Maintaining the Grid

From providing energy for customers’ homes and businesses to responding when severe weather hits, maintaining reliable service is an integral part of what we do every day. In fact, we keep the lights on 99.96% of the time! We have a team of operators who are monitoring the grid 24/7, ensuring you have the energy you need every hour of every day when you flip that switch.

We Maintain, Inspect and Improve the Grid

We have a proactive plan of scheduled maintenance and inspections to help ensure safe, reliable service.

  • We are currently replacing power lines buried underground over 40 years ago with more modern, reliable lines. When this project is finished, we’ll have upgraded 7,000,000 feet of power lines! Learn more about our Underground Cable Replacement Project.
  • We build and maintain thousands of miles of power lines and hundreds of substations to ensure safe and reliable service. View a map of our latest major projects, like new transmission lines and substations, that help keep our system reliable.
  • To proactively prevent power loss from downed poles or wires from fires, our crews clear brush within a 20-foot radius of power poles in the Idaho desert. This creates a defensible space around power poles, reducing the number of poles that are lost during wildfires. That means better reliability for customers. Watch this video to learn more.

To protect our crews during maintenance work, we sometimes need to turn off power as a safety precaution. If we need to turn off power in your area for scheduled maintenance work, we’ll let you know in advance (typically at least two days’ notice) and update you if anything changes. A scheduled maintenance outage may not begin or end at the precise times indicated in your notice. Power may also be turned on and off more than once during the outage period.

We Monitor and Balance the Grid

Energy is a real-time business. When you flip the switch, the energy that comes into your home or office was generated just a fraction of a second ago at a power plant miles away. Our job is to keep that system of supply and demand in balance around the clock.

See how we balance the grid to provide reliable, affordable, clean energy when and where you need it.

We Meet or Exceed Reliability Standards

Our equipment is built to meet or exceed industry standards and withstand the snow, ice and wind that Idaho winters often bring. To help prevent power problems and outages, we follow standards set by the North American Electric Reliability Corporation and Western Electricity Coordinating Council.
