Grand Energy Storage Project

Pattern Energy Group (Pattern) and Samsung Renewable Energy Inc. (Samsung) is currently considering the installation of a Battery Energy Storage System (BESS) in proximity to the existing Grand Renewable Wind Farm located in Haldimand County, Ontario. The Grand Energy Storage Project (the Project) is expected to total up to 300MW.


Project Information

The Project will consist of battery storage enclosures, electrical inverters and transformers, internal access roads, electrical and communication cabling, a small transmission substation, and other related electrical and infrastructure facilities. The exact layout of the infrastructure footprint has yet to be confirmed and will be determined through additional engineering studies, equipment procurement, and an environmental assessment.

The battery storage project is expected to provide significant benefits to Ontario’s ratepayers by reducing the need and cost associated with using gas-fired power plants during times of peak demand.
