VINEYARD WIND 1 OFFSHORE WIND FARM
Vineyard Wind 1, our first offshore wind farm in the United States
Iberdrola, through Avangrid Renewables, will take part in the development of a large-scale offshore wind farm off the coast of the state of Massachusetts, United States. Vineyard Wind 1 will have a capacity of 800 MW, which will be able to meet the energy needs of one million homes.

offshore wind farm
Vineyard Wind, a company in which Iberdrola has a 50% stake — through Avangrid Renewables, an Avangrid* Nota subsidiary — and by Copenhagen Infrastructure Partners (CIP), has been awarded a contract to develop an 800 MW offshore wind farm opposite the coast of Massachusetts. This is Vineyard Wind 1, where building will commence in 2019 15 miles south of Martha's Vineyard 34 miles south of the Cape Cod peninsula.
The complex, which is expected to go into service in 2023, will generate approximately 2 gigawatts of wind power, sufficient to meet demand from 1 million homes in Massachusetts. It will also prevent the emission of more than 1.6 million tons of carbon dioxide every year, the equivalent to withdrawing 325,000 vehicles from the roads. In addition, during the life of the project, a total of 3,700 million dollars will be saved in energy costs in the region of New England.
This new development will be Iberdrola's group's first offshore wind project in the United States, ratifying its position as a global leader in this area. Avangrid Renewables also has the rights to develop another offshore wind farm project in the Kitty Hawk area off the coast of North Carolina, with a capacity of up to 1,486 MW.
Vineyard Wind is still processing the permits to start building and commissioning Vineyard Wind 1. The Final Environmental Impact Report has already been approved and the company has signed long-term energy sale agreements, which are known as Power Purchase Agreements (PPAs) with Massachusetts electricity retailers. Currently, 70% of these PPAs are assured.
MHI Vestas Offshore Wind has been selected as the preferred supplier of the 84 wind turbines that will power the new wind farm. The chosen model is the MHI V164, which, with 9.5 MW of power, is the most powerful in the world, and was named the Best Offshore Wind Turbine of 2017 by specialist journal Windpower Monthly. MHI Vestas is planning to hire 100 workers and invest more than 15 million dollars in the Massachusetts economy during the construction phase.
In the meantime, Windar Renovables will be responsible for manufacturing the wind turbine foundations. The contract is worth around 100 million euros and will create approximately 400 jobs (500 at peak times) at the plant in Asturias (Spain).
Finally, Vineyard Wind has entered into an agreement with Italian company Prysmian Group worth 200 million euros to design, manufacture, install and commission the submarine cabling system that will connect the offshore wind farm with the Continental US power transmission grid. The project will require a total of 134 kilometres of high voltage alternating current electric cable.
Vineyard Wind has presented Massachusetts electricity retail companies with a set of proposals to develop a second offshore wind farm, Vineyard Wind 2, which will be installed to the south of the former. The proposals include a 400 MW project and options to develop a further 800 MW.
Besides, another project — this in the state of Connecticut — was chosen to advance to contract negotiations by the Connecticut Department of Energy and Environmental Protection (DEEP). With its 804 MW, the offshore wind development of Park City Wind will power approximately 14 percent of Connecticut's electricity supply and avoid emitting more than 25 million tons of carbon emissions in the state. Its silhouette will not be visible from any point on the coast of Connecticut.
In this same state, the company intends to partner with two local companies, McAllister Towing and Bridgeport Boatworks, to develop an offshore wind farm in Bridgeport. If approved, this initiative will create over 500 jobs in Connecticut during the construction phase and 1,900 during the entire project. It will also bring in over 4 billion dollars in revenue to the state, improve the reliability of the electricity supply and stabilise prices.
