Tax-related - Alliant Energy’s and IPL’s tax-related regulatory assets are generally impacted by certain property-related differences at IPL for which deferred tax is not recorded in the income statement pursuant to Iowa rate-making principles. Deferred tax amounts for such property-related differences at IPL are recorded to regulatory assets, along with the necessary revenue requirement tax gross-ups. During the nine months ended September 30, 2015,2016, Alliant Energy’s and IPL’s tax-related regulatory assets increased primarily due to property-related differences for qualifying repair expenditures.
The July 2015 sale of IPL’s Minnesota electric distribution assets resulted in a reduction of certain tax-related regulatory assets on Alliant Energy’s and IPL’s balance sheets in 2015.
Derivatives - Refer to Note 12 for discussion of derivative assets and derivative liabilities.
IPL’s tax benefit riders - IPL’s tax benefit riders utilize regulatory liabilities to credit bills of IPL’s Iowa retail electric and gas customers to help offset the impact of rate increases on such customers. These regulatory liabilities are related to tax benefits from tax accounting method changes for repairs expenditures, allocation of mixed service costs, allocation of insurance proceeds from floods in 2008, and cost of removal expenditures. For the nine months ended September 30, 20152016, Alliant Energy’s and IPL’s “IPL’s tax benefit riders” regulatory liabilities decreased by $64$56 million as follows (in millions):

Electric transmission cost recovery -Utility Rate Cases -
WPL’s Wisconsin Retail Electric revenues establishedand Gas Rate Case (2017/2018 Test Period) - In May 2016, WPL filed a retail base rate case with the PSCW based on a forward-looking test period that includes 2017 and 2018. WPL’s filing was based on a stipulated agreement reached between PSCW staff, intervener groups and WPL. The filing requested approval for WPL to implement a $13 million, or approximately 1%, increase in annual rates for WPL’s retail electric customers. The net requested increase for 2017 compared to WPL’s retail electric rate case (2015/for the 2015/2016 Test Period) included recoveryPeriod reflected a $65 million increase in base rates, partially offset by a $52 million reduction in fuel-related costs, using a preliminary estimate for 2017 fuel-related costs. The filing also requested approval for WPL to implement a $9 million, or approximately 13%, increase in
annual base rates for WPL’s retail gas customers. Any rate changes granted from this request are expected to be incurred. Due toeffective January 1, 2017 and extend through the end of 2018. WPL currently expects a revisiondecision from the PSCW regarding this base rate case filing in MISO’s method to allocate System Support Resource costs, WPL no longer expects to incur certain System Support Resource costs. The difference between actual electric transmission service expense incurred and amounts collected from customers as electric revenues in 2015 are recorded as electric transmission service expense with an offsetting amount recorded to regulatory liabilities due to the escrow treatment authorized for WPL in its 2015/2016 Test Period retail electric rate case.fourth quarter of 2016.

WPL’s Retail Fuel-related Rate Filing (2016 Test Year) - In July 2015, WPL filed a request with the PSCW to increase annual rates for WPL’s retail electric customers by $15 million, or approximately 1%, in 2016. The increase reflects anticipated increases in retail electric fuel-related costs in 2016. Any rate changes granted from this request are expected to be effective on January 1, 2016. WPL currently expects a decision from the PSCW regarding this rate filing by the end of 2015.
WPL’s Retail Fuel-related Rate Filing (2015 Test Year) -Pursuant to a 20142015 PSCW order, WPL’s 20152016 fuel-related costs will be subject to deferral if they are outside an annual bandwidth of plus or minus 2% of the approved annual forecasted fuel-related costs. Retail fuel-related costs incurred by WPL through September 30, 20152016 were lower than fuel-related costs used to determine rates for such period resulting in an over-collection of fuel-related costs. As of September 30, 2015,2016, fuel-related costs outside of the approved range were $5$9 million and are included in “Commodity cost recovery” in Alliant Energy’s and WPL’s regulatory liabilities table above.

Emission Controls Project -
WPL’s Edgewater Unit 5 - WPL is currently constructing aConstruction of the scrubber and baghouse at Edgewater Unit 5 to reduce SO2 and mercury emissions at the EGU. Construction beganwas completed in 2014 and is expected to be completed inJuly 2016. As of September 30, 20152016, Alliant Energy and WPL recorded capitalized expenditures for construction work in progress of $171$223 million and AFUDC of $6$12 million for the scrubber and baghouse in “Property, plant and equipment, net” on their balance sheets.
Natural Gas-Fired Generation Project -
IPL’s Marshalltown Generating Station - IPL is currently constructing Marshalltown, an approximate 650 MW natural gas-fired combined-cycle EGU. Construction began in 2014 and is expected to be completed in the second quarter of 2017. As of September 30, 20152016, Alliant Energy and IPL recorded capitalized expenditures for construction work in progress of $414$600 million and AFUDC of $17$56 million for Marshalltown in “Property, plant and equipment, net” on their balance sheets.
Sales of IPL’s Minnesota Electric and Natural Gas Distribution Assets - In April 2015, IPL completed the sale of its Minnesota natural gas distribution assets and received proceeds of $11 million subject to post-closing adjustments based on the value of the net assets as of the closing date, and a promissory note of $2 million. In July 2015, IPL completed the sale of its Minnesota electric distribution assets (primarily related to property, plant and equipment) and received proceeds of $127 million, subject to post-closing adjustments based on the value of the net assets as of the closing date.$129 million. The proceeds from the natural gas distribution assets were used for general corporate purposes and the proceeds from the electric distribution assets were used to reduce cash proceedsamounts received from IPL’s sales of accounts receivable program. The premium received over the book value of the property, plant and equipment sold was more than offset by a reduction in tax-related regulatory assets associated with the distribution assets. As a result, Alliant Energy and IPL recorded pre-tax charges of $9 million and $3 million for the Minnesota electric and natural gas distribution asset transactions, respectively, in “Other operation and maintenance” in their income statements duringfor the nine months ended September 30, 2015.
In July 2015, FERC approved the wholesale power supply agreement between IPL and Southern Minnesota Energy Cooperative, which became effective upon the sale of IPL’s Minnesota electric distribution assets.

Corporate Services and OtherFranklin County Wind Farm - Corporate Services is implementing a new customer billing and information systemBased on an evaluation of the strategic options for IPL and WPL. Asthe Franklin County wind farm performed in the third quarter of 2016, Alliant Energy concluded, as of September 30, 2015,2016, it was probable the Franklin County wind farm will be transferred to IPL. As a result, Alliant Energy performed an impairment analysis of such assets in the third quarter of 2016. The impairment analysis evaluated the value of the assets and a reasonable estimate of the amount of costs associated with the Franklin County wind farm that would be allowed for recovery for IPL’s electric rate-making purposes. Based on various analyses, including discounted cash flows projected from the Franklin County wind farm, recently executed purchased power agreements associated with wind generating facilities located near the Franklin County wind farm, and the
cost of new wind farms identified through IPL’s planned wind expansion, the current value of the Franklin County wind farm assets as of September 30, 2016 was determined to be approximately $33 million, subject to working capital adjustments. Alliant Energy concluded such value represents a reasonable estimate of the amount IPL will be allowed for recovery for IPL’s electric rate-making purposes. As a result, the carrying amount of the Franklin County wind farm was reduced to its current value, resulting in non-cash, pre-tax asset valuation charges of $86 million (after-tax charges of $51 million, or $0.23 per share) in the third quarter of 2016. Alliant Energy recorded capitalized expenditures of $87 million and capitalized interest of $2 million for the system insuch charges as a reduction to “Property, plant and equipment, net” on its balance sheet.sheet in 2016 and charges to “Asset valuation charges for Franklin County wind farm” in its income statements for the three and nine months ended September 30, 2016.
TableIPL currently anticipates requesting approval from FERC in the fourth quarter of Contents2016 to transfer the Franklin County wind farm to IPL and expects to complete such transfer in the first quarter of 2017. The final amount to be recovered for IPL’s electric rate-making purposes will be determined by the IUB as part of IPL’s Iowa retail electric rate case for the 2016 Test Year, currently anticipated to be filed in the second quarter of 2017, and therefore the final asset valuation charges are subject to change.

(b) Whiting Petroleum Tax Sharing Agreement - Prior to an initial public offering of Whiting Petroleum in 2003, Alliant Energy and Whiting Petroleum entered into a tax separation and indemnification agreement pursuant to which Alliant Energy and Whiting Petroleum made certain tax elections. These tax elections had the effect of increasing the tax basis of the assets of Whiting Petroleum’s consolidated tax group based on the sales price of Whiting Petroleum’s shares in the initial public offering.

Performance ContingentRestricted Stock Units and Performance Restricted Units - Alliant Energy granted new types of share-based compensation awards to key employees in the first quarter of 2016 referred to as performance restricted stock units, performance restricted units and key employee performance restricted units. Payouts of these units are based on the achievement of certain performance targets (currently specified growth of consolidated income from continuing operations) during the three-year performance period. The actual number of units that will be paid out upon vesting is dependent upon actual performance and may range from zero to 200% of the target number of units. If performance targets are not met during the performance period, these units are forfeited. Subject to achievement of the performance criteria, payouts of nonvested units are prorated in the event of retirement, death or disability during the first year of the performance period based on time worked during the first year of the period, and are prorated upon involuntary termination without cause based on time worked during the entire period. Subject to achievement of the performance criteria, payouts of units to participants who terminate employment after the first year of the performance period due to retirement, death or disability are not prorated. Participants’ nonvested units are forfeited if the participant voluntarily leaves Alliant Energy or is terminated for cause during the performance period.
Performance Restricted Stock Units - Performance restricted stock units must be paid out in shares and are accounted for as equity awards. Each performance restricted stock unit’s value is based on the closing market price of one share of Alliant Energy’s common stock on the grant date of the award. A summary of the performance restricted stock units activity, with amounts representing the target number of units, was as follows:

Each key employee performance restricted unit’s final value is based on the closing market price of one share of Alliant Energy’s common stock on the grant date of the award. Compensation expense is recorded ratably over the performance period based on a probability assessment of payouts for the awards at each reporting period. A summary of the key employee performance restricted units activity, with amounts representing the target number of units, was as follows:
|

Restricted Stock Units and Restricted Units - Alliant Energy granted new types of share-based compensation awards to key employees in the first quarter of 2016 referred to as restricted stock units and restricted units. Payouts of these units are based on the expiration of a three-year time-vesting period. Payouts of nonvested units are prorated in the event of retirement, death or disability during the first year of the time-vesting period based on time worked during the first year of the period, and are prorated upon involuntary termination without cause based on time worked during the entire period. Upon expiration of the time-vesting period, payouts of units to participants who terminate employment after the first year of the period due to retirement, death or disability are not prorated. Participants’ nonvested units are forfeited if the participant voluntarily leaves Alliant Energy or is terminated for cause during the time-vesting period. Each restricted stock unit’s and restricted unit’s final value is based on the closing market price of one share of Alliant Energy’s common stock at the end of the time-vesting period. Compensation expense is recorded ratably over the performance period based on the fair value of the awards at each reporting period. Restricted stock units can be paid out in shares of Alliant Energy common stock, cash or a combination of cash and stock. Restricted units must be paid out in cash. Alliant Energy assumes it will make future payouts of its restricted stock units and restricted units in cash; therefore, restricted stock units and restricted units are accounted for as liability awards. A summary of the restricted stock units and restricted units activity was as follows:

(a) | In April 2015, the EPA published the final CCR Rule, which regulates CCR as a non-hazardous waste and iswas effective October 2015. IPL and WPL have nine and three coal-fired EGUs, respectively, with coal ash ponds that are impacted by this rule. In addition, IPL and WPL have four and two active CCR landfills, respectively, that are impacted by this rule. During the nine months ended September 30, 2015, Alliant Energy, IPL and WPL recognized additional AROs of $74 million, $57 million and $17 million, respectively, as a result of the final CCR Rule. The increases in AROs resulted in corresponding increases in “Property,property, plant and equipment, net”net on the respective balance sheets. Actual costs resulting from the CCR rule may be different than the amounts recorded during the nine months ended September 30, 2015 due to potential changes in compliance strategies that will be used, as well as other potential cost estimate changes. Expenditures incurred by IPL and WPL to comply with the CCR Rule are anticipated to be recovered in rates from their customers. |

Valuation Hierarchy - At each reporting date, Level 1 items included IPL’s 5.1% cumulative preferred stock, Level 2 items included certain non-exchange traded commodity contracts and substantially all of the long-term debt instruments, and Level 3 items included FTRs, certain non-exchange traded commodity contracts and IPL’s deferred proceeds.
Valuation Techniques -
Derivative assets and derivative liabilities - Derivative instruments are periodically used for risk management purposes to mitigate exposures to fluctuations in certain commodity prices, and transmission congestion costs and riskrail transportation costs. Risk policies are maintained that govern the use of such derivative instruments. Derivative instruments were not designated as hedging instruments and included the following:
|
| |
Risk management purpose | Type of instrument |
Mitigate pricing volatility for: | |
Electricity purchased to supply customers | Electric swap and physical forward contracts (IPL and WPL) |
Fuel used to supply natural gas-fired EGUs | Natural gas swap and physical forward contracts (IPL and WPL) |
Natural gas supplied to retail customers | Natural gas options and physical forward contracts (IPL and WPL) |
| Natural gas swap contracts (IPL) |
Fuel used at coal-fired EGUs | Coal physical forward contracts (IPL and WPL) |
Optimize the value of natural gas pipeline capacity | Natural gas physical forward contracts (IPL and WPL) |
| Natural gas swap contracts (IPL) |
Manage transmission congestion costs | FTRs (IPL and WPL) |
Manage rail transportation costs | Diesel fuel swap contracts (WPL) |
Swap, option and physical forward commodity contracts were non-exchange-based derivative instruments and were valued using indicative price quotations from a pricing vendor that provides daily exchange forward price settlements, from broker or dealer quotations, from market publications or from on-line exchanges. The indicative price quotations reflected the average of the bid-ask mid-point prices and were obtained from sources believed to provide the most liquid market for the commodity. A portion of these indicative price quotations were corroborated using quoted prices for similar assets or liabilities in active markets and categorized derivative instruments based on such indicative price quotations as Level 2. Commodity contracts that were valued using indicative price quotations based on significant assumptions such as seasonal or monthly shaping and indicative price quotations that could not be readily corroborated were categorized as Level 3. Swap, option and physical forward commodity contracts were predominately at liquid trading points. FTRs were valued using monthly or annual auction shadow prices from relevant auctions and were categorized as Level 3. Refer to Note 12 for additional details of derivative assets and derivative liabilities.
The fair value measurements of Level 3 derivative instruments include observable and unobservable inputs. The observable inputs are obtained from third-party pricing sources, counterparties and brokers and include bids, offers, historical transactions (including historical price differences between locations with both observable and unobservable prices) and executed trades. The significant unobservable inputs used in the fair value measurement of commodity contracts are forecasted electricity, natural gas and coal prices, and the expected volatility of such prices. Significant changes in any of those inputs would result in a significantly lower or higher fair value measurement.
Deferred proceeds (sales of receivables) - The fair value of IPL’s deferred proceeds related to its sales of accounts receivable program was calculated each reporting date using the cost approach valuation technique. The fair value represents the carrying amount of receivables sold less the allowance for doubtful accounts associated with the receivables sold and cash proceedsamounts received from the receivables sold due to the short-term nature of the collection period. These inputs were considered unobservable and deferred proceeds were categorized as Level 3. Deferred proceeds represent IPL’s maximum exposure to loss related to the receivables sold. Refer to Note 4(a)4 for additional information regarding deferred proceeds.
Long-term debt (including current maturities) - The fair value of long-term debt instruments was based on quoted market prices for similar liabilities at each reporting date or on a discounted cash flow methodology, which utilizes assumptions of current market pricing curves at each reporting date. Refer to Note 7(b) for additional information regarding long-term debt.
Cumulative preferred stock - The fair value of IPL’s 5.1% cumulative preferred stock was based on its closing market price quoted by the New York Stock Exchange at each reporting date.

Unrealized gains and losses from derivative instruments are generally recorded with offsets to regulatory assets or regulatory liabilities, based on fuel and natural gas cost recovery mechanisms, as well as other specific regulatory authorizations. Based on these recovery mechanisms, the changes in the fair value of derivative liabilities resulted in comparable changes to regulatory assets, and the changes in the fair value of derivative assets resulted in comparable changes to regulatory liabilities.

Credit Risk-related Contingent Features - Various agreements contain credit risk-related contingent features, including requirements to maintain certain credit ratings and/or limitations on liability positions under the agreements based on credit ratings. Certain of these agreements with credit risk-related contingency features are accounted for as derivative instruments. In the event of a material change in creditworthiness or if liability positions exceed certain contractual limits, credit support may need to be provided in the form of letters of credit or cash collateral up to the amount of exposure under the contracts, or the contracts may need to be unwound and underlying liability positions paid. TheAt September 30, 2016 and December 31, 2015, the aggregate fair value of all derivative instruments with credit risk-related contingent features in a net liability position as well aswas not materially different than amounts that would be required to be posted as credit support to counterparties by Alliant Energy, IPL or WPL if the most restrictive credit risk-related contingent features for derivative agreements in a net liability position were triggered, were as follows (in millions):triggered.

(c)NOTE 13(c) Legal Proceedings -
Flood Damage Claims - In June 2013, several plaintiffs purporting to represent a class of residential and commercial property owners filed a complaint against CRANDIC, Alliant Energy and various other defendants in the Iowa District Court for Linn County. Plaintiffs assert claims of negligence and strict liability based on their allegations that CRANDIC (along with other defendants) caused or exacerbated flooding of the Cedar River in June 2008. In July 2013, the case was removed from state court to federal court based on federal jurisdiction. In September 2013, the U.S. District Court for the Northern District of Iowa dismissed the Plaintiffs’ claims and transferred the case for resolution to the Surface Transportation Board, the administrative agency that oversees the Interstate Commerce Commission Termination Act. In October 2013, the Plaintiffs appealed the federal court’s dismissal of the case to the Eighth Circuit Court of Appeals. In May 2015, the Eighth Circuit Court of Appeals vacated the U.S. District Court for the Northern District of Iowa’s decision and ordered the case remanded back toFebruary 2016, the Iowa District Court for Linn County.County ruled in favor of Alliant Energy and CRANDIC believeand dismissed all claims against them, resulting in no loss. In August 2016, the case is without merit and will continue to vigorously contestIowa District Court for Linn County dismissed all claims against the case. Asremaining defendants. In September 2016, plaintiffs filed a result,notice of appeal with the Supreme Court of Iowa. Alliant Energy does not currently believe any material losses from these claimsfor this complaint are both probable and reasonably estimated, and therefore has not recognized any material loss contingency amounts for this complaint as of September 30, 2015. Due to the lack of specific damages identified and the procedural nature of the activity to date, Alliant Energy is currently unable to provide an estimate of potential loss or range of potential loss.2016.
(d)NOTE 13(d) Guarantees and Indemnifications -
RMT - In 2013, Alliant Energy sold RMT. RMT provided renewable energy services, including construction and high voltage connection services for wind and solar projects. As part of the sale, Alliant Energy indemnified the buyer for any claims, including claims of warranty under the project obligations that were commenced or are based on actions that occurred prior to the sale, except for liabilities already accounted for through adjustments to the purchase price. The indemnification obligations either cease to exist when the statute of limitation for such claims is met or, in the case of RMT’s projects, when the warranty period under the agreements expires. The contractual warranty periods for RMT’s projects generally range from 12 to 60 months with the latest expiring in 2016. Limited warranties may be extended in certain cases for warranty work performed.
Alliant Energy also continues to guarantee RMT’s performance obligations related to certain of RMT’s projects that were commenced prior to Alliant Energy’s sale of RMT. As of September 30, 2015,2016, Alliant Energy had $123 million of performance guarantees outstanding, with $48 million and $75 million currently expected to expire in 2016 and 2017, respectively. The expiration of these performance guarantees may be extended depending on when all valid warranty claims are resolved for the respective projects.
Although Alliant Energy has received warranty claims related to certain of these projects, it does not currently believe that material losses are both probable and reasonably estimated, and therefore, has not recognized any material liabilities related to these matters as of September 30, 2015.2016. Alliant Energy does not currently believe that the range of future potential loss from any warranty claims will be material. Refer to Note 16 for further discussion of RMT, including amounts Alliant Energy recorded to “Operating expenses” during the nine months ended September 30, 20152016 and 20142015 related to certain warranty claims.
Whiting Petroleum - In 2004, Alliant Energy sold its remaining interest in Whiting Petroleum. Whiting Petroleum is an independent oil and gas company. Alliant EnergyResources, as the successor to a predecessor entity that owned Whiting Petroleum, continues to guarantee the partnership obligations relatedof an affiliate of Whiting Petroleum under general partnership agreements in the oil and gas industry, including with respect to the future abandonment of certain platforms off the coast of California and related onshore plant and equipment that were owned by Whiting Petroleum prior to Alliant Energy’s sale of Whiting Petroleum.the partnerships. The guarantee doesguarantees do not include a maximum limit. As of September 30, 20152016, the present value of the abandonment obligations is estimated at $27$30 million. Alliant Energy believesis not aware of any material liabilities related to these guarantees of which it is probable that no paymentsResources will be made under this guarantee. Alliant Energyobligated to pay and therefore has not recognized any material liabilities related to this guarantee as of September 30, 2015.2016.
IPL’s Minnesota Electric Distribution Assets - IPL provided indemnifications associated with the July 2015 sale of its Minnesota electric distribution assets for losses resulting from potential breach of IPL’s representations, warranties and obligations under the sale agreement. Alliant Energy and IPL believe the likelihood of having to make any material cash payments under these indemnifications is remote. IPL has not recorded any material liabilities related to these indemnifications as of September 30, 2015.2016. The general terms of the indemnifications provided by IPL included a maximum limit of $17 million and expire in October 2020. Refer to Note 3 for further discussion of the sale of IPL’s Minnesota electric distribution assets.
NOTE 13(e) Environmental Matters -
MGP Sites - IPL and WPL have current or previous ownership interests in various sites that are previously associated with the production of gas for which IPL and WPL have, or may have in the future, liability for investigation, remediation and monitoring costs. IPL and WPL are working pursuant to the requirements of various federal and state agencies to investigate, mitigate, prevent and remediate, where necessary, the environmental impacts to property, including natural resources, at and around these former MGP sites in order to protect public health and the environment. IPL and WPL are currently monitoring and/or remediating 2423 and 5 sites, respectively. No longer included in IPL’s sites is a Minnesota site for which responsibility of the site was transferred to the buyer as part of the sale of IPL’s Minnesota natural gas distribution assets completed in April 2015.
Environmental liabilities related to the MGP sites are recorded based upon periodic studies. Such amounts are based on the best current estimate of the remaining amount to be incurred for investigation, remediation and monitoring costs for those sites where the investigation process has been or is substantially completed, and the minimum of the estimated cost range for those sites where the investigation is in its earlier stages. There are inherent uncertainties associated with the estimated remaining costs for MGP projects primarily due to unknown site conditions and potential changes in regulatory agency requirements. It is possible that future cost estimates will be greater than current estimates as the investigation process proceeds and as additional facts become known. The amounts recognized as liabilities are reduced for expenditures incurred and are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted. At September 30, 20152016, estimated future costs expected to be incurred for the investigation, remediation and monitoring of the MGP sites, as well as environmental liabilities recorded on the balance sheets for these sites, were as follows (in millions):

The recovery of such costs will be decided by IPL’s regulators in future rate cases or other proceedings. Alliant Energy and IPL currently do not expect to recover costs related to the civil penalty from IPL’s electric customers.
Other Environmental Contingencies - In addition to the environmental liabilities discussed above, various environmental rules are monitored that may have a significant impact on future operations. Several of these environmental rules are subject to legal challenges, reconsideration and/or other uncertainties. Given uncertainties regarding the outcome, timing and compliance plans for these environmental matters, the complete financial impact of each of these rules is not able to be determined; however future capital investments and/or modifications to EGUs to comply with certain of these rules could be significant. Specific current, proposed or potential environmental matters include, among others: Cross-State Air Pollution Rule, Clean Air Visibility Rule, Mercury and Air Toxic Standard Rule, Industrial Boiler and Process Heater Maximum Achievable Control Technology Rule, Ozone NAAQS Rule, SO2 NAAQS Rule, Federal Clean Water Act including Section 316(b), Effluent Limitation Guidelines, Hydroelectric Fish Passage Device, CCR Rule, and various legislation and EPA regulations to monitor and regulate the emission of greenhouse gases, including carbon emissions from new (CAA Section 111(b)) and existing (CAA Section 111(d)) fossil-fueled EGUs. Some recent developments concerning these environmental matters are included below:
Air Quality -
Ozone NAAQS Rule - In October 2015, the EPA published a final revised Ozone NAAQS Rule, which is more stringent than the previous version of the rule and may require NOx emission reductions in certain non-attainment areas designated by the EPA. The EPA’s final designations of non-attainment areas for this revised rule are currently expected to be issued by October 2017. Compliance deadlines range from 2020 through 2037 depending on the level of NOx emissions in non-attainment areas.
Clean Air Act Section 111(d) - In October 2015, the EPA published final standards under Section 111(d) of the CAA, which establish guidelines for states to follow in developing plans to reduce carbon dioxide emissions from existing fossil-fueled EGUs. The final standards include an interim compliance period from 2022 through 2029 and a final compliance requirement beginning in 2030. The EPA also published a proposed federal plan that would be implemented in states that do not complete a fully approved state plan.
Clean Air Act Section 111(b) - In October 2015, the EPA published final standards under Section 111(b) of the CAA, which establish carbon dioxide emissions limits for certain new fossil-fueled EGUs. Marshalltown and WPL’s proposed Riverside expansion are expected to be impacted by these standards. Marshalltown is being constructed, and WPL’s proposed Riverside expansion is being designed, to achieve compliance with these standards.
Water Quality -
Effluent Limitation Guidelines - In November 2015, the EPA published final effluent limitation guidelines, which require changes to discharge limits for wastewater from steam generating facilities. Compliance will be required after November 1, 2018 but before December 31, 2023, depending on each facility’s wastewater permit renewal cycle for existing steam generating facilities and immediately upon operation for new steam generating facilities constructed after the effective date of the final guidelines.
Land and Solid Waste -
CCR Rule - Refer to Note 10 for discussion of the final CCR Rule, including additional AROs that were recognized during the nine months ended September 30, 2015 related to such rule.

In April 2015, IPL completed the sale of its Minnesota natural gas distribution assets, which qualified as held for sale as of December 31, 2014. In July 2015, IPL completed the sale of its Minnesota electric distribution assets. Alliant Energy and IPL evaluated the sales of IPL’s Minnesota electric and natural gas distribution assets and believe such sales did not represent a strategic shift that has, or will have, a major effect on their operational and financial results. As a result, the operating results of IPL’s Minnesota electric and natural gas distribution assets have not been separately classified and reported as discontinued operations in Alliant Energy’s and IPL’s income statements.
As of December 31, 2014, Alliant Energy’s and IPL’s balance sheets included assets held for sale related to IPL’s Minnesota natural gas distribution assets recorded in “Other current assets” and liabilities held for sale recorded in “Other current liabilities” as follows (in millions):

The table above includes EPS from continuing operations for utilities, ATC and Corporate Services, and non-regulated and parent, which are non-GAAP financial measures. Alliant Energy believes EPS from continuing operations for utilities, ATC and Corporate Services, and non-regulated and parent are useful to investors because they facilitate an understanding of segment performance and trends and provide additional information about Alliant Energy’s operations on a basis consistent with the measures that management uses to manage its operations and evaluate its performance.
Utilities, ATCLower net income and Corporate Services - Higher EPS from continuing operations in the third quarter of 20152016 compared to the third quarter of 20142015 was primarily due to:
$0.11 per share of lower retail electric customer billing credits at IPLto asset valuation charges related to the Franklin County wind farm in the third quarter of 2015 compared to the third quarter2016, timing of 2014 related to an approved settlement agreement in 2014income tax expense, higher reserves for its IowaATC return on equity at WPL, and higher stock-based performance compensation expense. These items were partially offset by estimated temperature impacts on retail electric base rates;
an estimated $0.06 per share of higher estimated temperature-normalized retail electricand gas sales in the third quarter of 2015 compared to the third quarter of 2014;
$0.06 per share of lower energy efficiency cost recovery amortizations at WPL in the third quarter of 2015 compared to the third quarter of 2014;
an estimated $0.05 per share of increases in revenues from2016, higher electric sales in the third quarter of 2015 compared to the third quarter of 2014 due to colder temperatures in the third quarter of 2014;AFUDC, and
$0.04 per share of lower other operation and maintenance expenses.
These items were partially offset by:
$0.04 per share of higher electric transmission service expense at WPL in the third quarter of 2015 compared to the third quarter of 2014;
$0.04 per share related to the dilution impact of shares issued under the at-the-market offering program and Shareowner Direct Plan in 2015; and
$0.04 per share related to voluntary employee separation charges in the third quarter of 2015.
Non-regulated and Parent - Higher EPS in the third quarter of 2015 compared to the third quarter of 2014 was primarily due to $0.02 per share related to the timing of income tax expense at the Parent in the third quarter of 2015 compared to the third quarter of 2014, which is not expected to have a material impact on the full year results.
Refer to “Results of Operations” for additional details regarding the various factors impacting earnings during the third quarters of 20152016 and 20142015.
Strategic Overview Highlights
The2016 Overview - Alliant Energy, IPL and WPL continue to focus on achieving financial objectives and executing their strategic plan, focuses on the core business of delivering regulated electric and natural gas service in Iowa and Wisconsin, and is built upon three key elements:including providing competitive value and exceptional service for their customers and responsiblefinding innovative ways to operate the business more efficiently and provide flexible energy resources. Key strategic plan developments since the filing of the 20142015 Form 10-K include the following.following:
| |
• | IPL’s Expansion of Wind Generation - In October 2016, IPL and the Iowa Office of Consumer Advocate, among other customer groups, filed a settlement agreement with the IUB regarding the appropriate rate-making principles for up to 500 MW of additional wind generation at IPL. In October 2016, the IUB issued an order approving the settlement agreement, with limited modifications, and establishing rate-making principles, which IPL accepted, with key terms as follows. Refer to “Strategic Overview” for further discussion. |
| |
▪ | Up to 500 MW of additional wind generation that qualifies for the full level of production tax credits, regardless of the location in Iowa, with a cost cap of $1,830/kilowatt, including AFUDC and transmission costs. Any costs incurred in excess of this $1,830/kilowatt cost cap are expected to be incorporated into rates if determined to be reasonable and prudent. |
| |
▪ | A depreciable life of the wind generation of 40 years, unless changed as a result of a contested case before the IUB. |
| |
▪ | An 11.0% return on common equity, with the exception of certain transmission facilities classified as intangible assets, which would earn the rate of return on common equity the IUB finds reasonable during a future rate case. |
Franklin County Wind Farm - In addition to “Strategic Overview” for a more detailed discussionIPL’s expansion of strategic plan developments.wind generation discussed above, IPL currently anticipates requesting approval from FERC in the fourth quarter of 2016 to transfer the 99 MW Franklin County wind farm from AEF to IPL in 2017.

Alliant Energy and IPL are currently unable to determine any resulting changes to future electric transmission service charges pending a decision by FERC on the 2013 complaint.
STRATEGIC OVERVIEW
A strategic overview summary is included in the 2014 Form 10-K and has not changed materially from the items reported in the 2014 Form 10-K, except as described below.
Generation Plans -
Natural Gas-Fired Generation -
WPL’s Proposed Construction of the Riverside Expansion - In April 2015, WPL filed a Certificate of Public Convenience and Necessity application with the PSCW for approval to construct an approximate 650MW natural gas-fired combined-cycle EGU in Beloit, Wisconsin, referred to as the Riverside expansion. In November 2015, WPL filed testimony with the PSCW that included an updated cost estimate for the Riverside expansion. Capital expenditures, excluding AFUDC, are currently estimated to be approximately $680 million to $720 million to construct the EGU and a pipeline to supply natural gas to the EGU. Intervenors in the docket have challenged the Riverside expansion by raising questions about the project need and have offered alternatives. A decision from the PSCW on WPL’s application is currently expected by May 2016. The Riverside expansion is also subject to the receipt of various approvals and permits necessary to construct and operate the EGU and connect such EGU to the transmission system.
Coal-Fired Generation -
Plant Retirements or Fuel Switching - IPL currently plans to fuel switch from coal to natural gas at, or retire, the following EGUs:
|
| | | | |
EGU (In-Service Year) | | Nameplate Capacity | | Expected Action |
Prairie Creek Unit 4 (1967) | | 149 MW | | Fuel switch by December 31, 2017 |
Burlington Generating Station (1968) | | 212 MW | | Fuel switch by December 31, 2021 |
Prairie Creek Units 1 and 3 (1997 and 1958, respectively) | | 64 MW | | Fuel switch or retire by December 31, 2025 |
In addition, IPL’s M.L. Kapp Unit 2 fuel type was switched from coal to natural gas in June 2015.
The above plans are consistent with IPL’s requirements specified in the Consent Decree, which is discussed in Note 13(e).
Electric and Gas Distribution Systems - An important aspect of the strategic plan focuses resources on providing safe and reliable electric and natural gas service to IPL’s and WPL’s customers. Investments are expected to be targeted in replacing, modernizing and upgrading aging infrastructure in the electric and gas distribution systems. These investments will make the electric distribution system more resilient, robust and flexible to be able to meet customers’ changing and growing needs. Investments are also expected in the gas distribution system to ensure the system is appropriately maintained and operated safely. In addition, investments are expected to be made to extend various gas transmission and distribution systems in IPL’s and WPL’s service territories to serve new customer demand. Estimated capital expenditures for these expected and current projects for 2015 through 2019 are included in the “Electric and gas distribution systems” lines in the construction and acquisition expenditures table in “Liquidity and Capital Resources.”
IPL’s Proposed Clinton Natural Gas Pipeline - In September 2015, IPL filed a petition with the IUB for a pipeline permit to construct, maintain, and operate a natural gas pipeline in Scott and Clinton Counties in Iowa, referred to as the Clinton pipeline. IPL currently expects to receive the IUB’s decision on its petition in the second quarter of 2016. Subject to such approval, construction is expected to be completed by December 31, 2016. Capital expenditures to construct the pipeline, excluding AFUDC, are currently estimated to be approximately $60 million to $70 million.
Utility Business Divestitures -
IPL’s Minnesota Electric and Natural Gas Distribution Assets - Refer to Note 3 for discussion of the sales of IPL’s Minnesota electric and natural gas distribution assets, which were completed in July 2015 and April 2015, respectively.
Environmental Compliance Plans - Environmental compliance plans have been developed to help ensure cost effective compliance with current and proposed environmental laws and regulations. The following table provides current estimates of the total (past and future) project costs for certain emission controls projects included in the current environmental compliance plans (in millions):
|

Edgewater Unit 5 | | 2016 | | Scrubber & Baghouse | | 260-280 |
Columbia Unit 2 | | 2018 | | SCR | | 40-60 |
These capital expenditure estimates represent IPL’s or WPL’s respective portion of the total escalated capital expenditures and exclude AFUDC, if applicable. Capital expenditure estimates are subject to change based on future changes to plant-specific costs of emission controls technologies and environmental requirements.
IPL’s Emission Controls Projects - In March 2015, the IUB approved IPL’s most recent Emissions Plan and Budget, which includes a scrubber that IPL placed in service at Lansing Unit 4 in June 2015 to reduce SO2 emissions at the EGU. IPL’s previous Emissions Plan and Budget also included the scrubber at Lansing Unit 4.
Ottumwa Unit 1 - IPL currently plans to install an SCR system at Ottumwa Unit 1 to reduce NOx emissions at the EGU. The SCR is expected to support compliance obligations for current and anticipated air quality requirements, including the Cross-State Air Pollution Rule, and requirements under IPL’s Consent Decree.
RATE MATTERS
A rate matters summary is included in the 2014 Form 10-K and has not changed materially from the items reported in the 2014 Form 10-K, except as described below.
WPL’s Retail Fuel-related Rate Filings - Refer to Note 2 for discussion of WPL’s retail fuel-related rate filings for the Test Years 2014 though 2016.
Planned Utility Rate Cases -
WPL’s Wisconsin Retail Electric and Gas Rate Case (2017/2018 Test Period) - In May 2016, WPL currently expects to makefiled a retail electric and gasbase rate filing by June 30, 2016case with the PSCW based on a forward-looking test period that may include calendar yearsincludes 2017 and 2018. WPL’s filing was based on a stipulated agreement reached between PSCW staff, intervener groups and WPL. The key driversfiling requested approval for WPL to implement a $13 million, or approximately 1%, increase in annual rates for WPL’s retail electric customers. Based on updated fuel-related cost information at the anticipated filing include recoverytime of rate case hearings in September 2016, the current estimate of the SCR project at Columbia Unit 2, return on construction worknet increase in progress capital expendituresannual rates for the proposed Riverside expansion and other capital projects.WPL’s retail electric customers is $17 million. The filing also requested approval for WPL to implement a $9 million, or approximately 13%, increase in annual base rates for WPL’s retail gas customers. Any rate changes granted from this request are expected to be effective January 1, 2017 and extend through the end of 2018. WPL currently expects a decision from the PSCW regarding this base rate filing in Januarythe fourth quarter of 2016.
MISO Transmission Owner Return on Equity Complaints - A group of MISO cooperative and municipal utilities previously filed two complaints with FERC requesting a reduction to the base return on equity used by MISO transmission owners, including ITC and ATC. In September 2016, FERC issued an order on the first complaint and established a base return on equity of 10.32%, excluding any incentive adders granted by FERC, for the refund period from November 12, 2013 through February 11, 2015. In October 2016, in response to MISO’s and the MISO transmission owners’ request, FERC ordered the related refunds be issued by July 2017. In June 2016, a FERC administrative law judge issued an initial decision regarding the second complaint and recommended a base return on equity of 9.70%, excluding any incentive adders granted by FERC, for the refund period from February 12, 2015 through May 11, 2016. A final decision from FERC on the second complaint is currently expected in the first half of 2017.
WPL’s Future Transfer of Investment in ATC - In June 2016, WPL received an order from the PSCW requiring WPL to transfer its investment in ATC to Alliant Energy or an Alliant Energy subsidiary by December 31, 2022. In addition, WPL is required to obtain PSCW approval prior to transferring any additional capital or assets to ATC.Subsequent to WPL transferring its investment in ATC, future contributions to, and equity earnings and dividends from, the investment in ATC would occur at the entity to which the investment in ATC was transferred and would not be reflected in WPL’s consolidated financial statements. As a result, WPL’s earnings and cash flows from operations are expected to decrease subsequent to the transfer. This transfer is not expected to impact Alliant Energy’s consolidated financial statements.
Credit Ratings - In July 2016, Moody’s Investors Service changed Alliant Energy’s and IPL’s corporate/issuer and senior unsecured long-term debt credit ratings from A3 to Baa1. IPL’s preferred stock credit rating also changed from Baa2 to Baa3. In addition, WPL’s corporate/issuer and senior unsecured long-term debt credit ratings changed from A1 to A2. Alliant Energy’s, IPL’s and WPL’s outlooks also changed from negative to stable. Alliant Energy’s, IPL’s and WPL’s commercial paper ratings remained unchanged. These credit ratings changes are not expected to have a material impact on Alliant Energy’s, IPL’s, and WPL’s liquidity or collateral obligations.
Common Stock Split-In April 2016, Alliant Energy’s Board of Directors approved a two-for-one common stock split and a proportionate increase in the number of authorized shares of common stock of Alliant Energy from 240 million shares to 480 million shares to implement the stock split. Alliant Energy shareowners of record at the close of business on May 4, 2016 received one additional share of Alliant Energy common stock for each share held on that date. The proportionate interest that a shareowner owns in Alliant Energy did not change as a result of the stock split. The additional shares were distributed on May 19, 2016 and post-split trading began on May 20, 2016. All Alliant Energy share and per share amounts in this report have been reflected on a post-split basis.
IPL’s Iowa Retail Electric and Gas Rate Cases (2016 Test Year)Future Developments - IPL currently expects to make separate retail electric and gas rate filings in the second quarter of 2017 based on a 2016 historical test year. The following includes key drivers for the anticipated filings include recovery of capital projects, including Marshalltown for the electric filing and the proposed Clinton natural gas pipeline for the gas filing. Any rate changes areitems expected to be implemented in two phases with interim rates effective approximately 10 days after the filing and final rates effective approximately 10 months after the filing date.
Planned Retirement of WPL’s Nelson Dewey Units 1 and 2 and Edgewater Unit 3 - WPL previously announced plans to retire Nelson Dewey Units 1 and 2 and Edgewater Unit 3 by December 31, 2015. WPL is currently recovering the remaining net book value of these EGUs from both its retail and wholesale customers over a 10-year period beginning January 1, 2013 pursuant to orders previously issued by the PSCW and FERC. In October 2015, WPL filed a request with FERC to continue recovery of the wholesale portion of the remaining net book value of these EGUs over the same 10-year recovery period subsequent to the retirement of such EGUs. A decision is currently expected from FERC by December 31, 2015. Continued recovery of the retail portion of the remaining net book value of these EGUs is expected to be addressed in WPL’s next retail electric base rate case.
ENVIRONMENTAL MATTERS
An environmental matters summary is included in the 2014 Form 10-K and has not changed materially from the items reported in the 2014 Form 10-K, except as described below.
Air Quality -
Ozone NAAQS Rule - In October 2015, the EPA published a final revised Ozone NAAQS Rule, which is more stringent than the previous version of the rule and may require NOx emission reductions in certain non-attainment areas designated by the EPA. The EPA’s final designations of non-attainment areas for this revised rule are currently expected to be issued by October 2017. Compliance deadlines range from 2020 through 2037 depending on the level of NOx emissions in non-attainment areas. Depending on the level and location of non-attainment areas,impact Alliant Energy, IPL and WPL may be subjectin the future that have been identified since the filing of the 2015 Form 10-K:
2017 Forecast - In 2017, the following financing activities, and impacts to additional NOx emissions reduction requirementsresults of operations, are currently anticipated to meet the revised ozone NAAQS rule. However, occur:
Financing Plans - Alliant Energy currently expects to issue up to $150 million of common stock in 2017 through one or more offerings and its Shareowner Direct Plan. IPL and WPL currently expect to receive capital contributions of approximately $150 million and $90 million, respectively, from their parent company, Alliant Energy, in 2017. IPL and WPL currently expect to issue up to $250 million and $300 million, respectively, of long-term debt securities in 2017.
Common Stock Dividends - Alliant Energy announced an increase in its targeted 2017 annual common stock dividend to $1.26 per share, which is equivalent to a quarterly rate of $0.315 per share, beginning with the February 2017 dividend payment. The timing and amount of future dividends is subject to an approved dividend declaration from Alliant Energy’s Board of Directors, and is dependent upon earnings expectations, capital requirements, and general financial business conditions, among other factors. In addition, IPL and WPL currently expect to pay common stock dividends of $156 million and $126 million, respectively, to their parent company in 2017.
Electric Transmission Service Expense - Alliant Energy currently expects a decrease in electric transmission service expense in 2017 compared to 2016 primarily due to expected lower return on equity resulting from the MISO transmission owner return on equity complaints. Alliant Energy’s estimated 2017 electric transmission service expense remains subject to change pending the IUB’s approval of IPL’s 2017 transmission rates and the PSCW’s final decision in WPL’s retail electric rate case for the 2017/2018 Test Period. Based on IPL’s and WPL’s electric transmission cost recovery mechanisms, IPL and WPL currently do not currently believe thereexpect that any changes to electric transmission service costs billed by ITC and ATC will behave a significantmaterial impact on their financial condition and results of operations.
Greenhouse Gases Emissions -
Clean Air Act Section 111(d) - In October 2015, the EPA published final standards under Section 111(d) of the CAA, which establish guidelines for states to follow in developing plans to reduce carbon dioxide emissions from existing fossil-fueled EGUs. The final standards include an interim compliance period from 2022 through 2029 and a final compliance requirement beginning in 2030. The EPA also published a proposed federal plan that would be implemented in states that do not complete a fully approved state plan. Given Alliant Energy, IPL and WPL are currently reviewingcould have a material impact on their cash flows depending on the final standards and proposed federal plan,timing of refunds resulting from the MISO return on equity complaints, and the EPA’s rulemaking remains subjectsubsequent timing of the refunds being credited to legal challenges, Alliant Energy, IPL and WPL are currently unable to predict with certainty the impact of these standards, but expect that expenditures to comply with these standards could be significant.their customers.
Clean Air Act Section 111(b) - In October 2015, the EPA published final standards under Section 111(b) of the CAA, which establish carbon dioxide emissions limits for certain new fossil-fueled EGUs. Marshalltown and WPL’s proposed Riverside expansion are expected to be impacted by these standards. Marshalltown is being constructed, and WPL’s proposed Riverside expansion is being designed, to achieve compliance with these standards.
IPL Consent Decree - Refer to Note 13(e) for discussion of a Consent Decree approved by the U.S. District Court for the Northern District of Iowa in September 2015 and IPL’s obligations thereunder. The Consent Decree resolves discussions regarding CAA issues associated with emissions from IPL’s coal-fired generating facilities in Iowa.
Water Quality -
Effluent Limitation Guidelines - In November 2015, the EPA published final effluent limitation guidelines, which require changes to discharge limits for wastewater from steam generating facilities. IPL and WPL have identified ten (Emery Units 1-3, Ottumwa Unit 1, Prairie Creek Units 3-4, Fox Lake Units 1 and 3, Lansing Unit 4, Dubuque Units 3-4, Burlington Unit 1, Sutherland Units 1 and 3, George Neal Units 3-4 and Louisa Unit 1) and four (Riverside Units 1-3, Columbia Units 1-2, Nelson Dewey Units 1-2 and Edgewater Units 3-5) existing steam generating facilities, respectively, that are expected to be impacted by these guidelines. In addition, Marshalltown and WPL’s proposed Riverside expansion are expected to be impacted by these guidelines. Compliance with the final guidelines will be required after November 1, 2018 but before December 31, 2023, depending on each facility’s wastewater permit renewal cycle for existing steam generating facilities and immediately upon operation for new steam generating facilities constructed after the effective date of the final guidelines. Alliant Energy, IPL and WPL are currently unable to predict with certainty the impact of these guidelines on their financial condition and results of operations, but believe the expenditures to comply with these guidelines could be significant.
Land and Solid Waste -

(b) | IPL’s previous DAEC PPA that expired in February 2014 included minimum payments for IPL’s rights to electric generating capacity. IPL’s new DAEC PPA effective February 2014 does not contain minimum payments for electric generating capacity. |
| |
(c) | The PSCW order received for WPL’s retail fuel-related rate filing (2015 Test Year) contained an increase in retail electric fuel-related revenues in 2015. A portion of the approved increase was attributable to the impact of increased sales volumes approved in WPL’s retail electric base rate case for 2015 resulting in higher electric margin in 2015. |
| |
(d) | Higher transmission rider revenues were offset by higher electric transmission service expense. |
| |
(e) | Includes increases in temperature-normalized retail sales volumes at IPL and WPL for the three- and nine-month periods. Refer to “Sales Trends” below for further details. |
Forecast - Refer to Note 2 for discussion of WPL’s retail fuel-related rate cases for 2014 through 2016.

Sales Trends - Alliant Energy’s retail sales volumes increased 2% and decreased 1% for the three and nine months ended September 30, 20152016 compared to the same periods in 2014,2015, respectively. The three-month increase was primarily due to the impact of temperatures on residential and commercial sales due to the colderwarmer than normal temperatures and resulting lowerhigher air cooling demand in the third quarter of 2014.2016. The nine-month decrease was primarily due to the impact of temperatures on residential and commercialdecreases in IPL’s industrial sales due to the extremely cold temperatureslarge customer maintenance outages in 2016 and resulting higher heating demanddecreased retail sales related to IPL’s sale of its Minnesota electric distribution assets in July 2015, partially offset by an extra day of retail sales during the first quarter of 2014, partially offset by the warmer temperatures in the third quarter of 2015 compared2016 due to the same periodleap year, and increases in 2014.WPL’s commercial and industrial sales due to customer expansions.
IPL’s industrialAlliant Energy’s wholesale sales volumes decreased 3%increased 9% and 1%14% for the three and nine months ended September 30, 20152016 compared to the same periods in 2014, respectively,2015, respectively. These increases were primarily due to lower usage by industrial customers that have their own generation. WPL’s industrialadditional sales volumes increased 5% and 3% for the three and nine months ended September 30, 2015 compared to the same periods in 2014, respectively, primarily due to industrial customer expansions.
Alliant Energy’s wholesale sales volumes increased 12% and decreased 2% for the three and nine months ended September 30, 2015 compared to the same periods in 2014, respectively. The three-month increase was primarily due to afrom IPL’s new wholesale power supply agreement between IPL andwith Southern Minnesota Energy Cooperative. The new wholesale power supply agreement becameCooperative effective in July 2015 following the sale of IPL’s Minnesota electric distribution assets. The nine-month decrease was primarily due toAugust 1, 2015. These increases were partially offset by decreased sales to WPL’s partial-requirement wholesale customers that have contractual options to be served by WPL, other power supply sources or the MISO market, and the impact of the extremely cold temperatures during the first quarter of 2014. These decreases were partially offset by additional sales from IPL’s new wholesale power supply agreement with Southern Minnesota Energy Cooperative.market.
Alliant Energy’s bulk power and other revenuesales volumes changes were largely due to changes in sales in the wholesale energy markets operated by MISO and PJM.MISO. These changes are impacted by several factors, including the availability and dispatch of Alliant Energy’s EGUs and electricity demand within these wholesale energy markets. Changes in bulk power and other sales revenues were largely offset by changes in fuel-related costs, and therefore, did not have a significant impact on electric margins.
Forecast - Alliant Energy, IPL and WPL are currently expecting a modest increase in temperature-normalized retail electric sales in 2016 compared to 2015.
Electric Production Fuel and Energy PurchasesPurchased Power (Fuel-related) Cost RecoveriesExpenses - Fossil fuels, such as coalnatural gas and natural gas,coal, are burned to produce electricity at EGUs. The cost of fossil fuels used during each period is included in electric production fuel expense. Electricity is also purchased to meet customer demand and these costs are charged to energy purchasespurchased power expense.
Due to IPL’s cost recovery mechanisms for fuel-related costs,expenses, changes in fuel-related costsexpenses resulted in comparable changes in electric revenues and, therefore, did not have a significant impact on Alliant Energy’s and IPL’s electric margins. WPL’s cost recovery mechanism for wholesale fuel-related costsexpenses also provides for adjustments to its wholesale electric rates for changes in commodity costs, thereby mitigating impacts of changes to commodity costs on Alliant Energy’s and WPL’s electric margins.
WPL’s cost recovery mechanism for retail fuel-related costsexpenses supports deferrals of amounts that fall outside an approved bandwidth of plus or minus 2% of forecasted fuel-related costsexpenses determined by the PSCW each year. The difference between revenue collected and actual fuel-related costsexpenses incurred within the bandwidth increases or decreases Alliant Energy’s and WPL’s electric margins. WPL estimates the increaseincreases to electric margins from amounts within the bandwidth were approximately $2 million and $5 million for the three and nine months ended September 30, 2016, respectively. WPL estimates the increases to electric margins from amounts within the bandwidth were approximately $2 million and $6 million for the three and nine months ended September 30, 2015, respectively. WPL estimates the decrease to
Alliant Energy’s electric
margins from amounts within the bandwidth were approximately $0production fuel expense decreased $17 million and
$6$51 million for the three and nine months ended September 30,
2016 compared to the same periods in 2015, respectively. The decreases were primarily due to lower dispatch of IPL’s and WPL’s coal-fired EGUs during the three and nine months ended September 30, 2016 partially due to lower wholesale energy market prices and WPL’s retirement of Nelson Dewey Units 1 and 2 in December 2015. The decreases were also due to changes in the under-/over-collection of fuel-related expenses at IPL and lower natural gas prices. These items were partially offset by amortizations during the three and nine months ended September 30, 2016 of $8 million and $22 million, respectively, of under-recovered fuel-related expenses deferred by WPL in 2014,
respectively. Refer to Note 2and $4 million and $9 million of deferrals recorded during the three and nine months ended September 30, 2016, respectively, for discussion of an order received fromover-recovered fuel-related costs in 2016 that were outside the PSCW inapproved bandwidth for WPL. The amortizations are based upon a July 2015 PSCW order authorizing WPL to recover $28 million, including interest, from its retail electric customers beginning induring 2016 for deferred fuel-related costsexpenses incurred in 2014.
Alliant Energy’s electric production fuelpurchased power expense increased $36$17 million and $27$50 million for the three and nine months ended September 30, 2016 compared to the same periods in 2015, respectively. The increases wererespectively, primarily due to deferrals recorded during the three and nine months ended September 30, 2014 for fuel-related costs that were outside the approved bandwidth at WPL, and higherincreased volumes purchased resulting from lower dispatch of IPL’s and WPL’s coal-fired EGUs during the third quarterthree- and nine-month periods.
Electric Transmission Service Expense - Costs incurred each period for the transmission of 2015. The nine-month increase was partially offset byelectricity to meet the demands of IPL’s and WPL’s customers are included in electric transmission service expense. Electric transmission service expense is recovered from IPL’s Iowa retail electric customers through a transmission cost rider and from WPL’s retail electric customers through changes in the under-/over-collection of fuel-related costs at IPL.base rates determined during periodic rate proceedings, subject to an over/under escrow
treatment. IPL and WPL arrange transmission service for the majority of their respective wholesale electric customers. The wholesale portion of electric transmission service expense is allocated to and recovered from these wholesale customers based on a load ratio share computation. Due to IPL’s and WPL’s cost recovery mechanisms for electric transmission service expense, changes in electric transmission service expense resulted in comparable changes in electric revenues and, therefore, did not have a significant impact on Alliant Energy’s, energy purchasesIPL’s and WPL’s electric margins. Alliant Energy’s electric transmission service expense decreased $22increased $11 million and $40$29 million for the three and nine months ended September 30, 2016 compared to the same periods in 2015, respectively, primarily due to lower prices for electricity purchasedhigher electric transmission service rates billed by IPLITC, ATC and WPL from wholesale energy markets (primarily MISO) during the three- and nine-month periods and decreased volumes purchased. The decreased volumes purchased were due to higher dispatch of WPL’s coal-fired EGUs during the third quarter of 2015 and lower retail and wholesale electric sales during the nine-month period.MISO.
Utility Gas Margins - Gas margins are defined as gas operating revenues less cost of gas sold. Management believes that gas margins provide a more meaningful basis for evaluating utility operations than gas operating revenues since cost of gas sold is generally passed through to customers, and therefore, results in changes to gas operating revenues that are comparable to changes in cost of gas sold.

(a) | Approximately 50% of all margins earned from IPL’s sharing mechanism relating to optimizing gas capacity contracts flow through the purchased gas adjustment clause to reduce retail gas customer bills in Iowa. The remaining margins are retained by IPL and recorded in utility other revenues. Due to the extreme cold temperatures causing natural gas price fluctuations in the first quarter of 2014, margins were higher than normal for the nine months ended September 30, 2014. |

(a) | The July 2014 PSCW order for WPL’s 2015/2016 Test Period electric and gas base rate case authorized lower energy efficiency cost recovery amortizations for 2015.2015 and 2016. |
| |
(b) | Primarily resulting from the timing of maintenance projects at IPL’s and WPL’s EGUs. |
| |
(c) | Changes in IPL’s energy efficiency expense were offset by changes in electric and gas energy efficiency revenues. |
| |
(d) | Primarily due to an increase in retirement plans costs and other employee benefits-related costs. The increased retirement plan costs were largely due to decreases in discount rates and a change to the life expectancy assumption in 2014. |
| |
(e) | In the third quarter of 2015, Alliant Energy offered certain employees voluntary separation agreements of which approximately 2% of total Alliant Energy employees accepted. |
Forecast - Alliant Energy and WPL currently expect decreases in energy efficiency cost recovery amortizations at WPL in 2016 compared to 2015 as approved by the PSCW in a July 2014 order. Partially offsetting this expected decrease, Alliant Energy, IPL and WPL currently expect an increase in retirement plan costs in 2016 compared to 2015, resulting from lower than expected returns on retirement plan assets in 2015.

ForecastGas Transmission and Distribution Systems - In April 2016, the Pipeline and Hazardous Materials Safety Administration published proposed regulations to update safety requirements for gas transmission pipelines. The proposed regulations would add new assessment and repair criteria for gas pipelines, and require a systematic approach to verify a pipeline’s maximum allowable operating pressure. Alliant Energy, IPL and WPL currently anticipate final regulations will be issued in 2017. Given that the Pipeline and Hazardous Materials Safety Administration has not finalized these gas transmission regulations, Alliant Energy, IPL and WPL are currently unable to predict with certainty the impact of these regulations on their financial condition and results of operations.
IPL’s Clinton Natural Gas Pipeline - In August 2016, IPL received an order from the IUB authorizing IPL to construct, maintain, and operate a natural gas pipeline in Scott and Clinton Counties in Iowa, referred to as the Clinton pipeline. Construction is expected to be completed in the first quarter of 2017. Capital expenditures to construct the pipeline, excluding AFUDC, are currently estimated to be approximately $30 million to $35 million.
Generation Plans -
Natural Gas-Fired Generation -
WPL’s Construction of the Riverside Expansion - In May 2016, WPL received an order from the PSCW authorizing WPL to construct a natural gas-fired combined-cycle EGU in Beloit, Wisconsin, referred to as the Riverside expansion. In June 2016, WPL executed a design, engineering, procurement and construction contract for the Riverside expansion. After receiving the final necessary regulatory approvals and permits in the third quarter of 2016, WPL began constructing the Riverside expansion. WPL currently expects to place the Riverside expansion in service by early 2020.
In November 2016, various electric cooperatives notified WPL of their intent to exercise their options to acquire approximately 60 MW of the Riverside expansion while the EGU is being constructed. As a result of the various electric cooperatives funding a portion of the capital expenditures during construction, WPL’s estimated portion of capital expenditures is now expected to be approximately $640 million. The capital expenditures include costs to construct the EGU and a pipeline to supply natural gas to the EGU and exclude transmission network upgrades and AFUDC. Upon exercise of their options, the current wholesale power supply agreements with the various electric cooperatives will be extended by at least four years until 2026 with automatic continuation of such agreements unless terminated by either party, with a five-year notice requirement.
Pursuant to agreements WPL entered into with Wisconsin Public Service Corporation (WPSC) and Madison Gas and Electric Company (MGE) related to the Riverside expansion, WPL, WPSC and MGE filed a request with the PSCW seeking approval of amendments to the Columbia joint operating agreement. In October 2016, WPL received a decision from the PSCW approving such amendments, which allow WPSC and MGE to forgo certain capital expenditures at Columbia, resulting in WPL incurring these additional capital expenditures in exchange for a proportional increase in its ownership share of Columbia. Based upon the additional capital expenditures WPL currently expects to incur through June 1, 2020, WPL’s ownership interest in Columbia is expected to increase from 46.2% to 53.4%. WPL currently expects to file a request with FERC in the fourth quarter of 2016 for approval of these amendments to the Columbia joint operating agreement.
IPL’s Construction of Marshalltown - IPL began constructing Marshalltown in the second quarter of 2014 after receiving the final necessary regulatory approvals and permits. IPL executed an engineering, procurement and construction contract for Marshalltown after a competitive bidding process. In September 2016, Marshalltown’s engineering, procurement and construction contractor announced that costs to construct Marshalltown will exceed its expectations and that it expects to
seek compensation from vendors performing work on Marshalltown. IPL does not currently anticipate it will be responsible for these increased costs. Capital expenditures are currently estimated to be approximately $700 million to construct the EGU and a pipeline to supply natural gas to the EGU. The estimated capital expenditures exclude transmission network upgrades and AFUDC. IPL expects to place Marshalltown in service by the second quarter of 2017.
Wind Generation - The strategic plan includes the planned and potential addition of wind generation of up to 1,000 MW to Alliant Energy’s resources portfolio as follows. Estimated capital expenditures for the planned and potential wind generation projects for 2016 through 2020 are included in the “Renewable projects” line in the construction and acquisition expenditures table in “Liquidity and Capital Resources.”
IPL’s Expansion of Wind Generation - In October 2016, IPL and the Iowa Office of Consumer Advocate, among other customer groups, filed a settlement agreement with the IUB regarding the appropriate rate-making principles for up to 500 MW of additional wind generation at IPL. In October 2016, the IUB issued an order approving the settlement agreement, with limited modifications, and establishing rate-making principles, which IPL accepted, as follows:
Up to 500 MW of additional wind generation that qualifies for the full level of production tax credits, regardless of the location in Iowa, with a cost cap of $1,830/kilowatt, including AFUDC and transmission costs. Any costs incurred in excess of this $1,830/kilowatt cost cap are expected to be incorporated into rates if determined to be reasonable and prudent.
A depreciable life of the wind generation of 40 years, unless changed as a result of a contested case before the IUB.
An 11.0% return on common equity, with the exception of certain transmission facilities classified as intangible assets, which would earn the rate of return on common equity the IUB finds reasonable during a future rate case.
A return on common equity for the calculation of AFUDC during the construction period that is the greater of 10.0% or the percentage the IUB finds reasonable during IPL’s next rate case.
The application of double leverage is deferred until IPL’s next retail electric base rate case or other future proceeding.
Amortization over a 10-year period of IPL’s prudently incurred and unreimbursed costs, effective with IPL’s next retail electric base rate case, if IPL cancels the construction of the wind generation.
Withdrawal of IPL’s proposed renewable energy rider, which would have allowed IPL to commence recovery of the wind projects from its retail electric customers at the time the additional wind generation was placed in service.
IPL currently expects to add wind generation near its Whispering Willow - East wind farm, and is evaluating other siting options to build and operate the 500 MW of additional wind. IPL plans to commence the construction process in 2016, and as a result, be eligible for the full level of production tax credits from the electricity generated during the first 10 years of operation. IPL anticipates placing the 500 MW of additional wind generation in service in 2019 and 2020.
Franklin County Wind Farm - In addition to IPL’s expansion of wind generation discussed above, refer to Note 3 for discussion of IPL’s anticipated filing with FERC in the fourth quarter of 2016 requesting approval to transfer the 99 MW Franklin County wind farm assets from AEF to IPL in 2017.
IPL’s and WPL’s Potential Expansion of Wind Generation - In addition to IPL’s 500 MW expansion of wind generation and planned transfer of the 99 MW Franklin County wind farm to IPL in 2017 discussed above, IPL and WPL are exploring options to own and operate up to 400 MW of additional new wind generation in aggregate. The estimated capital expenditures included in “Liquidity and Capital Resources” assume this 400 MW of additional new wind generation will be equally allocated between IPL and WPL. The final amount and allocation of this potential expansion of wind generation for IPL and WPL is subject to change pending further evaluation.
Coal-Fired Generation -
Environmental Controls Projects - Refer to Note 3 for further discussion of a scrubber and baghouse project at Edgewater Unit 5, which was completed in July 2016.
RATE MATTERS
The rate matters summary included in the 2015 Form 10-K has not changed materially, except as described below.
WPL’s Wisconsin Retail Electric and Gas Rate Case (2017/2018 Test Period) - In May 2016, WPL filed a retail base rate case with the PSCW based on a forward-looking test period that includes 2017 and 2018. WPL’s filing was based on a stipulated agreement reached between PSCW staff, intervener groups and WPL. The filing requested approval for WPL to
implement a $13 million, or approximately 1%, increase in annual rates for WPL’s retail electric customers. The net requested increase for 2017 compared to WPL’s retail electric rate case for the 2015/2016 Test Period reflects a $65 million increase in base rates, partially offset by a $52 million reduction in fuel-related costs, using a preliminary estimate for 2017 fuel-related costs. Based on updated fuel-related cost information at the time of rate case hearings in September 2016, the current estimate of the net increase in annual rates for WPL’s retail electric customers is $17 million, consisting of the original $65 million increase in base rates, partially offset by a $48 million reduction in fuel-related costs. The filing also requested approval for WPL to implement a $9 million, or approximately 13%, increase in annual base rates for WPL’s retail gas customers. Any rate changes granted from this request are expected to be effective January 1, 2017 and extend through the end of 2018. The key drivers for the electric and gas base rate increases are recovery of the costs for environmental controls projects at Edgewater and Columbia, and investments in electric and gas distribution systems, including expansion of natural gas pipeline infrastructure. The filing also included utilization of amounts that WPL previously over-recovered from its customers for energy efficiency cost recovery and electric transmission cost recovery, as well as amounts deferred under the return on common equity sharing mechanism for the 2013/2014 Test Period to reduce the requested base rate increases. The fuel-related cost component of WPL’s retail electric rates for 2018 will be addressed in a separate filing, which is currently expected to be filed in the second or third quarter of 2017.
WPL’s May 2016 retail base rate filing included a return on common equity of 10.0% and continues a regulatory return on common equity sharing mechanism, whereby WPL must defer a portion of its earnings if its annual regulatory return on common equity exceeds 10.25% during the 2017 and 2018 Test Period. WPL must defer 50% of its excess earnings between 10.25% and 11.00%, and 100% of any excess earnings above 11.00%. The May 2016 filing also included the following key assumptions (Common Equity (CE); Long-term Debt (LD); Short-term Debt (SD); Weighted-average Cost of Capital (WACC)):

The May 2016 retail base rate filing also reflected the impact of the anticipated transfer of ATC from WPL to Alliant Energy or one of its subsidiaries by December 31, 2016 as discussed in “Other Future Considerations,” approved changes to depreciation rates pursuant to a September 2016 PSCW order, continued escrow treatment of transmission charges and application of AFUDC rates to 100% of the retail portion of the CWIP balances for the Riverside expansion. If WPL does not complete the anticipated transfer of ATC to Alliant Energy or one of its subsidiaries by December 31, 2016, WPL would expect to defer the revenue requirement impacts until such time the transfer occurs or until WPL’s next base rate case filing. The filing also assumed deferral of any potential changes in revenue requirement due to anticipated increases in WPL’s ownership share of Columbia resulting from the Riverside expansion agreements WPL previously entered into with neighboring utilities.
WPL currently expects a decision from the PSCW regarding this base rate filing in the fourth quarter of 2016.
WPL’s Retail Fuel-related Rate Filings - Refer to Note 2 for discussion of WPL’s retail fuel-related rate filings for the 2015 and 2016 Test Years.
WPL’s Depreciation Study - Refer to Note 1(c) for discussion of a September 2016 PSCW order approving updated depreciation rates for WPL effective January 1, 2017 as a result of a recently completed depreciation study. The September 2016 PSCW order also authorized WPL to recover the remaining net book value of Edgewater Unit 4 over a 10-year period beginning the later of the retirement date of the EGU or January 1, 2019.
IPL’s Tax Benefit Riders - Pursuant to a 2015 IUB order, IPL established tax benefit riders regulatory liabilities in 2014 to record higheradditional tax savings related to repair expenditures and cost of removal expenditures on partial dispositions that were previously capitalized to help offset the impact of future rate increases on IPL’s retail electric and gas customers. In November 2016, IPL filed a tariff with the IUB to facilitate refunds of approximately $75 million of the related tax benefits to IPL’s retail electric and gas customers in 2017. IPL currently expects a decision from the effect of rate-making on property related differencesIUB in 2016 compared to 2015.December 2016.
ENVIRONMENTAL MATTERS

Air Quality -
Ozone NAAQS Rule - The 2008 Ozone NAAQS Rule may require a reduction of NOx emissions in certain non-attainment areas designated by the EPA. Sheboygan County in Wisconsin is currently the only non-attainment area for the 2008 Ozone NAAQS Rule in Alliant Energy’s service territory. WPL operates Edgewater and the Sheboygan Falls Energy Center in Sheboygan County, Wisconsin. The compliance deadline for Sheboygan County to meet the 2008 Ozone NAAQS Rule was July 2016. Alliant Energy and WPL are currently in compliance with applicable requirements resulting from the 2008 Ozone NAAQS rule.

Franklin County Wind Farm - On a quarterly basis, Alliant Energy evaluates if there are any impairment indicators present related to the Franklin County wind farm. Based on an evaluation of the strategic options for the Franklin County wind farm performed in the third quarter of 2016, Alliant Energy concluded, as of September 30, 2016, it was probable the Franklin County wind farm will be transferred to IPL. As a result, Alliant Energy performed an impairment analysis of such assets in the third quarter of 2016. Refer to 2014Note 3 Form 10-K.for discussion of the impairment analysis, which resulted in non-cash, pre-tax asset valuation charges of $86 million recorded by Alliant Energy in the third quarter of 2016.
Other Future Considerations - AThe summary of other future considerations is included in the 20142015 Form 10-K and has not changed materially, from the items reported in the 2014 Form 10-K except as described below, and as discussed earlier in MDA and the Notes in Item 1 and “Risk Factors” in Item 1A.1.
Electric Transmission Service Expense -IPL and WPL currently receive substantially all their transmission services from ITC and ATC, respectively. Due to the formula rates used by ITC and ATC to charge their customers and possible future changes to these rates as discussed below, there is uncertainty regarding the long-term trends of IPL’s and WPL’s future electric transmission service expense. Alliant Energy, IPL and WPL currently anticipate future changes to their electric transmission service expense in 2016 as follows:
2017 Electric Transmission Service Expense - Alliant Energy, IPL and WPL currently estimate their total electric transmission service expense in 2017 will be lower than the comparable expense in 2016 by approximately $20 million, $15 million and $5 million, respectively. Such decreases are primarily due to expected lower return on equity resulting from the MISO transmission owner return on equity complaints. Alliant Energy’s, IPL’s and WPL’s estimated 2017 electric transmission service expense remains subject to change pending the IUB’s approval of IPL’s 2017 transmission rates and the PSCW’s final decision in WPL’s retail electric rate case for the 2017/2018 Test Period.
MISO Transmission Owner Return on Equity Complaints - A group of MISO cooperative and municipal utilities previously filed two complaints with FERC requesting a reduction to the base return on equity used by MISO transmission owners, including ITC and ATC. In September 2016, FERC issued an order on the first complaint and established a base return on equity of 10.32%, excluding any incentive adders granted by FERC, for the refund period from November 12, 2013 through February 11, 2015. In October 2016, in response to MISO’s and the MISO transmission owners’ request, FERC ordered the related refunds be issued by July 2017.
In June 2016, a FERC administrative law judge issued an initial decision regarding the second complaint and recommended a base return on equity of 9.70%, excluding any incentive adders granted by FERC, for the refund period from February 12, 2015 through May 11, 2016. A final decision from FERC on the second complaint is currently expected in the first half of 2017.
Alliant Energy and WPL have realized a cumulative $24 million of reductions in the amount of equity income from ATC as a result of the two complaints through September 30, 2016, including $9 million during the nine months ended September 30, 2016. These reductions are based upon a 10.32% base return on equity for the first complaint period and assume a 10.2% return on equity (9.70% base return on equity plus 50 basis point incentive adder approved in a previous FERC order) for the second complaint period and thereafter.
Attachment “O” Rates - The annual transmission service rates that ITC or ATC charges their customers are calculated each calendar year using a FERC-approved cost of service formula rate referred to as Attachment “O.” Because Attachment “O” is a FERC-approved formula rate, ITC and ATC can implement new rates each calendar year without filing a request with FERC. However, new rates are subject to challenge by either FERC or customers. If the rates proposed by ITC or ATC are determined by FERC to be unjust or unreasonable or another mechanism is determined by FERC to be just and reasonable, ITC’s or ATC’s rates would change accordingly.
2016 Rates Charged by ITC to IPL - In August 2015, ITC filed with MISO the Attachment “O” rate it proposes to charge its customers in 2016 for electric transmission services. The proposed rate was based on ITC’s estimated net revenue requirement for 2016 as well as a true-up adjustment credit related to amounts that ITC over-recovered from its customers in 2014. Amounts billed under the 2016 Attachment “O” rate are currently expected to be approximately 6% higher than the amounts ITC is charging its customers in 2015.
20162017 Rates Charged by ATC to WPL - In September 2015,October 2016, ATC shared with its customers the Attachment “O” rate it proposes to charge them in 20162017 for electric transmission services. The proposed rate was based on ATC’s estimated net revenue requirement for 20162017 as well as a true-up adjustment credit related to amounts that ATC over-recovered from its customers in 2014.2015 and expects to over-recover from its customers in 2016. Amounts billed under the 20162017 Attachment “O” rate are currently expected to be approximately 7% higher5% lower than the amounts ATC is charging its customers in 2015.2016. The proposed rate for 2017 reflects a 10.82% return on equity for the impact of FERC’s September 2016 order to lower the base return on equity for MISO transmission owners to 10.32% discussed above, plus a 50 basis point incentive return on equity adder based on ATC’s participation in MISO.
MISO Transmission Charges Billed2017 Rates Charged by ITC to IPL and WPL - In October 2016, ITC filed with MISO tariffs billedthe Attachment “O” rate it proposes to IPL and WPL include costscharge its customers in 2017 for electric transmission services. The proposed rate was based on ITC’s estimated net revenue requirement for 2017 as well as a true-up adjustment related to various shared transmission projects including Multi-value Projects. Multi-value Projects include new large scale transmission projectsamounts that enableITC under-recovered from its customers in 2015. Amounts billed under the reliable and economic delivery of energy in support of documented energy policy mandates or provide economic value across multiple pricing zones within MISO. Multi-value Project costs2017 Attachment “O” rate are socialized across the entire MISO footprint based on energy usage of each MISO participant. MISO tariffs billed to IPL and WPL also include costs related to other shared transmission projects, including projects designed to reduce market congestion, to provide interconnection to the transmission grid for new generation, and to ensure compliance with applicable reliability standards. The costs of these projects are primarily allocated to MISO participants in a way that is commensurate with the benefit to the participants’ pricing zone. The MISO transmission charges billed to IPL and WPL are expected to increase in the future due to the number of shared transmission projectscurrently expected to be completedapproximately 4% higher than the amounts ITC is charging its customers in 2016. The proposed rate for 2017 reflects an 11.32% return on equity for the impact of FERC’s September 2016 order to lower the base return on equity for MISO region.transmission owners to 10.32% discussed above, plus a 50 basis point incentive return on equity adder based on ITC’s participation in MISO, as well as a 50 basis point incentive return on equity adder for ITC being an independent transmission company. The proposed rate for 2017 also reflects the impacts of bonus tax depreciation deductions for 2015, 2016 and 2017 in response to FERC’s March 2016 order discussed below.
2016 Electric Transmission Service ExpenseITC Bonus Tax Depreciation Deductions - In December 2015, IPL filed a complaint with FERC regarding ITC’s Attachment “O” rate pursuant to FERC-approved Attachment “O” protocols. IPL’s complaint alleged that ITC acted imprudently by failing to take advantage of tax savings benefits available through bonus tax depreciation deductions, which results in higher Attachment “O” rates being billed by ITC to IPL. In March 2016, FERC issued an order concluding that ITC acted imprudently by failing to take advantage of tax savings benefits available through bonus tax depreciation deductions. The FERC order requires ITC to recalculate its Attachment “O” rate effective January 1, 2015 to simulate taking bonus tax depreciation deductions for 2015. In April 2016, ITC filed a request for rehearing of FERC’s March 2016 order. IPL subsequently filed a response to ITC’s request for rehearing, requesting that FERC require ITC to also take bonus tax depreciation deductions for 2012 through 2014. In June 2016, FERC issued an order rejecting ITC’s and IPL’s requests. If ITC does not take advantage of bonus tax depreciation deductions in 2016 or in future years, IPL retains the right under Attachment “O” protocols to challenge ITC’s decision if IPL deems that decision to be imprudent. Alliant Energy and IPL and WPLare currently estimate their total electric transmission service expense in 2016 will be higher thanreviewing ITC’s estimated impacts through the comparable expense in 2015 by approximately $35 million, $25 million and $10 million, respectively, as a result of the items discussed above. A significant portion of the increaseFERC-approved Attachment “O” protocols.
Electric Transmission Cost Recovery - Any changes in IPL’s electric transmission service expense iscosts billed by ITC to IPL are expected to be offset with increases inpassed on to IPL’s Iowa retail electric revenuescustomers through the transmission cost recovery rider. AnyThe difference between WPL’s actual electric transmission service expense incurred and amounts collected from customers as electric revenues in 2016 will2017 is expected to be recorded as electric transmission service expense with an offsetting amount recorded to a regulatory asset or regulatory liability due to the escrow treatment authorized forproposed by WPL in its 2015/20162017/2018 Test Period retail electric rate case. Based on IPL’s and WPL’s electric transmission cost recovery mechanisms, IPL and WPL currently do not expect that any changes to electric transmission service costs billed by ITC and ATC will have a material impact on their financial condition and results of operations. IPL and WPL could have a material impact on their cash flows depending on the final timing of refunds resulting from the MISO return on equity complaints, and the subsequent timing of the refunds being credited to their customers.
MISO Transmission Owner Return on Equity Complaints - In 2013, a group of MISO industrial customer organizations filed a complaint with FERC requesting to reduce the base return on equity used by MISO transmission owners, including ITC and ATC, among other items. ITC’s and ATC’s current authorized return on equity is 12.38% and 12.2%, respectively. In 2014, FERC issued an order on the complaint, established hearing and settlement procedures on the return on equity component of the complaint, and established an effective refund date of November 12, 2013. Various parties to the proceeding have filed testimony with FERC identifying base return on equity ranges with stated midpoints between 8.58% and 11.39%, excluding any incentive adders granted by FERC. A final decision from FERC on this complaint is currently expected in 2016.
In June 2015, FERC issued an order on an additional complaint filed with FERC by a group of MISO cooperative and municipal utilities requesting to reduce the base return on equity used by MISO transmission owners, including ITC and ATC, to 8.67%. FERC’s June 2015 order established hearing procedures and an effective refund date of February 12, 2015. A final decision from FERC on this complaint is currently expected in 2017.
Based on other recent FERC return on equity decisions,WPL’s Future Transfer of Investment in ATC - In June 2016, WPL received an order from the PSCW requiring WPL to transfer its investment in ATC to Alliant Energy IPLor an Alliant Energy subsidiary by December 31, 2022. In addition, WPL is required to obtain PSCW approval prior to transferring any additional capital or assets to ATC. WPL is currently evaluating the impacts of the June 2016 PSCW order on its results of operations and financial condition. Subsequent to WPL currently anticipate FERC’s decision on the MISO transmission owner complaints will reduce transmission owners’ current authorized return ontransferring its investment in ATC, future contributions to, and equity which is expected to reduce electric transmission service expense costs billed by ITC and ATC to their customers and result in lower equity incomeearnings and dividends from, the investment in ATC would occur at the entity to which the investment in ATC was transferred and would not be reflected in WPL’s consolidated financial statements. As a result, WPL’s earnings and cash flows from operations are expected to decrease subsequent to the future.transfer. This transfer is not expected to impact Alliant Energy and WPL have realized $7 million of reductions in the amount of equity income from ATC for the period from November 12, 2013 through September 30, 2015, including $4 million of reductions recorded during the nine months ended September 30, 2015. These reductions assume the final return on equity awarded to ATC will be 11.5% (including a 50 basis point incentive adder). Alliant Energy and WPL currently estimate each 25 basis point reduction in ATC’s authorized return on equity would reduce their annual pre-tax equity income from ATC by approximately $1 million.Energy’s consolidated financial statements.
ITC Request for Equity Adder - In January 2015, ITC requested approval from FERC to implement a 100 basis point incentive adder to its base return on equity for being an independent transmission company. In March 2015, FERC issued an order granting a 50 basis point incentive adder to ITC’s base return on equity for being an independent transmission company. The implementation of the adder will be retroactively applied back to April 2015 after resolution of a MISO transmission owner return on equity complaint filed in 2013 by a group of MISO industrial customer organizations. Alliant Energy and IPL are currently unable to determine any resulting changes to future electric transmission service charges pending a decision by FERC on the 2013 complaint. Alliant Energy and IPL currently expect to pass on the retail portion of any changes in electric transmission service costs billed by ITC to IPL to IPL’s retail electric customers through the transmission cost recovery rider.

The KEESA amendment provides that if any portion of the payments under the KEESA or any other agreement with an executive officer would constitute an excess parachute payment subject to an excise tax under the Internal Revenue Code, then those payments will be reduced to $1 less than the maximum amount that the executive officer could receive without becoming subject to the excise tax, provided that this reduction will not apply if the fully calculated payment would result in a greater net after-tax amount payable to the executive officer. The KEESA of the CEO already includes this provision. Alliant Energy cannot currently determine the benefits, if any, to be paid in the future to its executive officers under the KEESA. The foregoing description of the KEESA amendment is qualified in its entirety by reference to the KEESA amendment, which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.
