Those of you who have seen the movie Jaws know that the scariest and most powerful creatures can be found in the sea. However, somewhere off the coast, you can find something that is very powerful, but not at all scary, namely 800 MW. That is a lot of power, and guess what, it’s all floating in one of the American seas. This floating power is useful in more ways than you can know.

An 800 MW offshore project to power the nation

In the race to utilize clean and sustainable energy, Massachusetts has taken the lead. It was the country’s first state to sign off on a large-scale wind project, and invested in a 2050 Clean Energy and Climate Plan as part of its commitment to supplying green, cost-effective, and sustainable power to ratepayers.

On February 22, 2024, Governor Maura Healey and Lt. Governor Kim Driscoll made an important announcement. For the first time, a massive and powerful offshore project’s first phase had supplied electricity to the New England power grid. The power is transmitted with submarine cables via a route from an offshore substation to an onshore substation in Hyannis village. These cables are buried up to six feet deep.

This massive and powerful offshore project is the ‘Vineyard Wind 1’ project, which is the first extensive offshore wind project in Massachusetts. A partnership between Avangrid, Inc. and Copenhagen Infrastructure Partners (CIP), through its affiliate Vineyard Offshore, is responsible for Vineyard Wind 1. The Northeast region relies on offshore wind as an energy resource. The region’s location is ideal to exploit offshore wind energy to meet the high energy demands of New England, especially during its winter peak.

This is where you can find the offshore project floating about

We’ve mentioned the movie Jaws for this very reason. Around 15 miles south of the island, Martha’s Vineyard, and 35 miles from Massachusetts’ mainland, is the wind energy location OCS-A-0501. OCS-A-0501 is exactly where Vineyard Wind 1 is floating about. According to Vineyard Wind, it is the ideal spot for wind turbines due to powerful and reliable wind speeds.

Phase 1 of the project consisted of five turbines, which alone produced a power capacity of 68 MW. That can reportedly power 30,000 households in Massachusetts. The turbines are General Electric Haliade-X turbines and are separated by 1 nautical mile. Once Vineyard Wind 1 is completed, 62 turbines will be fully operational in the spot. The entire project is planned to have a power capacity of a whopping 800 MW to power 400,000 households.

Offshore wind projects are becoming increasingly popular for their high power output, but they include other advantages that should not be overlooked.

The project is about more than just power

Yes, this massive offshore wind project has the potential to supply a lot of power to many households and businesses, but let’s not forget the other advantages of large-scale projects like Vineyard Wind 1.

Additional advantages of Vineyard Wind 1

  • Decreased carbon emissions of over 1.6 million metric tons annually (which is comparable to removing 325,000 vehicles off the road each year)
  • Since 2017, almost 2,000 high-quality, skilled jobs have been created
  • Since 2017, it has created nearly 1,000 union jobs (a subset of the above)
  • It will create 3,600 full-time equivalent job years
  • In the first 20 operational years, customers will save $1.4 billion

“This marks a turning point in the clean energy transition. After many decades of advocacy, research, policymaking, and finally construction, America’s offshore wind industry has gone from a dream to reality.” – Governor Maura Healey

With great power comes great responsibility. The Vineyard Wind 1 project is a good example of how large-scale renewable energy projects can benefit local communities in more ways than one. Proper management and strict environmental guidelines are key.
