Project overview
Upgrading the equipment at BBGS will increase its generating capacity by 42.5 MW to an output capacity of 612.5 MW (at 15°C reference level ambient air conditions). The efficiency upgrades will be limited to replacing parts of the existing natural gas fired combustion turbines during an already scheduled maintenance period. All upgrade activities will take place within the existing building and there will be no changes or expansion beyond the existing BBGS footprint.
What’s being upgraded?
The efficiency upgrades will include replacing parts of the existing natural gas fired combustion turbines with more efficient parts that will allow increased electrical output. The work is similar to regular facility maintenance activities and will be confined to the existing facility footprint. There will be no changes or expansion beyond the existing BBGS footprint.
Environmental screening process and project timeline
Since the project will result in a 42.5 MW increase in the electrical output of BBGS, it is subject to the Environmental Screening Process for Electricity Projects subject to Ontario Regulation 116/01, under the Ontario Environmental Assessment Act. A Notice of Commencement of a Screening and Invitation to a Public Meeting was issued on July 26, 2023, to communicate the start of the Environmental Screening Process.
Request for exemption
Given that the proposed upgrades to BBGS are minor – similar to routine maintenance activities – and contained entirely within the footprint of the existing facility, Atura Power is requesting that the Ontario Ministry of Environment, Conservation and Parks grant an exemption to the Ontario Environmental Assessment Act for this project.
We want to hear from you
Atura Power is committed to engaging with Indigenous communities, the public, and other stakeholders on all our projects. We invite you to attend an upcoming virtual public meeting to learn more about the BBGS efficiency upgrades and provide feedback.
