Westmoreland Rosebud Mining LLC

Westmoreland Rosebud Mining LLC

Westmoreland Rosebud Mining LLC – Montana

Rosebud is a 25,000-acre surface mine complex located in the northern Powder River Basin near Colstrip, Montana, and the Northern Cheyenne Indian Reservation. Rosebud is a large operation with three active pits and supplies almost all of its current production to the four-unit 2,100 megawatt Colstrip Power Station that is adjacent to the mine and was specifically designed to burn Rosebud coal.

Coal is sold to the Colstrip Station under two long-term contracts. Colstrip Station is one of the region’s most cost-efficient and cleanest power plants, which should help it maintain a base-load position on the electricity dispatch curve, and ensure continued strong demand for Rosebud coal. The Rosebud Mine produces approximately ten to thirteen million tons per year.
