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 29, 2011 as follows:

○Implementation plan of rolling blackout on March 29 (Tues.) 
On March 29, Tuesday, no rolling blackout will be implemented in any time
periods based on the today's power demand, the weather forecast on March
29 and the trend of the power supply.

○Implementation plan of rolling blackout on March 30 (Wed.)- April 4(Mon.) 
 Please refer to the appendix 2 for details.

 ●The actual blackout period for each Group is planned to be maximum
  about 3 hours during the relevant scheduled time period.
 ●Each blackout period for each Group differs every day and starting
  and ending time of blackout periods may slightly differ.
 ●Depending on the supply-demand balance of the day, planned blackouts
  may not be carried out. In case the electricity supply-demand balance 
  becomes tighter than expected, we will reconsider the rolling blackout
  plan and inform you accordingly before we implement the revised plan.
 ●A blackout may occur in the adjacent areas where the planned blackouts
  are carried out

[Others]

  appliances such as hair driers when you leaving home.

  and facilities such as elevators, automatic doors, automatic locks, and
