Project Description/Scope/Purpose
This project funds the replacement costs of the battery backup systems that have been installed on all the traffic signals in the City. Batteries have between five to six years of life expectancy. The City currently operates and maintains 138 traffic signals.
Batteries are replaced over a seven-year period concurrent with the installation of the original devices. Inverters and wiring, separate from batteries, typically last 15-20 years. Replacement of the inverters and wiring is scheduled to start in FY 2024/25 concurrent with installation of original devices.
Project Evaluation and Analysis
Installation of uninterruptible power supplies at traffic signals reduces congestion and improves safety for all users of the City’s roadway system during planned and unplanned power outages. If Pacific Gas and Electric (PG&E) power is lost, the traffic signals will continue to function in a normal fashion and motorists will not be required to treat dark signalized intersections as All- Way Stop controlled intersections.
Fiscal Impact
About 20 inverters and wiring of UPS systems and batteries for approximately 25 locations are expected to be replaced every year; however, depending on current market pricing and adjusted for inflation, less than 20 inverters and wiring for UPS systems and batteries for approximately 25 locations could be replaced.
