North Dakota operates 35 E85 stations for its population of 770,000—modest station counts but exceptional ethanol production credentials. The state produces vastly more ethanol than it consumes, exporting approximately 90% of output.
North Dakota hosts 6 operating ethanol plants with combined capacity exceeding 550 million gallons annually—a 50% increase over the past decade. The state is a national leader in carbon capture technology at ethanol facilities.
Tharaldson Ethanol in Casselton leads at 170-175 million gallons per year using 60 million bushels of corn. Other major facilities include Guardian Energy Hankinson (154 million gallons), Dakota Spirit AgEnergy in Spiritwood, Blue Flint Ethanol in Underwood, and Red Trail Energy in Richardton. Red River Biorefinery in Grand Forks uniquely produces ethanol from sugar beet tailings and potato waste.
The Biofuels PACE Loan Program provides up to $500,000 in interest buy-downs for ethanol facilities. Quarterly Ethanol Production Incentive payments support producers when prices drop. Bank of North Dakota guarantees up to $400,000 for biomass fuel facilities.
Casey's General Stores serves as the primary E85 retailer, operating blender pumps throughout the state. Coverage clusters along the I-94 corridor connecting Fargo and Bismarck. Eastern North Dakota benefits from proximity to Minnesota's strong E85 network.
Northwestern North Dakota remains largely underserved. Western portions beyond Bismarck, including the Bakken oil region, have sparse E85 coverage.
North Dakota enjoys lower overall fuel prices, with E85 typically 10-20% cheaper per gallon than regular gasoline.
Stick to the I-94 and I-29 corridors for reliable E85. If heading west toward Montana (which has zero E85 stations), fill up in Bismarck. Minnesota offers excellent E85 backup to the east.
