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.
