Comber BESS Project

Lakeshore, ON

In Development




Up to 350 MW


Lakeshore, ON

About the Project

Brookfield Renewable Power Inc. (“BRPI”), is advancing the Comber BESS (Battery Energy Storage System) (“Project”) through its Canadian operating business, Evolugen, and Comber Batteries LP (the “Proponent”), a person controlled by BRPI. The Project directly responds to the Independent Electricity System Operator’s (IESO) call for additional capacity to meet Ontario’s growing electricity consumption. The Project will be co-located with Evolugen’s operating Comber Wind Farm on up to 20 acres of private land in Lakeshore 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 proposed Project will consist of installing battery modules near the operating Comber Wind Farm substation. 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.

  • Directly interconnected to IESO using Comber Wind Farm‘s existing 356 MW interconnection
  • Initial investment of ~$800 million
  • Capacity of up to 350 MW and ~1,400 MWh of energy storage

Evolugen is committed to building trust with local stakeholders and engaging proactively with communities to ensure that their interests are appropriately considered in our decision-making. The Project will follow this commitment and will be located in a remote location with:

  • Minimal biodiversity and noise impact
  • Minimal traffic when facility is operational
  • Increased electricity supply and reliability
  • Reduced chance of outages in the network


As part of our commitment to building trust with local stakeholders, community members are invited to share project comments, questions and concerns by email at We hosted five Community Engagement Meetings to gather feedback and answer questions. The Meeting Minutes can be found below.
