Akihabara News (Tokyo) — With several new projects under construction and renewal of old turbines, Electric Power Development (J-Power) expects to have 650 megawatts of wind energy in service by FY2024.
At present, J-Power has about 540 megawatts of wind energy operating at 23 locations around Japan. This is equivalent to more than half of the electricity generation capacity of a conventional nuclear reactor.
The wind farms tend to be rather small, with the average number of turbines at a single site averaging about twelve. Geographically, they are widely spread from Kagoshima to Hokkaido.
J-Power has two new wind farms under construction, a 42 megawatt site in Hokkaido and a 34 megawatt site in Ehime, each of which will feature ten turbines.
Moreover, there are two sites in Hokkaido with a combined generation capacity of 35 megawatts that are currently offline for renewal.
In its latest announcement, J-Power has revealed that its oldest wind farm, the twenty-year-old Nikaho Kogen Wind Farm in Akita, is also entering a renewal process. In its case, its fifteen existing aged wind turbines, which each have a capacity of 1.6 megawatts, will be replaced with six new 4.3 megawatt wind turbines supplied by Siemens Gamesa.
