Tohoku Electric Power Co. has started talks to seek compensation from Tokyo Electric Power Co., manager of the crippled Fukushima No. 1 plant, over losses from dropping electricity sales in Fukushima Prefecture, sources said Wednesday.

Tohoku Electric saw the amount of electricity sold in Fukushima drop by up to nearly 30 percent in a single month after the March 2011 disasters triggered the nuclear crisis that forced residents from their homes. The amount sold has yet to recover.

The move comes as the utility grapples with seriously deteriorating business conditions from the quake and tsunami. The disasters damaged its power generation facilities and caused its nuclear reactors to be suspended.
