FOR IMMEDIATE RELEASE

Allegheny Energy Reports Solid Third Quarter 2007 Results

GREENSBURG, Pa., October 25, 2007 -- Allegheny Energy, Inc. (NYSE: AYE) today reported financial results for the three months and nine months ending September 30, 2007.


	$ millions		Per Share
Three Months Ended September 30	2007	2006	2007	2006
Consolidated net income-GAAP	$115.0	$110.2	$0.67	$0.65
Adjusted net income	115.0	94.0	0.67	0.56

Nine Months Ended September 30
Consolidated net income-GAAP	$301.8	$254.7	$1.78	$1.51
Adjusted net income	301.8	246.0	1.78	1.46

There were no adjustments to net income for the third quarter of 2007. The adjusted results for the third quarter of 2006 exclude a $16.7 million (after-tax) benefit associated with a change in Pennsylvania tax law, and a $0.5 million (after-tax) loss from discontinued operations.

“Our solid financial performance continued in the third quarter,” said Paul J. Evanson, Chairman, President and Chief Executive Officer of Allegheny Energy. “Favorable market prices, higher generation rates and increased retail sales were key drivers of our strong results.

“Having achieved an investment grade credit rating, we’ve reinstated the common stock dividend, our first payout to shareholders in more than five years,” Evanson said.

Third Quarter Consolidated Results

Net income for the third quarter of 2007 increased by $21.0 million compared with adjusted net income for the same period in 2006. Key factors contributing to the improved results include:

•	Operating revenues increased by $30.0 million compared to the third quarter of 2006, reflecting higher market prices, higher generation rates in Pennsylvania and increased retail sales, partially offset by lower generation output.
•	Fuel expense increased by $14.5 million, largely due to higher coal prices.
•	Purchased power and transmission expense decreased by $8.1 million, primarily due to the expiration of a power sale agreement associated with the former Ohio territory, partially offset by higher costs to purchase power to serve Virginia customers
•	Operations and maintenance expense increased by $4.1 million, reflecting a contingent consulting fee.
•	Other income increased by $7.0 million, reflecting a gain related to the company’s La Paz, Arizona, real estate.
•	Interest expense decreased by $6.8 million.
•	Income taxes increased by $9.6 million compared to adjusted income tax expense for 2006, largely due to higher pre-tax income.

EBITDA for the third quarter of 2007 was $308.6 million, an increase of $22.3 million compared to the same quarter of the prior year. EBITDA is a non-GAAP financial measure. Details on the calculation of EBITDA and a reconciliation of EBITDA to net income are attached to this release.

Third Quarter Segment Results

Three Months Ended September 30 ($ millions)
	2007	2006
Generation and Marketing:
Net income – GAAP	$102.2	$66.4
Adjusted net income	102.2	50.2

Delivery and Services:
Net income – GAAP	$12.8	$43.8
Adjusted net income	12.8	43.8

There were no adjustments in either segment for the third quarter of 2007. For the third quarter of 2006, the Generation and Marketing segment’s adjusted net income excludes a $16.7 million (after-tax) benefit associated with a change in Pennsylvania tax law and a $0.5 million (after-tax) loss on discontinued operations related to the Gleason generating facility.

Generation and Marketing: Net income for the quarter increased $52.0 million compared to adjusted net income for the same period a year earlier. Key factors contributing to the improved results were higher market prices, higher generation rates in Pennsylvania and a gain from the company’s La Paz, Arizona, real estate. These benefits were partially offset by higher fuel costs and a reduction in power plant output in the third quarter of 2007 compared to the same period a year earlier.

Delivery and Services: Net income for the quarter decreased by $31.0 million compared to adjusted net income for the same quarter of the prior year. Results were negatively impacted by the increased cost of purchasing power at market rates to serve customers in Virginia and a rate decrease in West Virginia. Kilowatt-hour sales, however, increased by 1.3 percent, reflecting warmer weather and customer growth.

Discontinued Operations: There were no results from discontinued operations for the third quarter of 2007, compared to a $0.5 million (after-tax) loss from discontinued operations for the same period of the prior year related to the Gleason generating facility, which Allegheny sold in the fourth quarter of 2006.

Nine-Month Segment Results

Nine Months Ended September 30 ($ millions)
	2007	2006
Generation and Marketing:
Net income – GAAP	$210.1	$141.2
Adjusted net income	210.1	131.5

Delivery and Services:
Net income – GAAP	$91.7	$113.5
Adjusted net income	91.7	114.5

There were no adjustments in either segment for the first nine months of 2007. Adjusted net income for the same period of 2006 excludes items described in the attached reconciliation of non-GAAP financial measures. Adjusted net income is a non-GAAP financial measure.

Reconciliation of Non-GAAP Financial Measures

This news release and the attached table include non-GAAP financial measures as defined in the Securities and Exchange Commission’s Regulation G. Where noted, we present financial information on an adjusted basis to exclude the effect of certain items as described herein. By presenting adjusted results, management intends to provide investors with a more complete understanding of the core results and underlying trends from which to consider past performance and prospects for the future. We also present EBITDA as an additional measure of our operating performance.

Users of this financial information should consider the types of events and transactions for which adjustments have been made. Neither the adjusted information nor EBITDA should be considered in isolation or viewed as substitutes for or superior to net income or other data prepared in accordance with GAAP as measures of our operating performance or liquidity. In addition, neither the adjusted information nor EBITDA is necessarily comparable to similarly titled measures provided by other companies.

Pursuant to the requirements of Regulation G, we have attached tables that reconcile non-GAAP financial measures, including those presented in this release, to the most directly comparable GAAP measures.

Allegheny Energy will discuss these results in a live Internet broadcast at 8:30 a.m. Eastern Daylight Time on Friday, October 26, 2007. To listen to the broadcast, visit www.alleghenyenergy.com. A taped replay will be available after the live broadcast.
