An Arizona electric utility is installing a series of wildland fire-detection cameras in a remote area of its transmission line corridor to allow it to identify sparked wildland fires and also monitor transmission equipment that was damaged by wind or storms.
Salt River Project (SRP), a community-based, not-for-profit public power utility and the largest electricity provider in the greater Phoenix metropolitan area, serving approximately 1.1 million customers, also provides water to about half of the Valley’s residents, delivering more than 244 billion gallons of water (750,000 acre-feet) each year, and manages a 13,000-square-mile watershed that includes an extensive system of reservoirs, wells, canals, and irrigation laterals.
SRP is piloting a Smoke Detector Pilot Project that will act as a camera and smoke detector early-warning system for wildland fires that occur near the utility’s transmission line towers in the Tonto and Apache-Sitgreaves National Forests. The project, which is expected have an impact on wildland fire preparedness and protecting a portion of the Valley’s watershed, is the first of its kind in Arizona.
The smoke detectors and cameras, which have been used in CA and Europe, are SmokeD models, made by a manufacturer in Warsaw, Poland, says Floyd Hardin, SRP’s fire management officer. Besides detecting the initiation of wildland fires, the SmokeD units will capture physical changes on the utility’s 500-kilovolt (kV), transmission towers that transmit energy to the Valley from power plants located in eastern AZ.
A dozen of the SmokeD cameras will be installed along sections of transmission lines in the Tonto and Apache-Sitgreaves National Forests.
About 120 miles of SRP’s high-voltage power lines are located on U.S Forest Service land located in the northeastern part of the state. SRP is setting up two test areas with 12 cameras to capture images of a portion of the 500-kV transmission towers every 10 minutes, Hardin points out. The solar-powered infrared cameras can work at night and capture images up to 10 miles out with a 360-degree view.
Using Artificial Intelligence (AI), the cameras can learn their surrounding environment, report changes, and provide alerts when identifying smoke from wildland fires or changes to structures, Hardin says. The cameras can also alert SRP to issues such as downed lines, downed towers, or damaged equipment.
