The Amphora project is comprised of a +/-4 MW (8 MW total range) / 2.6 MWh lithium battery that provides frequency regulation to the Independent Electricity System Operator (IESO) system; IESO is the grid operator for the province of Ontario. The project utilizes lithium iron phosphate batteries. There are two containers that house batteries weighing approximately 20 tons each, as well as a third container that converts the direct current (DC) output to alternating current (AC) for the injection and withdrawal of real power to and from the grid. The project was awarded to RES by IESO following a competitive tender.
