Nemadji Trail Energy Center part of sustainable future

Nemadji Trail Energy Center part of sustainable future

System reliability is essential. The Nemadji Trail Energy Center, proposed by Dairyland and Minnesota Power/ALLETE in Superior, Wis., is a 625 MW combined-cycle natural gas facility. Flexible and responsive, it will serve as the "power behind the power" supporting renewable energy investments. It will also be an economic engine for the northern region.

Keeping our promise to diversify generating resources, Dairyland announced two major renewable energy investments earlier this year. We have a power purchase agreement for the 149 MW Badger State Solar facility. The proposed project, developed by Ranger Power, will be constructed on privately-owned land in Jefferson County, Wis., with planned operation in 2022.

Dairyland is working again with Avangrid Renewables for 52 MW of wind energy from the proposed Tatanka Ridge II facility in Deuel County, S.D. We have existing agreements with Avangrid for the Winnebago and Barton wind farms in Iowa.

Together, Badger State Solar and Tatanka Ridge Wind will generate enough renewable energy to power over 40,000 homes. Dairyland also purchases the energy produced by the 98 MW Quilt Block Wind Farm, owned by EDP Renewables, in southwestern Wisconsin.

All 18 solar sites located in the service areas of Dairyland’s member cooperatives in Wisconsin, Minnesota, Iowa and Illinois are online for a total of 25 MW. Dairyland has power purchase agreements with ENGIE (formerly SoCore Energy) for 17 of the sites and groSolar for one. Many of Dairyland’s member cooperatives multiplied their local renewable energy benefit by piggybacking onto the utility-scale sites with community solar gardens.

Dairyland also purchases energy from three other major solar installations and several smaller wind farms. In addition, there are 1,650 consumer-owned distributed generation installations in Dairyland’s service area.

The Nemadji Trail Energy Center will support renewable energy resources like solar and wind. It will be able to ramp up in minutes, providing a reliable backbone to the system at times when other resources are unable to produce adequate electricity to meet consumer needs. Far beyond convenience, this is a potentially life-saving factor during times of extreme weather.

The regulatory process for the Nemadji Trail Energy Center is proceeding in Wisconsin. The plant is scheduled to be in service by 2025, contingent on approvals. For more information, see
