BOSTON — Massachusetts Attorney General Andrea Joy Campbell told the Trump administration Thursday that she is going to sue over the federal cancellation of two offshore wind farms that would have supplied electricity to New England, teaming up with seven other Democratic attorneys general to file formal notice of the coming lawsuit.

Bluepoint had been awarded a $765 million lease off the coast of New York more than four years ago. In April 2026, Interior announced a settlement in which Bluepoint would cancel its lease in exchange for hundreds of millions of dollars in taxpayer money. The settlement also required Bluepoint to invest those funds in oil and gas projects — and to walk away from offshore wind development in the United States entirely.

In June 2026, Interior announced a nearly identical settlement with Invenergy, which had previously been awarded offshore-wind leases totaling more than $653 million off the coasts of New York and Maine.

Together, the two cancelled projects would have supplied electricity to about 3 million homes in New York, New Jersey and New England, according to Campbell's office.

The Interior Department justified the cancellations by citing "new national security concerns." Campbell's coalition argues in the notices that the federal government had already reviewed and approved the same lease areas after years of analysis and consultation with the Department of Defense.

The coalition contends the settlements violate the Outer Continental Shelf Lands Act, which limits Interior's ability to cancel offshore-wind leases. Under the statute, Interior must hold a hearing and make specific findings that continuing a lease would likely cause serious harm to life, property, national security or the environment — and then determine that the benefits of cancellation outweigh the benefits of allowing the lease to continue. Campbell's office says Interior did none of that before cancelling the Bluepoint and Invenergy leases.

Joining Campbell in filing the notices were the attorneys general of Connecticut, Delaware, Maine, New Jersey, New York, Rhode Island and Vermont. Under the 60-day OCSLA notice window, the earliest the coalition can file its lawsuit is mid-September.

The notices come one month after Campbell filed a separate lawsuit against Interior over the Trump administration's earlier settlement with TotalEnergies, which resulted in the cancellation of another major offshore-wind project off the coast of New York. Between the TotalEnergies suit and Thursday's notices, Campbell has now teed up three federal wind-project lawsuits against the administration in two months.
