Scheduled Blackouts and Energy Conservation Request

Scheduled Blackouts and Energy Conservation Request
3/13/2011 – Tokyo Electric Power Company Co. Ltd.

The earthquake that occurred off the coast of the Pacific Ocean in Tohoku region of Japan on the 11th of March has heavily impacted facilities such as the No. 1 and No. 2 Nuclear power plants in Fukushima as well as various other power plants and power distribution facilities. The Tokyo Electric Power Company is in an extremely critical situation in regard to maintaining the current demand for electricity in various regions.

So far Tokyo Electric Power Company has tried to provide a stable power supply to the best of our abilities through extra electrical supplies from other electric power companies. The Japanese Government has also called upon citizens and companies in Japan to conserve energy as much as possible.

However, considering the extremely critical situation of meeting the expected demand and to avoid unpredictable large-scale blackouts we will implement scheduled blackouts starting tomorrow. We have been trying to avoid blackouts to our upmost ability and therefore deeply apologize to all our customers for causing inconvenience and worries. The Tokyo Electric Power Company will be taking measures of the highest possible degree to work quickly towards restoring a stable supply of electricity to its customers.

*Please note: The exact times and boundaries of the blackouts are subject to change. Areas in Tokyo listed beyond Arakawa-ku are not scheduled to have blackouts, but are next to areas that have blackouts scheduled, and are therefore included on this list in case power outages extend past official city boundaries.
