January 22 (Renewables Now) - A 4.5-MW solar plant coupled with a 1.6 MW/3.8 MWh battery storage system has been connected to National Grid’s network in Massachusetts.
The power plant was developed, financed and built by Kearsarge Energy LP, in partnership with NEC Energy Solutions (NEC) for the energy storage component. A ribbon-cutting ceremony marking the completion of the project was held last week, the partners said on Wednesday.
The solar-plus-storage installation, located on a former pit landfill in Amesbury, is expected to generate 5.2 million kWh of electricity per year, which will be enough to supply around 440 homes and offset 4,000 tonnes of carbon dioxide (CO2) emissions. Kearsarge will be the owner and operator of the facility, providing energy capacity services for the NE-ISO market.
On the heels of the project, Kearsarge and NEC plan to sign a master supply agreement this week under which Kearsarge will integrate NEC’s batteries into its solar projects. The Amesbury scheme was the first one in Kearsarge’s 250-MW pipeline to incorporate energy storage, the company noted.
