About the Project
TransAlta is proposing to augment the Brazeau Hydro Facility by adding a battery energy storage system (BESS) to each of its two existing hydro generators. The BESS systems are anticipated to be approximately 10-megawatts (MW) each and will be situated adjacent to the existing substation on previously disturbed lands.
What is a Battery Energy Storage System?
BESS consists of battery cells grouped together into modules. Battery modules are housed in containers or enclosures similar in size to a shipping container.
The batteries are projected to have a lifespan of 20 to 25 years. At the end of their useful life, the batteries will be disposed of or recycled according to environmental regulations and the manufacturer’s recycling programs.
TransAlta’s WindCharger Project was the first utility-scale BESS project developed in Alberta and has been in operation since 2020.
Health and Safety
TransAlta is currently developing a project-specific Emergency Response Plan (“ERP”) to be submitted with the AUC Rule 007 application. When the project has been constructed, the ERP for the existing Brazeau facility will be updated to include the facilities associated with the Brazeau Hydro Hybridization Project.
To develop the ERP, TransAlta will engage with local Indigenous communities and First Responders to identify important elements to be considered.
Public Information Session
TransAlta is seeking feedback on our proposed Brazeau Hydro Hybridization Project, to be co-located with our existing facility at Brazeau. As part of our consultation and engagement plan, we are planning a public information session.
Public Information Session
October 2, 2025 from 3 – 7 PM
Location: Lodgepole Hall, 4501 52 Avenue, Lodgepole, AB
TransAlta will continue to engage with Indigenous communities and local stakeholders throughout the development of the Project. More Project details will be shared as the project advances. We value your input and encourage your participation.
