About South Fork Wind

Powering Up South Fork Wind


New York welcomes America’s first commercial-scale wind farm 


In 1882, Thomas Edison lit up Manhattan with his power station on Pearl Street, kicking off New York’s history of energy firsts. Fast forward 140 years, and New York is once again entering a new era of clean power, completing America’s first commercial-scale offshore wind farm: South Fork Wind. 
 
South Fork Wind is a 12-turbine, 132 MW offshore wind farm powering ~70,000 Long Island homes. But the story of South Fork Wind goes beyond turbines, megawatts, and homes powered. It’s a story of union workers, engineers, and conservationists. A story of industry, investment, and laying the foundations for America’s offshore wind infrastructure. 

Above all, it’s a New York story – a project by New Yorkers, for New Yorkers.

Completed in 2024

First approved by the Long Island Power Authority in 2017, construction of South Fork Wind started in January 2022 and ended in March 2024.

Together, the 12 turbines that make up South Fork Wind will generate 132 MW of clean energy.

Frequently asked questions (FAQ)
  • How will the energy from South Fork Wind reach the grid?

    Offshore wind farms are connected to the electrical grid using submarine transmission cables that are attached to offshore wind turbines. Energy passes through the cables to an offshore substation, and is then transported to shore via subsea cables. These cables run deep beneath the beach, remaining buried along the entire length of the coastal zone, avoiding impacts on sensitive habitats.

    From there, the buried cable runs along existing roadways and rights of ways, alongside other utility infrastructure, to an inland substation in East Hampton, where energy is delivered to the electrical grid.

  • How does offshore wind’s environmental footprint compare to other energy sources?

    Depending on its size, the lifecycle emissions of an offshore wind turbine max out around 15 grams of carbon CO2 equivalent (i.e., carbon emissions compared to fossil fuel sources) per kilowatt-hour. The majority of these emissions occur during the production and construction phases of development.

    This is no more than 3.5% of the lifetime emissions produced by common fossil fuels. Power plants burning natural gas can emit between 430 and 760 grams of CO2e per kilowatt-hour. Coal-fired plants fare even worse, producing up to 1,700 grams of CO2e per kilowatt-hour.

    While Ørsted is working to reduce the carbon intensity of wind turbine production, lifecycle assessments show offshore wind to be the cleaner alternative.


  • What happens when South Fork Wind reaches the end of its lifecycle?
    When South Fork Wind reaches the end of its lifecycle, the turbines will be decommissioned and removed from the ocean. The materials making up the turbines will then be recycled.
  • What are electromagnetic fields? How do they interact with offshore wind farms?
    Electromagnetic fields (EMF) are a combination of electric and magnetic fields of force. EMF are generated wherever electricity is transmitted or used (e.g., by household appliances, electric wiring, power lines).

    EMF are typically localized. In the case of offshore wind farms, offshore and onshore cable systems are often the source of EMF. They are strongest closest to the point at which the fields originate and decrease rapidly in strength the farther they are from the source.

    We perform a modeling analysis on our cables to ensure that any EMF emissions are below required thresholds.

Powering up the people and industries of New York

New York takes first place in offshore wind


With South Fork Wind, the Empire State is piling up national offshore wind firsts. The project features the country’s first American-built offshore substation, and is the first offshore wind farm to use an American-made and -crewed service operations vessel. To provide long-term support to South Fork Wind, New York is opening its first Operations & Maintenance center in East Setauket and a first offshore wind training center in Brentwood
 
These clean energy firsts add up to more than just a single offshore wind farm. They’re paving the way to a renewably powered New York, one that can meet its clean energy goals while bringing jobs, training, and more resilient infrastructure to New Yorkers. 

The first American-made service operations vessel, the Eco Edison, will support the operations and maintenance of our offshore wind projects in the Northeast 

Boosting industry, locally and nationally


South Fork Wind has put New York’s offshore wind industry on the map, creating new business for local companies. Long Island’s Haugland Energy Group and Elecnor Hawkeye installed the project’s underground duct bank and onshore substation, and its onshore cables, respectively. Concrete mattresses were manufactured by Roman Stone, another Long Island company, and upstate manufacturer Ljungström fabricated steel parts for the project’s foundations.  
 
And the business benefits of South Fork Wind – greater manufacturing, investment, and infrastructure – extend well beyond the Empire State. The project’s offshore substation was built in Texas, its export cable in South Carolina, and its foundation components in Rhode Island, while assembly happened in Connecticut. That’s nearly 1,000 jobs across 5 states supporting the build out of America’s offshore wind industry. 

All 36 turbine blades used for South Fork Wind were marshalled at the New London State Pier in Connecticut

Every trade in the community was involved. Linemen, electricians, laborers, operating engineers, tradesmen, everyone played a part in building South Fork Wind. It's a great accomplishment for Ørsted, Eversource, the Haugland Group, for every company that participated.
