FAIRMONT, MINN. – Farmer Dwayne Ehlert remembers the moment last August when he delivered a truckload of corn to an ethanol plant here and sold it for a record $8.16 a bushel.
"I knew it was good for me, and I knew it wasn't good for anyone else," said Ehlert, 70, who has been farming for five decades on the outskirts of this southern Minnesota city.
High prices for corn, from which ethanol is made, have hammered the ethanol industry. A month after Ehlert made his profitable delivery, the Fairmont plant halted production, one of 20 U.S. ethanol producers to do so over the last year.
In Minnesota, the nation's fifth-largest ethanol-producing state with 21 plants, three ethanol facilities went idle. Minnesota corn farmers like Ehlert, whose crops survived the drought that wrecked other states' harvests, kept hauling corn to ethanol plants and fetching some of the highest prices ever.
For the first time in 16 years, U.S. ethanol production declined in 2012, in tandem with a drop in gasoline demand thanks partly to more fuel-efficient vehicles. Ethanol makers got caught between the high cost of corn and ethanol prices that sometimes sank too low.
"No matter who you were, you were working hard to get through the year," said Greg Ridderbusch, president of Blue Flint Ethanol, an Underwood, N.D., ethanol plant owned by Great River Energy, the wholesale power cooperative based in Maple Grove.
As Minnesota corn farmers prepare to plant a record-size crop this season, the outlook for the ethanol industry could turn on the next corn harvest — and whether it brings lower prices.
"All they want to do is get to a new crop," said John Christianson, principal in a Willmar, Minn., accounting firm that tracks ethanol plants.
