GPU merged with and into  FirstEnergy  and ceased its separate  existence.  This
filing includes the activity for the period January 1 through March 31, 2002 for
FirstEnergy  Generation  Corp.  (FirstEnergy  Generation)  which  is  an  exempt

      The undersigned,  FirstEnergy  hereby certifies pursuant to Rule 24 of the
Rules and Regulations  under the Public Utility Holding Company Act of 1935 (the
Act), that certain of the transactions proposed in the Applications, as amended,

with  the   conversion  of  a   construction   loan  to  a  term  loan  for  the

      In accordance with Orders dated July 6, 1995 and March 6, 1996 in SEC File
No. 70-8593, and in addition to the reimbursement agreements described in item 1
above, the following is reported:

1.    Financial Statements
      --------------------

      A  copy  of  FirstEnergy  Solutions  Corp.,  (FirstEnergy  Solutions)  GPU
Capital,  Inc.'s (GPU Capital) and GPU Power's  unaudited  Consolidated  Balance
Sheets as of March 31, 2002 and unaudited Consolidated  Statements of Operations
for the twelve  months  ended  March 31, 2002 will be filed  separately  under a
request for confidential treatment pursuant to Rule 104(b).

      FirstEnergy Solutions is a wholly-owned subsidiary of FirstEnergy and is a
natural gas and power marketer in both the wholesale and retail markets.

      GPU Capital was incorporated to secure financing to prepay indebtedness of
certain  subsidiaries  of GPU  Electric,  Inc. (GPU  Electric),  and for working
capital purposes including investments and acquisitions.  A capital contribution
was made to GPU Capital of all of the issued and outstanding common stock of GPU
Electric,  which then  became a  wholly-owned  subsidiary  of GPU  Capital.  GPU
Capital is a wholly-owned subsidiary of FirstEnergy.

      GPU Capital and GPU Electric  own and operate  electric  transmission  and
distribution  systems  outside the United States and will be referred to as "GPU
Electric."


2.    Investments in Exempt Entities
      ------------------------------

      In 1996, Avon Energy Partners Holdings,  Inc. (Avon) was formed to acquire
a 50% ownership  interest in Midlands  Electricity  plc  (Midlands),  an English
regional  electric  company.  A  wholly-owned  subsidiary of Avon  purchased the
outstanding  shares of Midlands  through a cash tender  offer of British  pounds
(BP) 1.7 billion  (approximately U.S. $2.6 billion).  FirstEnergy's  interest in
Avon is held by EI UK Holdings,  Inc. (EI UK), a wholly-owned  subsidiary of GPU
Electric.

      At the time of acquisition,  EI UK borrowed  approximately  BP 342 million
(approximately U.S. $586 million) through a five-year bank term loan facility to
fund its  investment in Holdings.  In addition to the amount  invested by EI UK,
Holdings  borrowed  approximately  BP 1.1 billion (U.S. $1.8 billion)  through a
non-recourse  term loan and revolving credit facility to provide for the balance
of the acquisition price.

      In July 1999, GPU Electric acquired the additional 50% ownership  interest
in Avon for BP 452.5 million (approximately US $714 million).  Accordingly,  GPU
Electric is the sole owner of Midlands'  electric  distribution  and contracting
businesses as well as independent  power plants  worldwide.  The acquisition was
financed  at that  time  through  a US $250  million  equity  contribution,  the
issuance of US $50 million of commercial paper by GPU Capital, and a two-year BP
245 million  (approximately US $357 million) credit agreement entered into by EI
UK.

       In March 2002, FirstEnergy announced that it had finalized terms of a
joint venture agreement with Aquila, Inc. (formerly Utilicorp United) for

                                       5




Aqulla to acquire partial ownership of Avon. Accordingly,  on May 8, 2002 Aquila
acquired  a 79.9  percent  interest  in  Avon  for  approximately  $1.9  billion
including  the  assumption  of $1.7  billion of debt.  FirstEnergy  (through GPU
Electric) and Aquilla  together will own all of the  outstanding  shares of Avon
through a jointly owned subsidiary, with each company having a 50 percent voting
interest.

      In 1999, GPU Electric acquired Empresa  Distribuidora  Electrica Regional,
S.A. (Emdersa),  an Argentine holding company, for $375 million. The acquisition
was  financed at that time  through  the  issuance  of  commercial  paper by GPU
Capital and a $50 million capital contribution.

       All of the acquisition  debt associated with  FirstEnergy's  ownership of
the above mentioned FUCOs has been retired.
