Threemile Canyon Farms

Threemile Canyon Farms, a large dairy farm located outside of Boardman, Oregon, is home to the largest cow manure digester in the western United States. The facility started with a small digester demonstration project in 2009 and added a new, larger digester in late 2012 which fuels a 4.8-megawatt electric generation facility. The second digester produces an additional 37,000 megawatt-hours of renewable power each year from the waste of an estimated 40,000 dairy cows.
