Great River Energy announced plans in the spring of 2020 to transform its portfolio of power supply resources in the coming years. The electric cooperative plans to phase out remaining coal resources, add significant renewable energy and explore critical grid-scale battery technology. These portfolio changes will deliver on the member-owners’ three highest priorities – affordability, reliability and environmental stewardship. The future portfolio will serve their member-owners for decades while significantly reducing wholesale power costs to its member-owners. Additionally, the cooperative’s power supply resources will be more than 95 percent carbon dioxide-free.
As part of this portfolio transformation, Great River Energy will retire its largest coal-fired baseload power plant, Coal Creek Station, in the second half of 2022 and add 1,100 MW of wind energy purchases by the end of 2023, taking advantage of cost-competitive renewable energy and reliable access to market energy. It will also modify its coal and natural gas-based Spiritwood Station power plant to be fueled by natural gas. Finally, it will install a 1 MW, long-duration battery demonstration project, fostering innovation as the technology of the industry evolves.
