Due to the tight 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 will inform the implementation plan of rolling blackouts on and after
March 28, 2011 as follows:
