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 would like to inform the implementation plan of rolling blackouts on 
and after March 26, 2011 as follows. Since today, we will, in principle, 
inform each 5 sub-group divided from each existing 5 group (Group 1 to 5) 
on the rolling blackout plan on the following day. 

○Implementation plan of rolling blackout on March 26 (Sat.) and 
March 27 (Sun.) 
On March 26, Saturday, no rolling-blackout will be implemented in 
any time periods based on the today's power demand, the weather 
forecast on March 26 and the trend of the power supply.
On March 27, Sunday, no rolling-blackout will be implemented in any 
time periods based on the trend of the current power supply and demand.

○Implementation plan of rolling blackout on March 28 (Mon.) and 
April 1 (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.
