Pacific Gas and Electric Company (PG&E) has announced it will replace some of Landis+Gyr’s electric SmartMeters because of a rare defect in the devices. Landis+Gyr reports the error affects fewer than 1,600 of the two million meters it supplied to PG&E. The utility will replace the meters at no cost to customers and issue full refunds to customers who received inaccurate bills.
A new study released today (080410) confirms that the OpenWay Itron smart meters deployed in Texas are much more accurate than the analog meters they replaced. The report, Evaluation of Advanced Metering System (AMS) Deployment in Texas, was conducted by Navigant Consulting LLC, at the request of the Texas Public Utility Commission. Of the thousands of meters examined during the test, all were found to be accurate by American National Standards Institute (ANSI) standards.
