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.

Sioux Falls, S.D./Butte, Mont. – March 31, 2026 – NorthWestern Corporation, a regulated energy service company operating in Montana and a subsidiary of NorthWestern Energy Group, Inc., doing business as NorthWestern Energy (Nasdaq: NWE), filed an application with the Montana Public Service Commission requesting approval of a Large New Load Tariff rule to establish requirements and contract terms for providing electric service to bundled customers with new or expanded loads of 5 megawatts or greater, including data centers and other energy‑intensive operations.
The filing establishes a framework governing agreements between NorthWestern Energy and large new load customers and is intended to address the costs and operational considerations associated with serving those loads while protecting existing customers from cost shifting and other adverse impacts.
“Our responsibility is to serve new opportunities in a way that protects our existing customers and strengthens Montana’s energy future,” said NorthWestern Energy President and CEO Brian Bird. “This proposal reflects Montana values—fairness, accountability, and thoughtful growth—while positioning our state to compete for high‑quality economic development.”
NorthWestern Energy’s filing of this proposed tariff provides a forum for the Montana Public Service Commission and interested stakeholders to evaluate NorthWestern Energy’s plans to serve new large loads.
“Given the strong interest from both the Montana Public Service Commission and the public, we believe it is important to bring this issue forward now, instead of waiting until a contract with a large new load customer is in place,” Bird said. “Filing this tariff now supports constructive dialogue as we all work together toward a solution that serves Montana best.”
NorthWestern Energy continues to negotiate agreements with prospective large new load customers.
Customer Protections and Contract Requirements
The Large New Load Tariff includes specific requirements that must be incorporated into electric service agreements with large new load customers. These provisions include:
These provisions are intended to ensure that customers taking large new loads are responsible for the costs associated with serving those loads and that existing customers do not subsidize these large new load customers.
Studies, Agreements, and Montana Public Service Commission Oversight
Under the proposed tariff, prospective large new load customers first enter into a development agreement and fund studies to evaluate system impacts, infrastructure needs, and service feasibility. The results of those studies are incorporated into an electric service agreement, which includes required customer protections under the tariff.
NorthWestern Energy’s Large New Load Tariff establishes a consistent, Montana Public Service Commission-approved framework for onboarding new or expanded customers with an expected load of 5 megawatts or more, including a standardized study process and required Electric Service Agreement protections.
For the largest commitments, 50 megawatts or greater, NorthWestern Energy must file the executed Electric Service Agreement with the Montana Public Service Commission for review and approval before service begins. For customers with loads between 5 and 49 megawatts, the tariff’s standardized process and mandatory protections apply, but individual agreements do not require case-specific Montana Public Service Commission approval filings.
Public Review Process
The Montana Public Service Commission is the authority for reviewing and approving electric tariffs in the state. NorthWestern Energy’s application initiates a public regulatory proceeding that will include opportunities for review and public comment consistent with Montana Public Service Commission procedures. NorthWestern Energy’s priority throughout the process is to provide safe, reliable energy service to customers at affordable rates.
“We look forward to working collaboratively with commissioners, stakeholders, and our customers,” Bird said. “Our goal is a solution that protects Montanans, supports reliable electric service, strengthens Montana’s energy infrastructure, drives responsible economic growth, and is right for Montana’s unique situation.”
