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.

A noteworthy chapter

2021, and the many months leading up to it, was a noteworthy chapter in our company history. From bringing Merricourt Wind Energy Center and Astoria Station on line to retiring Hoot Lake Plant and planning for Hoot Lake Solar, we've had a lot going on! Enjoy this 12-minute documentary about our historic year.

We retired Hoot Lake Plant in May 2021, marking the end of 100 years of coal-fired energy generation at the site. The plant played a vital role in our history.

We built Merricourt Wind Energy Center to replace the energy produced by Hoot Lake Plant. Its 75 turbines harness some of our nation’s best wind resources.

Astoria Station fills gaps when demand for energy is high or conditions for renewable energy aren’t ideal. It can generate electricity in less than ten minutes.

And in 2023, we expect to complete Hoot Lake Solar, providing additional renewable energy. The site will generate enough energy to power approximately 10,000 homes each year.
