LINCOLN, Neb. (AP) — Lincoln Electric System and other owners of a coal-fired power plant in Wyoming have settled their rates dispute with BNSF Railway.

The settlement terms haven’t been released.

The dispute began more than 10 years ago when the Missouri Basin Power Project, which owns the plant, and the coal supplier filed a complaint with the federal Surface Transportation Board, saying the railroad was gouging them on coal deliveries to the Laramie River Station. In 2009 the board awarded the project members $345 million in rate relief. BNSF appealed, and the dispute has since been argued before the board and in federal courts.

The plant produces power for about 2 million consumers in Colorado, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, South Dakota and Wyoming.
