How can we help you?

Why are you contacting us today?*

If this is an electrical emergency, please call us immediately at 800-638-3278.

If your power should go out, find out if neighboring homes still have electric service. If they still have power, check your fuse box or circuit breaker panel. If a fuse is blown, or a circuit breaker is open, turn off the lights and appliances on the circuit. This will help prevent damage to your appliances and your electrical system as well. Then replace the fuse with the correct amperage for the circuit or turn on the breaker. If a fuse continues to blow or the breaker continues to open, call an electrician to find and repair the problem.

When the electric outage is not confined to your home, disconnect or turn off as many electrical appliances and lights as possible. This will help protect your equipment and reduce the initial demand for electricity when the power is reconnected. Leave one light switch to the “on” position so you can tell when power is restored. Then you can reconnect appliances one at a time.Call Montana-Dakota Utilities to report any outage not confined to your home unless you know a neighbor has already reported it. Call us at 800-638-3278.

If you smell natural gas or think you have a gas leak:

Get everyone out of the building immediately
DO NOT use the telephone, a flashlight, or any electrical switches
Once you are safely outside, call Montana-Dakota Utilities at 800-638-3278 from your cell phone or a neighbor's phone
