In 2021, Japan installed a new wind power capacity of 211 MW, most of which was the onshore wind. Cumulative wind power capacity at the end of 2021 reached 4,581 MW with 2,574 turbines. Of this, offshore wind power generation capacity was 51.6 MW.
The national capacity factor (average national capacity factor) was 21.5%. The total amount of electricity generated by wind power generation in 2021 was about 8.47 TWh, which was 0.97% of the national electricity demand of 873.2 TWh.
Notably, the number of decommissioned wind turbines, with a capacity of 68.2 MW, increased remarkably in CY2021, compared to the previous year. This suggests that the number of wind turbines that are due for renewal is increasing.
