Eversource Energy’s plans to spray herbicides under power lines on the Vineyard remained in the spotlight this week.

The Martha’s Vineyard Commission, state representatives, town officials and others are all calling on the utility giant to find alternatives to herbicide spraying under power lines this year.

For the first time in four years, Eversource Energy plans to apply herbicides under some of its power lines on the Vineyard. A public comment period ends March 27.

The future of the Cape Wind project on Horseshoe Shoal was thrown into uncertainty this week when National Grid and NStar announced they had terminated their contracts to buy power from the private wind developer.

Islanders can expect to see their electric bills go up this winter, with Cape Light Compact and NStar both announcing increases in electricity costs beginning as early as December. Utility companies said the price increase can be attributed to a growing demand for natural gas paired with pipeline constraints.

New NStar undersea cable is expected to add redundancy to Vineyard power system and make service more reliable. The cable stretches 29,000 feet from Falmouth to West Chop.
