Electricity

We take pride in our record of reliable electric service. We never realize how much we depend on this silent servant until it is interrupted by a bad storm or equipment failure.

Montana-Dakota’s primary goal is to furnish reliable electric service at fair rates. But, our electric system is widespread and exposed to storms and other factors we cannot control. Although we employ the latest developments in equipment and operating methods to maintain adequate service, we cannot guarantee uninterrupted power. If you have computers and other sensitive equipment that require high grade, uninterrupted power, you should check with your computer equipment supplier for information on devices that will ensure the power quality you need.
