Using renewable resources to make electricity

Our generation portfolio includes environmentally sound renewable energy sources: wind energy, refuse-derived fuel and hydropower.

Great River Energy (GRETM) is looking at ways to further diversify its energy portfolio by exploring biomass, fuel cells, clean coal and other technologies as they become available, and we are developing a solar installation.

Under Minnesota’s Renewable Energy Standard we are required to produce 25 percent of our electricity using renewable energy sources by the year 2025. GRE currently meets or exceeds state renewable energy requirements.

Wind energy

We purchase the electric output from six wind projects in Minnesota, one in Iowa and one in North Dakota for 469 megawatts of renewable energy.

Biomass, a renewable energy source, is biological material derived from living, or recently living organisms, such as wood, waste, (hydrogen) gas and alcohol fuels. In Minnesota waste-to-energy power plants, such as Great River Energy’s Elk River Energy Recovery Station, are considered biomass plants.

Hydroelectric power

One of Great River Energy’s oldest sources of generation is hydropower from Western Area Power Administration (WAPA) dams. Currently, 100 MW (summer rating) of hydropower for our member cooperatives comes from WAPA.
