Connecticut is seeking to procure up to 2GW of offshore wind capacity in the latest round of power deals in the US offshore wind sector.

Under the terms of the solicitation, each developer must provide one 400MW project proposal, as well as plans to mitigate impact on fishing and the environment.


Vineyard Wind – a JV between Iberdrola subsidiary Avangrid Renewables and Copenhagen Infrastructure Partners – proposed the "Park City Wind" project with 408MW, 800MW, 1GW or 1.2GW options.

The developer said the project would be installed in the federally designated lease areas it was awarded off Massachusetts.

"Both lease areas are located south of Martha’s Vineyard and Nantucket in the midst of the strongest winds on the east coast and would not be visible from any shoreline in Connecticut," Vineyard said in a statement.


The partnership between EDPR Offshore North America and Shell New Energy put forward 408MW and 804MW options.

The project is also set to be installed in the federal lease areas south of Martha’s Vineyard.

The developers said they would provide enhanced electrical reliability to the state by offsetting the closures of the Brayton Point and Pilgrim nuclear power stations, and reducing the reliance on natural gas.


The Ørsted and Eversource JV proposal is located 105km off New London, Connecticut. The project partners said it has already collected two years of floating lidar data at the site.

The project was initially planned to be 200MW but must have been extended to at least 400MW to match the solicitation requirements.

"Through our four years of project development and outreach, we have heard the enthusiasm for offshore wind from residents, businesses, and communities across the state," said Eversource executive vice president Lee Olivier.
