Bighorn

The Bighorn Plant is TransAlta’s highest performing hydro plant, producing an average of 408,000 megawatt hours each year.

When TransAlta built the Bighorn Hydro Plant, it created Lake Abraham — Alberta’s largest man-made lake. The plant is one of two TransAlta hydro plants on the North Saskatchewan River System in Alberta.

In addition to TransAlta’s hydro plant, Bighorn is a name given to a lake, river, creek, canyon and mountain range in western Alberta because of the abundance of Bighorn sheep.

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.

We are also working to enhance the environmental component of our Environment, Health & Safety Management System to meet ISO 14001 standards (ISO 14001 is an international standard setting the framework for a holistic and strategic approach to environmental policy, plans and actions).
