Wind power in Japan

In Japan's electricity sector wind power generates a small proportion of the country's electricity. As of 2019, the country had a total installed capacity of 3,923 MW. Government targets for wind power deployment are relatively low when compared to other countries, at 1.7% of electricity production by 2030.[1] It has been estimated that Japan has the potential for 144 GW for onshore wind and 608 GW of offshore wind capacity.[2]

The Shin Izumo Wind Farm owned by Eurus Energy was the largest wind farm in Japan as of 2011, comprising 26 turbines with a total nameplate capacity of 78 megawatts.[6]

The Shin Aoyama Wind Farm owned by C-tech is currently the largest wind farm in Japan, as of February 2018. It comprises 40 turbines with a total nameplate capacity of 80 megawatts. The amount of electrical power that can be generated is equivalent to the annual consumption of about 44,000 ordinary households.[7]

The Yurihonjo Offshore Wind Farm located in Akita Prefecture is expected to begin construction in 2021. It will comprise 70-90 turbines with a proposed capacity of as much as 1000 megawatts. Upon completion, its capacity is projected to be the largest offshore wind farm in Japan.[8]

In 2011, Japan stated plans to build a pilot floating wind farm, with six 2-megawatt turbines, off the Fukushima coast.[9] After the evaluation phase is complete in 2016, "Japan plans to build as many as 80 floating wind turbines off Fukushima by 2020."[9]

In 2013, a floating offshore wind turbine was tested about 1 km off the coast of the island of Kabajima in Nagasaki Prefecture. It was a part of a Japanese government test project.[10] This was the first of its kind in Japan.
