Item 5.  Other Events

         As part of its informal inquiry, which began last September,  the U. S.
Securities  and  Exchange  Commission  has  requested in a letter dated June 24,
2004, that  FirstEnergy  Corp.  (Company)  voluntarily  provide  information and
documents related to an extended outage at the Davis-Besse Nuclear Power Station
(which  is owned by the  Company's  wholly  owned  subsidiaries,  The  Cleveland
Electric Illuminating Company and The Toledo Edison Company) that began in 2002.
The Company  intends to comply with this request and continue to cooperate fully
with this inquiry.


Forward-Looking  Statement:  This Form 8-K includes  forward-looking  statements
based on  information  currently  available to management.  Such  statements are
subject to certain risks and uncertainties.  These statements typically contain,
but  are  not  limited  to,  the  terms  "anticipate",   "potential",  "expect",
"believe",  "estimate" and similar words.  Actual results may differ  materially
due to the speed and nature of increased  competition  and  deregulation  in the
electric utility industry, economic or weather conditions affecting future sales
and  margins,  changes  in  markets  for energy  services,  changing  energy and
commodity market prices,  replacement  power costs being higher than anticipated
or  inadequately  hedged,  maintenance  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
operating   permits),   availability   and  cost  of  capital,   the  continuing
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,  the final outcome in the  proceeding  related to
the registrants'  Application for a Rate Stabilization Plan, the risks and other
factors discussed from time to time in the registrants'  Securities and Exchange
Commission filings,  including their annual report on Form 10-K (as amended) for
the year ended  December  31,  2003,  and their Form 10-Q for the quarter  ended
March 31, 2004, and other similar factors.  The registrants  expressly  disclaim
any current intention to update any forward-looking statements contained in this
document as a result of new information, future events, or otherwise.
