PROJECT

South Fork Wind

We were the program manager for the onshore components of Ørsted’s South Fork Wind project, the first utility-scale offshore wind farm in the U.S., sited 35 miles from Montauk Point. The 12-turbine, 132-megawatt facility can generate enough energy to power 70,000 Long Island homes through a power purchase agreement (PPA) with the Long Island Power Authority (LIPA). It was fully commissioned in 2024.

Working with Eversource Energy, our team oversaw the permitting, engineering, procurement and construction of about 4 miles of 138-kV export cable and a greenfield 138-kV/69-kV onshore collector substation. As part of project development, we performed early-stage conceptual design in support of various regulatory proceedings. Our services then transitioned to be more multidisciplinary, providing project management, construction management, stakeholder engagement, safety oversight and project control services from preconstruction through commissioning.

Construction began with installation of the duct bank along town roads in parallel with site/civil work at the substation. Due to time-of-year construction conditions, construction along town roads during the summer months was paused; during those months the team focused on construction of the 138-kV export cable system along the Long Island Rail Road corridor as well as the new substation. The substation included equipment unique to offshore wind projects such as a static synchronous compensator (STATCOM) and a harmonic filter.

To facilitate the landfall of the offshore cable, a 2,500-foot offshore-to-onshore horizontal directional drill was performed with offshore jack-up barges and other marine equipment within New York State waters. We worked with Ørsted to coordinate the onshore and offshore design interface. We also deployed a field team to manage external stakeholder queries, oversee local authority interfaces, and manage overall construction and safety at the landfall site. 

The project began producing power in late 2023, with the onshore scope completed safely and on time without a lost time incident. Initially a joint venture of Eversource and Ørsted, the project is now owned by Ørsted and Global Infrastructure Partners (GIP).
