potential exposure to a change in the fair value of its debt portfolio, through a 10% adverse movement in interest rates, was $140$282 million.

PPL and PPL Energy Supply utilize various risk management instruments to reduce PPL Energy Supply's exposure to the expected future cash flow variability of its debt instruments. These risks include exposure to adverse interest rate movements for outstanding variable rate debt and for future anticipated financing. While PPL Energy Supply is exposed to changes in the fair value of these instruments, any changes in the fair value of these instruments are recorded in equity and then reclassified into earnings in the same period during which the item being hedged affects earnings. At March 31, 2006,2007, the market value of these instruments,this position, representing the amount PPL Energy Supply would receive upon theirits termination, was $23$1 million. At March 31, 2006,2007, PPL Energy Supply estimated that its potential exposure to a change in the fair value of these instruments,this instrument, through a 10% adverse movement in the hedged exposure, was $28$2 million.

PPL and PPL Energy Supply also utilize various risk management instruments to adjust the mix of fixed and floating interest rates in PPL Energy Supply's debt portfolio. While PPL Energy Supply is exposed to changes in the fair value of these instruments, any change in market value is recorded with an equal and offsetting change in the value of the debt being hedged. At March 31, 2006,2007, PPL Energy Supply estimated that its potential exposure to a change in the fair value of these instruments, through a 10% adverse movement in interest rates, was $2$1 million.

WPDH Limited holds a net position in cross-currency swaps totaling $702 million to hedge the interest payments and principal of its U.S. dollar-denominated bonds with maturity dates ranging from December 2007 to December 2028.

Nuclear Decommissioning Trust Funds - Securities Price Risk

In connection with certain NRC requirements, PPL Susquehanna maintains trust funds to fund certain costs of decommissioning the Susquehanna nuclear station. As of March 31, 2006,2007, these funds were invested primarily in domestic equity securities and fixed-rate, fixed-income securities and are reflected at fair value on PPL Energy Supply's Balance Sheet. The mix of securities is designed to provide returns sufficient to be used to fund Susquehanna's decommissioning and to compensate for inflationary increases in decommissioning costs. However, the equity securities included in the trusts are exposed to price fluctuation in equity markets, and the values of fixed-rate, fixed-income securities in the trusts are exposed to changes in interest rates. PPL Susquehanna actively monitors the investment performance and periodically reviews asset allocation in accordance with its nuclear decommissioning trust policy statement. At March 31, 2006,2007, a hypothetical 10% increase in interest rates and a 10% decrease in equity prices would have resulted in an estimated $35$38 million reduction in the fair value of the trust assets. See the "Asset Retirement Obligations and Nuclear Decommissioning" Note 21 in the 2005PPL Energy Supply's 2006 Form 10-K for more information regarding the nuclear decommissioning trust funds.

Synthetic Fuel Tax Credit Risk
At this time, PPL Energy Supply expects that the current high level and the volatility of crude oil prices will reduce the amount of synthetic fuel tax credits that PPL Energy Supply receives through its synthetic fuel production. The tax credits are reduced if the annual average wellhead price of domestic crude oil falls within a phase-out range. The tax credits are eliminated if this reference price exceeds the phase-out range. See "Regulatory Issues - IRS Synthetic Fuels Tax Credits" in Note 11 to the Financial Statements for more information regarding the phase-out of the tax credits and shutdown of synfuel projects.

PPL Energy Supply implemented a risk management strategy to hedge a portion of the variability of cash flows associated with its 2006 and 2007 synthetic fuel tax credits by hedging the risk that the 2006 and 2007 annual average wellhead price for domestic crude oil will be within the phase-out range.

PPL Energy Supply purchased options in 2005 to mitigate some of the reductions in synthetic fuel tax credits if the annual average wellhead price for 2006 and 2007 falls within the applicable phase-out range. These positions did not qualify for hedge accounting treatment. The mark-to-market value of these positions at March 31, 2006, was a gain of $33 million. Of this total, $23 million was recorded during the three months ended March 31, 2006, and is reflected in "Energy-related businesses" revenues on the Statement of Income.

As of March 31, 2006, PPL Energy Supply estimated that a 10% adverse movement in market prices of crude oil would have decreased the value of the synthetic fuel hedges to a nominal amount. For purposes of this calculation, a decrease in the market price for crude oil is considered an adverse movement.

Related Party Transactions

PPL Energy Supply is not aware of any material ownership interests or operating responsibility by senior management of PPL Energy Supply in outside partnerships, including leasing transactions with variable interest entities, or other entities doing business with PPL Energy Supply.

For additional information on related party transactions, see Note 1211 to the Financial Statements.

Acquisitions, Development and Divestitures

From time to time, PPL Energy Supply and its subsidiaries are involved in negotiations with third parties regarding acquisitions and dispositions of businesses and assets, joint ventures and development projects which may or may not result in definitive agreements. Management is in the process of reviewing strategic alternatives for certain of its gas-fired generation assets. Any such transactions may impact future financial results. See Note 8 to the Financial Statements for information regarding such recent transactions.

PPL Energy Supply is currently planning incremental capacity increases of 270355 MW at several existing domestic generating facilities. Offsetting this increase is an expected 30 MW reduction in generation capability at each of the Brunner Island and Montour plants, due to the estimated increases in station service usage during the scrubber operation. See Note 10 to the Financial Statements for additional information, as well as information regarding the planned shut down of two 150 MW generating units at PPL Martins Creek in September 2007.

PPL Energy Supply is continuously reexamining development projects based on market conditions and other factors to determine whether to proceed with these projects, sell them, cancel them, expand them, execute tolling agreements or pursue other opportunities.

Environmental Matters

See Note 1110 to the Financial Statements for a discussion of environmental matters.

New Accounting Standards

See Note 1817 to the Financial Statements for a discussion of new accounting standards recently adopted or pending adoption.

Application of Critical Accounting Policies

PPL Energy Supply's financial condition and results of operations are impacted by the methods, assumptions and estimates used in the application of critical accounting policies. The following accounting policies are particularly important to the financial condition or results of operations of PPL Energy Supply, and require estimates or other judgments of matters inherently uncertain: price risk management, pension and other postretirement benefits, asset impairment, leasing, loss accruals and asset retirement obligations.

See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations," in PPL Energy Supply's 20052006 Form 10-K for a discussion of each critical accounting policy. PPL's senior management has reviewed these critical accounting policies, and the estimates and assumptions regarding them, with its Audit Committee. In addition, PPL's senior management reviewed the Form 10-K disclosures regarding the application of these critical accounting policies with the Audit Committee.

In June 2006, the FASB issued FIN 48, "Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109." In May 2007, the FASB amended this guidance by issuing FSP FIN 48-1, "Definition of Settlement in FASB Interpretation No. 48." PPL Energy Supply and its subsidiaries adopted FIN 48, as amended, effective January 1, 2007. The adoption of FIN 48 alters the methodology PPL Energy Supply previously used to account for income tax uncertainties. Effective with the adoption of FIN 48, uncertain tax positions are no longer considered to be contingencies assessed in accordance with SFAS 5, "Accounting for Contingencies." The following is an update to the "Income Tax Uncertainties" section of the "Loss Accruals" critical accounting policy disclosed in PPL Energy Supply's 2006 Form 10-K, which reflects the adoption of FIN 48.

Similar to SFAS 5, FIN 48 continues to require significant management judgment in determining the amount of benefit to be recognized in relation to an uncertain tax position. FIN 48 requires PPL Energy Supply to evaluate its tax positions following a two-step process. The first step requires an entity to determine whether, based on the technical merits supporting a particular tax position, it is more likely than not (greater than a 50 percent chance) that the tax position will be sustained. This determination assumes that the relevant taxing authority will examine the tax position and is aware of all the relevant facts surrounding the tax position. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The measurement of the benefit equals the largest amount of benefit that has a likelihood of realization, upon settlement, that exceeds 50 percent. PPL Energy Supply's management considers a number of factors in assessing the benefit to be recognized, including negotiation of a settlement.

On a quarterly basis, PPL Energy Supply reassesses its uncertain tax positions by considering information known at the reporting date. Based on management's assessment of new information, PPL Energy Supply may subsequently recognize a tax benefit for a previously unrecognized tax position, derecognize a previously recognized tax position, or remeasure the benefit of a previously recognized tax position.

The balance sheet classification of unrecognized tax benefits also requires significant management judgment. FIN 48 requires an entity to classify unrecognized tax benefits as current, to the extent management expects to settle an uncertain tax position, by paying cash, within one year of the reporting date.

Significant management judgment is also required in developing valuation allowances for deferred tax assets. Valuation allowances are initially recorded and reevaluated each reporting period by assessing the likelihood of the ultimate realization of a deferred tax asset. Management considers a number of factors in assessing the realization of a deferred tax asset, including forecasts of future taxable income and available tax planning strategies. Any tax planning strategy utilized in this assessment must meet the recognition and measurement criteria of FIN 48. See Note 5 to the Financial Statements for the disclosures required by FIN 48.

The following information should be read in conjunction with PPL Electric's Condensed Consolidated Financial Statements and the accompanying Notes.Notes and in conjunction with PPL Electric's 2006 Form 10-K.

Terms and abbreviations are explained in the glossary. Dollars are in millions unless otherwise noted.

Results of Operations

The following discussion, which explains significant changes in principal items on PPL Electric's StatementStatements of Income, compares the three months ended March 31, 2006,2007, with the comparablesame period in 2005.2006.

The StatementStatements of Income reflectsreflect the results of past operations and isare not intended as any indication of future operating results. Future operating results will necessarily be affected by various and diverse factors and developments. Furthermore, because results for interim periods can be disproportionately influenced by various factors and developments and by seasonal variations, the results of operations for interim periods do not necessarily indicate results or trends for the year.

Earnings

Income available to PPL was $51$52 million for the three months ended March 31, 2006,2007, compared with $15$51 million for the same period in 2005.2006.

The after-tax changeschange in income available to PPL werebetween these periods was due to:

Depreciation  (2) 
  $1  

The period-to-period changes in significant earnings components are explained in the "Statement of Income Analysis."

PPL Electric's period-to-period earnings were affected by a number of factors, including:

·PPL Electric recognized an after-tax charge of $27 million in the first quarter of 2005 for a loss contingency related to the PJM billing dispute. See Note 11 to the Financial Statements for an update on this matter. PPL Electric cannot be certain of the outcome of this matter or the impact on PPL Electric.
·Lower operation and maintenance expenses in the first quarter of 2006 were primarily due to the costs incurred in January 2005, when severe ice storms hit PPL Electric's service territory. The total cost of restoring service to 238,000 customers, excluding capitalized costs and regular payroll expenses, was $16 million.
In August 2005, the PUC issued an order granting PPL Electric's petition for authority to defer and amortize for regulatory accounting and reporting purposes these storm costs subject to certain conditions. As a result of the PUC Order and in accordance with SFAS 71, "Accounting for the Effects of Certain Types of Regulation," in the third quarter of 2005, PPL Electric deferred $12 million of its previously expensed storm costs. The deferral was based on its assessment of the timing and likelihood of recovering the deferred costs in PPL Electric's next distribution base rate case. At this time, PPL Electric cannot be certain that it will recover the storm costs, nor can it predict whether future incidents of severe weather will cause significant facility damage and service disruptions that would also result in significant costs.
including higher delivery revenues which were primarily due to a 4% increase in sales volumes, due in part to the impact of colder weather in 2007 on residential and commercial sales and the return of customers previously served by alternate suppliers.

2007 Outlook

PPL Electric projectsexpects to have flat revenuesearnings in 20062007 compared with 2005 due to favorable weather impacts in 2005 and an increase in2006, with modest load growth being offset by increased operation and maintenance expenses.

In March 2007, PPL Electric filed a request with the PUC to increase distribution rates by approximately $84 million. The PUC's review of the distribution rate request is expected to take about nine months. The proposed distribution rate increase would result in a 2.7% increase over PPL Electric's present rates and would be effective January 1, 2008. PPL Electric cannot predict the outcome of this proceeding.

Refer to PPL Electric's 2006 Form 10-K for information about PPL Electric's plan detailing how it proposes to acquire its PLR electricity supply for non-shopping customers in 2010 after its PLR contract with PPL EnergyPlus expires, as well as the PUC's proposed PLR regulations and policy statement regarding interpretation and implementation of those regulations. Based on current forward market prices, PPL Electric estimated that under its proposed plan customer rates could increase by approximately 30% from 2009 to 2010.

Preference Stock

In April 2006, PPL Electric sold 10 million depositary shares, each representing a quarter interest in a share of PPL Electric's 6.25% Series Preference Stock (Preference Shares), totaling $250 million. In connection with the sale of the depositary shares, PPL Electric issued 2.5 million Preference Shares, with a liquidation preference of $100 per share, to the bank acting as a depositary. The net proceeds of approximately $245 million from the offering were used to repurchase $200 million of PPL Electric's common stock held by PPL, and for other general corporate purposes.

Holders of the depositary shares are entitled to all proportional rights and preferences of the Preference Shares, including dividend, voting, redemption and liquidation rights, exercised through the depositary. The Preference Shares rank senior to PPL Electric's common stock and junior to its outstanding preferred stock, and they have no voting rights, except as provided by law.

Dividends on the Preference Shares will be paid when, as and if declared by the Board of Directors at a fixed annual rate of 6.25%, or $1.5625 per depositary share per year, and are not cumulative. PPL Electric may not pay dividends on, or redeem, purchase or make a liquidation payment with respect to any of its common stock, except in certain circumstances, unless full dividends on the Preference Shares have been paid for the then-current dividend period.

The Preference Shares do not have a stated maturity, and are not subject to sinking fund requirements. However, PPL Electric may, at its option, redeem the Preference Shares in whole or in part from time to time for $100 per share (equivalent to $25 per depositary share), plus any declared and unpaid dividends, on or after April 6, 2011. It is PPL Electric's intention to redeem or repurchase the Preference Shares only from the proceeds of the sale of certain qualifying securities having equity characteristics similar to or greater than the applicable equity characteristics of the Preference Shares. PPL Electric may decide to affirm this intention in the future by making an enforceable covenant in favor of holders of a specific series of its outstanding long-term debt securities.

Credit Facilities

In May 2007, PPL Electric is currently pursuing extendingexpects to extend the maturityexpiration date of its $200 million syndicated credit facility that expires in June 2010 by one year. PPL expects the extension to be effective in June 2006.May 2012.

Rating Agency Decisions

Moody's, S&P and Fitch periodically review the credit ratings on the debt and preferred securities of PPL Electric and its subsidiary, PPL Transition Bond Company. Based on their respective independent reviews, the rating agencies may make certain ratings revisions or ratings affirmations.

A credit rating reflects an assessment by the rating agency of the credit-worthinesscreditworthiness associated with an issuer and particular securities that it issues. The credit ratings of PPL Electric'sElectric and PPL Transition Bond Company's credit ratingsCompany are based on information provided by PPL Electric and other sources. The ratings of Moody's, S&P and Fitch are not a recommendation to buy, sell or hold any securities of PPL Electric or PPL Transition Bond Company. Such ratings may be subject to revisions or withdrawal by thesethe agencies at any time and should be evaluated independently of each other and any other rating that may be assigned to the securities. A downgrade in PPL Electric's or PPL Transition Bond Company's credit ratings could result in higher borrowing costs and reduced access to capital markets.

In March 2006, Moody's, upgraded the issuer rating ofS&P and Fitch did not take any actions related to PPL Electric to Baa1 from Baa2, upgradedor PPL Transition Bond Company during the ratingsfirst quarter of its First Mortgage Bonds and Senior Secured Bonds to A3 from Baa1 and upgraded the rating of its preferred stock to Baa3 from Ba1. Moody's stated that the upgrades were prompted by (i) expectations for higher earnings and cash flow over the next three years, (ii) the generally constructive regulatory situation for PPL Electric, which includes a pass through of generation-based energy costs related to its long-term, full-requirements power supply agreements that enable PPL Electric to meet its obligations as a PLR over the 2006-2009 period, and (iii) moderate expected growth in the volume of energy deliveries, which it indicated supports the expected stability of cash flows from regulated operations until the end of the regulatory transition period in 2009. Moody's acknowledged that the upgrade of PPL Electric takes into consideration the risk that PPL Electric may need to seek large rate increases in 2010, after the expiration of its current supply contracts, if market prices for wholesale power remain at or above current levels. Moody's indicated that the upgrade assumes that regulatory treatment will provide for reasonably timely recovery of increased costs and expenditures.2007.
In connection with PPL Electric's issuance of Preference Shares in April 2006, S&P affirmed all of PPL Electric's credit ratings.

Risk Management

Market Risk

Commodity Price Risk - PLR Contracts

PPL Electric and PPL EnergyPlus have power supply agreements under which PPL EnergyPlus sells to PPL Electric (under a predetermined pricing arrangement) energy and capacity to fulfill PPL Electric's PLR obligation through 2009. As a result, PPL Electric has shifted any electric price risk relating to its PLR obligation to PPL EnergyPlus through 2009. See Note 1211 to the Financial Statements for information on the PLR contracts.

Interest Rate Risk

PPL Electric has issued debt to finance its operations, which increases its interest rate risk. At March 31, 2006,2007, PPL Electric's potential annual exposure to increased interest expense, based on a 10% increase in interest rates, was $1 million.not significant.

PPL Electric is also exposed to changes in the fair value of its debt portfolio. At March 31, 2006,2007, PPL Electric estimated that its potential exposure to a change in the fair value of its debt portfolio, through a 10% adverse movement in interest rates, was $35$36 million.

Related Party Transactions

PPL Electric is not aware of any material ownership interests or operating responsibility by senior management of PPL Electric in outside partnerships, including leasing transactions with variable interest entities, or other entities doing business with PPL Electric.

See Note 1817 to the Financial Statements for a discussion of new accounting standards recently adopted or pending adoption.

Application of Critical Accounting Policies

PPL Electric's financial condition and results of operations are impacted by the methods, assumptions and estimates used in the application of critical accounting policies. The following accounting policies are particularly important to the financial condition or results of operations of PPL Electric, and require estimates or other judgments of matters inherently uncertain: pension and other postretirement benefits and loss accruals.

See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations," in PPL Electric's 20052006 Form 10-K for a discussion of each critical accounting policy. PPL's senior management has reviewed these critical accounting policies, and the estimates and assumptions regarding them, with its Audit Committee. In addition, PPL's senior management reviewed the Form 10-K disclosures regarding the application of these critical accounting policies with the Audit Committee.

In June 2006, the FASB issued FIN 48, "Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109." In May 2007, the FASB amended this guidance by issuing FSP FIN 48-1, "Definition of Settlement in FASB Interpretation No. 48." PPL Electric and its subsidiaries adopted FIN 48, as amended, effective January 1, 2007. The adoption of FIN 48 alters the methodology PPL Electric previously used to account for income tax uncertainties. Effective with the adoption of FIN 48, uncertain tax positions are no longer considered to be contingencies assessed in accordance with SFAS 5, "Accounting for Contingencies." The following is an update to the "Income Tax Uncertainties" section of the "Loss Accruals" critical accounting policy disclosed in PPL Electric's 2006 Form 10-K, which reflects the adoption of FIN 48.

Similar to SFAS 5, FIN 48 continues to require significant management judgment in determining the amount of benefit to be recognized in relation to an uncertain tax position. FIN 48 requires PPL Electric to evaluate its tax positions following a two-step process. The first step requires an entity to determine whether, based on the technical merits supporting a particular tax position, it is more likely than not (greater than a 50 percent chance) that the tax position will be sustained. This determination assumes that the relevant taxing authority will examine the tax position and is aware of all the relevant facts surrounding the tax position. The second step requires an entity to recognize in the financial statements the benefit of a tax position that meets the more-likely-than-not recognition criterion. The measurement of the benefit equals the largest amount of benefit that has a likelihood of realization, upon settlement, that exceeds 50 percent. PPL Electric's management considers a number of factors in assessing the benefit to be recognized, including negotiation of a settlement.

On a quarterly basis, PPL Electric reassesses its uncertain tax positions by considering information known at the reporting date. Based on management's assessment of new information, PPL Electric may subsequently recognize a tax benefit for a previously unrecognized tax position, derecognize a previously recognized tax position, or remeasure the benefit of a previously recognized tax position.

The balance sheet classification of unrecognized tax benefits also requires significant management judgment. FIN 48 requires an entity to classify unrecognized tax benefits as current, to the extent management expects to settle an uncertain tax position, by paying cash, within one year of the reporting date.

Significant management judgment is also required in developing valuation allowances for deferred tax assets. Valuation allowances are initially recorded and reevaluated each reporting period by assessing the likelihood of the ultimate realization of a deferred tax asset. Management considers a number of factors in assessing the realization of a deferred tax asset, including forecasts of future taxable income and available tax planning strategies. Any tax planning strategy utilized in this assessment must meet the recognition and measurement criteria of FIN 48. See Note 5 to the Financial Statements for the disclosures required by FIN 48.
