Your Power Supply

The cost to create and deliver electricity is composed of three general functions: generation, transmission and distribution. Dakota Electric Association is an electric distribution cooperative that purchases electricity from Great River Energy (GRE) a generation and transmission cooperative in Maple Grove, MN. Great River Energy is the second largest electric power supplier in Minnesota and one of the largest generation and transmission cooperatives in the country.

How does electricity work?

1. Great River Energy’s generating sites produce electricity.

2. Great River Energy’s transmission lines carry large amounts of electricity from a generating site to a substation.

3. At a Dakota Electric substation, electricity is converted from transmission power to distribution power.

4. Dakota Electric’s distribution lines carry electricity to homes and businesses.

Some homeowners and businesses have installed solar panels, wind turbines or other generators. They use these to help power their homes, but still use the grid to bring electricity to their homes when the sun isn’t shining or the wind isn’t blowing. During the times they generate more electricity than they need, they may sell that additional electricity to their Dakota Electric.
