Adjusted gross proceeds from the transaction were $745 million for the two projects combined. Eversource exited its ownership but retained a tax-equity investment in South Fork Wind.

Both appear valid and reflect different nameplate conventions. The registry entry uses the EIA anchor value of 130 MW, and the equipment/owner configuration (12 × 11 MW turbines = 132 MW) is documented separately. Ownership transition: The asset transitioned from joint Ørsted/Eversource ownership (50/50) to joint Ørsted/Global Infrastructure Partners ownership (50/50) on September 30, 2024. Both ownership structures and the transition date are documented. Eversource remains a tax-equity investor after the sale. No plant-specific price or financing details are publicly available. Construction cost estimate: The renewablesinfo.org plant record identifies an estimated construction cost of approximately $274.8 million based on EIA-average technology costs, explicitly noting that this is not a plant-specific financial report. Historical ownership: Ørsted acquired Deepwater Wind's assets in November 2018, including the predecessor South Fork Wind project. The exact ownership chain from initial development to current joint venture is documented in the events and entity sections. --- Canonical page: https://askthegrid.com/nyiso/assets/plant/south-fork-wind Source: Ask the Grid — https://askthegrid.com/
