Due to the tight power supply-demand balance, TEPCO has been implementing 
rolling blackouts 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 
April 2, 2011 as follows:

○ Implementation plan of rolling blackout from April 2 (Sat) to April 4 
   (Mon)
On April 2, Saturday, no rolling blackout will be implemented in any time 
periods based on the today's power demand, the weather forecast tomorrow 
on April 2 and the trend of the power supply.
Also on April 3 and 4, no rolling blackout will be implemented in any time 
periods based on the most recent power demand and the trend of the power 
supply.
Because of your cooperation in conserving electricity, we can avoid the 
rolling blackout for tomorrow from April 2 to April 4. We appreciate your 
continuous cooperation

○ Implementation plan of rolling blackouts on April 5 (Tue)- April 8 (Fri) 
 Please refer to the appendix 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]
   ● In order to prevent fires, please make sure to switch off electric 
      appliances such as hair driers when you leaving home.
   ● Please carefully pay attention to the traffic at the crossings in 
      case the traffic lights are suddenly turned off.
   ● As for the buildings and apartments, please be aware that equipments 
      and facilities such as elevators, automatic doors, automatic locks, 
      and multilevel parking lots will not function. In particular, please 
      avoid using elevators during the scheduled blackouts.

 ○Prediction of demand and supply from April 1 to April 4


* Prediction of demand
April 2: Since the temperature is forecasted to be higher than normal and 
         it is Saturday, we assume the estimated peak demand on April 2 
         will be 32,000MW, which is lower than that of today April 1.
April 3: Since the temperature is forecasted to be lower than normal, we 
         assume the estimated peak demand on April 3 will be 34,000MW, 
         which is higher than that of April 2.
April 4: Since the temperature is forecasted to be lower than normal, we 
         assume the estimated peak demand on April 4 will be 36,500MW, 
         which is higher than that of today April 1.

* Estimated demand and supply capacity may change depending on the 
  situation of the day.
