Edgartown selectmen Monday postponed a decision on a routine request from Eversource Energy to install conduit and a new utility pole on Fuller street.

Selectmen are required by state law to hold a public hearing on requests to move or install poles.

At the board’s weekly meeting Monday, town manager Pam Dolby said recent poles replaced by Eversource were higher and larger in diameter than the poles replaced.

“The one that went on Upper Main street is much higher, another one went up on School street,” Mrs. Dolby said. “People asked about it when it happened. The last ones have been eight to 10 feet higher. It makes a huge impact.”

Eversource representative Jessical Edler said she would ask engineers if the larger pole is needed in that location.

“Standard poles are 35 feet,” Ms. Elder said. “The poles are bigger because they have to hold more.”

Selectmen continued the hearing until next week, when they expect more information from Eversource.

Also Monday, Vineyard Power Cooperative president Richard Andre briefed selectmen about progress on an offshore wind power facility south of Martha’s Vineyard.

Vineyard Power Cooperative formed a partnership with OffshoreMW, a New Jersey developer which successfully bid for a 160,000 acre tract in an auction organized by the U.S. Bureau of Ocean Energy.

Mr. Andre said that after Sept. 1, OffshoreMW plans to begin surveying the ocean bottom for exact depths, structures, and even shipwrecks. After that the company plans to conduct test borings.

“They’re going to bore up to 20 holes, about 240 feet below the sea bed,” Mr. Andre said. “Is it bedrock, cobble, sand? That’s all going to determine how the foundations of these towers go in.”

The developers will also be anchoring fixed buoys in the water to measure the strength of the wind.

Mr. Andre said the company is working closely with commercial fishermen and with the Wampanoag Tribe of Gay Head (Aquinnah), as well as other tribes in Massachusetts and Rhode Island.

Selectmen Art Smadbeck asked if Vineyard Power Cooperative members would benefit from less expensive electricity.

“I doubt that it’s going to be as cheap as they’ve estimated,” Mr. Smadbeck said. “It’s concerning that you’re working and putting so much time into something that’s not going to benefit the members.”

Mr. Andre said the cost of electricity from the wind farm is projected at 12 to 18 cents per kilowatt/hour. He said contracts would fix the price of the electricity over a time span of 20 years or more, with the cost more expensive in the short term, and less expensive in the long term, if conventional electricity generation prices rises.

He said his organization is also negotiating with the developer to locate a maintenance facility in Vineyard Haven Harbor that could provide about 30 jobs for people servicing and maintaining the wind turbines.
