Our forestry department controls trees, shrubs and brush growing around our facilities and equipment, including more than 20,000 miles of overhead power lines in Arizona. It’s part of our commitment to supply safe, reliable electric service.
plant power line friendly trees

​Trees are important to urban environments but they must coexist with overhead power lines. When it’s necessary to remove tall trees growing near power lines, we provide low-growing replacement trees whenever possible. 

Right now, we’re involved in an extensive multi-year tree replacement project in the Phoenix metropolitan area. We’re removing thousands of existing street trees, which normally require routine trimming, to provide safe clearances from overhead wires.


right tree, right place
​Planting the right tree in the right place provides shade, reduces energy costs, improves water quality and cleans the air. We sponsor programs that encourage planting the right tree in the right place, including power line-friendly trees.

To learn more about tree selection and tree planting, or to find a certified arborist visit the Arizona Community Tree Council or International Society of Arboriculture.
national recognition for a superior program

Our forestry department's high-quality standards have been recognized each year since 1997. The National Arbor Day Foundation’s “Tree Line USA Utility” award recognizes the administration of a superior program of professional tree care, providing annual worker training and implementing tree planting and public-education programs.

community relationships
​We provide a wide range of resources through our relationships with other green industry organizations including the Tree Research and Education Endowment Fund (TREE Fund). The TREE Fund works closely with the International Society of Arboriculture and Tree Care Industry Association and others to fund research and educational projects.
We also host Arbor Day celebrations at local elementary schools and city parks each year. We discuss the importance of trees in the environment and follow up with tree-planting ceremonies.
