The largest auction of offshore wind sites in the nation’s history is drawing strong interest from companies in an indication of the industry’s potential.

By Thursday afternoon, the second day of the auction by the U.S. Bureau of Ocean Energy Management, bids had exceeded $2.6 billion on six tracts of ocean floor off New York and New Jersey in an area known as the New York Bight.

When fully developed, these sites could provide enough energy to power 2 million homes, the agency said.

More than $1.5 billion worth of bids were received Wednesday, the first day of the auction, and officials said it is possible bidding could extend into a third day, given the strong response thus far.

The response to the auction “shows that the offshore wind industry has truly arrived,” said Doug O’Malley, director of Environment New Jersey, adding that it “proves that clean renewable energy off the Jersey Shore is poised to enter a boom period.”

The auction for nearly 500,000 acres (about 202,342 hectares), when combined with past auctions, will span nearly 1 million acres. It was the largest such auction in the nation’s history, BOEM said.

President Joe Biden has set a goal to install 30 gigawatts of offshore wind power by 2030, generating enough electricity to power more than 10 million homes.

The administration has approved the nation’s first two commercial-scale offshore wind projects in federal waters: the 800-megawatt Vineyard Wind project off the Massachusetts coast and the 130-megawatt South Fork wind farm near New York’s Long Island.

Not everyone is delighted with the scope and speed of offshore wind development. Homeowners groups in several spots in New Jersey are opposing the projects on environmental, economic and aesthetic grounds.

And even some environmental groups are displeased. New Jersey’s Clean Ocean Action called the auction “too much, too fast.”

“COA supports responsible and reasonable offshore wind energy, but this is a reckless privatization, and will not ensure protection of marine life including whales, dolphins, turtles and the hundreds of other species that call the ocean home,” the group said.

Cindy Zipf, the group’s executive director, said the auction area is five times the size of New York City.

Five of the six tracts are located off the central or southern coasts of New Jersey. The largest, at over 114,000 acres (about 46,134 hectares), is located off the coast of Long Beach Island, and could generate enough electricity to power nearly half a million homes, according to the ocean energy bureau.

The bureau said it will make public the identities of the successful bidders once the auction is concluded.
