The first two reactors to be restarted since the Fukushima nuclear crisis brought all 50 to a halt earlier this year made atomic power account for 2.9 percent of all electricity generated in July, the first rise in eight months, the Federation of Electric Power Companies of Japan said Monday.
Kansai Electric Power Co. restarted units 3 and 4 at its Oi plant in Fukui Prefecture in July after the last active nuclear power plant was shut down for routine maintenance on May 5, but the July figure is still down 31.0 points from last year and is unlikely to rise quickly.
The federation said that combined output and electricity purchases by the 10 power utilities in July fell 1.4 percent from a year before to 81.78 billion kwh, down for the second consecutive month.
The industry group attributed the drop chiefly to less use of air conditioners amid lower temperatures than last year. Nationwide efforts to save electricity also had an impact, it said.
Of the month’s overall power output, 1 billion kwh were produced by nuclear power, down 91.9 percent, and 55.95 billion kwh by thermal power generation, up 13.2 percent.
