Canada: Ameresco has completed a 4 MW, 16 MWh energy storage project for Ontario’s Independent Electricity System Operator (IESO).
The project began four years ago when Ameresco secured two energy storage facility agreements with IESO to design, build, own and operate the “Battery Solid” storage systems. The two solid-state lithium-ion battery systems connect to the Newmarket-Tay Power Distribution grid at a capacity of 4 MW.
Both systems absorb power during periods of excess energy supply and deliver it back to the grid when energy demand is high. This project also demonstrates the value of future ancillary services, which would allow IESO to charge or discharge instantly to provide frequency regulation, voltage control and spinning reserve services to the grid, according to Ameresco.
