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.
