Advanced Meter FAQs
When will the meters be installed and do I need to be home?
Most of the installations will occur Monday through Friday 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.
If you are both an electric and natural gas NorthWestern Energy customer, the new electric meter will be installed first and the new gas module will be installed during a follow-up visit to your home or business within the following eight weeks.
Who will change my meter?
NorthWestern Energy contracted with Tru-Check to install the new digital meters, the same company that installed the first generation, one-way communication digital meters in 1998 that are in use today.
Tru-Check technicians will wear apparel with the Tru-Check logo and will carry a NorthWestern Energy contractor identification badge.
What happens to the meter on my home or business now?
Will I have to pay for the meter?
What if I don’t want an upgraded meter?
NorthWestern Energy is bypassing customers who do not want an upgraded meter. NorthWestern Energy Montana customers will have the right to opt-out of the use of advanced metering devices and may be required to pay a tariff charge, once the tariff is approved by the Montana Public Service Commission. The Montana PSC's schedule to determine NorthWestern Energy's application for the opt-out tariff is available HERE.
For more information, call NorthWestern Energy at 1-800-486-4280 or the Montana Public Service Commission at 1-800-646-6150.
Montana law allows customers to opt-out of the use of advanced metering devices according to terms and conditions set by the Montana Public Service Commission. No utility company can require the use of an advance metering device. If you have questions about your opt-out rights, please contact the Montana Public Service Commission at 1-800-646-6150.
Are radio frequency (RF) emissions coming from the meters and modules?
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 the one-way communication meters in use now and the two-way communication meters that are being installed for this technology upgrade are both approved by the FCC. Radio frequency emissions are also produced by common household devices such as microwaves, baby monitors and TVs.

Is customer information protected?
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.
