The owner of the closed Pilgrim Nuclear Power Station in Plymouth has lost an appeal seeking to release radioactive wastewater into Cape Cod Bay as part of the plant decommissioning.

The bill would repeal a 1982 state law that blocks the construction of any new nuclear power plant unless voters approve it in a statewide ballot.

Eversource is at work on improving its electricity delivery system to Martha's Vineyard.

The Marine Renewable Energy Collaborative will continue to test renewable tidal turbines at the Bourne Tidal Test Site at the Cape Cod Canal. A new federal license will allow testing for eight years.

“The power grid out here on Cape Cod, it's storm-prone,” said Bill Quinlan, president of transmission and offshore wind projects for Eversource.

A prototype undersea turbine being installed in the Cape Cod Canal may help clean energy developers find ways to harness tidal power.
