FOR IMMEDIATE RELEASE

Allegheny Energy Reports Strong Second Quarter 2007 Results

GREENSBURG, Pa., July 26, 2007 -- Allegheny Energy, Inc. (NYSE: AYE) today reported financial results for the three months and six months ending June 30, 2007.

	$ millions		Per Share
Three Months Ended June 30	2007	2006	2007	2006
Consolidated net income-GAAP	$77.0	$31.1	$0.45	$0.18
Adjusted net income	77.0	37.8	0.45	0.22

Six Months Ended June 30
Consolidated net income-GAAP	$186.8	$144.5	$1.10	$0.86
Adjusted net income	186.8	152.0	1.10	0.90

There were no adjustments to net income for the second quarter of 2007. The adjusted results for the second quarter of 2006 exclude a $9.5 million (pre-tax) charge for the write-off of prior deferred financing costs, and a $0.9 million (after-tax) loss from discontinued operations.

“We achieved strong financial results for the second quarter,” said Paul J. Evanson, Chairman, President and Chief Executive Officer of Allegheny Energy. “Favorable generation prices, higher retail delivery sales and lower corporate expenses were the key contributors. In addition, we achieved two important goals this quarter, reaching an investment grade credit rating and gaining PJM’s approval of our second transmission project. Despite two disappointing regulatory decisions, we expect solid earnings growth for 2007 and beyond.”

Second Quarter Consolidated Results

Net income for the second quarter of 2007 increased by $39.2 million compared with adjusted net income for the same period in 2006. Key factors contributing to the results include:

•	Operating revenues increased by $104.2 million compared to the second quarter of 2006, reflecting higher market prices, higher generation rates in Pennsylvania, increased generation output and increased retail sales.

•	Fuel expense increased by $39.6 million due to higher coal prices and increased gas consumption.

•	Purchased power and transmission expense increased by $11.3 million primarily due to PURPA power purchase costs.

•	Operations and maintenance expense decreased by $9.8 million, reflecting lower costs for outside services and claims reserves.

•	Interest expense decreased by $4.0 million.

•	Income taxes increased by $32.5 million largely due to higher pre-tax income.

EBITDA for the second quarter of 2007 was $263.8 million, an increase of $70.1 million compared to adjusted EBITDA for the same quarter of the prior year. EBITDA and adjusted EBITDA are non-GAAP financial measures. Details on the calculation of these figures and a reconciliation of EBITDA to net income are attached to this release.

Second Quarter Segment Results

Three Months Ended June 30 ($ millions)
	2007	2006
Generation and Marketing:
Net income – GAAP	$43.6	$7.8
Adjusted net income	43.6	13.5

Delivery and Services:
Net income – GAAP	$33.4	$23.3
Adjusted net income	33.4	24.3

There were no adjustments in either segment for the second quarter of 2007. For the second quarter of 2006, both segments’ adjusted net income excludes the write-off of prior deferred financing costs previously mentioned, and the Generation and Marketing segment’s adjusted net income also excludes results of discontinued operations.

Generation and Marketing: Net income for the quarter increased $30.1 million compared to adjusted net income for the same period a year earlier. Key factors contributing to the improved results were higher Pennsylvania generation rates, higher market prices and a 5 percent increase in kilowatt-hours generated, partially offset by higher fuel costs. Income taxes increased due to higher pre-tax income and a higher effective tax rate.

Delivery and Services: Net income for the quarter increased by $9.1 million compared to adjusted net income for the same quarter of the prior year. Kilowatt-hour sales increased by 6 percent, reflecting customer growth, increased usage per customer and favorable weather. The related revenue increase was partly offset by increased costs of purchasing power to meet demand and a base rate decrease in West Virginia.

Discontinued Operations: Discontinued operations had no impact on results for the second quarter of 2007, compared to a $0.9 million (after-tax) loss for the same period of the prior year. The 2006 loss relates to the Gleason generating facility, which Allegheny sold in the fourth quarter of 2006.

Six Months Ended June 30 ($ millions)
	2007	2006
Generation and Marketing:
Net income – GAAP	$107.9	$74.8
Adjusted net income	107.9	81.3

Delivery and Services:
Net income – GAAP	$78.9	$69.7
Adjusted net income	78.9	70.7

There were no adjustments to net income for the first six 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.

Investor Conference Call

Allegheny Energy will discuss these results in a live Internet broadcast at 8:30 a.m. Eastern Daylight Time on Friday, July 27, 2007. To listen to the broadcast, visit www.alleghenyenergy.com. A taped replay will be available after the live broadcast.
