Reliability & Power Quality

Utility worker

You can count on Rocky Mountain Power to deliver safe, reliable electricity and excellent customer service. We provide 99.98 percent service reliability to customers — and we are always working to improve.

Our efforts are focused on better, smarter, more efficient ways to bring you the service you expect and keep costs down.

Investing in our system

We’re making important investments in our system to ensure our customers and communities have the reliable electricity they need to prosper. A few of our projects include:


  • Upgrades will be complete in mid-2017 to our Treasureton Substation to strengthen the transmission system in the area.
  • Construction on our new substation in the Ririe area began in late 2016 to add capacity and improve reliability as the area grows. Completion is planned for mid-2017.


  • The addition of a second transformer at our Syracuse Substation – scheduled to be complete mid-2017 – will increase reliability for our customers in the Ogden area.
  • Rocky Mountain Power also completed 14 renewable energy projects in 2016. Approximately 700 megawatts of power from solar and wind resources will come into service by early 2017.


  • Rocky Mountain Power technicians have completed an upgrade at our Standpipe Substation. This multi-year project is working to improve system reliability for customers in south-central Wyoming.

Leveraging technology

Our engineers have developed and implemented state-of-the-art computer software and other system performance tools so we can:

  • Better investigate outages to prevent them from happening again.
  • Quickly identify and correct potential reliability problem areas.
  • Gain additional capacity from our existing transmission facilities, using them efficiently to get power where it’s needed.

We’ve also installed automatic vehicle locators in service trucks and snowcats to help us pinpoint the location of line crews and personnel. These devices enhance safety for company workers and save on fuel and costs.

What you can do

Due to a number of factors inside and outside your home, the voltage of your electric service can vary slightly. Most of the time you won't even notice these voltage variations, but modern sophisticated electronic equipment can be very sensitive to even small, split-second electricity fluctuations.
