Energy Generation

Delivering reliable, low-cost, and responsible power for decades to come

Our generation mix includes coal-fired plants, wind power, combustion turbines, solar power, and hydroelectric plants. We also purchase electricity from the Midcontinent Independent System Operator, or MISO, energy market when buying it is more economical than generating it ourselves. This mix ensures reliable, low-cost, and increasingly clean electricity 24 hours a day, 7 days a week.

Our energy mix

The Merricourt Wind Energy Center harnesses some of our nation's best wind resources to generate clean, low-cost energy. Its 75 wind turbines produce enough energy to power 65,000 homes annually.

Astoria Station fills gaps when customer demand for energy is high or conditions for renewable energy aren’t ideal. This quick starter is nimble and able to ramp up swiftly, generating electricity in less than ten minutes.

Hoot Lake Solar, our first large-scale capital investment in solar generation—approximately $62 million—was completed in August 2023. Its 130,000 solar panels generate enough energy to power 9,000 homes annually.
