Power Supply / Management Engineering batteries Ontario power power gridLooking to add capacity to Ontario’s electricity grid, a battery energy storage project may be built near Brinston in the next couple of years.
Creekside Battery Energy Storage (BESS) is currently undergoing an Environmental Assessment to build a facility on a 15 acre property on the northwest corner of Gilmour Road and South Branch Road (north).
Will Patternson, project manager for the Creekside BESS project explained the EA is only one step towards the project breaking ground as it has not yet received a contract from the Independent Electricity System Operator for the facility.
“If we are successful, the earliest we would start construction is Spring 2025 and go online in 2026,” Patternson said. “But there are a lot of steps in-between.”
The IESO manages Ontario’s electricity supply and issued a Request for Proposal for battery energy storage projects as part of its long term plan to increase capacity on the province’s electrical grid.
Battery storage facilities will draw power from the grid during periods of excess power generation or when there is low demand for electricity, then return to the grid during times of peak use. The IESO will pay contractors both to store the electricity, and for the electricity when it is used in the grid.
The Creekside BESS project is designed to store 230 megawatts of power for four hours, the equivalent of 920 megawatt hours. That is nearly equal to the output of the R.H. Saunders Power Dam in Cornwall (1,057 MW).
The project is one of two in the area by Toronto-based renewable energy company Potentia Renewables Inc. that has submitted a proposal to the IESO RFP process. Another is proposed in Edwardsburgh-Cardinal.
Patternson said that the Gilmour Road location was proposed because of a number of factors including proximity to three high-voltage transmission lines, available land, and that the property size allows for a 500 metre set back from residences.
“The project fills a lot of voids in the electrical system,” Patternson said. “It’s like an insurance policy when electrical demand is high.”
The IESO will announce the successful bidders to its Resource Adequacy RFP in May 2024.
