Due to the power supply-demand balance, TEPCO has been implementing
rolling blackout since Monday, March 14. We sincerely regret causing
anxiety and inconvenience to our customers and the society. We appreciate
your cooperation in conserving electricity consumption.
For customers who will be subject to rolling blackouts, please be prepared
for the announced blackout periods. Also, for the customers who are not
subject to blackouts, we would appreciate your continuous cooperation in
reducing electricity usage by turning off unnecessary lightings and
electrical appliances.
We would like to inform the implementation plan of rolling blackouts on
and after March 25, 2011 as follows.

*Prediction of demand
According to the weather forecast, the temperature will be higher than
that of today. However, estimated temperature in the evening will be
lower due to rain, so we assume estimated peak demand on March 25 will
be 38,500MW,which is same as today.

situation of the day.
