Drive through Otter Tail County and you’ll eventually see it. The steam rising over the horizon just outside of town isn't just a local landmark; it's a massive economic engine. Green Plains Fergus Falls is one of those places people drive past every day without really grasping the scale of what's happening behind the gates. It’s not just a "factory." It’s a high-tech biorefinery that sits at the uncomfortable, fascinating intersection of American agriculture, global energy policy, and the fight over carbon emissions.
Honestly, the ethanol industry gets a bad rap sometimes. People think it’s just about corn. While corn is the literal fuel for the fire, what Green Plains is doing in Fergus Falls is significantly more complex than just turning kernels into liquid.
The Gritty Reality of Production
Most people think of ethanol as a simple additive. You see the "10% Ethanol" sticker at the pump and move on. But Green Plains Fergus Falls is pushing out roughly 55 million gallons of denatured fuel ethanol every single year. Think about that volume for a second. That is a staggering amount of liquid moving through a relatively small footprint in rural Minnesota.
It’s a 24/7 operation.
The facility doesn't just produce fuel, though. That’s a common misconception. For every bushel of corn that enters the plant, they’re squeezing out value in three distinct directions. First, you have the ethanol. Second, you have the distillers grains—the high-protein leftovers that local farmers scramble to buy for cattle feed. Third, they’re capturing corn oil.
It’s efficient. It has to be. In the commodity business, margins are razor-thin. If Green Plains Fergus Falls isn't squeezing every drop of value out of that corn, they're losing money. The plant uses a dry-mill process, which is basically a high-tech version of a distillery, grinding the corn into flour before fermenting it.

Why Fergus Falls?
Location is everything in the biorefining world. You can't just build these things anywhere. You need two things: an endless supply of corn and a way to move the finished product. Fergus Falls sits in a "sweet spot" of the Red River Valley’s periphery. The local grain elevators feed this beast constantly.
But there's also the rail access. Without the ability to ship millions of gallons via the Otter Tail Valley Railroad and its connections to Class I carriers, the plant would be a paperweight. Logistics are the invisible heartbeat of Green Plains Fergus Falls. If the trains stop, the world—or at least a significant chunk of the regional fuel supply—feels the pinch.
The Carbon Capture Elephant in the Room
We have to talk about the pipeline. It’s the most controversial topic in Minnesota’s energy sector right now. Green Plains, as a corporation, has been heavily involved in discussions regarding carbon capture and storage (CCS). The idea is simple on paper: capture the $CO_2$ emitted during fermentation, liquefy it, and send it underground via a pipeline to be stored in deep geological formations.
In practice? It’s a localized political firestorm.
Farmers who provide the corn for the plant are often the same people worried about eminent domain and the safety of CO2 pipelines crossing their land. Green Plains Fergus Falls finds itself in the middle of this tug-of-war. The company argues that carbon capture is the only way to make ethanol "green" enough to compete in a world moving toward electric vehicles and low-carbon fuel standards (LCFS) like those in California.

Without lower carbon intensity scores, the ethanol from Fergus Falls becomes less valuable. It’s a survival play. If they can’t lower their carbon footprint, they can’t sell into the premium markets. That’s the business reality that often gets lost in the environmental debate.
The Ultra-High Protein Pivot
Lately, there’s been a shift. Green Plains isn't just calling itself an ethanol company anymore. They’re rebranding as a "biorefinery." In Fergus Falls and their other locations, they’ve been installing MSC (Mechanized Separation Chromatography) technology.
What does that actually mean for a normal person?
Basically, they are extracting a much higher quality of protein from the corn—upwards of 50% protein content. This isn't just for cows anymore. This stuff is being eyed for the aquaculture (fish feed) and pet food industries. It turns a low-value byproduct into a high-value ingredient. It’s a brilliant hedge against the volatility of gasoline prices. If people stop driving internal combustion cars, Green Plains Fergus Falls can pivot toward being a massive protein factory.
Economic Impact: The Invisible Numbers
The plant employs roughly 40 to 50 people directly. That sounds small, right? But the multiplier effect in a town like Fergus Falls is massive. We’re talking about hundreds of truck drivers, maintenance contractors, and the literal thousands of farmers who have a guaranteed local buyer for their crop.

When the plant is running at full capacity, it supports the tax base for local schools and infrastructure. If Green Plains were to shutter the Fergus Falls location, the ripple effect would be felt in the local diners, the equipment dealerships, and the real estate market.
Common Misconceptions
People love to argue about ethanol. You've probably heard that it takes more energy to make ethanol than it yields. That’s actually outdated data. Modern facilities like Green Plains Fergus Falls have optimized their heat recovery systems so much that the energy balance is firmly positive.
Another one: "It ruins your engine."
Unless you're running a vintage 1960s tractor or a very specific small engine without proper seals, modern E10 or even E15 is perfectly fine. The sensors in your car are literally designed to adjust for it.
What’s Next for the Facility?
The future of the Fergus Falls plant is tied to two things: Sustainable Aviation Fuel (SAF) and the global protein shortage.
There is a massive push to turn ethanol into jet fuel. It’s a difficult chemical process, but it’s where the big money is going. If Green Plains can successfully transition their output to feed the airline industry, Fergus Falls stays relevant for another fifty years.
Actionable Insights for Locals and Investors
If you're living in the area or looking at the renewable energy sector, keep your eyes on these specific markers for the Fergus Falls plant:
- Quarterly Earnings Reports: Look specifically at the "Ag & Energy" margins. Green Plains Inc. (GPRE) is the parent company. Their ability to manage the "crush spread"—the difference between the cost of corn and the price of ethanol/byproducts—is the only number that truly matters.
- Local Corn Basis: If you're a producer, watch how the Fergus Falls plant's "basis" (the difference between local price and the Chicago Board of Trade price) shifts. It’s a direct indicator of their inventory needs.
- Legislative Shifts: Keep a close watch on the Minnesota State Legislature regarding carbon sequestration tax credits. The viability of the Fergus Falls plant’s long-term upgrades depends heavily on these subsidies.
- Protein Off-take Agreements: Watch for news about Green Plains signing deals with global feed companies. The more protein they sell, the less they rely on the whims of the local gas station prices.
Green Plains Fergus Falls isn't just a relic of the mid-2000s ethanol boom. It’s a pivoting, evolving piece of industrial machinery that is trying to figure out how to exist in a post-carbon economy. Whether you love ethanol or hate it, the facility is a masterclass in industrial adaptation. It survives because it refuses to just be one thing. It’s a fuel plant, a feed lot’s best friend, and a protein laboratory all at once.
