The 15MW of lithium-ion storage, on Long Island’s South Fork, would accompany the 90MW first phase of the 1GW Deepwater ONE project off the northeastern US.
The first phase — the Deepwater One South Fork project — would consist of 15 x 6MW turbines about 30 miles southeast of Montauk, New York.
The two batteries would be on Long Island, in Montauk and Wainscott, and online by 2018, according to Deepwater Wind.
Construction on Deepwater One South Fork could start in 2019, with commercial operation by 2022.
The US developer has proposed the innovative offshore wind-storage project in response to the utility PSEG-Long Island’s request for proposals for new electricity.
The USA’s first offshore project, the 30MW Block Island, is also being developed by Deepwater Wind and is using GE-Alstom 6MW Haliade turbines.
On December 2, New York’s Governor Andrew Cuomo issued an executive order stating that by 2030, half of all electricity consumed in New York must come from renewable sources.
In September, Deepwater Wind responded to New York City's Request for Information for new sources of renewable energy. "The waters off New York City are home to one of the country’s best offshore wind resources, and tapping [offshore wind] would do much to help New York City meet its 100-percent renewables goal – and to launch a new local industry," said Jeff Grybowski, CEO of Deepwater.
In 2011, Deepwater Wind's proposal to supply Long Island Power Authority (LIPA) with some power from its planned 900MW development, was rejected. In early 2014, Deepwater Wind again sought a contract from the LIPA for 200MW of power from Deepwater One project.
