Advanced Meter FAQs
What is the advanced meter project timeline in Montana?
NorthWestern Energy began installation in Montana in 2021. Here is a list of approximate dates for the Montana Meter Upgrade project by area:
- Missoula Division: completed August 2022
- Butte Division: completed June 2022
- Bozeman Division: completed May 2024

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.
Will I have to pay for the meter?
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 in about eight weeks.
What happens to the meter on my home or business now?
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.What if I don’t want an upgraded meter?
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.

NorthWestern Energy to participate in regional transmission projects
Date: Dec 12, 2024
TYPE: News
Butte, Mont./Sioux Falls, S.D. – Dec. 12, 2024 – NorthWestern Energy Group, Inc. d/b/a NorthWestern Energy (Nasdaq: NWE) is joining new high voltage transmission projects to expand Montana’s grid, meet the state’s increasing energy demand, enhance energy security and create opportunities to serve regional energy needs that will benefit all of our customers.
NorthWestern Energy joins North Plains Connector east-west transmission line
NorthWestern Energy has signed a nonbinding memorandum of understanding with North Plains Connector LLC, a wholly owned entity of Grid United, to own 10% (300 megawatts) of North Plains Connector, a 3,000-megawatt, 420-mile high-voltage direct current (HVDC) transmission line to be constructed with endpoints near Bismarck, North Dakota, and Colstrip, Montana. Grid United and ALLETE, Inc. are jointly developing North Plains Connector. Avista, Portland General Electric and Puget Sound Energy also have ownership MOUs with North Plains Connector. The project is entering the permitting phase and initiating regulatory filings with approvals targeted in 2026. Construction is expected to commence in 2028, aiming for the project to be operational by 2032.
Under the terms of the memorandum of understanding, Grid United will continue to fund the development of North Plains Connector. NorthWestern Energy would invest when project regulatory approvals and permits are in place.
“NorthWestern Energy’s Colstrip, Montana substation is strategically located and will serve as a critical endpoint for North Plains Connector, reinforcing Colstrip’s position as an essential energy hub,” said NorthWestern Energy President and CEO Brian Bird. “The North Plains Connector developer’s collaborative approach with Montana communities to address concerns and ensure the footprint reflects local priorities aligns with NorthWestern Energy’s commitment to our customers.”
North Plains Connector is the first interregional transmission line to create a major grid-to-grid connection across the three energy markets, the Midcontinent Independent System Operator (MISO), Southwest Power Pool (SPP), and Western Electricity Coordinating Council (WECC). The transmission line will create connection between NorthWestern Energy’s Montana and South Dakota service areas. The bidirectional transmission line will efficiently transport large amounts of power from areas with supply to areas in need and take advantage of diverse load and weather patterns.
“NorthWestern Energy is the only partner serving customers in both regions, which have diverse energy load demands and diverse energy generation resources,” said Bird.
“We are pleased to welcome NorthWestern Energy to North Plains Connector,” said Michael Skelly, CEO and co-founder of Grid United. “As Montana’s largest energy provider, NorthWestern Energy brings a breadth of experience and deep understanding of the region’s energy needs. Their support reinforces the importance of North Plains Connector as a meaningful solution for a strong and reliable electric grid.”
Earlier this year, NorthWestern Energy supported the Montana Department of Commerce as part of the North Plains Connector Interregional Innovation (NPCII) consortium in its successful application for a $700 million grant from the U.S. Department of Energy’s Grid Resilience and Innovation Partnership (GRIP) program. The NPCII includes an upgrade of the Colstrip Transmission System and while the majority of the grant is earmarked for the North Plains Connector, the grant also includes funding for a potential upgrade of the Colstrip Transmission System, which is jointly owned and operated by NorthWestern Energy.
Montana to the South Transmission Corridor
NorthWestern Energy and Grid United have also entered into a letter of intent to continue transmission development to further enhance the grid through the southwest corridor of Montana. Development to expand the southwest corridor of Montana through grid buildout would represent a significant step in enhancing connectivity between Montana and the broader Western energy market - bolstering grid reliability, allowing for critical import capability and enabling customers to access and benefit from emerging energy markets in the West.
