Climate change management
Energy transition is at the core of our business
The energy sector continues to evolve, driven by customer needs, technological advancement and policy development. Delivering affordable and reliable power during this evolution requires a balanced mix of energy sources.
Since 2018, we have retired 4,464 megawatts (MW) of coal-fired generation capacity and converted 1,659 MW to natural gas. In 2025, we announced an agreement to convert our remaining coal facility to natural gas.
Today, we operate more than 60 renewable and energy storage facilities across Canada, the United States and Western Australia.
Our climate strategy in action
We are one of the largest wind producers in Canada
Today, we are proud to be one of the largest producers of wind power in Canada and the largest producer of hydro power in Alberta. We have grown our nameplate renewable energy capacity from approximately 900 MW in 2000 to ~3,600 MW in 2024.
We have reduced our GHG emissions
In 2025, we achieved our target of reducing scope 1 and 2 greenhouse gas emissions by 75 per cent from 2015 levels—one year ahead of schedule. Since 2015, these emissions have declined by 30.7 million tonnes of CO2e, representing a 76 per cent reduction.
We have a tangible decarbonization strategy
As a leader in North American renewable electricity, we are well-positioned to build renewable energy facilities and energy storage facilities to support customer decarbonization goals.
Climate change disclosure and reporting
We continue to monitor evolving disclosure requirements across jurisdictions in which we operate. Our climate-related disclosures are informed by:
- IFRS S2 Climate-related Disclosures
- Task Force on Climate-related Financial Disclosures (TCFD)
- Sustainability Accounting Standards Board (SASB) standards for electric utilities and power generators
