BOSTON, Aug. 17, 2026 /PRNewswire/ -- Kearsarge Energy announces the 2026 implementation of four new Battery Storage Energy System (BESS) projects this year totaling 70 MWH, and an expected construction of 200 MWH in 2027. Kearsarge has been the Northeast's leader in Battery Storage since installing National Grid's first DG PV+BESS system in 2019 in Amesbury, MA. In the subsequent 7 years, through Covid and constant regulatory turbulence, Kearsarge has been a driving force behind battery energy storage adoption with utilities, technology partners, and municipal stakeholders by pushing innovative financing, leading in safety protocols and standards, and integrating best of class BESS technology and components to deliver high performance and value across multiple incentive program as well as ISO-NE wholesale markets. Consisting of standalone BESS and Solar + BESS, these projects represent public-private partnerships with municipal hosts as well as private development. The 2026 portfolio includes PV + storage at landfills, as well as standalone BESS installations, with Municipal, non-profit and quasi-public partners.

Project Highlights:

Amesbury, MA 3.8 MWH, Standalone, completed in 2019. Solar + BESS located at the City's Titcomb Pit Landfill, this project was the first solar + storage facility built under the MA SMART Solar Program in National Grid territory. The facility consists of a 4.5 MW DC ballasted array, and a 3.8 MWh BESS.

Montague, MA 5.1 MWH, Standalone, completed in 2021. Kearsarge helped facilitate the closure of the Town's burn dump waste site where this Solar + ESS is located. This is another example of Kearsarge's commitment to public-private partnerships. The facility consists of a 3.0 MW DC solar facility, and a 5.1 MWh BESS.

Haverhill, MA 9.0 MWH, Standalone, completed in 2021. Solar + BESS located at the City of Haverhill's landfill connecting to the local National Grid distribution grid. Kearsarge worked closely with the MA DEP and EPA to permit the project on a former superfund site. The facility consists of a 3.6 MW DC solar facility, and a 9.0 MWh AC coupled BESS.

William Way, MA 9.55 MWH, completed in 2021. Located on underutilized land owned by the Town of Bellingham, MA this project provides over 6.6 million kWh of renewable electricity annually to public entity offtakers in National Grid territory. The facility consists of a 6.3 MW DC solar facility, and a 9.6 MWH AC coupled BESS.

Beverly, MA 6.8 MWH completed in 2022. Kearsarge Energy partnered with the City of Beverly, Massachusetts, to develop six solar projects totaling over 4 MW across various city-owned properties. This landmark project for Beverly included the decommissioning of an existing solar array at Beverly High School. Kearsarge replaced the existing array at Beverly High school with industry-leading modules and racking, increasing capacity and installed a carport facility, and a 6.8 MWH AC coupled BESS.

Kingston, MA 4.45 MWH, completed in 2022. Solar + BESS located at the Town of Kingston's landfill site connected to the Eversource distribution grid. The facility consists of a 2.7 MW DC ballasted ground mounted solar facility, and a 4.5 MWH DC coupled BESS after decommissioning an abandoned wind turbine.

Franklin, MA 3.88 MWH, completed in 2022. Solar + BESS situated on underutilized land in Franklin, MA connecting to the local National Grid distribution grid. The facility consists of a 1.5 MW DC solar array, and a 3.9 MWh DC coupled battery BESS.

Reading, MA 22.4 MWH, completed in 2025. Kearsarge developed this 22.4 MWh standalone BESS in partnership with the Reading Municipal Light Department in order to shave local peak demand during key events, while contributing to reduced ISO NE peaks – resulting in meaningful sustainability, reliability and economic impacts. 

Orleans, VT 20 MWH, completed in 2025. In partnership with Vermont Public Power Supply Authority and local light departments in Orleans and Barton, Vt, Kearsarge built a 20 MWH standalone BESS which reduces local peak demand during key grid events for the host municipal light departments, while a nearby 7.5 MW solar array provides over 8.7 million kWh and renewable energy credits annually, meeting VT state requirements and contributing local domestic energy to the region.

Sterling, MA 20 MWH, completed in 2025. Solar + BESS generates local in territory energy for the Sterling Municipal Light Department and supports their management of peak load. A Solar ground mount array on underutilized private land generates over 2.2 million kWh annually, and the 20 MWh BESS offsets peak energy demand resulting in energy cost savings for the local light department.

Concord, MA 20 MWH, Standalone. A Solar + BESS under construction at the Town of Concord's Walden Street landfill will generate local in-territory energy for the Concord Municipal Light Plant while also peak shaving. By pairing a 20 MWH BESS with a 4.6 MW DC ballasted solar array, Kearsarge and CMLP have enabled a significant increase in solar production.

Middleborough, MA 20 MWH, Standalone. A 20 MWH standalone BESS will reduce local peak demand during key grid events for the host municipal light department, Middleboro Gas and Electric. The project is expected to save Middleboro Gas and Electric an estimated $12,000,000-$15,000,000 over 20 years.

Chicopee, MA 20 MWH, Standalone. Continuing its commitment to a public-private partnership with Chicopee Electric Light, first started in 2012. Kearsarge is constructing this 20 MWH standalone BESS that will reduce local peak demand during key grid events.

Walpole, MA 10 MWH. Solar + BESS located on Norfolk County owned land that will be connecting to the Eversource distribution grid. The facility will consist of an approximately 6.9 MW DC ballasted ground mounted solar facility, and a 10 MWH AC coupled BESS as another Kearsarge addition part of the Massachusetts SMART program.

Kearsarge owns and operates all of its total energy portfolio, working closely with local stakeholders, power authorities, electric cooperatives, municipal light departments and other partners across the country to optimize development and performance. In 2026, Kearsarge, one of the largest Independent Power Producers in the Northeast, will commission 4 BESS projects in Massachusetts working in close cooperation with those partners to drive energy storage, and pioneer best practices in safety and efficient market operations for these assets. 

Andrew Bernstein, Managing Partner of Kearsarge Solar remarked, "Leading safe and efficient storage adoption has been incredibly rewarding over the past seven years. Through our work with municipalities and local utilities we have helped those organizations think through how to take advantage of Battery storage opportunities in a sustainable way, to meet the accelerating energy demands of their communities and drive affordability for desperately needed new generation."
