Chasing the Elusive Benefits of Navajo Generating Station


In February 2017, the utilities with ownership of Navajo Generating Station in Arizona voted to cease operations of the coal-fired power plant. Two months later, Peabody Energy, operator of the mine that supplies fuel to Navajo, presented an analysis before the Arizona Corporation Commission demonstrating that Navajo is economically viable. On behalf of Sierra Club, Synapse examined this study, which was commissioned by Peabody and conducted by Navigant. Synapse found that Navigant relied on overstated market energy prices and understated Navajo's fuel prices, resulting in nearly $2 billion in errors.
