Solar-plus-Storage Goes Community-Scale in Massachusetts

A small Massachusetts town already well-known for its solar-plus-storage microgrid, now will get a boost from the installation of a community solar-plus-storage project.

Miami-based Origis Energy USA said it has secured a power purchase agreement with the Sterling Municipal Light Department (SMLD) of Sterling, Mass, for the project.

According to Origis Energy, the project, which represents the first community solar-plus-storage project in Massachusetts, includes a 1-MWac rooftop solar installation with a 1-MW/2-MWh energy storage system.

“We are approaching the Light Department’s self-imposed cap on commercial solar capacity,” Matt Stelmach, chairman of the SMLD Board of Commissioners, said in a statement, “but introduction of a grid-scale battery system greatly reduces any concerns along those lines.”

SMLD previously installed an energy storage system with 2 MW of lithium-ion batteries with four hours of continuous discharge. The storage system and a 3-MW solar array can be islanded in the event of emergency.

Construction on the new community solar plus storage facility will begin this month, and Orgis said it expects to complete construction by the end of March.
