JERA, Japan's biggest power generator, has started preparation work to restart another aged power generation unit at its Anegasaki thermal power station in Chiba Prefecture, to help the region avoid any power crunch during the peak winter demand season.
Japan's energy supply problems relate to various domestic issues, including the suspension of some plants after March earthquakes in Fukushima, a drop in the number of thermal plants and delays to the restart of nuclear plants because of tighter regulation following the Fukushima disaster in 2011.
JERA is already set to restart the 45-year-old 600-megawatt No.5 gas-fired unit in Anegasaki between July 1 and Aug. 31, as it has won an auction to provide extra electricity during the summer to make up for any shortfall.
