Tokyo Electric Power Co Holdings, Inc (Tepco) will start output from the No. 7 unit at the Kashiwazaki Kariwa facility in October, under a base-case scenario, BNEF analysts including Mariko O’Neil and Yumi Kim said in the research group’s inaugural report on Japan’s power market, published on Monday. It will be the first time Tepco will operate a nuclear reactor under safety rules implemented after the meltdowns at its Fukushima Dai-Ichi facility in 2011, which led Japan to halt all of its atomic generation.
