The operator of the main power plant in Hokkaido, northern Japan, has restarted one of the generators that were shut down after a powerful earthquake.
The quake on September 6th forced the Tomatoh-Atsuma thermal power plant to stop all 3 of the generators that were in operation. That triggered a massive blackout across one of Japan's main islands.
Last week, Hokkaido Electric Power Company restarted the No.1 generator, which has an output of 350,000 kilowatts.
The utility initially said the No.4 generator would not be restored until November at the earliest, because of a fire that occurred in its turbine.
But the No. 4 unit went back online early Tuesday morning after a test run and a safety check. It has the largest output of any of the generators at the plant, with 700,000 kilowatts.
With 2 of the 3 generators back online, Hokkaido Electric Power now can supply over 4.6 million kilowatts, which exceeds the prefecture's peak demand for power in October of last year.
The No.2 generator is not scheduled to be put back online until next month, due to newly found faults.
