Brentwood BESS Project
Brentwood BESS Project
We are proposing the Brentwood Battery Energy Storage System (BESS) in the Township of Clearview in response to the Independent Electricity System Operator’s (IESO) procurement process to increase electricity capacity in Ontario. Brentwood 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.
Brentwood 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
Proponent: Brentwood BESS Limited Partnership
Name: Brentwood Battery Energy Storage Project
Type of Facility: Standalone Battery Energy Storage System (BESS) with factory-built modular containers
Location: Concession Road 2 & County Road 10, Clearview
Nameplate Power Capacity: 200 MW
Duration: 4 hours
Number of Acres: 5-10
Operation Length: From 20-30 Years
Target Operations Date: May 2027
Open House
On November 14th we hosted our community Open House in the Brentwood Community Centre. We’d like to thank everyone who attended, asked questions, and gave their feedback. If the project moves ahead, we will be holding further engagements with the municipality and the community, as we seek ongoing feedback about the project. If you have additional questions, please contact us.

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 value 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 landowners and securing land. Pending project approval from the IESO in late 2023, 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 2027.
