Press Release (Mar 19,2011)
Implementation plan of rolling blackout on and after Sunday, March 20, 2011
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.
As for customers who will be subject to rolling blackout, please be 
prepared for the announced blackout periods. Also as 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 appliances.

○Implementation plan of rolling blackout on Sunday, March 20
Regional blocks are not scheduled on March 20th considering today's 
electricity supply-demand.

○Implementation plan of rolling blackout from Monday, March 21st to
26th, Saturday
Please refer to the appendix for details. 

●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.

[Others]
●In order to prevent fire, please make sure to switch off electric 
  appliances such as hair driers when you leaving home.
●Please pay attention to the traffic at the crossings in case the traffic 
  light may suddenly turn off.

[Improvement in implementing planned blackouts]
●In principle, we will implement the planned blackout based on the current 
  plan. However, we do realize that there is room for improvement. 
  Therefore, we will continue to consider and improve implementation plans 
  from the customers' point of view.
