Oncor has deployed meters manufactured by Landis+Gyr. These meters are certified to an accuracy standard that is significantly higher than the certification requirements of traditional meters. Additionally, Oncor accuracy limits are more stringent than industry standards.
Comprehensive quality control initiatives include:
- The meter manufacturer tests all meters and ensures compliance with all standards prior to shipment.
- Oncor tests a statistically significant number of advanced meters prior to installation.
- Every year, Oncor tests in-service meters to ensure that meters are continuing to maintain their accuracy throughout their service life
- Oncor monitors meter signals 24/7 to ensure proper operations and employs problem resolution when necessary.
In Texas, independent third party testing indicated that the advanced meters accurately measured and recorded electricity usage.
