When it comes to power outages, Texas electricity company Oncor needed to stay ahead of the customer by improving its ability to identify and repair problems fast. So in 2012 Oncor merged its Advanced Meter System (AMS) and Outage Management System (OMS) and integrated a melting pot of equipment and software, including a radio frequency network and meter data management system software from Landis+Gyr and Siemens. In March 2012 the company deployed the integrated AMS-OMS in two districts in the Dallas-Fort Worth area, and by May all advanced meters were fully integrated with the systems. The company says that 20% of outages are now resolved without a customer call. Since March 2012, Oncor has resolved 3,400 outages without customer interaction.
An essential feature in Oncor's system is that the meters are set to trigger anytime the voltage dips to 80% or less, allowing Oncor to take proactive steps to make repairs before a serious service disruption.
Oncor used IBM to integrate the AMS and OMS projects. The revamped system covers 3.2 million meters and 11,000 communication devices. Oncor plans to keep honing the AMS-OMS system and add data analytics this year.
