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.

○Implementation plan of rolling blackout from Saturday, March 19 to 
Monday, March 21.
Regional blocks are not scheduled on 19th March considering today's 
electricity supply-demand.
Regional blocks on 20th March will be informed on 19th March considering 
tomorrow's electricity supply-demand.
Regional blocks on 21th March will be informed on 20th March considering 
electricity supply-demand.
Please refer to the appendix for details. The actual blackout period for 
each block is planned to be maximum 3 hours during the relevant scheduled 
time period. 
For customers who will be subject to rolling blackout, please be prepared 
for the announced blackout periods. Also for customers who are not 
subject to blackouts, we would appreciate your continuous cooperation in 
reducing electricity usage by turning off unnecessary lightings and 
electrical equipments. 

●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. Moreover, 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.

[Improvement in implementing planned blackouts]

  from the customers' point of view.
