Oncor's Advanced Metering System (AMS) involves installing up to 3.2 million smart meters across its service territory by 2012. The smart meters will automatically collect customer energy usage data at 15-minute intervals and transmit it through a wireless mesh network and backhaul system. This data is validated and used to provide timely energy consumption information to customers, retailers, and ERCOT to support energy conservation, pricing programs, outage detection, and other benefits.
