RWE-backed SATH technology scores a floating wind first for Spain | Recharge
A joint venture between Spain’s Saitec Offshore Technologies, German energy giant RWE and Japan’s Kansai Electric Power has started generating electricity from a 2MW pilot of a new floating wind platform in Spanish waters.
The floating offshore wind platform, dubbed DemoSATH, is moored at the 85m deep BiMEP test site, located two miles offshore and about 11 miles from the port of Bilbao, in the Cantabrian Sea.
Saitec Offshore's SATH technology is based on a concrete platform concept with a plug-and-play single-point mooring that can facilitate disconnection for operations and maintenance work.

Over the next decade, U.S. offshore wind power is expected to grow from a single 30-megawatt wind farm off Rhode Island to more than 2,000 MW of capacity along the Atlantic Seaboard. There are contracts for wind power off the coasts of Massachusetts, Connecticut, New York, Maryland, New Jersey, Rhode Island, and Virginia.
The National Renewable Energy Laboratory has estimated the United States has over 4,000 gigawatts (GW) of offshore wind potential, enough to power the country four times over.
The growth in part being spurred by state solicitations, including in New York, where then-Gov. Andrew Cuomo (D) set a commitment of 9,000 MW of offshore wind by 2035, and in Connecticut, where in June 2021, Gov. Ned Lamont (D) signed legislation authorizing the construction of 2,000 MW of offshore wind by 2030.
The offshore development is also being driven by an investment tax credit set to end in December 2019 and is equal to 12 percent of expenditures. U.S. Sens. Susan Collins (R-Maine) and Tom Carper (D-Del.) have introduced a bill to extend the tax credit for up to eight years.
The Interior Department has held eight competitive lease sales that resulted in 15 offshore wind leases over 1.7 million acres that has the potential for 21 GW of capacity. In February 2022, the Bureau of Ocean Energy Management completed a bidding process that realized $4.37 billion for 488,000 acres across six lease areas in federal waters off New York and New Jersey.
Projects have also been proposed off the Southeast coast, off California and Hawaii, and for the Great Lakes.
