Natural gas dials represent the amount of natural gas measured in volumes of hundreds of cubic feet (ccf).
A gas meter is driven by the force of the moving gas in the pipe, and also turns faster as the flow increases. Each time the dial with the lower value makes one complete revolution, the pointer on the next higher value dial moves ahead one digit.
In the example below, the reading is: 6 2 3 8
The basic unit of measure of electric power is the watt. One thousand watts is called a kilowatt.
When you use one thousand watts of power in one hour, you have used one kilowatt (kWh).
We bill you by the kWh. Your electric meter is a digital meter that has an electronic display that displays the current reading, like a digital clock.
When reading an electric meter, write down the numbers as shown on the meter.
In the example below, the reading is: 0 0 2 1 0 8

NorthWestern Energy began installation in Montana in 2021. Here is a list of approximate dates for the Montana Meter Upgrade project by area:
A NorthWestern Energy employee will install your new meter or module.
Most of the installations will occur during business hours, though there will be cases when evening or weekend installations may be necessary. Customers don't need to be home.
A door hanger will let residents know their upgrade was successful. If the technician cannot perform the upgrade, a door hanger will be left with instructions to call to make an appointment.
Yes. The Federal Communications Commission (FCC) regulates the safety limits for all RF emissions, and smart meter and module emissions make up a small portion of the limit. The RF emissions of old one-way communication meters and the new two-way communication meters are both approved by the FCC. Radio frequency emissions are also produced by common household devices such as microwaves, baby monitors and TVs.
Yes. Customer privacy and security are NorthWestern Energy priorities. The company’s strict security standards have contributed to protecting the energy grid and customer privacy for years. The meters do not collect, store or transmit any personally identifiable information.
The meters measure total energy and cannot differentiate energy usage by appliance or anything else within a home or business. The transmitted energy use information is encrypted.Customers who want to keep their existing meters can call NorthWestern at 888-467-2669 or email NorthWesternEnergyMeters@northwestern.com to be added to the bypass list. Customers who previously requested an opt out do not need to contact NorthWestern again to be bypassed and keep their meters.
NorthWestern will be reaching out to customers who received an advanced meter despite their request to opt out. For those who still wish to opt-out, NorthWestern will ensure that the advanced meter is removed and replaced with a meter similar to the one that was there before. Customers will not be charged for this service.
Customers who have questions about the advanced meter opt-out program can contact NorthWestern at 888-467-2669
or the Montana Public Service Commission at 1-800-646-6150 or pschelp@mt.gov.
