Japan installed a new wind power capacity of 516 MW in 2020, most of which was onshore wind. The number of wind turbines increased by 116. The amount of new wind power capacity installed in 2020 was 1.9 times that of 2019, which is the largest amount of new wind power capacity installed in a single year ever. Cumulative wind power capacity at the end of 2020 reached 4,439 MW with 2,554 turbines, and the average size of newly built wind turbines increased to 2.7 MW.
The total amount of electricity generated by wind power in 2020 was about 7.64 TWh, which was 0.89% of the national electricity demand of 857.8 TWh.
Japan’s offshore wind capacity in 2020 was 67.6 MW. As part of NEDO’s Hibiki project, a barge-type floating wind turbine (3 MW) has been installed off the coast of Kitakyushu City and is undergoing demonstration operation.
