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 24, 2011 as follows.

○Prediction of demand and supply on March 23
Estimated Demand 38,000 MW (18:00-19:00)
Supply Capacity 37,500 MW
○Prediction of demand and supply on March 24

*Prediction of demand
According to the weather forecast, the weather will become worse from
tomorrow afternoon and temperature will be lower than that of average
year. However, estimated temperature at peak demand time tomorrow will
be higher than that of today, so we assume estimated peak demand on
March 24 will be 37,000MW,which is lower than that of today.
*Estimated demand and supply capacity may change depending on the
situation of the day.
