Eversource Energy is working out a lease agreement with Provincetown, Mass. to site a 25-megawatt energy storage facility at the town’s transfer station. The energy will be used to “increase reliability and supplement the electric infrastructure for Cape Cod and Martha’s Vineyard,” according to the Cape Cod Times.

The newspaper reports that the 7,600-square-foot facility would help build more redundancy in the Outer Cape’s electric system, where there currently is little room for expansion. In other areas where there are back-up systems, Eversource can re-route power when lines are down. But in places like Provincetown, which is prone to blackouts during bad storms, that isn’t possible because of its location at the tip of a peninsula.

According to Eversource, the new battery storage system could help reduce power outages from Wellfleet to Provincetown by 50%.

Eversource is also planning a 5-megawatt energy storage project to help Martha’s Vineyard handle high peak loads in the summer.

The two Eversource projects approved by the state will be its first storage facilities. The company has been authorized to recover $55 million to pay for them through rates in the future

Energy Initiatives on the Massachusetts Islands

In September, the Otis Microgrid project, the first of such a broad scope for a Department of Defense installation, announced it will provide electrical capabilities almost exclusively based on renewable energy while ensuring a high-level of grid security. The energy security and resiliency provided by the microgrid is critical to the 24/7 mission of the 102nd Intelligence Wing, a military intelligence unit located at Otis Air National Guard Base on Cape Cod.

And in October, Momentum Dynamics, a charging technology company for the electric automotive and transportation industries, announced that Vineyard Transit Authority (VTA) has approved the purchase of high-power wireless charging systems from Momentum Dynamics to support zero-emission electric transit buses. VTA serves the community of Martha’s Vineyard and is the first transit agency in Massachusetts with plans to convert all diesel buses to battery electric.
