CIP pulls Vineyard 2 deal as US state shuns 'very expensive' offshore wind for solar

State declined to take 400MW of Danish developer’s costly array, prompting it to nix 800MW to Massachusetts

Connecticut’s choice of solar and storage over offshore wind has prompted Copenhagen Infrastructure Partners (CIP) to pull a deal for its 1.2GW Vineyard Wind 2 awarded by neighbouring US state Massachusetts.

The first 800MW was awarded by Massachusetts in the nation’s first tristate procurement in September on the condition that Connecticut take another 400MW to ensure it had the necessary scale.

Kathryn Niforos, spokesperson for CIP’s US subsidiary Vineyard Offshore, said: “We are grateful to Massachusetts for its provisional award of 800MW. With Connecticut’s decision today not to purchase the remaining 400MW we are unable to contract the project’s full 1,200MW at this time.

“We look forward to advancing this project and participating in future solicitations to meet the region’s growing energy needs,” she added.

Connecticut's Department of Energy and Environmental Protection (DEEP), the agency managing renewables procurement, opted instead for 518MW of solar and 200MW of battery storage.

In the tristate round, Massachusetts selected 2.6GW in three projects, which along with Vineyard 2 included Ocean Winds’ 1GW SouthCoast and Iberdrola-owned Avangrid’s 791MW New England Wind. Rhode Island added another 200MW to bring SouthCoast to 1.2GW.
Avangrid and CIP are partnered on US flagship array, the 800MW Vineyard Wind 1 currently under construction off Martha’s Vineyard, Massachusetts.

The loss of Vineyard 2 reduces Massachusetts' contracted capacity to 2.6GW towards its 5.6GW by 2027 mandate.

Massachusetts Department of Energy Resources told local media: “We will continue to explore all possibilities for moving this project forward and encourage Vineyard Offshore to participate in our anticipated 2025 solicitation.”

Cost concerns

As reported in local media the Connecticut Mirror, governor Ned Lamont said on a public radio podcast that offshore wind “seems very expensive”.

Massachusetts and Rhode Island have declined to reveal pricing in the latest round, but projects awarded in New York and New Jersey have come in between $135-145/MWh, levelised over their 20 or 25-year terms.

Connecticut DEEP likewise didn’t disclose prices for its newly awarded solar and storage projects but said they will come in “notably less” than other large scale solar arrays with offtake around 12-14 cents/kWh ($120-140/MWh).

Connecticut has 304MW of the total 704MW of Orsted’s Revolution Wind, shared with Rhode Island currently under construction that comes in around $99.5/MWh, according to industry group American Clean Power Association (ACP).

The solar capacity is in three projects, two of which will be located in Maine, highlighting the struggle to develop onshore renewables in the region’s small and densely populated southern states.
