Press Release (Mar 17,2011)
Implementation plan of rolling blackout on and after Friday, March 18, 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.

○Implementation plan of rolling blackout on Friday, March 18
Considering today's electricity supply-demand, regional blocks and time 
periods for the planned blackout are as follows. 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. 

[Expected rolling blackout time periods in each region]
Block 1: 6:20 - 10:00 
Block 2: 9:20 - 13:00 
Block 3: 12:20 - 16:00 
Block 1: 13:50 - 17:30 
Block 4: 15:20 - 19:00 
Block 2: 16:50 - 20:30 
Block 5: 18:20 - 22:00 

●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.

○Implementation plan of rolling blackout from Saturday, March 19 to 
 Thursday, March 24
