North Dakota's Public Service Commission has scheduled hearings to settle arguments about which utility should provide power for two housing developments and an energy park.

Montana-Dakota Utilities Co. and Capital Electric Power Cooperative, both of which are based in Bismarck, are vying to sell electricity to two subdivisions on the northern outskirts of Bismarck.

A separate dispute between the two utilities recently ended up in the North Dakota Supreme Court, which ruled that Capital Electric, not MDU, had the right to sell power to a north Bismarck development called Boulder Ridge.

The PSC on Tuesday scheduled a Nov. 19 hearing to listen to arguments from MDU and Capital Electric about which one should serve the Promontory Point III subdivision, which is near the Missouri River in northwest Bismarck.

The commission scheduled a separate hearing on Nov. 20 on the Sonnet Heights development in north Bismarck, which is just west of U.S. Highway 83 and south of State Highway 1804.

Both hearings will begin at 9 a.m. in the commission's hearing room on the state Capitol's 12th floor.

Separately, the commission scheduled an Oct. 5 hearing on a dispute between Otter Tail Power Co., of Fergus Falls, Minn., and Northern Plains Electric Cooperative, which has headquarters offices in Carrington and Cando.

Northern Plains filed a late protest against Otter Tail's plans to provide permanent electric service to Spiritwood Energy Park, an ethanol factory and power plant being developed near Jamestown.

The $350 million project includes an expansion of a nearby Cargill malting barley plant.
