Saint Paul, Minn. Midwest Reliability Organization’s (MRO) annual winter assessment projects the region will have sufficient electricity supply to meet demand during the upcoming winter months (December through February) under normal peak demand conditions with typical maintenance and forced outages. For the first time in several years, the entire region is also expected to meet operating reserve requirements under extreme peak demand scenarios, despite record demand levels set last year.

The assessment also identified significant improvements in winter weather operations following severe winter storms Uri (2021) and Elliot (2022), due in part to revisions to winter weather reliability standards and increased winterization outreach efforts.

MRO’s 2025 Regional Winter Assessment provides key stakeholders with critical insights into potential reliability challenges and recommends actions to mitigate risks. The report also highlights bulk power system performance trends specific to the MRO region to inform long-term system planning.
