Successful bidders are to supply electricity for 20 years while receiving subsidies for the initial construction and operating costs of the power plants. This enables long-term profit forecasting and supports the achievement of carbon neutrality by 2050. The three winning bids are located in Fukushima, Niigata, and Fukui prefectures with the Fukushima project having the highest capacity.
