IESO Engagement – 2024 Annual Planning Outlook

Manitou River

Recent hydropower shortages in BC, Alberta, Manitoba and Saskatchewan have highlighted its vulnerabilities in the face of the extremes of climate change. Hydropower is reliant upon water availability, so during the low-flow season or in times of drought, it can become intermittent and unreliable. As noted above, ongoing drought is already affecting hydropower output, and many provinces are being forced to import power or turn on the coal and natural gas facilities. Reliable hydropower does not bode well for the future.
