���������ֳ�-New York-June 17, 2003: ���������ֳ� has upgraded the senior unsecured ratings of Allegheny Energy Inc. (AYE) and its utility subsidiaries as follows: AYE to 'BB' from 'B+'; West Penn Power Company (WPP) to 'BBB-' from 'BB+', Potomac Edison Company (PE) to 'BBB-' from 'BB'; and Monongahela Power Company (MP) to 'BBB-' from 'BB'. ���������ֳ� has also assigned a 'BB' rating to AYE's $330 million unsecured bank facility maturing 2005. The ratings are also placed on Rating Watch Evolving. A list of the affected ratings is listed below.

AYE's ratings are supported by stable dividend stream from its regulated subsidiaries MP, WPP and PE. AYE has low parent leverage and has suspended dividend payments to its common shareholders. As a result, AYE's standalone liquidity is adequately supported by dividend distributions received from its regulated subsidiaries. AYE's ratings also reflect the company's exposure to its unregulated subsidiary Allegheny Energy Supply Company LLC (AE Supply, senior secured debt rated 'BB' by ���������ֳ�), which is currently facing financial stress. (For more details on ���������ֳ�'s latest rating actions on AE Supply and affiliates, please refer to today's press release, '���������ֳ� Rates AE Supply Secured Bank Facilities; Affirms Senior At 'B'', available on the ���������ֳ� web site at ''.)

The upgrade of AYE's senior unsecured debt is triggered by a thorough analysis of the recovery prospects of the company based on the strong net equity value of its three regulated utilities. ���������ֳ� estimates that the net equity value of AYE's utilities covers AYE's current debt and potential exposure to AE Supply sufficiently. Currently AYE has issued about $200 million of guarantees on behalf of Allegheny.

The upgrade of AYE permits the corresponding upgrade of its regulated utilities, whose ratings are currently constrained by those of its parent. WPP, PE, and MP all have substantially better standalone credit profiles than indicated by their current constrained ratings. The rating constraint of the utilities by AYE's rating reflects the utilities' moderate degree of insulation from the parent. Since WPP, PE, and MP are not entirely insulated from the credit risk of their parent, their senior unsecured ratings are two notches above AYE's senior unsecured ratings.

The Rating Watch Evolving status reflects the current status of AE Supply, whose ratings are contingent upon the outcome of several upcoming events. The AYE group has yet to complete its restatements of quarterly financial results for 2002 and issue its 2002 financial statements, without which the AYE or AE Supply cannot access the public markets, sell certain assets, or obtain approval from the SEC to issue additional secured debts. Secondly, AE Supply is making progress towards monetizing its CDWR Contract with the recent settlement with CDWR. While execution risk exists, the timely monetization of the CDWR Contract at a reasonable price would provide not only the proceeds to meet the 2003 amortization schedule but also free up cash used to post collaterals for hedges. Lastly, external funding by AYE or AE Supply before year end 2003, either in the public or private placement markets, will help to achieve liquidity at AE Supply.
