DENVER, COLORADO, U.S. — Operating margins for U.S. ethanol producers likely will remain weak for the remainder of 2019 under the weight of abundant production, according to a new report released July 2 by CoBank’s Knowledge Exchange Division.

Declining corn production this year also will squeeze margins and some ethanol plants will be forced to shut down or idle their production due to high corn prices or insufficient supplies, the report said.

CoBank said exports remain one area of optimism for ethanol producers, but that optimism is based on China’s plans to convert to E10 blend gasoline nationally by the end of 2020. In the meantime, domestic U.S. ethanol demand likely will be flat over the next two years.

“For margins to go up, supply will need to go down,” said Will Secor, economist, grain and farm supply, CoBank. “This will be a painful process for some higher-cost producers as they look to reduce production or exit the industry. Consolidation and a slow grind to higher margins will be themes in the coming years as the industry works through changes to absorb excess production capacity.”

Ethanol plants had expanded capacity after several years of positive margins. However, margins began sliding in the summer of 2018 and plants have struggled to remain profitable since then. With stocks expected to remain above 900 million gallons through the remainder of 2019, margins are expected remain low. 

One potential growth area is E15, as this fuel blend containing 15% ethanol can now be sold year-round. Some retailers will need to invest in additional infrastructure to support E15 sales and will have to weigh the costs of new pumps, tanks or other equipment against the potential profits from offering E15. 

Increased demand for ethanol due to E15 will be limited in the next three years as retailers make these investments and consumer acceptance builds. Longer term, the E15 fuel market will be able to provide stronger support to ethanol plant margins, CoBank said.

Persistent, low margins also will drive ethanol plants to diversify their revenue streams.

“The ethanol plant of today could turn into the corn bio-refinery of tomorrow,” Secor said. “One could expect co-product offerings to expand and investments in these co-product lines to increase. These co-product investments may include equipment to produce high-protein dried distiller grain with solubles, corn oil optimization, and new buyers for carbon dioxide.”
