How do I read my meter?

Gas meter

Gas meter

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.

To read your meter: 

  • Be at eye level of the dials.
  • Mark the dials from left to right.
  • Take note of the direction of the arrows on the display – the pointer of adjacent dials turn in opposite directions to each other.
  • Draw the pointer on the dials as displayed on your gas meter.
  • When the pointer on the dial is between two numbers, record the lower number.
    • If the pointer is between 9 and 0, 9 is the lower number.
  • When the pointer is directly on the number, look at the dial to its right:
    • Has the dial on the right has passed 0, yes, use the number that the pointer is on.
    • The dial on the right has not passed "0," use the number less than what the pointer is on.

Example:

In the example above, the reading is: 6 2 3 8

Electric meter

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.



When submitting your meter reads, please be ready with your account number, your service address, your meter read(s) and the date you read your meter(s).

No. The electric meters and gas modules are purchased and owned by NorthWestern Energy. They are part of our infrastructure, similar to our power poles and transformers.

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.

NorthWestern Energy has a contract to recycle the electric meters and gas modules in use now when new meters and modules are installed.

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.

NorthWestern Energy Announces Missouri River Drawdown for Black Eagle Dam Spillway Project

Date: Jul 15, 2026

TYPE: News

Great Falls, Mont. – July 15, 2026 – NorthWestern Energy will temporarily draw down the Missouri River upstream of Black Eagle Dam from July 31 through mid-September to allow construction crews to complete critical upgrades as part of the Black Eagle Dam Spillway Project.

Work will take place on the upstream west-facing side of the dam and include installing new support structures and components of the spillway. These improvements are designed to enhance the overall integrity of the dam.

In addition to strengthening the structure, the upgrade will eliminate the need for NorthWestern Energy hydro crews to manually remove ice buildup during extreme winter conditions, improving both operational efficiency and worker safety.

River Access Impacts

For public safety during the project:

  • The Missouri River will be closed to public use and access from downstream of Broadwater Bay to Black Eagle Dam, including the kayak launch and dock at West Bank Park.
  • Broadwater Bay boat launch will remain open, as will the non-motorized take-out ramp at Oddfellows Park and the river upstream of Broadwater Bay.

Public Safety Reminder

The public is warned to stay out of the riverbed during the drawdown. Exposed areas contain:

  • Deep mud
  • Unstable ground
  • Rapidly changing water conditions
  • Unexpected hazards.

These hazards pose serious risks to both people and pets.

“We appreciate the public’s cooperation as we complete this important infrastructure project,” said NorthWestern Energy Manager Power Generation Jeremy Butcher. “These upgrades will help ensure the continued safety, reliability, and efficiency of hydroelectric operations at Black Eagle Dam.”

Work on the Black Eagle Dam Spillway Project will continue during the river draw down and temporary closures of the River’s Edge Trail near the dam north and south of the Missouri River will be required for the safety of the public and crews.
