COMBINED NOTES TO FINANCIAL STATEMENTS

(unaudited)



NOTE 1:  BASIS OF PRESENTATION



The
accompanying unaudited interim financial statements of Allegheny Energy, Inc., together with its consolidated subsidiaries, should be read in conjunction with the Annual Report on the combined Form 10-K of Allegheny Energy, Inc.; Allegheny Energy
Supply Company, LLC; Monongahela Power Company; The Potomac Edison Company; West Penn Power Company; and Allegheny Generating Company for the year ended December 31, 2003.



The interim financial statements included herein have been prepared by Allegheny, without audit, pursuant to the rules and
regulations of the SEC. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with Generally Accepted Accounting Principles of the United States of America (GAAP) have been
condensed or omitted, and management believes that the disclosures are adequate to make the information presented not misleading.



In the opinion of management, the unaudited interim financial statements reflect all normal recurring adjustments which are necessary for a fair
presentation of the results of operations for the three months ended March 31, 2004 and 2003; cash flows for the three months ended March 31, 2004 and 2003; and financial position at March 31, 2004 and December 31, 2003. Because of the seasonal
nature of Alleghenys utility operations at Monongahela, Potomac Edison, and West Penn, results for the three months ended March 31, 2004, are not necessarily indicative of results that may be expected for the year ending December 31, 2004. For
more information on the seasonal nature of Alleghenys utility operations, see Part I, Item 1, Risk Factors, Other Risk Factors Associated with Our Business, in Alleghenys 2003 Annual Report on Form 10-K.



Certain amounts in the December 31, 2003 consolidated balance sheets and the
March 31, 2003 statements of operations and cash flows have been reclassified for comparative purposes.



Federal and State Income Taxes.  The provision for income tax expense for earnings from operations and/or the income tax benefit for
losses from operations results in an effective income tax rate, which differs from the federal statutory rate of 35.0 percent, principally due to state income taxes, tax credits, effects of utility rate making and certain non-deductible expenses.



Allegheny allocates income tax expense or benefit to its
subsidiaries pursuant to its consolidated tax sharing agreement. This corporate allocation may cause significant fluctuations in the effective quarterly tax rates from the statutory rates for the subsidiaries depending on the level of pre-tax
profitability.



Stock-Based Employee
Compensation.  Allegheny maintains a stock-based employee compensation plan, which is described in greater detail in Item 8, Note 17, Stock-Based Compensation, to the consolidated financial statements of Alleghenys 2003 Annual
Report on Form 10-K. There were 5.2 million stock options granted in the period from January 1, 2004 through March 31, 2004. There were no stock options granted during the first quarter of 2003.



Allegheny accounts for stock options under the recognition and measurement
principles of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations. No stock-option based compensation expense has been recognized in consolidated net income (loss), as
all options granted under the plan had an exercise price that equaled the market price of the underlying stock on the date of the grant. The following table illustrates the effect on consolidated net income (loss) and income (loss) per share as if
Allegheny had applied the fair value recognition provisions of SFAS No. 123.

NOTE 2:  LONG-TERM DEBT



On March 8, 2004, AE and AE Supply refinanced
approximately $1.6 billion of long-term debt outstanding at December 31, 2003 under the Borrowing Facilities (except for the A-Notes related to AE Supplys St. Joseph, Indiana generating project) with the New Loan Facilities (defined below) in
an aggregate amount of $1.55 billion. As a result of this refinancing, Allegheny and AE Supply wrote off $14.1 million of the 2003 refinancing costs (of which $13.9 million related to AE Supply). These new borrowings are comprised of secured Term B
Loans and secured Term C Loan (collectively, the AE Supply Loans) at AE Supply, in the aggregate amount of $750 million and $500 million, respectively, and unsecured revolving and term loan facilities at AE in the aggregate amount of
$300 million (the New AE Facility, collectively, with the AE Supply Loans, the New Loan Facilities). See Item 8, Note 3, Capitalization, to Alleghenys Annual Report on Form 10-K for the year ended December 31, 2003 for
additional information concerning the refinancing and the debt covenants related to the New Loan Facilities.



Under the New AE Facility, AE has obtained a $300 million credit facility which is comprised of a $100 million term loan and a $200 million revolving
credit facility. The revolving credit facility contains a sub-facility under which a maximum of $100 million of letters of credit may be outstanding at any given time. At March 31, 2004, there was $100 million outstanding under the term loan and
$125 million outstanding under the revolving credit facility, of which $25 million represented outstanding letters of credit. Accordingly, AE had available revolving credit capacity of $75 million, of which the entire amount was available either as
revolving credit or for the issuance of letters of credit.



The
Term B Loans bear interest at AE Supplys option at either LIBOR plus a margin of 3.0 percent per annum or at a base lending rate plus a margin of 2.0 percent per annum, depending on AE Supplys then current credit rating as provided by
Standard and Poors (S&P) and Moodys Investor Services (Moodys).



The Term C Loan bears interest at AE Supplys option of either LIBOR plus a margin of 4.25 percent per annum or at a base lending rate plus a margin of 3.25 percent per annum, depending on AE Supplys then
current credit rating as provided by S&P and Moodys.

Interest on borrowings under the New AE Facility are at AEs option either LIBOR plus a margin of 2.5 to 3.0 percent per annum, or an applicable bank lending base rate plus a margin of 1.5 percent to 2.0 percent per annum, in each case
depending on AEs then current credit rating as provided by S&P and Moodys.



The New AE Facility carries an unused commitment fee of 0.5 percent per annum and letter of credit fees comprised of a fronting fee of 0.35 percent and an additional annual fee of 2.5 to 3.0 percent on the face amount
of outstanding letters of credit, depending on AEs then current credit rating as provided by S&P and Moodys.



At March 31, 2004, no registrant had access to any short-term revolving credit facilities or lines of credit with third party financial institutions
beyond those which have been utilized. As mentioned above, AE had $75 million of revolving credit available under its $200 million revolving credit facility, which is classified as long-term debt in accordance with its terms. See Item 8, Note 3,
Capitalization, in Alleghenys 2003 Annual Report on Form 10-K, for additional information.

NOTE 3:  WHOLESALE ENERGY ACTIVITIES



As of January 1, 2003, EITF Issue No. 02-3, Accounting for Contracts Involved in Energy Trading and Risk Management, resulted in a change in Alleghenys accounting for certain commodity contracts related to AE Supplys
energy trading activities. AE Supply analyzed its commodity contracts to determine which contracts are derivatives as defined by SFAS No. 133. The contracts determined to be derivatives continue to be recorded at their fair values.



In accordance with SFAS No. 133 and EITF 02-3, contracts that have been
determined to be derivatives are recorded as operating revenues at fair value and can result in negative revenue amounts. For the three months ended March 31, 2004 and 2003, AE Supply reported a net realized and unrealized gain of $40.8 million and
a net realized and unrealized loss of $102.2 million from wholesale energy activities, respectively. These amounts are components of operating revenues in AE Supplys consolidated statements of operations. Revenues for the three
months ended March 31, 2004 included the receipt of $70.8 million from escrow upon satisfaction of certain post-closing obligations relating to the sale of the CDWR contract and associated hedge agreements, less a $2.7 million charge representing
the fair value of a related guarantee issued by AE Supply. These revenues were partially offset by realized losses for energy purchases of $43.3 million that were necessary as a result of

outages at Hatfields Ferry Unit No. 2 and Pleasants Unit No. 1. The net realized and unrealized loss for the three months ended March 31, 2003 was primarily due to AE Supplys Western U.S. energy market position. Additionally, AE
Supply made approximately $47.7 million in payments during the three months ended March 31, 2003 to terminate various energy trading contracts.



The net fair value of AE Supplys commodity contracts decreased by $4.5 million for the three months ended March 31, 2004 as a result of $6.1 million
of unrealized losses recorded during the first three months of 2004 which were partially offset by $1.6 million of net options paid and received. There has been, and may continue to be, significant volatility in the market prices for electricity and
natural gas at the wholesale level, which will affect AE Supplys operating results.



NOTE 4:  GOODWILL AND OTHER INTANGIBLE ASSETS



There have been no changes in goodwill for the period December 31, 2003 to March 31, 2004.



The components of other intangible assets, excluding an intangible asset of $40.1 million at March 31, 2004 and $41.7
million at December 31, 2003, related to an additional minimum pension liability (see Item 8, Note 16, Pension Benefits and Postretirement Benefits Other Than Pensions, to AEs 2003 Annual Report on Form 10-K), were as follows:

As described in Note
13 to the consolidated financial statements in the 2003 Annual Report on Form 10-K for AE, the provisions of SFAS No. 71, Accounting for the Effects of Certain Types of Regulation, were reapplied to Monongahelas West Virginia
jurisdictional generating assets in the first quarter of 2003. Upon reapplication of SFAS No. 71, Monongahela and Potomac Edison recorded gains of $61.7 million and $14.1 million, respectively, in other income and expenses, net, in their
consolidated statements of operations. The gains were primarily the result of the elimination of rate stabilization reserves, the reestablishment of regulatory assets related to deferred income taxes and deferred losses on reacquired debt.

NOTE 12:  ASSET RETIREMENT OBLIGATIONS



The effect of adopting SFAS No. 143, Asset Retirement Obligations, on Alleghenys consolidated statements of operations, which was recorded in the period ended March 31, 2003, was a cumulative adjustment to decrease net
income by $8.6 million ($14.0 million, before income taxes). The effect of adopting SFAS No. 143, by registrant, is as follows:

With respect to
property, plant, and equipment at Monongahela for which Asset Retirement Obligations (ARO) were identified and cost of removal currently is being recovered through rates, Allegheny believes it is probable that any difference between expenses under
SFAS No. 143 and expenses recovered currently in rates will be recoverable in future rates and is deferring such expenses as a regulatory asset.



During the three months ended March 31, 2004, Alleghenys ARO balance increased $0.7 million from $22.5 million at December 31, 2003, to $23.2
million at March 31, 2004. This increase, of which $0.6 million related to AE Supply, was due to accretion expense.



Non-legal costs of removal, which are recovered as part of the rate-making process, are recorded by Alleghenys regulated subsidiaries as regulatory
liabilities (assets) as follows:

NOTE 13:  GUARANTEES



At March 31, 2004, Allegheny had provided guarantees,
either directly or indirectly, of $45.6 million for contractual obligations of affiliated companies, as discussed by major category below. This does not include letters of credit. Under the terms of the guarantees, Allegheny would be required to
perform should an affiliate be in default of its obligation, generally for an amount not to exceed the amount disclosed. The term of these guarantees coincides with the term of the underlying agreement.



Of the guarantees provided to third parties, approximately $15.9 million
relates to guarantees associated with the purchase, sale, exchange, or transportation of wholesale natural gas, electric power, and related services. Allegheny provided $15.8 million of these guarantees with the remainder provided by AE Supply.
Allegheny provided loan guarantees of $25.0 million to third parties for loans and other financing related guarantees. Of

these
loan and financing related guarantees, $15.0 million related to AE Supply and $10.0 million related to Allegheny Ventures. Allegheny provided a guarantee of $4.7 million to a third party pursuant to a lease agreement that was signed in 2001. There
are no amounts being carried as liabilities on the consolidated balance sheets for Alleghenys obligations under these guarantees.



As of March 31, 2004, Allegheny recorded as liabilities on its consolidated balance sheet, two guarantees for a total of $9.1 million. These guarantees
were issued by AE Supply in connection with the sale of the CDWR contract and related hedge transactions ($2.7 million) and the performance under a put option issued to a counterparty as part of an asset sale ($6.4 million). The terms of these
guarantees are three and two years, respectively, and the values were determined using a probability weighted cash flow approach.



At March 31, 2004, Potomac Edison had a letter of credit outstanding in the amount of $10.0 million which expires in July 2004 and which was issued in
support of certain energy conservation contracts.



NOTE
14:  VARIABLE INTEREST ENTITIES



Allegheny
adopted FASBs Interpretation No. 46 (Revised December 2003), Consolidation of Variable Interest Entities(FIN 46R), as of March 31, 2004. FIN 46R required Allegheny to consolidate entities or contracts that represent variable interest
in variable interest entities (VIEs) if Allegheny is determined to be the primary beneficiary of the VIE.



Under FIN 46R, Allegheny consolidated Hunlock Creek Energy Ventures, which operates two plants that produce and sell electricity to Allegheny and a third
party, as of March 31, 2004. The consolidation resulted in an increase in total assets of $16.5 million. Beginning April 1, 2004, Allegheny will consolidate the results of operations of this entity; however it will report no incremental net income
as a result, nor will the consolidation of this entity have any impact on Alleghenys consolidated statement of cash flows or consolidated net assets.



After reviewing all other potential impacts under FIN 46R, Allegheny concluded that its two regulated subsidiaries, West Penn and Potomac Edison, each has
a long term electricity purchase contract with an unrelated independent power production company (IPP) that represents a variable interest. Allegheny concluded that these IPPs are VIEs. As a result, the VIEs should be consolidated if either West
Penn or Potomac Edison is determined to be the primary beneficiary of the applicable VIE. Based on a qualitative analysis, Allegheny does not believe that either West Penn or Potomac Edison is the primary beneficiary of either of these VIEs.
However, the information necessary to fully support the position on a quantitative basis is not available from either of the IPPs. Allegheny is attempting to obtain the necessary financial information from each IPP in order to perform a quantitative
analysis. Until Allegheny is able to obtain such information, Allegheny is not required to consolidate these VIEs under FIN 46R.



West Penn and Potomac Edison have annual estimated power purchases from these two IPPs in the amount of $47 million and $95 million, respectively. West
Penn recovers a portion and Potomac Edison recovers the full amount of the cost of the applicable power contract in their rates charged to consumers. Neither West Penn nor Potomac Edison is subject to any risk of loss associated with the applicable
VIE as neither of them has any obligation to the applicable IPP other than purchasing the power that is produced. As of March 31, 2004, the only potential impact of consolidation on West Penns and Potomac Edisons financial statements
would be to their balance sheets. Total assets of West Penn and Potomac Edison would increase $96 million and $432 million, respectively, total liabilities would increase $40 million and $389 million, respectively, and minority interest would
increase $56 million and $43 million, respectively.

NOTE 15:  COMMITMENTS AND CONTINGENCIES



Reference is made to Item 3, Legal Proceedings, and Note 24, Commitments and Contingencies, in the Annual Report on the combined Form 10-K of Allegheny Energy, Inc.; Allegheny Energy Supply Company, LLC; Monongahela Power Company; The
Potomac Edison Company; West Penn Power Company; and Allegheny Generating Company for the year ended December 31, 2003.



Environmental Matters:



Allegheny is subject to various laws, regulations, and uncertainties as to environmental matters. Compliance may require Allegheny to incur substantial
additional costs to modify or replace existing and proposed equipment and facilities and may adversely affect the cost of future operations.



Clean Air Act and CAAA Matters:  In 1998, the EPA finalized its Nitrogen Oxide (NOx) State Implementation Plan (SIP) call rule
(known as the NOx SIP call) to address the regional transport of ground-level ozone that requires the equivalent of a uniform 0.15 lb/mmBtu emission rate throughout a 22-state region, including Maryland, Pennsylvania, and West Virginia, beginning in
May 2003. Alleghenys compliance with such stringent regulations has required and will require the installation of expensive post-combustion control technologies on most of its power stations. During 2000, Pennsylvania and Maryland promulgated
final rules to implement the EPAs NOx SIP call requirements, beginning in May 2003. During 2001, the West Virginia Department of Environmental Protection issued a final rule to implement the EPAs NOx SIP call requirements, beginning in
May 2004. The EPA approved the West Virginia SIP in July 2002. The District of Columbia Circuit Court of Appeals issued a subsequent order that postponed the initial compliance date of the NOx SIP call from May 2003 to May 2004. Maryland and
Pennsylvania did not delay the May 2003 implementation dates of their respective SIP, nor are they legally required to do so. AE Supply and Monongahela are in the process of installing NOx controls to meet the Pennsylvania, Maryland, and West
Virginia SIP. These NOx controls include the installation of Selective Catalytic Reduction at the Harrison Power Station and Pleasants Power Station that comply with the NOx emission limits when in operation. Boiler modifications and Selective
Noncatalytic Reduction at Hatfields Ferry Power Station and Fort Martin Power Station, as well as burner modifications at Mitchell Power Station are being staged into service to further control emissions at those sources. The NOx Compliance
Plan was established on a system-wide basis much the same as was the SO2Compliance Plan. AE Supply and Monongahela
also have the option to purchase, in some cases, alternate fuels, NOx allowances, or power on the market, if needed, to supplement their compliance strategy. AE Supply and Monongahela estimate their emission control activities in concert with their
inventory of banked allowances will facilitate their compliance with NOx limits established by the SIP through 2005 and possibly beyond. Alleghenys construction forecast includes the expenditure of $10.2 million of capital costs during the
2004 through 2005 period for NOx emission controls.



In August
2000, AE received a letter from the EPA requesting that it provide information and documentation relevant to the operation and maintenance of the following ten electric generating stations, collectively including 22 generating units: Albright,
Armstrong, Fort Martin, Harrison, Hatfields Ferry, Mitchell, Pleasants, Rivesville, R. Paul Smith, and Willow Island. AE Supply and Monongahela own these electric generating stations. The letter requested information under Section 114 of the
Clean Air Act to determine compliance with the Clean Air Act and related requirements, including potential application of the New Source Review (NSR) standards of the Clean Air Act, which can require the installation of additional air pollution
control equipment upon the major modification of an existing facility. Responsive submissions were made during 2000 and 2001. In July 2002, AE received a follow-up letter from the EPA requesting clarifying information. AE has provided responsive
information.

Similar inquiries have been made of other electric utilities and have resulted in enforcement proceedings being brought in most cases. AE believes that its subsidiaries generating facilities have been operated in accordance with the
Clean Air Act and the rules implementing it. The experience of other energy companies, however, suggests that, in recent years, the EPA has narrowed its view regarding the scope of the definition of routine maintenance under its rules,
thereby broadening the range of actions subject to compliance with NSR standards. Under previous EPA interpretations, these same actions did not trigger application of those standards. Section 114 information requests concerning facility
modifications are often followed by enforcement actions. The EPA contacted AE and requested a meeting, which was held on July 16, 2003.



At this time, AE is not able to determine what effect the EPAs inquiry may have on its operations. If NSR standards are applied to Alleghenys
generating stations, in addition to the possible imposition of fines, compliance would entail significant expenditures. However, on April 13, 2004, Duke Energy (Duke) reported that the EPA and three intervening environmental groups have
agreed to drop their lawsuit against Duke, which alleged that Duke violated the NSR standards. In addition, the final Routine Maintenance, Repair, and Replacement Rule (RMRR) recently released by the EPA, are more consistent with the energy
industrys historical compliance approach. On December 24, 2003, the U.S. Court of Appeals for the District of Columbia Circuit issued an order to stay the RMRR. The RMRR was scheduled to go into effect on December 26, 2003. The stay delays
implementation of the RMRR. At this time, AE and its subsidiaries are not able to determine the effect that these actions may have on them with regard to compliance costs.



The Attorneys General of New York and Connecticut, in letters dated September 15, 1999 and November 3, 1999, respectively,
notified AE of their intent to commence civil actions against AE and/or its subsidiaries alleging violations at the Fort Martin Power Station under the Clean Air Act, which requires power plants that make major modifications to comply with the same
NSR standards applicable to new power plants. Other governmental agencies may commence similar actions in the future. The Fort Martin Power Station is located in West Virginia and is now jointly owned by AE Supply and Monongahela. Both Attorneys
General stated their intent to seek injunctive relief and penalties. In addition, the Attorney General of the State of New York indicated that he may assert claims under New Yorks common law of public nuisance seeking to recover, among other
things, compensation for alleged environmental damage caused in New York by the operation of the Fort Martin Power Station. On February 2, 2004, AE was informed by the EPA that the EPA intends to provide the New York Attorney General, pursuant to
his request, certain records which AE provided to the EPA pursuant to its request under Section 114 of the Clean Air Act. On April 23, 2004, AE Supply was notified by the Pennsylvania Department of Environmental Protection (PADEP) that PADEP has
requested that the EPA provide it with records provided by AE to the EPA pursuant to the EPAs request under Section 114 of the Clean Air Act. At this time, AE and its subsidiaries are not able to determine the effect these actions may have on
them.



Comprehensive Environmental Response,
Compensation, and Liability Act of 1980 (CERCLA) Claim:  On March 4, 1994, the Distribution Companies received notice that the EPA had identified them as potentially responsible parties (PRPs) with respect to the Jacks
Creek/Sitkin Smelting Superfund Site. Initially, approximately 175 PRPs were involved, however, the current number of active PRPs has been reduced as a result of settlements with de minimis contributors and other contributors to the site. The costs
of remediation will be shared by all past and active responsible parties. In 1999, a PRP group that included the Distribution Companies entered into a consent order with the EPA to remediate the site. It is currently estimated that the total
remediation costs to be borne by all of the responsible parties will not exceed $30.0 million. Allegheny estimates that its share of the remediation liability will not exceed $1.0 million, which has been accrued as a liability.



Other:  As part of the National Pollutant Discharge
Elimination System permit review process at the Connellsville West Side facility, oil and PCB contamination has been noted at the facility. Steps have been taken

to
control the contamination and monitoring is continuing at the site. The internal investigation into the source of the oil is ongoing in accordance with several Pennsylvania Department of Environmental Protection programs. West Penn has accrued a
liability in December 2002 and December 2003 as an estimate of the total remediation cost at the facility.



Other Litigation:



Putative Class Actions Under California Statutes:  Nine related putative class action lawsuits against AE Supply and more than two
dozen other named defendant power suppliers were filed in various California superior courts during 2002. These class action suits were removed from federal court and transferred to the U.S. District Court for the Southern District of California.
Eight of the suits were commenced by consumers of wholesale electricity in California. The ninth, Millar v. Allegheny Energy Supply Co., et al., was filed on behalf of California consumers and taxpayers. The complaints allege, among
other things, that AE Supply and the other defendant power suppliers violated Californias antitrust statute and the California unfair business practices statute by allegedly manipulating the California electricity market. The suits also
challenge the validity of various long-term power contracts with the State of California, including AE Supplys contract with the CDWR (CDWR contract).



On August 25, 2003, AE Supplys motion to dismiss seven of the eight consumer class actions with prejudice was granted by the U.S. District Court.
Plaintiffs counsel in these seven actions filed a notice of appeal to the United States Court of Appeals for the Ninth Circuit on September 29, 2003. AE Supply was not served in the eighth consumer class action, Kurtz v. Duke Energy
Trading and Marketing, LLC. The allegations in this complaint were substantively identical to those in the dismissed actions. On February 18, 2004, plaintiffs in Kurtz v. Duke Energy Trading and Marketing, LLC voluntarily dismissed
the action without prejudice.



AE Supply cannot predict the
outcome of these matters.



Nevada Power
Contracts:  On December 7, 2001, Nevada Power Company (NPC) filed a complaint with the FERC against AE Supply, which sought FERC action to modify prices payable to AE Supply under three trade confirmations dated December 4, 2000,
January 16, 2001, and February 7, 2001, between Merrill Lynch and NPC, and entered into under the Western Systems Power Pool Master Agreement. The transactions related to power sales during 2002. NPCs claim was based, in part, on the assertion
that dysfunctional California spot markets had an adverse effect on the prices NPC was able to negotiate with Merrill Lynch under the contracts. NPC filed substantially identical complaints against a number of other energy suppliers. On December 19,
2002, the Administrative Law Judge (ALJ) issued findings that no contract modification was warranted. The ALJ determined in favor of NPC that AE Supply, rather than Merrill Lynch, was a proper subject of NPCs complaint.



On June 26, 2003, the FERC affirmed the ALJs decision upholding the
long-term contracts negotiated between NPC and Merrill Lynch, among others. The FERC did not render a decision on whether AE Supply, rather than Merrill Lynch, was the real party in interest to the three trade confirmations at issue. On November 10,
2003, the FERC issued an order, on rehearing, affirming its conclusion that the long-term contracts should not be modified. On July 3, 2003, Snohomish County filed a petition for review of the FERCs June 26 order with the U.S. Court of Appeals
for the Ninth Circuit. Additional appeals have been filed. On December 10, 2003, the NPC petitions were consolidated in the Ninth Circuit. AE Supply cannot predict the outcome of this matter.



Sierra/Nevada:  On April 2, 2003, NPC and Sierra
Pacific Resources, Inc. (together Sierra/Nevada) initiated a lawsuit in U.S. District Court in Nevada against AE and AE Supply, together with Merrill Lynch & Co. and Merrill Lynch Capital Services, Inc. (together, Merrill). The complaint alleged
that AE, AE Supply and Merrill engaged in fraudulent conduct in connection with NPCs application to the Public Utilities Commission of

Nevada
(Nevada PUC) for a deferred energy accounting adjustment, which allegedly caused the Nevada PUC to disallow $180.0 million of NPCs deferred energy expenses. Sierra/Nevada asserted three causes of action against AE and AE Supply arising from
the alleged fraudulent conduct. These include: (1) tortious interference with Sierra/Nevadas contractual and prospective economic advantages, (2) conspiracy, and (3) violations of the Nevada state Racketeer Influenced and Corrupt Organization
(RICO) Act. Sierra/Nevada filed an amended complaint on May 30, 2003 in which it asserted a fourth cause of action against AE and AE Supply for wrongful hiring and supervision. Sierra/Nevada seeks $180.0 million in compensatory damages plus
attorneys fees. Under the RICO count, Sierra/Nevada seeks in excess of $850.0 million. AE and AE Supply filed motions to dismiss the complaints on May 6, 2003 and June 23, 2003. Sierra/Nevada filed an opposition on July 21, 2003. On March 17, 2004,
Sierra/Nevada filed a motion to stay this matter pending final judgment after remand in a related matter pending before the Supreme Court of the State of Nevada (Nevada Power Company v. Public Utilities Commission of Nevada, et al., Case No.
41492). The District Court, in connection with its consideration of Sierra/Nevadas motion to stay, issued an order on March 30, 2004, denying defendants pending motions to dismiss without prejudice to their subsequent right to re-file
them. AE and AE Supply cannot predict the outcome of this matter.



Litigation Involving Merrill Lynch:  AE and AE Supply entered into an asset purchase agreement with Merrill Lynch and affiliated parties in 2001, under which AE and AE Supply purchased Merrill Lynchs energy
marketing and trading business for approximately $489 million and an equity interest in AE Supply of nearly two percent. The asset purchase agreement provided that Merrill Lynch would have the right to require AE to purchase Merrill Lynchs
equity interest in AE Supply for $115 million plus interest calculated from March 16, 2001 in the event that certain conditions were not met.



On September 24, 2002, certain Merrill Lynch entities filed a complaint against AE in the U.S. District Court for the Southern District of New York,
alleging that AE breached the asset purchase agreement by failing to repurchase the equity interest in AE Supply from Merrill Lynch and seeking damages in excess of $125 million.



On September 25, 2002, AE and AE Supply commenced an action against Merrill Lynch in the Supreme Court of the State of New
York for the County of New York. The complaint in that lawsuit alleges that Merrill Lynch fraudulently induced AE to enter into the purchase agreement and that Merrill Lynch breached certain representations and warranties contained in the purchase
agreement. The lawsuit sought damages in excess of $605 million, among other relief.



On October 23, 2002, AE filed a motion to stay Merrill Lynchs federal court action in favor of AE and AE Supplys action in New York state court. On May 29, 2003, the U.S. District Court for the Southern
District of New York denied AEs motion to stay Merrill Lynchs action and ordered that AE and AE Supply assert its claims against Merrill Lynch, which were initially brought in New York state court, as counterclaims in Merrill
Lynchs federal court action. As a result, AE and AE Supply dismissed its New York state action and, on June 13, 2003, AE and AE Supply filed an answer, affirmative defense and counterclaims against Merrill Lynch in the U.S. District Court for
the Southern District of New York. The counterclaims allege that Merrill Lynch fraudulently induced AE and AE Supply to enter into the purchase agreement, that Merrill Lynch breached certain representations and warranties contained in the purchase
agreement, and that Merrill Lynch breached fiduciary duties owed to AE and AE Supply. The counterclaims seek damages in excess of $605 million, among other relief.



On August 29, 2003, AE and AE Supply filed amended counterclaims that, among other things, added a claim against Merrill
Lynch for negligent misrepresentation. On November 24, 2003, the Court dismissed AE and AE Supplys counterclaim for rescission and struck their demand for a jury trial with respect to certain

counterclaims. AE and AE Supplys counterclaims for negligent misrepresentation, fraudulent inducement, breach of contract, breach of fiduciary duty and punitive damages remain in place. On January 23, 2004, the Court granted a motion
filed under seal by the U.S. Attorney for the Southern District of New York to intervene and stay deposition discovery for approximately six months. Document discovery is continuing, and deposition discovery may proceed to the extent agreed by the
U.S. Attorney. The case has been set for trial on October 4, 2004.



The federal government is holding approximately $43.0 million and other assets of Daniel L. Gordon, the former head of energy trading for AE Supply. Both AE and Merrill Lynch have filed petitions with the U. S. District Court for the
Southern District of New York claiming rights to the funds.



AE
and AE Supply cannot predict the outcome of these matters.



Putative Shareholder, Derivative, and Benefit Plan Class Actions:  From October 2002 through December 2002, plaintiffs claiming to represent purchasers of AEs securities filed 14 putative class action lawsuits
against AE and several of its former senior managers in U.S. District Courts for the Southern District of New York and the District of Maryland. The complaints allege that AE and senior management violated federal securities laws when AE purchased
Merrill Lynchs energy marketing and trading business with the knowledge that the business was built on illegal wash or round-trip trades with Enron, which the complaints allege artificially inflated trading revenue, volume and growth. The
complaints assert that AEs fortunes fell when Enrons collapse exposed what plaintiffs claim were illegal trades in the energy markets. On May 3, 2004, the plaintiffs filed an amended complaint to consolidate the foregoing actions. The
complaints do not specify requested relief.



In February and
March 2003, two putative class action lawsuits were filed against AE in U.S. District Courts for the Southern District of New York and the District of Maryland. The suits allege that AE and a senior manager violated the Employee Retirement Income
Security Act of 1974 (ERISA) by: (1) failing to provide complete and accurate information to plan beneficiaries regarding the energy trading business, among other things; (2) failing to diversify plan assets; (3) failing to monitor investment
alternatives; (4) failing to avoid conflicts of interest; and (5) violating fiduciary duties. On April 26, 2004, plaintiffs in the ERISA cases filed an amended complaint, adding a number of individuals as defendants and clarifying the nature of
their claims.



In June 2003, a shareholder derivative action
was filed against AEs Board of Directors and several former senior managers in the Supreme Court of the State of New York for the County of New York. The suit alleges that the Board and senior management breached fiduciary duties to AE that
have exposed AE to the securities class action lawsuits. The derivative action has been stayed pending the commencement of discovery in the securities cases.



Both the securities cases and the ERISA cases have been transferred to the District of Maryland for coordinated or consolidated pretrial proceedings. AE
cannot predict the outcome of these matters.



Claims
Related to Alleged Asbestos Exposure:  Monongahela, Potomac Edison, and West Penn have also been named as defendants along with multiple other defendants in pending asbestos cases alleging bodily injury involving multiple
plaintiffs and multiple sites. These suits have been brought mostly by seasonal contractor employees and do not involve allegations of either the manufacture, sale or distribution of asbestos-containing products by Allegheny (the asbestos
suits). The asbestos suits arise out of historical operations and are related to the removal of asbestos-containing materials from Alleghenys premises. Alleghenys historical operations were insured by various foreign and domestic
insurers, including Lloyds of London. Alleghenys asbestos-related litigation expenses have to date been reimbursed in full by recoveries from its historical insurers and Allegheny believes that it has sufficient insurance to respond
fully to the asbestos suits. Certain of Alleghenys

insurers, however, have contested their obligations to pay for the future defense and settlement costs relating to the asbestos suits. Allegheny is currently involved in two asbestos insurance-related actions that were commenced in 2003,
Certain Underwriters at Lloyds, London et al. v. Allegheny Energy, Inc. et al., Case No. 21-C-03-16733 (Washington County, Md.), and Monongahela Power Company et al. v. Certain Underwriters at Lloyds London and London Market
Companies, et al., Civil Action No. 03-C-281 (Monongalia County, W.Va.), (collectively, the actions). The parties in the actions are seeking an allocation of responsibility for Alleghenys historic asbestos liability. Allegheny
is continuing to receive payments from its insurance during the pendency of these actions, specifically the sum of $1.875 million, payable in equal parts on each of July 1, 2004, 2005 and 2006. During the three months ended March 31, 2004, Allegheny
received insurance recoveries of $0.3 million, net of $0.1 million of legal fees, related to the asbestos cases. There were no such insurance recoveries received during the three months ended March 31, 2003. Allegheny does not believe that the
existence or pendency of either the asbestos suits or the actions involving its insurance will have a material impact on Alleghenys consolidated financial position, results of operations or cash flows. Allegheny believes that it has
established adequate reserves, net of insurance receivables and recoveries, to cover existing and future asbestos claims. As of March 31, 2004, the Company had 1,409 open cases remaining. While Allegheny believes that all of the cases are without
merit, Allegheny cannot predict the outcome of the litigation.



Suits Related to the Gleason Generating Facility:  Allegheny Energy Supply Gleason Generating Facility, LLC, a subsidiary of AE Supply, is the defendant in a suit brought in the Circuit Court for Weakley County,
Tennessee, by residents living in the vicinity of the generating facility in Gleason, Tennessee. The original suit was filed on September 16, 2002. AE Supply purchased the peaking facility in 2001. The plaintiffs are asserting claims based on
trespass and/or nuisance, claiming personal injury and property damage as a result of noise from the generating facility during operation. They seek a restraining order with respect to the operation of the plant and damages of $200 million. The case
was assigned to mediation on October 14, 2003 and the judge has ordered the mediation to conclude by July 1, 2004. AE has undertaken property purchases and other mitigation measures. AE cannot predict the outcome of this suit.



AE Supply has demanded indemnification from Siemens Westinghouse, the
manufacturer of the turbines used in the Gleason Generating Facility, pursuant to the terms of the equipment purchase agreement. On October 17, 2002, Siemens Westinghouse filed a request for a declaratory judgment in the Court of Common Pleas of
Allegheny County, Pennsylvania seeking a declaration that the prior owner released Siemens Westinghouse from this liability through a release executed after Allegheny purchased the Gleason facility. This case is currently in the discovery process.
AE cannot predict the outcome of this suit or whether it will be able to recover amounts from Siemens Westinghouse.



SEC Matters:  On October 9, October 25, and November 5, 2002, AE received subpoenas from the SEC. The subpoenas principally
concerned: (1) the departure of Daniel L. Gordon, the former head of energy trading for AE Supply; (2) AEs litigation with Merrill Lynch; (3) AE Supplys valuation and management of its trading business; (4) AEs November 4, 2002,
press release concerning its financial statements; (5) the departure of AEs and its subsidiaries Controller, Thomas Kloc, in June 2002; and (6) AEs acquisition of power plants from Enron. AE and AE Supply responded to the
subpoenas.



On January 16, 2004, the SEC requested that AE
voluntarily produce certain documents in connection with an informal investigation of AE. Many of these documents were previously provided in response to subpoenas that AE received in 2002 and most of the documents requested by the SEC have been
produced. Several former employees of AE have been deposed by the SEC. AE is cooperating fully with the SEC.

Commodities Futures Trading Commission (CFTC) Subpoenas:  On October 2, 2002 and January 15, 2003, AE and AE Supply received subpoenas from the CFTC for documents relating to natural gas and electricity trading. AE
and AE Supply responded to the subpoenas. Two current and two former employees have been deposed by the CFTC, and several additional interviews of former employees are scheduled. AE and AE Supply are cooperating fully with the CFTC.



EPMI Adversary Proceeding:  On May 9, 2003, Enron
Power Marketing, Inc. (EPMI), a Chapter 11 debtor, commenced an adversary proceeding against AE Supply in its bankruptcy case that is pending in the U.S. Bankruptcy Court for the Southern District of New York. The complaint alleges that AE Supply
owes EPMI (1) $27,646,725 for accounts receivable due and owing for energy delivered prior to the commencement of EPMIs bankruptcy case, and (2) $8,250,000 in cash collateral previously posted to AE Supply, less any amounts owed to AE Supply
as a result of EPMIs default under a master trading agreement entered into between the parties and certain transactions arising thereunder. By the complaint, EPMI also seeks certain declaratory relief, including a declaration that the
arbitration provision found in the master trading agreement is unenforceable. On August 1, 2003, AE Supply filed an answer asserting affirmative defenses. Many similar cases have been filed by, or against, EPMI in its bankruptcy case. The bankruptcy
court has determined that such cases should be resolved through mediation, if possible. Mediation of the subject complaint began on October 28, 2003, and the parties will continue the mediation process. AE Supply is unable to predict the outcome of
this matter.



LTI Arbitration.  On
April 22, 2004, Leasing Technologies International, Inc. and its shareholders (collectively, LTI) filed a demand for arbitration against Allegheny Ventures, Inc. and AE before the American Arbitration Association. In December 2000,
Allegheny Ventures entered into an agreement to acquire LTI, an equipment leasing company. Allegheny Ventures terminated the agreement on May 4, 2003. LTI alleges that the termination of the agreement was unjustified and seeks damages in an
unspecified amount for breach of the agreement as well as other consequential damages. AE has not yet responded and cannot predict the outcome of this matter.



Ordinary Course of Business:  The registrants are from time to time involved in litigation and other legal disputes in the
ordinary course of business. Each registrant is of the belief that there are no other legal proceedings, which could materially impair its operations or materially or adversely affect its financial condition or liquidity.



NOTE 16:  GENERATING UNIT OUTAGES



On November 3, 2003, there was a fire in Unit No. 2 at the Hatfields
Ferry Power Station located near Masontown, Pennsylvania. Unit No. 2 is a 570 MW coal-fired generating unit owned by AE Supply and Monongahela. As a result of the fire, significant damage was sustained to the generator and turbine and certain
associated equipment. The unit is currently off-line and is expected to return to service late in the second quarter of 2004.



On February 9, 2004, a generator failure occurred in Unit No. 1 at the Pleasants Power Station located in Willow Island, West Virginia. Unit No. 1 is a
650 MW coal-fired generating unit owned by AE Supply and Monongahela. As a result of the generator failure, damage was sustained to the generator and associated equipment. The unit is currently off-line and is expected to return to service late in
the second quarter of 2004.

|- |  | -----------------------------------------------------



Alleghenys consolidated net income before cumulative effect of accounting change increased $71.3 million for the three months ended March 31, 2004
as compared to the same period in 2003, primarily due to reduced losses in the Generation and Marketing segment. These were a result of reduced realized and unrealized losses on commodity contracts in 2004 compared to the same period in 2003. Both
the Delivery and Services and the Generating and Marketing segments experienced lower operating costs partially offset by higher interest expense and depreciation expense.

##### Table of Contents

For the three months ended March 31, 2003, consolidated net loss included $12.1 million, net of income
taxes, reflecting the cumulative effect of the accounting change associated with the adoption of EITF Issue No. 02-3, Accounting for Contracts Involved in Energy Trading and Risk Management.



Also for the three months ended March 31, 2003, consolidated net loss
included $8.6 million, net of income taxes, reflecting the cumulative effect of the accounting change associated with the adoption of SFAS No. 143, Accounting for Asset Retirement Obligations. See Note 12, Asset Retirement Obligations,
above, for additional information.



In addition,
Alleghenys operating results were negatively impacted in the first quarter of 2004 by unplanned outages at Hatfields Ferry Unit No. 2 and Pleasants Unit No. 1. Allegheny estimates that the total impact of these outages on its pre-tax
income for the first quarter of 2004 was approximately $34 million, consisting primarily of lost revenues (less savings on fuel costs) and repair and replacement costs (net of anticipated insurance proceeds). Allegheny expects both units to return
to service late in the second quarter of 2004. This information is based on current assumptions and estimates. Accordingly, actual results may vary and these variations may be material.

|* |  | In accordance with EITF 02-3, energy trading revenues are reported net of purchased energy, which resulted in negative revenue amounts for the three months ended March 31, 2003.
|- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Delivery and
Services:  The Delivery and Services segments retail electric revenues for the three months ended March 31, 2004 increased $11.2 million as compared to the three months ended March 31, 2003. This was primarily due to an
increase in industrial, residential, and commercial sales driven by increased usage, largely offset by a decrease in wholesale sales.



The Delivery and Services segments retail natural gas revenues increased $29.0 million for the three months ended March 31, 2004 as compared to the
same period in 2003, primarily due to an increase in a retail tariff effective October 2, 2003 to cover the increase in purchased gas costs. This increase was partially offset by a combined 10.0 percent decrease in residential, commercial,
industrial, and wholesale gas sales.

##### Table of Contents

The Delivery and Services segments bulk power revenues decreased $10.0 million for the three months
ended March 31, 2004 as compared to the same period in 2003, primarily due to the loss of four wholesale customers as a result of contract expirations and lower PJM transmission service revenue.



The Delivery and Services segments unregulated services revenues
decreased $10.7 million for the three months ended March 31, 2004 as compared to the same period in 2003. This decrease was primarily the result of lower revenue recognition on the South Mississippi Electric Power Association percentage of
completion construction contract in the first quarter of 2004 as compared to the same period in 2003.



Generation and Marketing:  The operating revenues of $432.8 million for the Generation and Marketing segment for the three months
ended March 31, 2004 include PLR revenues of $405.6 million. Operating revenues have been reduced by $(49.0) million which principally represents increased costs of purchased power necessitated by the outages at Hatfields Ferry Unit No. 2 and
Pleasants Unit No. 1. These revenues also include the release of escrow proceeds of $70.8 million, less a $2.7 million provision for indemnification associated with the sale of the CDWR contract and related hedge transactions, other revenues of $7.6
million, and other trading activities of $0.5 million.



The
Generation and Marketing segments bulk power revenues for the three months ended March 31, 2004 increased $142.4 million as compared to the same period in 2003, primarily due to reduced realized and unrealized losses on commodity contracts in
2004 compared to the same period in 2003. This reduction reflects AE Supplys exit from the Western U.S. energy markets in 2003 and the release of escrow proceeds related to the sale of the CDWR contract.



The Generation and Marketing segments affiliated and other revenues for
the three months ended March 31, 2004 increased $9.6 million as compared to the same period in 2003. This was primarily due to increased sales volumes at higher prices in accordance with the long-term power sales agreements between AE Supply and the
Distribution Companies.



The elimination between Delivery and
Services and Generation and Marketing revenues is necessary to remove the effect of affiliated revenues.



Operating Expenses



Fuel consumed in electric generation:  Fuel consumed in electric generation, which relates entirely to the Generation and Marketing segment, represents the cost of coal, natural gas, and oil burned at
Alleghenys generating stations to produce electricity. Fuel consumed in electric generation increased $3.2 million due primarily to the increased cost of fuel consumed at the gas-fired generating stations, including the amount attributable to
increased energy production from AE Supplys generating facility in Springdale, Pennsylvania, which became operational in July 2003. Additionally, coal expenses decreased in the first quarter of 2004, primarily due to a decrease in coal
consumed as a result of the outages at Hatfields Ferry Unit No. 2 and Pleasants Unit No. 1.

The Delivery and
Services segments purchased energy from PURPA generation decreased $4.7 million for the three months ended March 31, 2004 as compared to the same period in 2003. The decrease in PURPA generation expense was primarily due to a 0.9 percent
decrease in MWhs generated resulting from PURPA plant outages.



The Delivery and Services segments other purchased energy expense, which consists primarily of the Distribution Companies purchases of energy from AE Supply, increased $10.4 million for the three months ended March 31, 2004 as
compared to the same period in 2003. The increase in other purchased energy expense was primarily due to increased sales volumes at higher prices in accordance with the long-term power sales agreements between AE Supply and the Distribution
Companies.



The eliminations are necessary to remove the effect
of affiliated purchased energy and transmission expenses.



Cost of utility gas sold:  Cost of utility gas sold for the three months ended March 31, 2004 and 2003 was as follows:

The Delivery and
Services segments cost of utility gas sold decreased $5.5 million for the three months ended March 31, 2004, as compared to the same period in 2003, primarily due to a 12.5 percent decrease in gas purchases which were partially offset by a 7.8
percent increase in gas prices.



Deferred energy costs,
net:  The difference between energy costs and revenues collected from customers is deferred until recovered from or credited to customers under a purchased energy adjustment and has no impact on operating income. Deferred energy
costs, net, increased $30.4 million for the three months ended March 31, 2004 as compared to the same period in 2003, resulting from higher natural gas prices incurred primarily by Monongahela for its West Virginia natural gas operations, which are
expected to be recovered through customer rates.

Total operations and
maintenance expense decreased $100.7 million for the three months ended March 31, 2004 as compared to the same period in 2003, primarily as a result of 2003 costs that did not recur in 2004. For the Generation and Marketing segment, these costs
included asset retirement losses of $33.5 million, expenses for professional services, primarily accounting, legal and financial, of $22.2 million, litigation reserves of $7.0 million, employee benefit costs of $5.6 million, and lease termination
costs of $2.5 million. For the Delivery and Services segment, the 2003 costs that did not recur in 2004, or were incurred at lower amounts, included employee benefit costs of $6.6 million, decreased expenses for professional services, primarily
accounting, legal and financial, of $4.9 million, and unrecoverable damages for an ice storm in the three months ended March 31, 2003 of $2.5 million. The decrease in 2004 operations and maintenance costs was partially offset by charges recorded in
the first quarter of 2004 associated primarily with a write-down of certain inventory to its estimated market value of $3.5 million.



Depreciation and amortization:  Depreciation and amortization expense increased $5.7 million primarily related to the AE Supply
generating facility in Springdale, Pennsylvania, which became operational in July 2003, and the installation of environmental control equipment at Pleasants Units No. 1 and No. 2.



Taxes other than income taxes:  Taxes other than income taxes decreased $1.1 million for the
three months ended March 31, 2004. This decrease was primarily the result of a settlement of certain prior years property tax assessments.



Other Income, Net



Other income, net, decreased $72.2 million and represents non-operating income and expenses before income taxes. Other income, net, decreased primarily as
a result of a $75.8 million gain recognized in the first quarter of 2003, related to the reapplication of the provisions of SFAS No. 71 to generation assets in West Virginia, which did not recur in 2004. The decrease in other income, net, was
partially offset by the recognition of the $6.6 million gain in the first quarter of 2004 related to the sale of land in West Virginia.

##### Table of Contents

Interest expense and preferred dividends increased $35.4 million for the three months ended March 31,
2004 as compared to same period in 2003, primarily due to an increase in average debt outstanding as a result of the July 2003 issuance of mandatory-convertible preferred securities which were not outstanding during the first quarter of 2003 and the
write-off of $14.1 million of the 2003 refinancing issuance costs as a result of the March 2004 refinancing. The first quarter 2004 results do not reflect a full quarter of lower interest expense because the March 2004 refinancing closed on March 8,
2004.



Income Tax Expense (Benefit)



The provision for income tax expense for earnings from operations and/or the
income tax benefit for losses from operations results in an effective income tax rate, which differs from the federal statutory rate of 35.0 percent principally due to state income taxes, tax credits, effects of utility rate-making, and certain
non-deductible expenses.



The effective income tax rates for
the three months ended March 31, 2004 and 2003 were 42.1 percent and 48.2 percent, respectively. The change in the effective income tax rate for the three months ended March 31, 2004 is primarily a result of the tax benefit of the reapplication of
SFAS No. 71 recognized in the first quarter of 2003 which did not recur in 2004 and the impact of rate regulation and depreciation, which were partially offset by the impact of certain employee benefits.



Cumulative Effect of Accounting Changes, Net



The following items were recorded in the first quarter of 2003:



Effective January 1, 2003, Allegheny adopted EITF Issue No. 02-3. As a
result, Allegheny recorded a charge against earnings, related entirely to the operations at AE Supply, as the cumulative effect of a change in accounting principle of $12.2 million, net of income taxes ($19.7 million, before income taxes),
representing the fair value of those contracts previously accounted for under EITF Issue No. 98-10, Accounting for Contracts Involved in Energy Trading and Risk Management Activities, that no longer qualify for mark-to-market accounting.



Effective January 1, 2003, Allegheny adopted SFAS No. 143. As
a result, Allegheny recorded a charge against earnings as the cumulative effect of a change in accounting principle of $8.6 million, net of income taxes ($14.0 million, before income taxes). See Note 12, Asset Retirement Obligations, above for
additional information.

AE SUPPLYS RESULTS OF OPERATIONS



Income (Loss) Summary



Net income increased by $155.1 million primarily due to increased operating revenues as a result of lower realized and
unrealized losses on commodity contracts in 2004, and lower operating costs partially offset by higher interest expense and depreciation expense. During the first quarter of 2004, AE Supply recorded a gain of $68.1 million representing the receipt
of $70.8 million from escrow upon satisfaction of certain post-closing obligations relating to the sale of the CDWR contract and associated hedge agreements, less a $2.7 million charge representing the fair value of a related guarantee issued by AE
Supply. The realized and unrealized losses during the first quarter of 2003 were due primarily to trading activities in the Western U.S. energy markets, which AE Supply exited in 2003.



The first quarter of 2004 results were significantly impacted by two low-cost generating facilities being off-line during
all or part of the quarter. On February 9, 2004, a generator failure occurred on the 650 MW Unit No. 1 at Pleasants Power Station located in Willow Island, West Virginia. In addition, the 570 MW Unit No. 2 at Hatfields Ferry has been off-line
since a November 3, 2003 fire at the facility. During the first quarter of 2004, AE Supply incurred a loss of revenues or had to purchase power in the market at costs that were higher than the internal cost of production, each of which resulted in
reduced operating income. Both units are expected to return to service late in the second quarter of 2004.



In the first quarter of 2003, earnings were reduced by $12.2 million and $7.4 million, net of income taxes, reflecting the cumulative effect of the
accounting changes associated with the adoptions of EITF Issue No. 02-3 and SFAS No. 143, respectively.



Operating Revenues



Total operating revenues for the three months ended March 31, 2004 and 2003 were as follows:

The operating revenues
of $362.6 million for the three months ended March 31, 2004 include PLR revenues of $325.8 million. Operating revenues have been reduced by $(43.3) million which principally represents increased costs from purchased power due to the outages at
Hatfields Ferry Unit No. 2 and Pleasants Unit No. 1. These revenues also include the release of escrow proceeds of $70.8 million, less a $2.7 million provision for indemnification, associated with the sale of the CDWR contract and related
hedge transactions, other revenues of $11.5 million, and other trading activities of $0.5 million.

##### Table of Contents

Wholesale revenue increased by $143.0 million primarily due to the significant reduction, in the first
quarter of 2004, of realized and unrealized losses. Approximately $103.2 million of the increase results from AE Supplys exit from the Western U.S. energy markets in 2003. Also contributing to this increase was the release from escrow of $70.8
million related to the sale of the CDWR contract and associated hedge transactions. These increases were partially offset by reduced generation revenue as a result of Hatfields Ferry Unit No. 2 and Pleasants Unit No. 1 being off-line during
all or part of the first quarter of 2004.



See Item 7,
Managements Discussion and Analysis, for AE Supply in the 2003 Annual Report on Form 10-K for discussions surrounding the methodology, tenor, and description of AE Supplys trading portfolio, as well as a description with respect to
the range of observable market prices and overall market liquidity. There has been no significant change in the methodology for valuing the portfolio during the three months ended March 31, 2004. All changes in the fair value of the portfolio are
the result of changes in market conditions.



The fair value of
trading contracts, which represents the net unrealized gain and loss positions, is recorded as assets and liabilities, after applying the appropriate counterparty netting agreements. At March 31, 2004, the fair value of trading contract assets and
liabilities was $52.6 million and $122.5 million, respectively. At December 31, 2003, the fair value of energy trading contract assets and liabilities was $37.2 million and $102.6 million, respectively. As of March 31, 2004, the remaining trading
portfolio fair value is comprised primarily of interest rate swap agreements.



The following table disaggregates the net fair value of contract assets and liabilities, excluding AE Supplys generating assets and power sales agreements with its regulated utility affiliates for their
provider-of-last-resort (PLR) obligations, as of March 31, 2004, based on the underlying market price source and the contract delivery periods.

In the table above,
each contract is classified by the source of fair value, based upon the individual settlement dates within an entire contract. Therefore, portions of a single contract may be assigned to multiple classifications based upon the source of the
underlying market prices used to determine the fair value of the contract. AE Supply determines prices actively quoted from various industry services, broker quotes, and the New York Mercantile Exchange (NYMEX). Electricity markets are generally
liquid for approximately one year and most natural gas markets are generally liquid for approximately three years. Afterward, some market prices can be observed, but market liquidity is less robust.



The most significant variables to AE Supplys models used to value these
contracts are the forward prices for both electricity and natural gas. These forward prices are based on observable market prices to the extent prices are available in the market. Generally, electricity forward prices are actively quoted for about
one year, and some observable market prices are available for about three years. After three years, the forward prices for electricity are based on the forward price of natural gas and a marginal heat rate for generation (based on more efficient
natural gas-fired generation) to convert natural gas into electricity. For natural gas, forward prices are generally actively quoted for about three years, and some observable market prices are available for about five years. Beyond five years,
natural gas prices are modified, based on trends in prior years. The fair value of AE Supplys contracts classified above as prices based on models was a net asset of $2.7 million.



For deliveries of less than one year, the fair value of AE Supplys contracts was a net asset of $1.7 million.

Affiliated:  Affiliated revenues increased $8.4 million primarily due to increased sales volume at higher average prices charged to the Distribution Companies in accordance with the long-term power sales agreements
between AE Supply and the Distribution Companies.

Operating Expenses



Fuel consumed in electric
generation:  Total fuel consumed in electric generation increased $7.6 million due primarily to a $14.5 million increase in the cost of fuel consumed at the gas-fired generating stations, including the amount attributable to
increased energy production from AE Supplys generating facility in Springdale, Pennsylvania which became operational in July 2003. Additionally, coal expenses decreased in the first quarter of 2004, principally due to the decrease in coal
consumed at Hatfields Ferry Unit No. 2 and Pleasants Unit No. 1.

##### Table of Contents

Purchased power and transmission:  Purchased power and transmission expense
decreased approximately $13.2 million primarily as a result of Monongahela Power having less generation available for sale to AE Supply under contractual arrangements due to Hatfields Ferry Unit No. 2 and Pleasants Unit No. 1 being off-line
during all or part of the first quarter of 2004.



Operations and maintenance:  Operations and maintenance expense decreased by $84.6 million primarily due to 2003 costs which did not recur or were significantly lower than 2003. These included a $33.5 million
decrease in impairment charges associated with assets held for sale, a $20.8 million decrease in third party consulting costs, a decrease in asset retirement costs of $8.4 million related to the Gleason and Mitchell facilities, a decrease of $7.0
million as a result of lower charges for litigation reserves, and a $5.3 million decrease in SERP and disability costs.



Depreciation and amortization:  Depreciation and amortization expense increased $4.8 million primarily related to the generating
facility in Springdale, Pennsylvania, which became operational in July 2003, and the installation of environmental control equipment at Pleasants Units No. 1 and No. 2.



Taxes other than income taxes:  Taxes other than income taxes decreased $3.1 million primarily due
to a settlement of certain prior years property tax assessment issues.



Interest Expense



Interest expense increased
$26.4 million primarily due to an increase in AE Supplys average long-term debt outstanding and the write-off of $13.9 million of the 2003 refinancing issuance costs as a result of the March 2004 refinancing. The first quarter 2004 results do
not reflect a full quarter of lower interest expense as a result of the March 2004 refinancing which closed on March 8, 2004.



Additionally, capitalized interest decreased by $4.2 million related to the generating facility in Springdale, Pennsylvania, which became operational in
July 2003.



Income Tax Benefit



The effective income tax rates for the three months ended March 31, 2004 and
2003 were 21.1 percent and 38.8 percent, respectively. The change in the effective tax rate was a result of increased consolidated savings and depreciation adjustments.



Allegheny allocates income tax expense or benefit to its subsidiaries pursuant to its consolidated tax sharing agreement.
This corporate allocation may cause significant fluctuations in the effective quarterly tax rates from the statutory rates for the subsidiaries depending on the level of pre-tax profitability.



Cumulative Effect of Accounting Changes, Net



The following items were recorded in the first quarter of 2003:



Effective January 1, 2003, Allegheny adopted EITF Issue No. 02-3. As a
result, AE Supply recorded a charge against earnings, as the cumulative effect of a change is accounting principal of $12.2 million, net of income taxes ($19.7 million, before income taxes), representing the fair value of those contracts previously
accounted for under EITF Issue No. 98-10, Accounting for Contracts Involved in Energy Trading and Risk Management Activities, that no longer qualify for mark-to-market accounting.



Effective January 1, 2003, Allegheny adopted SFAS No. 143. As a result, AE
Supply recorded a charge against earnings as the cumulative effect of a change in accounting principle of $7.4 million, net of income taxes ($11.9 million, before income taxes). See Note 12, Asset Retirement Obligations, above, for additional
information.

Monongahelas
net income decreased $50.9 million for the three months ended March 31, 2004 as compared to the same period in 2003. The decrease was primarily due to earnings of the Generation and Marketing segment for the three months ending March 31, 2003 as a
result of the recognition of a $48.1 million gain, net of income taxes ($61.7 million, before income taxes), for the reapplication of the provisions of SFAS No. 71, which did not recur in the same period of 2004.



Operating Revenues



Total operating revenues for the three months ended March 31, 2004 and 2003 were as follows:

For the three months
ended March 31, 2004, the Delivery and Services segments retail electric revenues increased $2.9 million as compared to the same period in 2003, primarily due to an increase in residential, commercial, and industrial sales which were partially
offset by a 5.2 percent decrease in heating degree days as a result of warmer winter weather. Average heating degree days for the three months ended March, 31, 2004 were 2.2 percent lower than normal.



For the three months ended March 31, 2004, the Delivery and Services
segments retail natural gas revenues increased $29.0 million as compared to the same period in 2003, primarily due to an increase in a retail tariff effective October 2, 2003 to cover the increase in purchased gas costs. This increase was
partially offset by a combined 10.0 percent decrease in residential, commercial, industrial, and wholesale gas sales as a result of warmer winter weather.

For the three months ended March 31, 2004, the Delivery and Services segments bulk power revenues
decreased $3.1 million as compared to the same period in 2003, primarily due to lower gas wholesale revenues as a result of warmer winter weather and, to a lesser extent, contract expirations.



The Generation and Marketing segments affiliated and other revenues
decreased $10.0 million for the three months ended March 31, 2004 as compared to the same period in 2003, primarily due to decreased sales of energy to the Delivery and Services segment as a result of Hatfields Ferry Unit No. 2 and Pleasants
Unit No. 1 being off-line during all or part of the first quarter of 2004.



Operating Expenses



Fuel consumed in
electric generation:  Fuel consumed in electric generation, which relates entirely to the Generation and Marketing segment, represents the cost of coal, natural gas, and oil burned at Monongahelas generating stations to
produce electricity. For the three months ended March 31, 2004, fuel consumed in electric generation decreased $4.4 million as compared to the same period in 2003, primarily due to a 12.6 percent decrease in the quantity of electricity produced
resulting from Hatfields Ferry Unit No. 2 and Pleasants Unit No. 1 being off-line during all or part of the first quarter of 2004. This decrease was partially offset by a small increase in coal prices.



Purchased power and transmission:  Purchased power
and transmission expense for the three months ended March 31, 2004 and 2003 consists of the following items:

The Delivery and
Services segments purchased power from PURPA generation decreased $4.4 million for the three months ended March 31, 2004 as compared to the same period in 2003. The decrease in the PURPA generation expense was primarily due to plant outages
and a 7.0 percent decrease in MWhs generated.



The eliminations
are necessary to remove the effect of affiliated purchased energy and transmission expenses.



Cost of utility gas sold:  Cost of utility gas sold, which relates entirely to the Delivery and Services segment, decreased $5.5
million for the three months ended March 31, 2004, as compared to the same period in 2003, primarily due to a 12.5 percent decrease in gas purchases which was partially offset by a 7.8 percent increase in gas prices.



Deferred energy costs, net:  The increase in
deferred energy costs, net, of $31.4 million for the three months ended March 31, 2004 is primarily due to higher natural gas prices for the West Virginia operations, which are expected to be recovered through customer rates.

##### Table of Contents

Operations and maintenance:  Operations and maintenance expense for the three
months ended March 31, 2004 decreased $8.1 million primarily due to lower employee benefit and insurance expenses. The decrease in employee benefit expense was primarily due to a reduction in disability expense and a reduction in SERP expense due to
decreased curtailment, termination and settlement charges in the three months ended March 31, 2004. The decrease in insurance expense for the three months ended March 31, 2004 was primarily due to the recording of additional reserves for injury and
damages and unrecoverable damages for an ice storm for the three months ended March 31, 2003.



Taxes other than income taxes:  Taxes other than income taxes increased $3.9 million for the three months ended March 31, 2004, as compared to the same period of 2003, primarily as a result of
increased West Virginia business and occupation taxes partially offset by lower payroll taxes.



Other Income, Net



Other income, net, represents non-operating income and expenses before income taxes. Other income, net, for the three months ended March 31, 2004 decreased $61.8 million from the three months ended March 31, 2003, primarily due to the
recognition of a $61.7 million gain related to the reapplication of the provisions of SFAS No. 71 to generation assets in West Virginia that was recorded in the first quarter of 2003.



Income Tax Expense



The effective income tax rates for the three months ended March 31, 2004 and 2003 were 46.3 percent and 28.0 percent, respectively.The change in
the effective income tax rate for the three months ended March 31, 2004 is primarily a result of the tax benefit of the reapplication of SFAS No. 71 recognized in the first quarter of 2003, which did not recur in 2004.



Allegheny allocates income tax expense or benefit to its subsidiaries
pursuant to its consolidated tax sharing agreement. This corporate allocation may cause significant fluctuations in the effective quarterly tax rates from the statutory rates for the subsidiaries depending on the level of pre-tax profitability.

POTOMAC EDISONS RESULTS OF OPERATIONS



Income Summary



Potomac Edisons net income decreased $9.7 million for the three months ended March 31, 2004, as compared to the same
period of 2003. This decrease was primarily due to the recognition, during the first quarter of 2003, of an $8.6 million gain, net of income taxes ($14.1 million, before income taxes), for the reapplication of the provisions of SFAS No. 71, and a
$1.9 million gain on the sale of land offset by applicable income taxes.



Operating Revenues



Operating revenues
decreased $7.0 million for the three months ended March 31, 2004 as compared to the same period in 2003. The decrease in operating revenues was due to a $4.8 million reduction in revenues from the loss of four wholesale customers resulting from
contract expirations and a reduction of $5.6 million resulting from an 8.9 percent lower average rate per MWh charged to industrial customers. Operating revenues were also lower as a result of a 3.6 percent decrease in the number of heating degree
days during the period ended March 31, 2004 as compared to the same period in 2003. These reductions in revenue were partially offset by a 0.5 percent increase in the rates charged per MWh to residential customers and 1.4 percent increase in the
rates charged to commercial customers for the period ended March 31, 2004. Additionally, there were slight increases in the average number of residential, commercial, and industrial customers served of 1.7 percent, 2.1 percent and 1.5 percent,
respectively, for the period ended March 31, 2004.



Operating Expenses



Purchased power and
transmission:  Purchased power and transmission expense for the three months ended March 31, 2004 was $7.7 million lower than those for the three months ended March 31, 2003. Approximately $2.5 million of the reduction in expenses
was a result of lower volume due to the loss of four wholesale customers in 2004, as well as a lower number of heating degree days in 2004 compared to 2003. Approximately $4.9 million of the decrease was a result of reduced rates and approximately
$2.4 million was due to lower costs of the market-based pricing component of electricity purchased from AE Supply. These reductions were partially offset by approximately $1.1 million of higher purchased power expenses and $1.0 million of increased
costs of transmission services for the period due to increases in PURPA generation.



Operations and Maintenance:  Operations and maintenance expense for the three months ended March 31, 2004 decreased $1.2 million as compared to the same period in 2003, primarily
due to insurance expense related to February 2003 ice storm deductibles which were recorded in the three months ended March 31, 2003.



Other Income, Net



Other income, net, represents non-operating income and expenses before income taxes. Other income, net, decreased $16.8 million for the three months ended
March 31, 2004, as compared to the same period in 2003, primarily due to the recognition, during the first quarter of 2003, of a $14.1 million gain related to the reapplication of the provisions of SFAS No. 71 and a $1.9 million gain on the sale of
land.



Income Tax Expense



The effective income tax rates for the three months ended March 31, 2004 and
2003 were 35.6 percent and 34.0 percent, respectively. The change in the effective income tax rate for the three months ended March 31, 2004 is primarily due to the effect of regulation on deferred income taxes for depreciation, and allocated
consolidated tax benefits.



Allegheny allocates income tax
expense or benefit to its subsidiaries pursuant to its consolidated tax sharing agreement. This corporate allocation may cause significant fluctuations in the effective quarterly tax rates from the statutory rates for the subsidiaries depending on

WEST PENNS RESULTS OF OPERATIONS



Income Summary



Net income increased $7.2 million for the three months ended March 31, 2004, as compared to the same period of 2003. The net
increase was primarily due to an increase in other income, net, during 2004 resulting from a $6.6 million gain on the sale of land which did not occur in 2003, and $1.4 million in decreased interest expense partially offset by $2.6 million increased
income tax expense resulting from increased pre-tax income.



Operating
Revenues



Operating revenues increased $9.3 million for
the three months ended March 31, 2004 as compared to the same period in 2003 primarily due to increased revenue from residential customers of $3.4 million and increased revenue from commercial and industrial customers of $6.0 million. The increase
in residential revenues was primarily the result of a 2.2 percent increase in usage. The increase in commercial and industrial revenues was primarily the result of usage increases of 2.5 percent and 0.8 percent, respectively. Overall usage increased
primarily as a result of a 0.5 percent increase in the average number of customers served. The operating revenue increase was adversely impacted by a 6.1 percent decrease in heating degree days.



Operating Expenses

for the three months ended March 31, 2004 as compared to the same period in 2003, primarily as a result of increased affiliated purchased power expense of $17.5 million. The increase in affiliated purchased power is due to increased volume resulting
from an increased average number of customers served and price increases.



Operations and maintenance:  Operations and maintenance expense decreased $3.5 million for the three months ended March 31, 2004 as compared to the same period in 2003, primarily as a result of
decreased salary and benefits expense of $2.6 million and decreased outside services expense of $1.5 million and insurance expenses related to deductibles for a February 2003 ice storm.



Depreciation and amortization:  Depreciation and amortization expense decreased $1.4 million during
the three months ended March 31, 2004 as compared to the same period in 2003, primarily as a result of $1.0 million of decreased amortization related to intangible software.



Other Income, Net:  Other income, net, represents non-operating income and expenses before income
taxes. Other income, net, increased $7.0 million for the three months ended March 31, 2004 as compared to the same period in 2003, primarily due to a $6.6 million gain from the sale of land.



Interest Expense:  Interest expense decreased $1.4
million for the three months ended March 31, 2004 as compared to the same period in 2003, primarily due to lower average debt levels resulting from the repayment of transition bonds.



Income Tax Expense



The effective income tax rates for the three months ended March 31, 2004 and 2003 were 29.3 percent and 29.5 percent, respectively.

AGCS RESULTS OF OPERATIONS



Income Summary



Net income increased $2.1 million primarily due to decreases in interest expense and income tax expense. Interest expense decreased $1.3 million as result
of the repayment of $25.0 million and $50.0 million of long-term debt in June 2003 and September 2003, respectively. Income tax expense decreased by $0.6 million due to increased consolidated savings, increased depreciation resulting from a state
tax benefit for bonus depreciation, and the receipt of a prior period refund. These items resulted in an effective income tax rate of 18.3 percent for the three months ended March 31, 2004 compared to 31.1 percent for the same period in 2003.



Allegheny allocates income tax expense or benefit to its
subsidiaries pursuant to its consolidated tax sharing agreement. This corporate allocation may cause significant fluctuations in the effective quarterly tax rates from the statutory rates for the subsidiaries depending on the level of pre-tax
profitability.



FINANCIAL CONDITION, REQUIREMENTS, AND
RESOURCES



Liquidity and Capital Requirements



To meet cash needs for operating expenses, the payment of interest,
retirement of debt, and acquisitions and construction programs, Allegheny and its subsidiaries have used internally generated funds (net cash provided by operations less common and preferred dividends) and external financings, including the sale of
common and preferred stock, debt instruments, installment loans, and lease arrangements. The timing and amount of external financings depend primarily upon anticipated cash needs, and capital structure objectives of Allegheny.



On March 8, 2004, AE and AE Supply refinanced approximately $1.7 billion the
amount of long-term debt outstanding at December 31, 2003 under the Borrowing Facilities (except for the A-Notes related to AE Supplys St. Joseph, Indiana generating project) with new borrowings in an aggregate amount of $1.55 billion. These
new borrowings are comprised of secured Term B Loans and a secured Term C Loan (collectively, the AE Supply Loans) at AE Supply, in the aggregate amount of $750 million and $500 million, respectively, and unsecured revolving and term
loan facilities at AE in the aggregate amount of $300 million (the New AE Facility, collectively with the AE Supply Loans, the New Loan Facilities). See Note 2, Long-Term Debt, above for additional information, See also Item
8, Note 3, Capitalization, to Alleghenys Annual Report on Form 10-K for the year ended December 31, 2003 for additional information concerning the refinancing and the debt covenants related to the New Loan Facilities.



Off-Balance Sheet Arrangements



The registrants do not have off-balance sheet arrangements that have, or are
reasonably likely to have, a current or future material effect on their financial condition, revenues, expenses, results of operations, liquidity, capital expenditures, or capital resources.



Long-Term Debt



See Note 2, Long-Term Debt, above for additional information and details regarding Alleghenys debt. See also Item 8,
Note 3, Capitalization, to Alleghenys Annual Report on Form 10-K for the year ended December 31, 2003 for additional details and discussion regarding debt covenants, refinancings and other debt issuances and redemptions.



Under the New AE Facility, AE has obtained a $300 million credit facility
which is comprised of a $100 million term loan and a $200 million revolving credit facility. The revolving credit facility contains a sub-facility wherein a maximum of $100 million of letters of credit may be outstanding at any given time. At March
31,

2004, there was $100 million outstanding under the term loan and $125 million outstanding under the revolving credit facility, of which $25 million
represented outstanding letters of credit. Accordingly, AE had available revolving credit capacity of $75 million, of which the entire amount was available either as revolving credit or for the issuance of letters of credit.



Allegheny has various obligations and commitments to make future cash
payments under contracts such as debt instruments, lease arrangements, fuel agreements, and other contracts. The table below provides a summary of the payments due by period for these obligations and commitments as of March 31, 2004. This table does

Financing



Debt:  For the three months ended March 31, 2004, the following issuances and redemptions of debt were made by the registrants:



|              |  |           |         |             |   |          |

Short-term
Debt:  Allegheny and AE Supply manage short-term obligations with cash-on-hand and amounts available under revolving credit facilities. Monongahela, Potomac Edison, and West Penn manage short-term obligations through an internal
money pool or cash-on-hand. As a method to accommodate intercompany short-term borrowing needs to the extent that certain companies have funds available, the money pool provides funds to approved Allegheny subsidiaries at the lower of the previous
days Federal Funds Effective Interest Rate, as quoted by the Federal Reserve, or the previous days seven-day commercial paper rate, as quoted by the same source, less four basis points.



At March 31, 2004, no registrant had access to any short-term revolving
credit facilities or lines of credit with third party financial institutions, beyond those which have been utilized. As mentioned above, AE had $75 million of revolving credit available under its $200 million revolving credit facility, which is
classified as long-term debt in accordance with its terms. Approximately $53.6 million of the total $55 million revolving credit facility at Monongahela is classified as current. See Item 8, Note 3, Capitalization, to Alleghenys 2003 Annual
Report on Form 10-K, for additional information.



OTHER
MATTERS



Critical Accounting Policies



A summary of Alleghenys critical accounting policies is included under
Item 7, Managements Discussion and Analysis of Financial Condition and Results of Operations in the 2003 Annual Report on Form 10-K filed by Allegheny, AE Supply, Monongahela, Potomac Edison, West Penn, and AGC. Alleghenys critical
accounting policies have not changed materially from those reported in the 2003 Annual Report on Form 10-K.



REGULATORY MATTERS



See Rate Matters and Regulatory Matters Affecting Allegheny in Item 1 of Alleghenys 2003 Annual Report on Form 10-K for additional information.



State Legislation and Regulatory Developments



Maryland:  The Maryland General Assembly enacted
Senate Bill 869 in its recently concluded 2004 session, which, if signed by the Governor, will implement a renewable energy portfolio standard in Maryland. Beginning in 2006, or upon the expiration of the transition period for any particular
customer class served by a supplier, whichever is later, retail electricity suppliers in Maryland will have to provide certain percentages of their energy supply from renewable energy resources. The legislation provides that if renewable resources
are too expensive, or unavailable in quantities sufficient to meet the standard in any given year, suppliers can opt instead to pay a compliance fee. The legislation directs the Maryland Public Service Commission to allow standard offer
service suppliers actual dollar for dollar recovery of costs incurred to comply with the legislation, including compliance fees if incurred, as described above.

Virginia:  In 2001, Potomac Edison filed an
application with the Virginia State Corporation Commission (Virginia SCC) to transfer management and control of its transmission facilities to PJM. The Distribution Companies transferred functional control over their transmission systems to PJM,
effective April 1, 2002. In July 2002, the Virginia SCC staff issued a report observing that Potomac Edisons application met each of Virginia SCCs rules for electric utilities to join a regional transmission organization (RTO), but to
date a decision has not been issued. Additionally, the Virginia General Assembly, in its 2003 legislative session, enacted a bill precluding electric utility companies such as Potomac Edison from transferring ownership or control of, or
responsibility to operate, any portion of any transmission system located in the Commonwealth to an RTO prior to July 1, 2004. The effect of this legislation on Potomac Edison is unclear. On April 9, 2004, the Virginia SCC issued an order directing
Potomac Edison to file a cost/benefit analysis on its membership in PJM by June 18, 2004, and scheduled a hearing on the matter for September 28, 2004.



Virginia recently enacted legislation to extend its capped rate period for an additional three and one-half years (through December 31, 2010) at the
current capped rate levels. The new legislation provides that electric companies that have sold or transferred their generating facilities, such as Potomac Edison, would be allowed a one-time opportunity to file for a rate increase between July 1,
2007 and December 31, 2010. The legislation also allows Potomac Edison to utilize adjustment provisions for the recovery of increases in the cost of purchased power beginning on July 1, 2007. We cannot predict what effect this new legislation might
have on Potomac Edison.



Rate Matters



Transmission:  In November 2003, the
FERC issued a series of orders related to transmission rate design for the PJM and Midwest regions. Specifically, the FERC found that the payment of multiple and additive (i.e., pancaked) rates for movement of power between PJM and the Midwest
region is not just and reasonable. The FERC ordered the elimination of pancaked rates and the implementation of a transitional rate design for a two-year period, and ordered the parties to develop a long-term rate design solution. In a settlement
submitted to the FERC on March 5, 2004, the parties have agreed to continue pancaked rates through December 1, 2004, and to forego a transitional rate design. A long-term rate design solution would be implemented on December 1, 2004. On March 22,
2004, the FERC issued an order accepting the settlement. While the long-term rate design is intended to keep transmission owners neutral with respect to transmission revenues and to minimize the shifting of costs, there is no assurance that this
will be the actual result. Allegheny cannot predict the financial impact the long-term rate design will have on its transmission revenues or the Distribution Companies transmission costs.



|ITEM 3. |  | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- |  | ----------------------------------------------------------



Alleghenys primary market risk exposures are associated with interest rates and commodity prices. Allegheny has risk management policies to monitor
and assist in controlling these market risks and uses derivative instruments to manage some of the exposures.



A summary of Alleghenys market risks is included under Item 7A, Quantitative and Qualitative Disclosures About Market Risk, in the 2003 Annual
Report on Form 10-K filed by Allegheny, AE Supply, Monongahela, Potomac Edison, West Penn, and AGC. Alleghenys market risks have not changed materially from those reported in the 2003 Annual Report on Form 10-K.



As reported in the 2003 Annual Report on Form 10-K, Allegheny and AE Supply
use various methods to measure their exposure to market risk on a daily basis, including a value at risk model (VaR). Allegheny calculates VaR using the full term of all remaining positions being marked-to-market. This calculation is based upon
managements best estimates and modeling assumptions, which could materially differ from actual results. As of March 31, 2004 and December 31, 2003, this calculation yielded a VaR of $0.8 million and $0.2 million, respectively. The increase in
the VaR during the first quarter of 2004 is primarily a result of increases in both the volatility and absolute level of forward market power prices.

|ITEM 4. |  | CONTROLS AND PROCEDURES
|------- |  | -----------------------



In August 2002, Alleghenys independent auditor, PricewaterhouseCoopers LLP (PwC), advised Allegheny that it considered Alleghenys internal
controls to have material weaknesses, principally relating to trading operations and related information systems. In the third quarter of 2002, Allegheny initiated a comprehensive review of its financial information. In March 2004, PwC advised
Alleghenys Audit Committee that although management has made significant progress in addressing the specific control weaknesses previously identified, not all of these deficiencies have been remedied and certain internal control material
weaknesses remain. Alleghenys management, Audit Committee, and Board of Directors are fully committed to resolving Alleghenys internal control deficiencies. Ultimate resolution of the deficiencies will include a focus on accountability
and strict, timely adherence to a set of sound internal control policies and procedures.



Allegheny has implemented corrective actions to mitigate the risk that its internal control deficiencies would prevent information required to be disclosed by Allegheny in its periodic reports, including this
quarterly report, from being timely reported or impede the compilation and communication of information to Alleghenys management sufficient to permit timely decisions regarding required disclosures in the financial statements and other
information included in its periodic reports, including this quarterly report. These actions include the continued development and implementation of new internal control policies, processes, and procedures to identify and remediate weaknesses and
improve controls. Allegheny is continuing to implement and install new transaction processing systems and to enhance existing systems for front-, middle-, and back-office areas for its energy trading operations.



Before December 31, 2004, Allegheny expects that it will have restored the
effectiveness of its internal controls and will no longer need to rely on the performance of additional procedures to ensure the accuracy and completeness of its financial statements.



To address the weaknesses identified in Alleghenys internal controls and disclosure practices, Allegheny substantially
augmented and revised its procedures in connection with the preparation of its 2002 annual report, and has employed these procedures in connection with the preparation of each subsequently filed periodic report, including this quarterly report.
These augmented procedures include a formal drafting group to comprehensively review, revise and update disclosures. This exercise also includes direct involvement by senior officers, including the Chief Executive Officer and the Chief Financial
Officer. The principal elements of these augmented procedures have formed the basis for Alleghenys written disclosure controls and procedures applicable to periodic reports and certain public communications.



In 2003, Allegheny created a Disclosure Committee, which is chaired by
Alleghenys General Counsel and is comprised of executives, including Alleghenys Chief Risk Officer, Vice President and Controller, Director of Audit Services and Vice President, Corporate Communications, as well as the senior officers
responsible for Alleghenys business segments. The Disclosure Committee establishes, maintains, monitors and evaluates Alleghenys written disclosure controls and procedures, and supervises and coordinates the preparation of
Alleghenys periodic reports and certain other of its public communications pursuant to formal written disclosure controls and procedures.



The Disclosure Committee, with the participation of Alleghenys management, including the Chief Executive Officer and Chief Financial Officer,
reviewed, in accordance with Exchange Act Rules 13a-15(e) and 15d-15(e), the augmented procedures implemented by Allegheny in connection with the preparation of this report as of March 31, 2004 and found them to be effective. However, until
Allegheny completes the actions described above to remedy internal controls deficiencies, Allegheny intends to devote additional resources to ensure that its public disclosures are accurate.



The above matters have been undertaken by Allegheny at the direction and with
the oversight of the Audit Committee of the Board of Directors and with extensive involvement of PwC and other outside professional services firms.
