Wyoming's Governor signed into law a bill that pushes public utilities to make a "good faith effort" to sell coal-fired electric generation facilities slated for retirement. It requires power companies that want to decommission a coal-fired plant to seek a buyer first. If an entity purchases the plant, the bill requires the utility that sold the plant to buy back the power, even if a cheaper source is available.

Wyoming utility companies have reported that early retirement of some coal-fired units could save money. The investment firm Lazard Ltd. has estimated that wind power is a lower cost new generation power source compared to coal. Wyoming is the largest coal producer in the United States, and state legislators are concerned about the impact closing coal-fired plants will have on jobs and the economy of the state.
