Cobourg BESS Project
Cobourg BESS Project
We are proposing the Cobourg Battery Energy Storage System (BESS) in the Township of Hamilton in response to the Independent Electricity System Operator’s (IESO) procurement process to increase electricity capacity in Ontario. Cobourg BESS will help achieve the Government of Ontario’s objective to reduce the need for new generation capacity in the province and more effectively use existing generation facilities.
Cobourg BESS is designed as a standalone system with factory-built and modular containers and is expected to use industry-leading lithium-iron-phosphate (LFP) batteries. The facility will be located near a Hydro One Transmission Line.
Project Overview
Name: Cobourg Battery Energy Storage Project
Type of Facility: Standalone Battery Energy Storage System (BESS) with factory-built modular containers
Location: Burnham St N & Telephone Rd, Hamilton, ON
Nameplate Capacity: 75 MW
Duration: 4 hours
Number of Acres: 5-10
Operation Length: Up to 30 years
Target Operations Date: May 2027
Open House
On November 15th, we hosted our community Open House at the Baltimore Recreation Centre. We’d like to thank everyone who attended, asked questions, and gave their feedback.
Please find attached responses to questions asked at the Open House. We will be updating this document with additional questions shortly.

Why battery storage?
With demand for clean energy expected to outpace Ontario’s current generation capacity over the next decade, there is an urgent need for innovative solutions that will help meet our energy needs while contributing to our province’s climate change goals.
The Independent Electricity System Operator (IESO) is the operator of Ontario’s electricity grid and is undertaking a procurement process to identify Battery Energy Storage solutions to meet the needs of Ontario’s increasing electricity demand.
How battery energy storage systems work
Battery Energy Storage Systems charge a battery bank during hours of surplus energy generation in the grid, then discharge the battery bank during energy deficit hours to meet grid demand.
Storing energy when demand is low and releasing it when it is high optimizes the efficiency of our grid by creating a steady, affordable supply of energy when and where we need it most.
This solution will maximize the efficiency of our existing energy assets by increasing supply while reducing emissions.
BESS systems have numerous benefits to the overall stability of our electricity grid:
- Manages peak loads
- Maximizes efficiency of existing energy assets
- Reduces reliance on fossil fuels, contributing to lower emissions and cleaner air
- Balances generation of intermittent resources such as wind and solar
- In practical terms, can help avoid grid outages and blackouts
Construction Timeline & Activities
Straightforward construction over a four to six month period, to begin in late 2026. Major construction activities to include delivery of factory assembled battery containers and components, installation, and Hydro One interconnection.
We values local support for projects, and as such is requesting a municipal support resolution per IESO requirements which will allow the proposed BESS projects to proceed with remaining development.
We have begun engaging with municipal and Indigenious communities. Pending project approval from the IESO in mid 2024, We will undertake the required environmental and engineering surveys and studies with the goal of completing final design and receiving notice to proceed to construction in late 2026.
The current target commercial operational date for the proposed BESS projects is May 2027.
