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 23, 2011 as follows. 

○Implementation plan of rolling blackout on March 23 (Wed.)
Considering today's electricity supply-demand and tomorrow's weather, 
regional group and time periods for the planned blackout are as follows.

                     ···The necessity of the rolling blackouts 
                         will be judged depending on the supply-demand 
                         balance, and will be informed 2 hours before
                         the start of blackouts.

   3 hours during the relevant scheduled time period.
