Our Operations

Generating the safe, reliable and affordable power that millions depend on is made possible by our commitment to efficiency at all our operations. Our growing portfolio of assets powered by Solar, Wind, Hydro, Coal, Natural Gas and Energy Storage are necessary to maintain a healthy and stable electricity supply. With more than 70 power plants in Canada, the United States and Australia, we’ve acquired world-class development and operational expertise in generating clean power.

Clean, Reliable and Affordable Electricity

As part of TransAlta’s transition to clean power, we are in the process of converting up to seven of our coal-fired generating units to natural gas. As a leader in clean energy, TransAlta is taking large strides to convert the fuel source for its generators and use the existing plant sites to continue to provide Albertans with clean, reliable and affordable electricity.

Dedicated to Safety 

TransAlta is committed to protecting our people, the public, the environment and the company’s physical assets. Meeting this commitment is a corporate responsibility for TransAlta, and the personal responsibility of each employee and contractor working on TransAlta’s behalf. The public also plays a role by understanding how to be safe when near our operations.
