The government on Friday asked four power utilities to make plans for rolling blackouts from July in case power demand reaches 99% of capacity.
The Ministry of Economy, Trade and Industry instructed the four companies—Chubu Electric, Kansai Electric Power Co, Shikoku Electric Power Co and Hokkaido Electric Power Co—to prepare to implement rolling blackouts for up to two hours a day, Fuji TV reported.
According to the ministry’s guidelines, the government will issue an alert in the morning if power demand looks like reaching 99% of capacity in areas serviced by the four utilities. An email alert will be sent to consumers 3-4 hours before the planned blackout, urging businesses and consumers to cut back on power usage. If power demand keeps rising, there will be a final alert two hours before the lights go off.
The ministry said the blackouts will last about two hours and only be implemented once a day for each area, Fuji reported.
Hospitals, prefectural government buildings, police and fire stations will be exempt, along with railways, airports and banking systems, the ministry said.
