BILLINGS, Mont. (AP) — Montana-Dakota Utilities says it plans to install more electricity generation to its power plant in Sidney, Montana, to keep up with growing customer demands.
The 19-megawatt addition would be powered by natural gas and located within the company's Lewis and Clark coal plant.
It would be used to provide power to customers during times of peak demand and could reach full power within 10 minutes.
MDU spokesman Mark Hanson says construction costs are estimated at $40 million.
MDU provides electricity to 137,000 customers in Montana, Wyoming and the Dakotas. Hanson says the number of customers has been increasing by 4 percent to 6 percent annually, driven in part by the oil boom in the Bakken region of Montana and North Dakota.
