About the Project
RES is proposing to develop, build and operate a Battery Energy Storage (BESS) Project with a capacity of up to 240 MW, west of Inwood in the Enniskillen Township. Inwood Energy Storage Project (the Project) would provide the provincial electric system with reliability services needed to support increasing electricity demand. This would not involve any on-site electric power generation.
Project Site Map and Key Facts
All Project components together are expected to occupy no more than 30 acres, situated within a single parcel of land. It would be comprised of various technologies allowing the system to charge and discharge electricity on demand.
Project Components:
- Containerized batteries
- Inverters
- Medium voltage transformers
- Gravel internal access roads
- Collector and communication cabling
- Transmission substation
- Operations and maintenance building
The final layout of the infrastructure within the Project’s footprint has yet to be confirmed and will be determined through additional engineering studies, equipment procurement, and an environmental assessment. The Project will connect to an existing Hydro One transmission line located east of the proposed Project.
RES is preparing the project to bid into the IESO Long Term 2 Request for Proposals (LT2 RFP) in December 2025.
