Item 5.  Other Events

         On May 24, 2004,  FirstEnergy Nuclear Operating Company, a wholly owned
subsidiary of FirstEnergy Corp., announced that the 1,260-megawatt Perry Nuclear
Power Plant is expected to return to service next week,  following repairs to an
emergency service water pump.

         The plant was removed  from  service on Saturday  May 22,  2004,  after
routine testing indicated that the pump was not maintaining a normal flow level.
An  initial  inspection  found a broken  coupling  on the  pump's  shaft,  and a
complete review is under way.

         A new pump and new  couplings,  made of  stronger  material,  are being
installed to help ensure  better  reliability.  The plant will return to service
after  the  equipment  has  been  thoroughly  tested  and the  review  has  been
completed.

         The combined  ownership  and  leasehold  interests in the Perry Nuclear
Power Plant are: The  Cleveland  Electric  Illuminating  Company - 44.85%;  Ohio
Edison Company - 30.00%;  The Toledo Edison Company - 19.91%;  and  Pennsylvania
Power Company - 5.24%.

         A copy of the press  release  is  attached  as Exhibit 99 hereto and is
incorporated by reference.

but  are  not  limited  to,  the  terms  "anticipate,"   "potential,"  "expect,"

due to the speed and nature of increased  competition  and  deregulation  in the

commodity market prices,  replacement  power costs being higher than anticipated

legislative   and   regulatory   changes   (including   revised    environmental
requirements),  adverse  regulatory  or  legal  decisions  and  the  outcome  of
governmental  investigations  (including  revocation  of  necessary  licenses or

availability  and operation of generating  units, the inability to accomplish or
realize anticipated benefits of strategic goals, the ability to improve electric
commodity  margins and to experience  growth in the distribution  business,  the
ability to access the public securities markets,  further investigation into the
causes of the August 14, 2003  regional  power outage and the outcome,  cost and
other effects of present and potential legal and administrative  proceedings and
claims related to that outage,  a denial of or material change to  FirstEnergy's
Application  related to its Rate Stabilization Plan, the risks and other factors
discussed  from  time  to  time  in the  registrants'  Securities  and  Exchange
