Generating cleaner energy through innovation

At Great River Energy, we’re actively preparing for the future of energy production through innovative technologies, while continuing to provide reliable, affordable electric service to our member-owner cooperatives.

DryFining™ fuel enhancement system

The DryFining fuel enhancement process developed by Great River Energy refines or beneficiates lignite coal through a thermal drying and mechanical segregation process. Drying utilizes residual or waste heat to raise the heating value of the coal per pound.
