The Ministry of Economy, Trade and Industry has raised its estimate for the cost of generating nuclear power to around ¥10 per kilowatt-hour, up by about ¥1, informed sources said Friday.
The previous estimate was “at least ¥8.9,” the sources said.
The revision was made after nuclear power plant operators allocated huge amounts of money to meet new safety standards set by the nation’s new atomic regulator, the Nuclear Regulation Authority, in July last year, they said.
Despite the cost increase, however, nuclear power is still cheaper than thermal power, they noted.
The ministry plans to present the new figure at a meeting of experts to be held Monday to discuss souce-by-source electricity generation costs for determining a best energy mix for Japan.
