TEPCO has been implementing the rolling blackout since March 14 due to
the tightening power supply-demand balance caused by
the Tohoku-Taiheiyou-Oki Earthquake. We sincerely regret causing anxiety
and inconvenience to our customers and the society. We appreciate your
cooperation in conserving electricity consumption. 

At present, we have divided the area subject to the rolling blackout into
5 groups and announcing the schedule of blackout based on such groups.
Hereafter we plan to ramify each existing group further into
5 sub groups. (target implementation date: March 26 (Sat))

This is to enable our customer to predict the blackout more accurately as
the blackout is currently implemented within the group entirely and
partially depending on the actual demand-supply balance. 

For example, blackout will be implemented to entire group when
the demand-supply balance is tightening, while only part of the group 
will be subject to the blackout when the balance has improved.
Temporary improvement in the demand-supply balance is expected during
the spring time. 

Sub groups take turn for the blackout so that the unequal treatment among
customers will be avoided. 

TEPCO plans to introduce additional measures to improve our operation
such as the following example for the better announcement of blackout
forecast. (actual introduction will be determined after successfully
installing the group ramification. )

[forecast mark: example]
*blackout is scheduled, *there is a possibility of blackout, 
*NO blackout is scheduled

TEPCO will continue to do its utmost to secure the stable supply of
electricity. We apology for the inconvenience caused and appreciate your
continuous cooperation in conservation of electricity and your
understanding for the rolling blackout.
