Meter and infrastructure notes
Killeen began replacing more than 55,000 mechanical meters with Advanced Metering Infrastructure in August 2021. AMI meters transmit usage to radio antennas and a water-tower base station, then to an encrypted cloud server used for billing and real-time customer monitoring. The rollout is phased at approximately 5,000 meters per year and is expected to reach full implementation around FY2033; the 2026 Phase 3 project ordered 4,544 residential and 288 larger commercial meters for installation from January through September 2026. Because legacy meters remain during the phased program, the City has not published a universal hourly-read schedule for every account.
