April 30th, 2009, The Tokyo Electric Power Company Incorporated (TEPCO) announced 
that they have revised previous financial forecasts that were made in January 30th, 
2009, based on latest performance and related factors as outlined below.

Revision of Financial Forecasts
•Revision of the Year-end Financial Forecasts (April 1st, 2008-March 31st, 2009), 
 Consolidated


•Revision of the Year-end Financial Forecasts (April 1st, 2008-March 31st, 2009), 
 Non-consolidated


The Reason for the Revision
With regards to TEPCO's electricity business, operating revenue decreased due to 
a reduction of electricity sales volume. On the other hand, due to the reduction of 
fuel expense as well as efforts made to reduce maintenance and other expenses, 
operating income increased. Further, a reestimation of the restoration costs of 
Kashiwazaki-Kariwa Nuclear Power Station, yielded an increase in casualty loss 
from natural disaster and others. Given these changes, final revisions were made to 
our consolidated and non-consolidated financial projections.
