If you’ve been to Smith Point County Park recently, you may have noticed some large equipment there.

Contractors for Orsted, the company that is developing a 924-megawatt wind farm off the coast at Montauk, are preparing for horizontal directional drilling under the beach. Cables from 84 offshore wind turbines, at least 30 miles off the Montauk coast, will come ashore under the beach at Smith Point. From there, they will travel underground to a converter station in Holbrook and continue to a PSEG substation in Holbrook.

The work currently underway at Smith Point “will prepare for eventual landfall of the project’s submarine export cable and is expected to continue until the end of March,” a Sunrise Wind spokesperson said in an email.

Four hundred New York union workers are on Long Island building the project, the spokeswoman said.

Access to the beach and marina at Smith Point will be maintained, she said.

Sunrise Wind is expected to be operational in 2026. It will produce enough electricity to power almost 600,000 homes and generate $700 million in economic benefits for the region, including a regional operations and maintenance center to be built in Port Jefferson, Sunrise Wind’s website said.

The Town of Brookhaven will receive almost $170 million over 25 years for hosting Sunrise Wind, including $5 million for construction of Tri-Hamlet Park and other community projects.
