Clearway Energy Group (Clearway) announced the completion of Partridgeville and Wilmarth, two new community solar projects paired with energy storage. The projects reached commercial operations and completed commissioning in May. The projects will boost grid reliability and climate resiliency in the Commonwealth while also contributing to the state’s energy storage target of 1,000 MWh by the end of 2025.

“As storage continues to play a growing role in the renewable energy industry, we are thrilled to bring online Clearway’s first solar plus storage assets in Massachusetts,” said Craig Cornelius, CEO of Clearway Energy Group. “We thank Governor Baker’s administration and the Department of Energy Resources for making solar plus storage a policy priority and the towns of Athol and Plainville for the opportunity to work together to bring these projects to fruition. We’re proud to be a part of the Bay State’s path toward clean, local energy and creating economic opportunity right in the communities where we operate.”

Construction of both the Wilmarth and Partridgeville projects started in mid-2019 and primarily took place in the summer and fall months. Details of the projects can be found below:

• Partridgeville: 3.3 MW solar paired with 4 MWh energy storage provided by IHI, located in Athol, Massachusetts.
• Wilmarth: 5 MW solar paired with 4.6 MWh energy storage provided by NEC ES, located in Plainville, Massachusetts.

Under Massachusetts’ SMART program, solar paired with storage provides power quality support, allows for rapid ramping to reduce the intermittency of solar, allows for energy generation to be shifted to reduce peak demand, and reduces strain on the distribution system during times of low load and high solar generation. Partridgeville, Wilmarth and Clearway’s additional forthcoming community solar and storage projects in Massachusetts were designed and constructed to achieve those requirements.
