TransAlta Corporation

TransAlta Corporation is a Canadian-based electricity power generator and wholesale marketing company headquartered in Calgary, Alberta. Its mission is to deliver responsible energy solutions that customers and communities can count on. The company, founded in 1909, is one of Canada's largest publicly traded power generators.

TransAlta operates a diverse portfolio of power generation assets, including hydro, wind, solar, and natural gas facilities, across Canada, the United States, and Australia. The company provides electricity and wholesale energy marketing services, along with asset management, optimization, and risk-management solutions to a broad customer base, including utilities, industrial clients, municipalities, businesses, and residential consumers. TransAlta is actively transitioning its energy portfolio towards cleaner sources, aiming to be off coal-fired generation by the end of 2025 and achieve net-zero emissions by 2045.

In recent leadership changes, Joel Hunter is set to become President and CEO in early May 2026, succeeding John Kousinioris, with Mike Politeski appointed as CFO and Grant Arnold as Chief Commercial Officer. The company continues to expand its operations, including a recent Memorandum of Understanding for data center development at its Keephills site. TransAlta has also significantly bolstered its market position in Alberta by acquiring Heartland Generation in November 2023, giving it control over 46% of the province's electricity generation market. The company is currently seeking to recover costs related to its Centralia plant due to a U.S. Department of Energy order.
