Nexamp constructs new solar + storage facility

Nexamp Non-Wires Alternative Solution

Nexamp, together with National Grid, announced the construction of a new solar + storage facility for addressing energy demand at the Coffeen substation in Watertown, New York.

Nexamp’s solar + storage facility will eliminate the need for additional transmission lines or substation upgrades through a Non-Wires Alternative (NWA) approach and reduce cost and complexity by using distributed energy resources.

The Watertown Renewables project features more than 20,000 solar panels generating 8.4 megawatts (MW) of renewable energy and 10 Tesla Megapack systems providing 31 megawatt hours (MWh) of energy storage.

The solar and storage components of Watertown Renewables are engineered to give National Grid the ability to call on the system for up to 5.7 MW / 29 MWh up to 25 times per year either from the panels or the batteries.

“This project is significant because it represents a number of important firsts,” explained Chris Clark, Chief Development Officer, Nexamp. “It is our first NWA project and is the result of a lot of hard work and collaboration between Nexamp and National Grid.”

Watertown Renewables will serve area residents through the company’s Community Solar program, providing energy costs savings to subscribers while delivering a new source of renewable energy to the local grid. This project is capable of offsetting the energy needs of more than 1,000 local residents who get their electricity from National Grid.

Nexamp has dozens of other solar + storage projects already in operation across the Northeast and around the country. The Watertown Renewables project is expected to be completed early next year.
