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 5, 2011 as follows:
○ Implementation plan of rolling blackout on April 5 (Tue)
On April 5, Tuesday, no rolling blackout will be implemented in any time
periods based on the today's power demand, the weather forecast tomorrow
on April 5 and the trend of the power supply.
Because of your cooperation in conserving electricity, we can avoid the
rolling blackout for tomorrow on April 5. We appreciate your continuous
cooperation.
○ Implementation plan of rolling blackouts from April 6 (Wed) to
April 11 (Mon)
Please refer to the appendix for details.
● The actual blackout period for each Group is planned to be up to
approximately 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 on April 4 and April 5

* Prediction of demand
Tomorrow on April 5, since the temperature is forecasted to be higher
than that of today, we assume the estimated peak demand on April 5 will
be 35,000MW, which is lower than that of today on April 4.
* Estimated demand and supply capacity may change depending on the situation
of the day.
