The power supply capacity in TEPCO's service area is reaching its limit
in meeting the power demand because its power supply facilities including
power stations such as Fukushima Daiichi and Daini nuclear power stations
and transmission system have been seriously damaged due to
the Tohoku-Chihou-Taiheiyo-Oki Earthquake occurred on March 11th.
In this backdrop, we have notified our customers about the possibility of
rolling blackout this morning. However, because of the utilization of
UFR,we hereby notify our customers that we expect to be able to avoid
the rolling blackout tomorrow.
We continue to take all measures to recover facilities and secure power
supply. However, factoring in a difficult status of facilities, we may
be forced to implement rolling blackout from the next week.
We kindly ask our customers for continued cooperation in reducing usage
of needless lightning and electric appliances.
