In 2010, the US Energy Information Agency said "offshore wind power is the most expensive energy generating technology being considered for large scale deployment". [5] The 2010 state of offshore wind power presented economic challenges significantly greater than onshore systems, with prices in the range of 2.5-3.0 million Euro/MW. [36]
Offshore wind projects are under development in wind-rich areas of the East Coast, Great Lakes, and Pacific coast. The first offshore wind farm, Block Island Wind Farm, began operation in 2016. [2] The first commercial-scale (greater than 100 MW) offshore plant, the South Fork Wind Farm off Rhode Island, was fully commissioned on March 14, 2024.
There are three operating offshore wind farms in the United States, and several more are in permitting or under construction. The Bureau of Ocean Energy Management studies potential sites in federal waters for offshore wind energy development and leases sites to developers, who work with state regulatory agencies to interconnect and market their electricity.
The 2011 NREL report, Large-Scale Offshore Wind Power in the United States, analyzes the current state of the offshore wind energy industry. According to the report, offshore wind resource development would help the country to achieve 20% of its electric power from wind by 2030 and to revitalize the manufacturing sector.
Offshore Transmission Owners (OFTOs) operate and maintain offshore electric power transmission infrastructure in Great Britain, delivering electrical power from offshore wind farms to the National Grid. OFTOs may design and build this transmission infrastructure, but in most cases wind farm developers construct the electrical transmission ...
GE Offshore Wind is a joint venture with Alstom and a subsidiary of GE Vernova, created in 2015 when most of Alstom's electrical power and generation assets were acquired by General Electric. GE's stake in the joint venture is 50% plus 1 share.
The electric core is a concentric assembly of inner conductor, electric insulation, and protective layers (resembling the design of a coaxial cable). [5] Modern three-core cables (e.g. for the connection of offshore wind turbines ) often carry optical fibers for data transmission or temperature measurement, in addition to the electrical conductors.
Ocean Power Technologies (OPT) is a U.S. publicly owned renewable energy company, providing electric power and communications solutions, services and related for remote offshore applications. The company's PowerBuoy wave energy conversion technology is theoretically scalable to hundreds of megawatts and the generated energy from wave power can ...
