Spray

The Spray hydroelectric facility is one of three TransAlta plants on the Spray system, which is part of the Bow River Electric System in Alberta. The plant uses the Spray Lakes storage reservoir which is created by the Canyon Dam, to the south, and the Three Sister Dam, to the north.

The Spray plant generates an average of 210,000 megawatt hours annually.

TransAlta's hydroelectric plants primarily provide electricity during periods of peak electrical demand and ensure system stability. Their operating flexibility means they can start quickly to introduce hydro power within minutes, balancing out shortages due to unexpected outages, or providing power at times of high demand.

Environmental Highlights

Protection of the environment is an important part of our hydro power business, as is responsible water use. We continually work with environmental and community groups to ensure habitats are protected, and that all users’ needs are heard.
