Brookfield Renewable Partners with TransAlta to Retire and Convert Coal Production

TransAlta is one of Canada’s largest producers of wind power and Alberta’s largest producer of hydroelectric power. In 2020, Brookfield Renewable closed a C$400 million investment, injecting capital required for TransAlta’s coal-to-gas conversions and to fund the build-out of TransAlta’s renewable electricity portfolio.


Since Brookfield Renewable’s investment, TransAlta has completed the conversion to gas at their Alberta facilities formerly fueled by coal, and retired their Highvale coal mine effective December 31, 2021. In total, TransAlta has retired 3,904 MW of coal‑fired generation capacity since 2019 while converting 1,659 MW to natural gas. As a result, TransAlta has reduced their total GHG emissions by over six million mtCO2e, a 37% reduction in two years, while increasing their renewable energy capacity to 2,900 MW, enough to power 1.8 million homes.1

Today, TransAlta’s diversified renewable fleet makes the company one of the largest renewable power producers in North America, wind power producers in Canada and hydro power producers in Alberta.
