MISO warns that the power grid in the Midwest, South, and Manitoba is ready for winter, but there are still risks.

It said that an assessment by Midcontinent Independent System Operator showed that there are enough resources to provide power during winter, but also highlighted the risks and challenges of cold and extreme weather operations.

In a press statement, MISO said that its annual Winter Readiness Workshop will take place on October 29, and include transmission and generation forecasts as well as weather predictions for the coming season.

Jason Howard, MISO director of operations and risk management, said that a clear understanding of risks was essential to stay ahead of extreme weather. The release stated that the winter forecast indicates near- to slightly-below-normal temperatures across MISO's North and Central regions, while the South region is expected to experience above-normal temperatures. MISO serves Manitoba, Canada.

It added that an active storm pattern will likely create above-normal rainfall across the Great Lakes region, while the South region is expected remain dry.

MISO said that the peak winter demand could be as high as 110 gigawatts. Last winter, MISO reached a demand of 108 gigawatts on 21 January 2025 during Winter Storm Enzo.
