With Xcel Energy burning its last coal at a Colorado power plant, two major coal producers have lost a large customer. Xcel retired the unit its Valmont plant in Boulder, Colorado in March in response to a law requiring reductions in nitrogen oxide emissions. Most of the coal burned at the plant over the past five years came from Peabody Energy’s Foidel Creek mine, also known as Twentymile, and Arch Coal’s West Elk mine, which together sold the plant more than 2.6 million tons at a delivered cost of nearly $176.8 million from 2011 to 2016, according to data compiled by S&P Global Market Intelligence. Coal production across Colorado hit a four-decade low in 2016.
