据海事新闻网8月27日消息称，美国海上风电项目开发管道的潜在发电能力达到25824兆瓦，横跨13个州，其中包括2016年投产的布洛克岛风电场。

总计21225兆瓦的项目具有独家站点控制权，这意味着开发商拥有开发站点的租约或其他合同。美国能源部国家可再生能源实验室编写的海上风电技术市场报告称，这些项目大多位于东海岸，其中一个位于五大湖区。

它说，加利福尼亚州和夏威夷州有几个早期的海上风力发电项目正在规划阶段。

美国内政部海洋能源管理局(BOEM)对马萨诸塞州近海三个租赁区域的拍卖成交价为1.35亿美元，是此前BOEM拍卖成交价的三倍多，显示出市场对美国近海风能市场的浓厚兴趣和信心。

美国首个商业规模的海上风力发电项目——马萨诸塞州海岸葡萄园岛风力发电项目——销售价低于预期，为每兆瓦时65美元至75美元。

大型涡轮机的技术趋势仍在继续，2018年全球海上涡轮机的平均装机容量为5.5兆瓦，未来几年将有10至12兆瓦的涡轮机投入市场。

US Offshore Wind Pipeline Reach 25.8GW

The U.S. offshore wind project development pipeline grew to a potential generating capacity of 25,824 MW across 13 states, including the Block Island Wind Farm commissioned in 2016.

Projects totaling 21,225 MW have exclusive site control, meaning the developer has a lease or other contract to develop the site. Most of these projects are on the Eastern seaboard, with one in the Great Lakes, said Offshore Wind Technologies Market Report, prepared by DOE’s National Renewable Energy Laboratory.

California and Hawaii have several early-stage floating offshore wind projects in the planning phase, it said.

The Department of the Interior’s Bureau of Ocean Energy Management (BOEM) auctions for three lease areas off the coast of Massachusetts brought in winning bids of $135 million—more than three times the value of previous BOEM auctions—indicating strong interest and confidence in the U.S. offshore wind market.

Offtake prices for the first commercial-scale U.S. offshore wind project—Vineyard Wind off the coast of Massachusetts—came in lower than expected at $65–$75 per megawatt-hour.

Technology trends toward larger turbines continued, with offshore turbines installed globally in 2018 averaging 5.5 MW, and turbines with capacities of 10-–12 MW coming to market in the next couple years.
