Redfield Energy, LLC is an agricultural energy company specializing in the production and marketing of renewable fuels and value-added agricultural co-products. The company operates a dry mill corn processing facility that converts locally sourced feed corn into biofuels, animal feed ingredients, and industrial inputs. Redfield Energy offers a comprehensive portfolio of products and services, including fuel-grade ethanol; denatured and undenatured ethanol for motor fuel blending; distillers dried grains with solubles (DDGS) for livestock, dairy, and poultry nutrition; modified distillers grains with solubles (MDGS); crude distillers corn oil (DCO) for use as a primary feedstock in biodiesel and renewable diesel manufacturing as well as animal feed supplements; and grain origination, merchandising, drying, and storage services for regional growers. The company distributes its ethanol across regional and national wholesale fuel blending markets, while supplying high-protein feed co-products to regional feedlots, domestic livestock markets, and export handlers. Founded in 2005, Redfield Energy is headquartered in Redfield, South Dakota, where its manufacturing and grain receiving infrastructure is situated.
In recent operational and strategic developments, Redfield Energy has focused on significant decarbonization initiatives, plant efficiency upgrades, and capacity optimization. The company integrated Whitefox Technologies' ICE Plus membrane dehydration system to debottleneck distillation units, reduce natural gas consumption, and expand annual ethanol throughput toward approximately 72 million gallons. Furthermore, Redfield Energy commissioned a 65-acre, 11.5-megawatt direct current solar array adjacent to its production plant to supply approximately half of the facility's electric power demands, substantially reducing its operational carbon intensity score. The company also maintains a strategic alliance with Summit Carbon Solutions to capture, transport, and permanently sequester biogenic carbon dioxide emissions through a regional carbon capture and storage pipeline network, positioning the facility to qualify for federal Section 45Q tax credits and supply premium low-carbon fuels to regulated clean fuel markets.
