Now the developer of the wind farm may turn to an alternate landing site, bringing the cable ashore in Hither Hills in Montauk, a popular state park, and then burying it for nearly 12 miles before connecting it to a substation. Landing the cable in Wainscott would require a journey of about four miles.

In Montauk, resentment is building among some residents over the idea that they may be forced to accept the cable landing because of a campaign mounted by the deep-pocketed in Wainscott.

“That’s always the irony in these things: ‘It’s a great idea and we want it, but don’t do it here,’’’ said Paul Monte, the president of the Montauk Chamber of Commerce. “If it disrupts things for the lesser folks that’s O.K., but just don’t do it to our road.”

Montauk, of course, has plenty of its own millionaires, and residents there have started organizing to oppose the Hither Hills site.

“I just hope cooler heads will prevail,’’ Mr. Monte said, “and they will choose the location that makes the best sense and not base it on who has hired the more powerful lawyers.”

State regulators will ultimately choose the landing site, but the Wainscott site would also need the approval from two local town panels. The Montauk site, because it is a state park, would not require any local approval.

With 15 turbines to be placed in waters 35 miles east of Montauk Point, the project — a joint venture between Danish and Connecticut companies — aims to ease an annual summer energy shortage in East Hampton and Southampton, while helping the towns reach their goal of 100 percent renewable energy.
