據OE網站7月9日報道，日本經濟新聞（Nikkei business daily）周四稱，日本將制定新規則，并支持基礎設施建設，旨在在未來10年在30個地點建設海上風力發電場。

該報道稱，預計日本產業大臣宮山弘治(Hiroshi Kajiyama)不久將宣布政策措施，以實現這一目標，但沒有確定消息來源。

新政策的目標是，從2021年4月開始的財政年度到2030/2031財政年度，每年建設3到4個總發電能力為1吉瓦的項目，累計總發電量為10吉瓦。

為了加快擴建，土地、基礎設施、運輸和旅游部計劃在全國范圍內為建造所需的部分建造儲存設施，并加固一些港口。

該報道補充稱，日本經濟，貿易和工業部（METI）計劃修改電網規則，以取消對綠色電力供應商的限制。

為了確保電網穩定，日本現在允許控制其輸電網的大型傳統公用事業公司在必要時限制可再生能源的供應，比如太陽能和風力發電廠，這一措施限制了可再生能源的擴張。

一位處理可再生能源的METI官員拒絕對此報告發表評論。一位MLIT官員表示，該部已經開始在一些港口開展工作，以使海上風電場受益，但拒絕對該報告其余部分發表評論。

每個工廠通常需要五到十年的時間才能建成。

去年，日本實施了一項名為《海上風力促進法》(offshore wind Promotion Act)的法案，以促進海上風力發電市場的發展。

Japan to Develop Offshore Wind Farms at 30 Sites in 10 years

Japan will craft new rules and support infrastructure in a drive that aims to build offshore wind farms at 30 sites during the next decade, the Nikkei business daily said on Thursday.

Industry Minister Hiroshi Kajiyama is expected to announce policy measures soon to target the goal, the paper said, without identifying sources.

The new policy aims for three or four projects each year with total generation capacity of 1 gigawatt (GW), from the financial year starting in April 2021 until fiscal 2030/2031, for an accumulated total of 10 GW.

To speed the expansion, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) plans to build storage facilities nationwide for the parts required for construction, as well as reinforce some ports.

The Ministry of Economy, Trade and Industry (METI) plans to revise power grid rules to scrap restrictions on greener power suppliers, the paper added.

Japan now allows large traditional utilities that control its transmission grids, to limit renewable energy supplies, such as those from solar and wind farms, if necessary, to ensure grid stability, a measure that limits renewable energy expansion.

A METI official handling renewable energy declined to comment on the report. A MLIT official said the ministry had already started work on some ports to benefit offshore wind farms, but declined comment on the rest of the report.

Each plant usually takes five to 10 years to build.

Japan's offshore wind power market is set to grow after a law, the Offshore Wind Promotion Act, enforced last year to assist development。
