Nuclear Seen as Cheapest Energy Source for Japan, Ministry Says

(Bloomberg) — Nuclear power generation in Japan will cost
10.3 yen per kilowatt hour or more by 2030, the cheapest among
various power sources, according to a government report.

Offshore wind is estimated to be the most expensive among
clean energy sources, costing 30.3 yen to 34.7 yen by 2030. That
compares with 13.6 yen to 21.5 yen for onshore wind, the
Ministry of Economy, Trade and Industry said in a report
compiling estimates on power generation costs for 2030.

Large-scale solar will cost 12.7 yen to 15.6 yen, while
residential solar will cost 12.5 yen to 16.4 yen, according to
the ministry.

The report was presented to a ministry task force Monday
after adjustments were made since a meeting last month amid a
nationwide debate on energy use and climate change.

The trade ministry also gave estimates on geothermal and
coal power at 16.8 yen and 12.9 yen, respectively. Liquefied
natural gas power will cost 13.4 yen.
