Whether we’re upgrading infrastructure to serve customers or restoring power after a monsoon, we’re always working to keep the lights on and maintain our reliability. Learn all the ways we keep the lights on.

Restoration and outages

Many factors can affect power restoration times if there is an outage. We provide our best estimate based on similar situations and will work to quickly and safely get the lights back on.

You can easily stay informed on any outages in your area with our Outage Center, where you can sign up for outage alerts, report an outage or view the outage map.

Summer and winter preparation

Arizona has a wide range of weather from frozen winters in the northern areas of the state to high heat in the deserts, and we work year-round to be ready for whatever Mother Nature has to offer.

We conduct line and equipment inspections throughout the year to prepare for heat and storms. And if an outage occurs, we will be ready to get the lights back on quickly and safely.

Maintaining and upgrading our grid

Our energy grid - the poles, wires, substations and other equipment that allow us to deliver power to our customers - spans more than 34,000 square miles through 11 of Arizona’s 15 counties. We continually upgrade and expand this equipment to better serve our customers.

Here are a few of our focus areas when investing in grid upgrades and maintenance:
  • System Improvements: Adding new technology/equipment to make our grid more resilient and flexible and integrating technology that allows us to remotely and more quickly detect and restore outages remotely and more quickly.
  • System Maintenance: Monitoring the health of our system for indications of failure, and proactively replacing equipment before it fails.
  • System Growth: Building new facilities and adding infrastructure to serve new customers.

Managing vegetation around electricity

Your safety and the safety of those in your community is of the utmost importance. We want to work with you to make sure that the trees, shrubs and other greenery on your property are safe around any of the electrical equipment on or near your property.
