Iberdrola is taking part in a new project to build a wind farm off the coast of Massachusetts (USA), in addition to Vineyard Wind 1. The farm is called Park City Wind, taking its name from the town of Bridgeport, which is known colloquially as The Park City.

With an investment of more than 1.338 billion euros, Park City Wind External link, opens in new window. will have an installed capacity of 804 MW, supplying approximately 14 % of Connecticut's electricity — equivalent to the energy used by 400,000 homes — and will prevent the emission of more than 25 million tons of carbon by the state.

The farm will be 37 kilometres off the coast of Massachusetts, south of Martha's Vineyard and Nantucket and right where there are the strongest winds on the east coast, although its silhouette will not be visible from anywhere on the coast of Connecticut.

Project benefits 

Park City Wind will completely change the area around Bridgeport, as an operations and maintenance centre will be installed there for the next 25 years.

It will create thousands of jobs and generate more than 890 million dollars (some 740 million euros) in investment and opportunities for economic development.

It will invest in technical training to ensure a long-term labour force, which can serve both Park City Wind and future offshore wind projects on the east coast.

It will invest in affordable housing.

A commitment has also been made to integrate existing businesses in Connecticut into the offshore wind power industry.

The project will be carried out through Vineyard Wind, a company in which AVANGRID* — Iberdrola's US subsidiary — holds a 50 % stake and the fund Copenhagen Infrastructure Partners (CIP).


The company has partnered with Marmon Utility LLC (Kerite) making it its preferred cable supplier for at least 50 % of the project and, which will make Kerite the first US Tier 1 Supplier in offshore wind.
