BISMARCK, N.D. - Montana Dakota Utilities plans to close three coal fired electric generation units at two locations in North Dakota and Montana.
MDU says the units will close within the next two to three years and a new simple cycle natural gas combustion turbine will be built.
The decision was made as part of the companies resource plan.
The unit at the Lewis and Clark Station in Sidney, Mont., is expected to close near the end of 2020. The two units at the Heskett Station in Mandan, N.D., are expected to close at the end of 2021.
MDU says the total cost of building and operating a new simple-cycle combustion turbine is expected to be about half the total cost of continuing to run both stations.
Montana-Dakota employs 77 people between the two coal stations and only 10 employees will be needed to operate the new units.
MDU says it will offer training to employees who wish to fill open positions in other areas of the company.
