With at least two, possibly three, of Japan’s major nuclear power plants damaged by Friday’s earthquake and subsequent tsunami, electricity supply within the island nation is precarious and the utility company has asked companies and individuals to limit their consumption.

A statement from Tokyo Electric Power Company (Tepco) says that, because of the 11 March earthquake in the northern part of Japan, its facilities have been seriously damaged and power shortages may occur.
“Tepco appreciates customers’ co-operation in reducing electricity usage by avoiding using unnecessary lighting and electrical equipment,” the statement reads.
“We are taking all measures to restore power. However, we expect an extremely challenging situation in power supply for a while. We kindly ask our customers to co-operate with us in reducing usage of power.”
One of Japan’s biggest ICT manufacturers, Toshiba, has announced that it is co-operating with Tepco’s request to cut electricity consumption by operating only those of its businesses related to the provision of essential services required for social and economic activities.
“This decision extends to Toshiba Group companies and covers production facilities and business premises in areas where Tepco plans controlled power outages,” the company states.
To this end, Toshiba today closed all its facilities in those areas experiencing power outages, other than its headquarters and operations related to essential services.
