Section 7 - Regulation FD

Item 7.01 Regulation FD Disclosure

Section 8 - Other Events

Item 8.01 Other Events

On September 19, 2012 PPL Montana, LLC (“PPL Montana”), an indirect wholly owned subsidiary of PPL Energy Supply, LLC (“PPL Energy Supply”) and PPL Corporation (“PPL”), issued a press release announcing PPL Montana’s current plan to place its 154 megawatt coal-fired J.E. Corette generating plant into long-term reserve status beginning in April 2015. A copy of the press release is furnished herewith as Exhibit 99.1.

The current carrying value of the plant is approximately $67 million. It is reasonably possible that an impairment charge could be recorded for the third quarter of 2012 or in future periods. Any impairment related to the plant is not currently expected to be material to PPL and would be treated as a special item for purposes of calculating earnings from ongoing operations.  PPL Energy Supply will separately report if any future determination is made that a material charge is required to be taken in connection with the suspended operation of the Corette plant.

Section 9 - Financial Statements and Exhibits

Item 9.01 Financial Statements and Exhibits

(d)	Exhibits
	99.1 -	Press release dated September 19, 2012 of PPL Montana, LLC.

Statements contained in this Current Report on Form 8-K, including statements with respect to future earnings and generation operations are “forward-looking statements” within the meaning of the federal securities laws. Although PPL and PPL Energy Supply believe the expectations and assumptions reflected in these forward-looking statements are reasonable, these statements are subject to a number of risks and uncertainties, and actual results may differ materially from the results discussed in the statements. Among the important factors that could cause actual results to differ materially from the forward-looking statements are: market demand and prices for energy, capacity and fuel; competition in power markets; the effect of any business or industry restructuring; the profitability and liquidity of PPL Corporation and its subsidiaries; 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 or business acquisitions and dispositions, 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 and PPL Energy Supply's Form 10-K and other reports on file with the Securities and Exchange Commission.

“Earnings from ongoing operations” should not be considered as an alternative to reported earnings, or net income attributable to PPL, 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 financial measure, is also useful and meaningful to investors because it provides management’s view of PPL’s fundamental earnings performance as another criterion in making 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.

“Earnings from ongoing operations” is adjusted for the impact of special items. Special items include:

·   Energy-related economic activity.

·   Foreign currency-related economic hedges.

·   Gains and losses on sales of assets not in the ordinary course of business.

·   Impairment charges (including impairments of securities in the company’s nuclear decommissioning trust funds).

·   Workforce reduction and other restructuring impacts.

·   Acquisition-related adjustments.

·   Other charges or credits that are, in management’s view, not reflective of the company’s ongoing operations.

PPL Montana Announces Plan to Place J.E. Corette Power Plant in Reserve Status

BILLINGS, Mont. (Sept. 19, 2012) — The effects of pending Environmental Protection Agency regulations combined with economic factors have resulted in a decision announced Wednesday (9/19) by PPL Montana to place the J.E. Corette power plant in Billings into long-term reserve status beginning in April 2015.

“Our detailed analysis has shown that to meet the emission reductions required by EPA’s Mercury and Air Toxics Standards, we would need to invest $38 million in the Corette plant. We simply cannot justify that level of spending in the current wholesale power market in the Northwest,” said Pete Simonich, PPL Montana vice president and chief operating officer.

Wholesale power prices have been depressed in the Northwest because of declining electricity use and an abundance of new wind energy projects subsidized by federal production tax credits.

PPL Montana plans to operate the Corette plant until requirements of the Mercury and Air Toxics Standard take effect in April 2015. The plant will then be placed in reserve status, commonly called “mothballing.”

Mothballing the Corette plant, rather than shutting it down permanently, gives PPL Montana the opportunity to resume operations at some point if conditions change.

The 154-megawatt power plant, which uses low-sulfur coal from the Powder River Basin, has 35 full-time employees. The plant began operation in 1968.

“We respect and appreciate the skills and dedication of the plant’s employees in meeting the many operational, environmental and economic challenges they have faced. We expect no immediate change in the number of jobs at the plant, and we pledge to work with plant employees to ensure that the transition period over the next two and a half years is as smooth as possible,” Simonich said.

PPL Montana also operates the Colstrip power plant, which is not affected by the Corette decision and is better positioned to meet the requirements of the Mercury and Air Toxics Standards.

PPL Montana owns more than 1,200 megawatts of coal-fired and hydroelectric generating capacity across Montana and has offices in Billings, Butte and Helena. PPL Montana and its 500 employees support educational, environmental and economic development programs across the state. PPL EnergyPlus operates a trading floor in Butte that markets and sells power for PPL Montana in wholesale and retail energy markets throughout the western United States. PPL Montana and PPL EnergyPlus are subsidiaries of PPL Corporation (NYSE: PPL). More information about PPL Montana is available at www.pplmontana.com.
