We would like to once again express our deep appreciation to all customers in the service area of ​​TEPCO Power Grid Inc. (hereinafter referred to as “TEPCO PG”).*, and society as a whole, for their cooperation yesterday (March 22) to save electricity in a context of tension between electricity supply and demand. We would also like to thank the private electricity providers who increased production and the companies that helped suppress demand, as well as the members of the media who helped spread the word about electricity savings, and the government officials and related agencies.

Thanks to your cooperation, we were able to avoid power cuts and pump water into the upper regulation reservoirs of the pumped storage hydroelectric power stations from last night until this morning. This has allowed us to increase the amount of remaining electricity that can be generated by pumped storage hydroelectric plants to 51% (as of 10 a.m. today), and given the current weather forecast, we expect that we have ensured sufficient supply.

However, some power plants in eastern Japan are still shut down following the earthquake off the coast of Fukushima prefecture on March 16, and weather conditions in the coming days could lead to a situation again. tight supply and demand.
We would like to ask our customers in the TEPCO service area to cooperate with the efficient use of electricity, for example by turning off unnecessary lighting and limiting the use of appliances, to the point where it does not hinder your daily life.
