April 28, 2006

Forward-Looking Statements In addition to historical information, this release contains a number of "forward-looking statements" as defined in the Private Securities Litigation Reform Act of 1995. Words such as anticipate, expect, project, intend, plan, believe, and words and terms of similar substance used in connection with any discussion of future plans, actions, or events identify forward-looking statements. These include statements with respect to: rate regulation and the status of retail generation service supply competition in states served by Allegheny Energy’s distribution business, Allegheny Power; financing plans; demand for energy and the cost and availability of raw materials, including coal; provider-of last-resort and power supply contracts; results of litigation; results of operations; internal controls and procedures; capital expenditures; status and condition of plants and equipment; capacity purchase commitments; regulatory matters; and accounting issues. Forward-looking statements involve estimates, expectations and projections and, as a result, are subject to risks and uncertainties. There can be no assurance that actual results will not materially differ from expectations. Actual results have varied materially and unpredictably from past expectations. Factors that could cause actual results to differ materially include, among others, the following: plant performance and unplanned outages; changes in the price of power and fuel for electric generation; general economic and business conditions; changes in access to capital markets; complications or other factors that render it difficult or impossible to obtain necessary lender consents or regulatory authorizations on a timely basis; environmental regulations; the results of regulatory proceedings, including proceedings related to rates; changes in industry capacity, development and other activities by Allegheny Energy’s competitors; changes in the weather and other natural phenomena; changes in customer switching behavior and their resulting effects on existing and future load requirements; changes in the underlying inputs and assumptions, including market conditions used to estimate the fair values of commodity contracts; changes in laws and regulations applicable to Allegheny Energy, its markets or its activities; the loss of any significant customers or suppliers; dependence on other electric transmission and gas transportation systems and their constraints or availability; changes in PJM, including changes to participant rules and tariffs; the effect of accounting policies issued periodically by accounting standard-setting bodies; and the continuing effects of global instability, terrorism and war. Additional risks and uncertainties are identified and discussed in Allegheny Energy’s reports filed with the Securities and Exchange Commission.

Non-GAAP Financial Measures This presentation includes non-GAAP financial measures as defined in the Securities and Exchange Commission’s Regulation G. Where noted, the presentation shows certain financial information on an “as adjusted” basis, to exclude the effect of certain items as described herein. By presenting “as adjusted” results, management intends to provide investors with a better understanding of the core results and underlying trends from which to consider past performance and prospects for the future. Users of this financial information should consider the types of events and transactions for which adjustments have been made. “As adjusted” information should not be considered in isolation or viewed as a substitute for, or superior to, net income or other data prepared in accordance with GAAP as measures of our operating performance or liquidity. In addition, the “as adjusted” information is not necessarily comparable to similarly titled measures provided by other companies.

Pursuant to the requirements of Regulation G, we have attached a table that reconciles the non-GAAP financial measures in this presentation to the most directly comparable GAAP measures. The table is also available at www.alleghenyenergy.com.
