Defining Sustainability

for Otter Tail Power Company

For us, sustainability is a balance of responsible, resourceful action across four key areas.

Energy and Technology

Diversity in our energy portfolio enables us to deliver reliable, low-cost energy by staying up to date with changing market conditions. As we introduce new energy sources and technologies, our priority remains the same—meeting our customers' needs.

Environment

Energy requires natural resources. That's why we're putting our efforts into reducing our environmental impact across operations and helping customers use energy efficiently at home.

Community

Our connection to the communities we serve goes beyond providing electricity. Whether it's through our Otter Tail Power Company Foundation or helping light up the holidays, we partner with our communities to create vibrant places for people to live.

Economy

We help customers power our local economies and create new opportunities. We're committed to achieving financial growth and success for our company and the rural communities we serve.

Sustainability Stories

Respecting the past, looking to the future

After 100 years of coal-fired energy generation, we retired Hoot Lake Plant in 2021. To replace the energy generated by Hoot Lake Plant, Merricourt Wind Energy Center and Astoria Station, a natural gas combustion turbine, fulfill customers’ energy needs, as will Hoot Lake Solar, schedule to be completed in 2023. Hoot Lake Solar will not only generate renewable energy but enable us to maintain reliable and economically viable energy for our customers in an evolving energy industry.

A commitment to conserving energy

Our commitment to a reliable and affordable energy future doesn't stop at the energy we generate. To help customers conserve energy and manage their electric bills, we’ve developed programs that provide education on new technologies, outlined rate information to help calculate operating costs, and encouraged participation in energy efficiency programs. Last year marked both our largest investment in energy conservation programming and some of our customers’ largest energy savings in our 30 years of partnership across Minnesota and South Dakota.
