In 2017, Japan’s total installed wind power capacity reached 3,399 MW, including 64.6 MW of offshore capacity. The annual net capacity increase was 169 MW. Total wind-generated electricity during 2017 was about 5.8 TWh, which corresponded to 0.64% of the national electricity demand (906.2 TWh).

Although the environmental impact assessment (EIA) review process has been streamlined, new wind farm projects (with an additional capacity of 16 GW) are still undergoing the EIA review process. Some projects are proceeding in port and ocean areas, where Japan has considerable potential for offshore wind farms

National Targets

Following publication of The Fourth Strategic Energy Plan, the Ministry of Economy, Trade and Industry (METI) issued the Long-Term Energy Supply and Demand Outlook, which included an estimate for the power source mix in 2030. The projected share of wind energy in Japan’s 2030 power source mix is 1.7%, or 10 GW of capacity, including 0.82 GW of offshore wind power. However, according to a Japan Wind Power Association (JWPA) report, wind energy capacity will probably exceed this share by the early 2020s.

Progress & Operational Details

Japan installed 169 MW of new wind power capacity in 2017. Cumulative wind power capacity reached 3,399 MW across 2,225 turbines at the end of the year. Electrical energy output from wind-based sources during 2017 totaled approximately 5.8 TWh—0.64% of the national electricity demand. Japan’s operational offshore wind power capacity reached 64.6 MW in 2017. The Fukushima FORWARD project started operation in March 2017 with one 5-MW wind turbine built on an advanced spar-type floater (manufactured by Japan Marine United Corporation).

National RDD Priorities and Budget

METI and the New Energy and Industrial Technology Development Organization (NEDO) administer the main national R&D programs in Japan. Many of these programs focus on lowering the LCOE of offshore wind. NEDO Research and Development of Offshore Wind Power Generation Technologies (FY 2008-2022) has worked on the following:

Research on Next-Generation Floating Offshore Wind Power Generation System
Offshore Wind Resource Map
Low Cost Construction
