Oregon's Largest Diary Producing RNG

A thousand miles separates Threemile Canyon Farms in Eastern Oregon, surrounded by high desert and sagebrush, from the crowded freeways of Los Angeles.

Though they might seem like distant strangers, the mega-dairy and the megalopolis are about to be connected by a most unexpected resource — cow manure.

Threemile Canyon Farms is Oregon’s largest dairy with 68,340 cattle, including 33,000 milking cows. In 2012, the farm built an anaerobic digester to capture methane emissions from all that manure. It has since used the gas to generate electricity, which it sells to the interstate utility PacifiCorp.
