Founded in 1907, Otter Tail began with a vision to bring reliable electricity to communities across the Upper Midwest. For decades, our focus was clear: build and operate a strong electric utility that helped communities grow and thrive. As the region expanded, so did we, investing in the infrastructure and expertise needed to provide safe, reliable and affordable energy.
In 1989, we began a new chapter by expanding beyond our utility roots. Through disciplined and intentional diversification, we built a portfolio of successful businesses that complemented our electric foundation and created new opportunities for growth.
More than a century after our founding, we remain committed to building strong businesses, investing for the future and creating lasting value through disciplined growth and operational and talent excellence.
