Altus needed an expert storage partner that not only understood Massachusetts’ solar and storage incentives, but also offered industry-leading software that could maximize incentive payouts and comply with program requirements. Altus also wanted to deploy a DC-coupled system, which improves project efficiency but adds installation complexity.
Altus chose Stem partly for our proven Athena® software, which already optimizes solar plus storage systems across Massachusetts under the SMART program. Stem also worked closely with the utility during deployment to smooth integration with the utility’s system and increase the speed at which solar can provide power to the grid.
In addition to SMART program optimization, the New Marlborough project will capture revenues from Massachusetts’ Clean Peaks program, a generous incentive that compensates energy provided in the peak hour of each month. The project will also earn wholesale market revenues by providing energy, capacity, reserves, and regulation services to the grid operator, ISO New England.
