New York-based Convergent Energy + Power has won a contract to install a valve-regulated lead acid (VRLA) battery storage plant in Boothbay Harbor, Maine, US.
The battery storage system is to feed 500kWh continuously to the grid. The system will be part of Central Maine Power’s (CMP) plan to provide load reduction on its transmission line to the Boothbay region and to prevent outages during peak hours.
Convergent said it expects the facility to be operational by mid-September.
“This is going to save everybody money and more importantly prevent outages,” said Convergent’s chief operating manager Frank Genova.
Portland-based renewable energy company Grid Solar contracted Convergent for the VRLA storage system. “After the 10-year agreement ends, we expect to renew the contract for another 10. All the assets would be paid for and we can repower the module at a cost 15% less than the original cost. This means more savings for everybody,” said Genova.
Convergent plans to develop 400MW of energy storage by 2020.
