East River Electric is a power supply cooperative that delivers wholesale power to 24 rural electric distribution cooperatives and one municipally-owned electric system in eastern South Dakota and western Minnesota.

As an electric cooperative, we exist to enhance the value of our member-owners by providing power, information, and innovation.

We support renewables. The current wind and hydropower generation mix in our wholesale power supply is 40 percent.

From sponsoring community events to volunteering for local causes, we're committed to advancing the communities we service.
