Cloud Peak Energy Inc. · Gillette, WY United States ·(NYSE: CLD)

Apparently, there's also coal in them there hills. Cloud Peak Energy operates three wholly owned coal mines located in the Powder River Basin of Montana and Wyoming. Its coal is sold primarily to utilities and accounts for 6% of the electricity generated in the US. The company, a subsidiary of Rio Tinto, produces about 100 million tons of coal annually and controls 1 billion tons in proved and probable reserves. It was formed in 1993 as Kennecott Coal and changed its name to Rio Tinto Energy America (RTEA) in 2006 to align itself more closely with its parent in the eyes of the public. Two years later Rio Tinto formed Cloud Peak Energy to hold most of RTEA's operations in preparation for divestment. To read the full description, subscribe now.
