Japan Wind Power Association (JWPA) announced Jan 17, 2018, that the total capacity of wind power plants introduced in 2017 (from January to December) in Japan was 169MW (77 plants).
The total capacity is 12% lower than the the total capacity of wind power plants introduced in 2016. The total capacity decreased two years in a row.
According to JWPA, the introduction of wind power plants has been discouraged by the fact that the revised environmental assessment was applied to wind power generation three months after the implementation of the feed-in tariff (FIT) policy (in July 2012) and the procedure for it takes four to five years and entails cost.
On the other hand, as of the end of December 2017, the number of wind power generation projects whose environmental assessment process is at the stage of "environmental impact statement" or later was 196. The total capacity of the projects is 16GW, 4.5GW of which is accounted for by offshore wind power plants.
"More introduction is becoming ready because the shortening of period started to show results thanks to the efforts of concerned government ministries," JWPA said.
Also, as of the end of December 2017, there were 3.399GW of wind power plants (2,225 plants). By prefecture, Aomori Prefecture came in first with 383MW, followed by Akita Prefecture (355MW) and Hokkaido (353MW). By the service area of general power transmission/distribution business, Tohoku-Electric Power Co Inc topped the ranking with 912MW, getting a big lead on Kyushu Electric Power Co Inc (500MW).
By manufacturer, Denmark-based Vestas Wind Systems A/S (including Denmark-based NEG Micon), General Electric Co (including Germany-based Tacke and France-based Alstom SA), Germany-based Enercon GmbH, Mitsubishi Heavy Industries Ltd and Hitachi Ltd (including Fuji Heavy Industries Ltd) accounted for 613MW, 569MW, 508MW, 404MW and 370MW, respectively.
