South Fork Wind Holdings is the holding company for South Fork Wind, the first utility scale offshore wind farm built in United States federal waters. The project sits on the Outer Continental Shelf about 30 miles east of Montauk Point on Long Island and southeast of Block Island, and comprises 12 Siemens Gamesa turbines of 11 megawatts each for a nameplate capacity of 132 megawatts. An export cable brings the power ashore to an interconnection with the New York grid at East Hampton, and the Long Island Power Authority buys the output under a 20 year power purchase agreement approved in 2017. It was developed by Orsted with Eversource, began delivering power in December 2023 and reached full commercial operation in March 2024, supplying roughly 70,000 homes.

South Fork Wind Holdings, LLC (Class A tax equity interest) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Eversource Energy Form 8-K, 14 February 2024, Wikipedia: South Fork Wind, South Fork Wind, Bureau of Ocean Energy Management and Eversource Energy Form 8-K, 14 October 2025. The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- Eversource Energy, as of 31 Dec 2025. FY2025 10-K, Note 6: 'Tax Equity Investment in South Fork Wind 100% $19.1 [2025] $22.2 [2024]' (millions), inside the same 'Investments in Unconsolidated Affiliates' equity-method table as Algonquin. 10-K text: 'Eversource holds a noncontrolling tax equity investment in South Fork Wind through a 100 percent ownership in South Fork Wind Holdings, LLC Class A interests. In September 2023, Eversource made a $528 million investment in a tax equity interest for South Fork Wind... expected to result in cash flow benefits from ITCs at a 30 percent level.' The declining balance ($528m initial, $22.2m end-2024, $19.1m end-2025) reflects monetization of investment tax credits, not a sale of the interest. This is NOT the operating project stake (that was fully sold, see notes); it is a separate financing vehicle Eversource still owns outright. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of South Fork Wind Holdings, LLC (Class A tax equity interest) where a holder stated one, and are missing where no holder did.
