据OE网站7月9日报道，日本经济新闻（Nikkei business daily）周四称，日本将制定新规则，并支持基础设施建设，旨在在未来10年在30个地点建设海上风力发电场。
该报道称，预计日本产业大臣宫山弘治(Hiroshi Kajiyama)不久将宣布政策措施，以实现这一目标，但没有确定消息来源。
新政策的目标是，从2021年4月开始的财政年度到2030/2031财政年度，每年建设3到4个总发电能力为1吉瓦的项目，累计总发电量为10吉瓦。
为了加快扩建，土地、基础设施、运输和旅游部计划在全国范围内为建造所需的部分建造储存设施，并加固一些港口。
该报道补充称，日本经济，贸易和工业部（METI）计划修改电网规则，以取消对绿色电力供应商的限制。
为了确保电网稳定，日本现在允许控制其输电网的大型传统公用事业公司在必要时限制可再生能源的供应，比如太阳能和风力发电厂，这一措施限制了可再生能源的扩张。
一位处理可再生能源的METI官员拒绝对此报告发表评论。一位MLIT官员表示，该部已经开始在一些港口开展工作，以使海上风电场受益，但拒绝对该报告其余部分发表评论。
每个工厂通常需要五到十年的时间才能建成。
去年，日本实施了一项名为《海上风力促进法》(offshore wind Promotion Act)的法案，以促进海上风力发电市场的发展。

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。
