Rabbit Battery Energy Storage Project

Cumberland, Ottawa, ON

In Development




45 MW


Cumberland, Ottawa, ON

About the Project

The Rabbit Battery Energy Storage Project directly responds to the Independent Electricity System Operator’s (IESO) call for additional capacity to meet Ontario’s growing electricity consumption. The Project would be located on private land in Cumberland, Ottawa and represents a cost-effective solution to add capacity, enhance flexible grid operations, and save greenhouse gas (GHG) emissions in Ontario by reducing the need for carbon-intensive power plants during times of peak demand.


The Project is in the feasibility stage and is expected to be operational by May 2025, subject to the IESO determining the Project to be best for Ontario ratepayers. If approved, the proposed Project will consist of installing battery modules and some overhead infrastructure.

  • Initial investment of ~$120 million
  • Capacity of 45 MW and 180 MWh of energy storage
