Westmoreland Coal Co was incorporated as Delaware Corporation in 1910. The Company is an energy company with twelve surface coal mines in the U.S. and Canada. It is engaged in the production and sale of sub-bituminous coal and lignite to plants that generate electricity. The Company's operating segments are Coal - U.S., Coal - Canada, Coal - WMLP and Power. Coal segment concentrates on niche coal markets. The remaining coal production was sold on the open market, where the Company uses its logistical advantages to deliver its coal via truck and rail transportation. The remaining third of its production is lignite. The power segment is involved in the production of electricity. The Company owns two coal-fired power-generating units in Weldon, North Carolina with a total capacity of approximately 230 megawatts, which the Company refers to collectively as ROVA. It built ROVA, which commenced operations in 1994, as a Public Utility Regulatory Policies Act co-generation facility to supply Dominion North Carolina Power. ROVA is held by its wholly-owned subsidiary Westmoreland Partners. The Company's Kemmerer Mine is owned by its subsidiary Westmoreland Kemmerer, Inc., or Kemmerer. The Company's Absaloka Mine is owned by its wholly owned subsidiary Westmoreland Resources, Inc., or WRI. For its open market coal sales, the Company competes with many other suppliers of coal to provide fuel to power plants. The Company is subject to extensive regulation by federal, state, provincial and local authorities.
