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 from Saturday, March 19 to
Monday, March 21.
Regional blocks are not scheduled on 19th March considering today's
electricity supply-demand.
Regional blocks on 20th March will be informed on 19th March considering
tomorrow's electricity supply-demand.
Regional blocks on 21th March will be informed on 20th March considering
electricity supply-demand.
Please refer to the appendix for details. 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.
●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.
