Working in Your Neighborhood
Our crews are working to improve resiliency and reliability
To help keep you informed when our work crews will be in your neighborhood, this web page includes information about some of our larger projects that may be occurring in your area.
TEP crews work year-round to strengthen our local energy grid by inspecting, repairing, and upgrading the lines, poles and other equipment throughout our service territory, which covers 1,155 square miles.
Over the last five years, we’ve invested approximately $1.2 billion to maintain and improve service while transitioning to a cleaner, more flexible and resilient energy portfolio.
These upgrades and improvements to about 5,100 miles of electrical lines strengthen our circuits – the local subsections of our grid – so that they are able to withstand extreme weather conditions, such as sweltering heat and violent storms, and support rooftop solar. This helps reduce power outages to ensure safe, reliable service now and for many years to come.
Our work projects range from preventive and routine maintenance and equipment upgrades to expanding our system to keep pace with the growing energy needs of the community.
The projects listed below let our customers know when and where TEP crews will be working on some larger projects in their area. Organized by general location, each project includes the nature of the work, its duration and any potential impacts to nearby residents.
