PowerOn Midwest

PowerOn Midwest

PowerOn Midwest Tomorrow's reliability starts today.

PowerOn Midwest is a series of new electric transmission projects anchored by a 765 kV backbone transmission line being developed by Great River Energy, ITC Midwest, Otter Tail Power Company and Xcel Energy. The projects will connect eastern South Dakota, southern Minnesota and the broader region, enhancing grid reliability in the Upper Midwest to meet growing and evolving energy needs in the coming decades.

Regional energy use

PowerOn Midwest will support communities in southern Minnesota by better connecting the local lines serving local load and generation to the resources of the wider region. Each substation along the PowerOn Midwest route is a key grid connection point where electricity can flow onto or off the transmission system, helping move power between generators and local consumers.

Power will flow in both directions through these lines and substations throughout the year depending on weather conditions. Take a look at the animation: when it is windy in the west and calm in the east, excess power generated by wind turbines in the west will flow on the lines and serve the load to the east. A few hours later when the weather pattern shifts east, the flows reverse and excess power from wind turbines in the east flow to serve customers in the west. This also applies to when customer’s cooling or heating needs increase electricity usage, and when cloud cover impacts solar panel output.

Key benefits

  • Reliable electricity

    Delivers on our commitment to customers that electricity is delivered where and when it's needed—regardless of the weather, electric generation source, or demand.

  • Future-ready grid

    Addresses rising electricity demand, which is projected to grow significantly over the next two decades.

  • Customer and economic benefits

    Enables more cost-effective generation while improving reliability, opening doors for future economic growth across the region.

  • Access to new electric generation

    Supports a range of energy sources added to the grid, providing a balanced and reliable power supply for the future.

Preliminary schedule

Developing and building major new transmission lines is a multi-year process that begins with significant planning, which identifies general project areas, includes comprehensive outreach to local landowners and officials to explore potential route options, and involves a robust regulatory review by state officials. If approved, construction would begin in 2030, with segments expected to be in-service between 2032 and 2034.

As our schedule evolves, we will provide updated information.

Where and how we use and generate power is changing.

As large, aging power plants are retired in the coming years, we're shifting to other forms of generation that can be more flexible and scalable for our region's new energy needs.
