FIRSTENERGY OHIO UTILITIES FILE TO ESTABLISH A

GENERATION CHARGE ADJUSTMENT RIDER

Akron, OH - FirstEnergy Corp.’s (NYSE: FE) Ohio electric utility companies - Ohio Edison, The Cleveland Electric Illuminating Company and Toledo Edison - today filed with the Public Utilities Commission of Ohio a request to establish a generation charge adjustment rider, as permitted under the companies’ previously approved Rate Stabilization Plan.

If approved, the rider would average $.002554 per kilowatt-hour, effective January 1, 2006, for all classes of customers. Residential customers’ riders would be $.002725 per kilowatt-hour, or $1.36 per month for those using 500 kilowatt-hours of electricity. For customers who are not served by alternative suppliers, the rider would be considered part of the generation charges for electricity. For customers who have switched suppliers, the generation shopping credit would increase by the same amount, providing a more favorable "price to compare."

The filing reflects projected increases in fuel and related costs in 2006 compared with 2002 costs. At the end of 2006, the rider would be reconciled with actual costs for the year, and could result in an upward or downward adjustment in the level of the rider and generation shopping credit in 2007. Under the filing, adjustments would be made annually, with final reconciliation, if necessary, being completed in 2009.

Market prices for coal - the largest component of the proposed increase - have risen substantially since 2002. However, FirstEnergy has entered into long-term supply contracts that provide a hedge against escalating prices, mitigating the effect of the increases. Other cost increases that were reflected in the filing include those for natural gas; nuclear fuel expenses and disposal; lime, stabilizers and other additives; and emission allowances.

The generation charge adjustment filing was made under FirstEnergy’s Rate Stabilization Plan, which enables the company to request recovery of increased fuel and related costs. The Rate Stabilization Plan provides customers with protection against price volatility during the period of 2006 through 2008 - essentially keeping rates at 1990 levels for Ohio Edison customers and 1996 levels for Cleveland Electric Illuminating and Toledo Edison customers. The plan also provides up to $10 million in support of economic development projects, and $8.75 million in energy-efficiency program support for low-income customers.

TO THE INVESTMENT COMMUNITY:¹

As detailed in today’s news release, FirstEnergy's regulated Ohio subsidiaries, Ohio Edison, The Cleveland Electric Illuminating Company and Toledo Edison ("Companies") filed with the Public Utilities Commission of Ohio ("PUCO") a request ("Application") to establish a generation charge adjustment rider. This letter provides additional details concerning today’s filing.

Background

The PUCO, as part of its approval of the Rate Stabilization Plan ("RSP") for the Companies last year, approved a mechanism to allow the Companies to recover increased fuel costs as compared to comparable fuel costs incurred during the base line year of 2002. Under the RSP, increased fuel costs arising during 2006-2008 may be recovered.

Application Details

This Application seeks to implement recovery of only the increased fuel costs applicable to retail customers of the Companies for 2006 through a tariff rider mechanism called the Generation Charge Adjustment Factor ("GCAF"). The GCAF is proposed to be calculated on an annual basis. Applicable retail customers include all tariff customers and those customers served on contracts that permit such increases. However, since the same GCAF will be part of the shopping credit, shopping customers will effectively bypass the GCAF charge.

The Companies request that the GCAF Rider be implemented on January 1, 2006 based upon expected fuel costs for 2006. The Companies also propose a reconciliation mechanism to ensure that the Companies do not overcollect or undercollect actual retail recoverable fuel costs.

¹Please see the forward-looking statement at the end of this letter

1

The baseline 2002 fuel costs ($10.816/MWh) and the estimated 2006 fuel costs ($13.370/MWh) are detailed in Exhibit 1 which is attached at the end of this letter. Market prices for coal - the largest component of the proposed increase - have risen substantially since 2002. However, FirstEnergy entered into long-term supply contracts that provide a hedge against escalating prices. As a result, the Companies have been able to mitigate such increases in the cost of coal during the same time period. Other cost increases that were reflected in the filing include those for natural gas, nuclear fuel expenses and disposal, lime, stabilizers and other additives, and emission allowances.

The process for determining the fuel costs and the reconciliation mechanism is summarized below:

• Total allowable fuel costs for the 2002 base line year are converted to a total allowable fuel cost rate shown in Exhibit 1 as dollars per MWh ($10.816/MWh) by dividing the total MWh generated into the total allowable fuel costs. Likewise, the total allowable estimated fuel costs for 2006 are also converted to dollars per MWh ($13.370/MWh).

• The difference between the 2006 allowable estimated fuel cost rate per MWh and the base line total allowable fuel cost rate per MWh is the total allowable fuel cost rate in excess of the 2002 base line year. Multiplying this rate differential by the 2006 retail sales of non-shopping customers on tariffs and on contracts that permit such price changes yields the allowable fuel costs in excess of the 2002 base line year that will be recovered from retail customers in 2006.

• Based upon the data in Exhibit 1 and projected 2006 Ohio retail sales to which the GCAF Rider will apply, the estimated revenue from the implementation of the GCAF Rider for the Companies is approximately $93 million for 2006.

• The Companies also are proposing a reconciliation component in the GCAF to be applicable in subsequent GCAF values (e.g., the GCAF for 2007 and 2008). This reconciliation component will equal the difference between actual recoverable retail fuel costs and revenues received from the application of the GCAF Rider. The 2006 GCAF Rider will contain no reconciliation component since it is based on all estimated costs.

Very truly yours,
