Item 8.01 Other Material Event.

        On April 13, 2005, Allegheny Energy, Inc. (“AE”) issued a press release announcing a decision by the United States District Court for the Southern District of New York (the “Court”) that granted in part and denied in part cross motions for summary judgment in litigation between (a) AE and its subsidiary, Allegheny Energy Supply Company, LLC (together with AE, “Allegheny”) and (b) Merrill Lynch & Co., Inc., Merrill Lynch Capital Services Inc. and ML IBK Positions, Inc. (collectively, “Merrill”).

        In an Opinion and Order issued on April 12, 2005, the Court addressed cross motions for summary judgment filed by Allegheny and Merrill on February 2, 2005. The motions arose as a result of a dispute between AE and Merrill with regard to Allegheny’s purchase of Merrill’s energy marketing and trading business in 2001. As more fully described in the press release, the Court (a) granted Merrill’s motions for summary judgment on its breach of contract claim and on Allegheny’s counterclaims for breach of fiduciary duty and negligent misrepresentation; (b) denied Merrill’s motion for summary judgment on Allegheny’s counterclaims for fraud and breach of contract and (c) denied Allegheny’s motion for partial summary judgment on Merrill’s breach of contract claim. The press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
