The power unit with a generating capacity of 1,000MW burns liquefied natural gas as feedstock.
TEPCO had shut this unit due to a fuel leak, after an earthquake hit the northeast coast of Japan’s main Honshu island on 11 March.
The damage caused by the 9.0-magnitude quake forced the company to shut down several nuclear and thermal power generating units with a total capacity of about 14,903MW.
The company is also trying to ease power shortages in Tokyo by restarting other generating units.
