Bettencourt – Rock Creek Dairy Complex


With 60,000 cows and 13 facilities, Bettencourt Dairies is one of the largest dairy farm operations in Idaho and the largest cow manure treatment facility in the country. Beginning in 2012, Rock Creek Dairy, a Bettencourt operation with 9,000 cows, decided to manage their manure while simultaneously reducing odors and methane emissions, in addition to producing power for its buildings and the local grid.

Nearly 200,000 gallons of cow manure enter a Catepillar power system each day, which processes the biogas produced from the “wet”-style anaerobic digester. The facility produces enough electricity and heat generation to sell back to Idaho Power and New Energy One. They also make clean compost used on site as animal bedding.
