New Jersey portion of the line to be built  by PSEG.  • Project needed for reliability and is part of  PJM’s Regional Transmission Expansion Program (RTEP)  • Expected to be completed in May 2012  • Cost of PPL’s portion of the line is  estimated at $500 million  • PPL earns incentive rates for RTEP  project  – ROE adder for membership in an  RTO 0.50%  – ROE adder for RTEP projects 1.25%  – CWIP in rate base  – Recovery of costs if abandoned  • Formula rate mechanism for transmission  18

 UK Electricity Distribution Regulation  • Electricity and natural gas supply and distribution are regulated by the UK’s Office of  Gas and Electricity Markets.  • Electricity distribution revenues are set every five years through a Distribution Price  Control Review (DPCR) process.  – Price control is based on a forward looking assessment of income sufficient to finance an  efficient business.  – Revenues must cover operating and capital costs at an efficient level for the service territory.  • Efficiency is determined through a detailed comparable analysis of all UK electricity  distribution companies.  – Typically, the DPCR results in a one-time price reduction followed by annual adjustments for  inflation less an efficiency factor.  • An incentive / penalty arrangement exists for reliability and customer service levels.  • The revenue that a company can earn in each of the five years is the sum of:  – The Regulator’s view of efficient operating costs,  – A return on the value of Regulated Asset Base (“RAB”), and  – A return of capital being the depreciation of the RAB.  • The DPCR is currently in process with the next five-year period beginning April 1,  2010.  19

 Forward-Looking Information Statement  A-14  Statements contained in this presentation, including statements with respect to future earnings, energy prices, margins,  sales and supply, marketing performance, hedging, growth, revenues, expenses, rates, regulation, cash flows, credit  profile, financing, dividends, business disposition, corporate strategy, capital additions and expenditures, and generating  capacity and performance, are “forward-looking statements” within the meaning of the federal securities laws. Although  PPL Corporation believes that the expectations and assumptions reflected in these forward-looking statements are  reasonable, these statements involve a number of risks and uncertainties, and actual results may differ materially from the  results discussed in the statements. The following are among the important factors that could cause actual results to differ  materially from the forward-looking statements: market demand and prices for energy, capacity and fuel; volatility in  financial or commodities markets; weather conditions affecting customer energy usage and operating costs; competition in  power markets; the effect of any business or industry restructuring; the profitability and liquidity of PPL Corporation and its  subsidiaries; new accounting requirements or new interpretations or applications of existing requirements; operating  performance of plants and other facilities; environmental conditions and requirements and the related costs of compliance,  including environmental capital expenditures and emission allowance and other expenses; system conditions and  operating costs; development of new projects, markets and technologies; performance of new ventures; asset acquisitions  and dispositions; any impact of hurricanes or other severe weather on our business, including any impact on fuel prices;  receipt of necessary government permits, approvals and rate relief; capital market conditions and decisions regarding  capital structure; the impact of state, federal or foreign investigations applicable to PPL Corporation and its subsidiaries;  the outcome of litigation against PPL Corporation and its subsidiaries; stock price performance; the market prices of equity  securities and the impact on pension income and resultant cash funding requirements for defined benefit pension plans;  the securities and credit ratings of PPL Corporation and its subsidiaries; political, regulatory or economic conditions in  states, regions or countries where PPL Corporation or its subsidiaries conduct business, including any potential effects of  threatened or actual terrorism or war or other hostilities; foreign exchange rates; new state, federal or foreign legislation,  including new tax legislation; and the commitments and liabilities of PPL Corporation and its subsidiaries. Any such  forward-looking statements should be considered in light of such important factors and in conjunction with PPL  Corporation’s Form 10-K and other reports on file with the Securities and Exchange Commission.

 “Earnings from ongoing operations” excludes the impact of special items. Special items include charges, credits or gains that are unusual or  nonrecurring. Special items also include the mark-to-market impact of energy-related, non-trading economic hedges and impairments of securities in  PPL’s nuclear decommissioning trust funds. These energy-related, non-trading economic hedges are used to hedge a portion of the economic value of  PPL’s generation assets and PPL’s load-following and retail activities. This economic value is subject to changes in fair value due to market price  volatility of the input and output commodities (e.g., coal and power). The mark-to-market impact of these hedges is economically neutral to the  company because the mark-to-market gains or losses on the energy hedges will reverse as the hedging contracts settle in the future. Earnings from  ongoing operations should not be considered as an alternative to reported earnings, or net income attributable to PPL Corporation, which is an indicator  of operating performance determined in accordance with generally accepted accounting principles (GAAP). PPL believes that earnings from ongoing  operations, although a non-GAAP measure, is also useful and meaningful to investors because it provides them with PPL’s underlying earnings  performance as another criterion in making their investment decisions. PPL’s management also uses earnings from ongoing operations in measuring  certain corporate performance goals. Other companies may use different measures to present financial performance.  The presentation under the heading “Supply Segment Open EBITDA” is intended to provide information about PPL’s Supply segment generation and  marketing activities. PPL believes that these measures are useful to both management and investors’ evaluation of PPL’s Supply segment. The  information presented, however, is not intended to be nor should it be relied upon as a projection of expected actual earnings performance.  Certain information presented under the heading “Supply Segment Open EBITDA” contains non-GAAP financial measurements. “Open EBITDA”,  “Unhedged Gross Margin” and “Expected Margin” are non-GAAP measures, applied to a single business segment and should not be considered an  alternative to “Net Income”, “Operating Income” or other measures determined in accordance with GAAP.  Unhedged Gross Margin is calculated based on estimated sales of electricity and relevant market prices at an identified point in time for energy and  capacity as well as fuel and other variable costs as related to PPL’s Supply segment generation and marketing activities. Open EBITDA is equal to  Unhedged Gross Margin less forecasted O&M expense for PPL’s Supply segment. Other companies may calculate Unhedged Gross Margin and Open  EBITDA differently.  Expected Margin is Unhedged Gross Margin plus the above or (below) market value of power and fuel hedges, calculated at an identified point in time.  PPL believes Expected Margin is useful to both management and investors as an indication of the scope and dimension of the potential financial  performance of PPL’s generation and marketing activities. Other companies may calculate Expected Margin differently.  “Free cash flow before dividends” is derived by deducting capital expenditures and other investing activities-net, as well as the repayment of transition  bonds, from cash flow from operations. Free cash flow before dividends should not be considered as an alternative to cash flow from operations, which  is determined in accordance with GAAP. PPL believes that free cash flow before dividends, although a non-GAAP measure, is an important measure to  both management and investors since it is an indicator of the company’s ability to sustain operations and growth without additional outside financing  beyond the requirement to fund maturing debt obligations. Other companies may calculate free cash flow before dividends in a different manner.  Definitions of Non-GAAP Financial Measures  A-15
