As a leading renewable energy project developer, financier, and long-term owner and operator, Kearsarge Energy L.P. creates recurring value by working with local communities to meet the growing demand for commercial and utility-scale renewable energy projects.
Kearsarge partnered with Stem to operate a large-scale, front of meter energy storage system located on a former landfill in Haverhill, Massachusetts. The 2MW / 9MWh energy storage system, paired with 3.6MW of solar PV generation, is the largest Massachusetts project that participates in New England wholesale energy markets through Stem’s existing partnership with Kearsarge.
Focusing on distressed municipal holdings like brownfield sites, Kearsarge aims to augment renewable energy generation with battery energy storage to reduce wholesale demand charges, increase grid resilience and maximize energy savings. Energy storage expertise was needed to provide market bidding, dispatch scheduling, data management, and performance reporting.
Stem assisted Kearsarge with project management and leverages our Athena software to enable projects to deliver value via ISO New England wholesale markets and Massachusetts’ Clean Peak Standard. Athena also supports incentive compliance with the federal investment tax credit and the Solar Massachusetts Renewable Target (SMART) program.
Since the announced partnership in September 2019, Stem has partnered closely with Kearsarge on a growing portfolio of large-scale solar plus storage projects. The Haverhill project will result in energy savings, lease revenues, maintenance and upkeep savings, and tax payments estimated to total at least $3.9 million for the city over the project’s lifetime.
