San Francisco, CA, U.S.A. — (METERING.COM) — May 4, 2011 – Pacific Gas and Electric Company (PG&E) has discovered a “rare defect” that affects fewer than 1,600 smart meters supplied by Landis+Gyr and is to replace these and provide a refund affected customers.
The defect is that the meters will occasionally run fast when experiencing a narrow band of high temperatures, resulting in a miscalculation of energy bills. Through PG&E’s quality assurance program and the advanced diagnostics available through the SmartMeter™ technology, the problem was traced to less than 0.08 percent of the two million smart meters supplied by Landis+Gyr.
“We take this issue very seriously and will do the right thing for our customers,” said Greg Kiraly, vice president, SmartMeter™ Operations at PG&E. “We are committed to accurate metering and billing and will contact our affected customers immediately and issue full refunds.”
The utility will replace the meters at no cost to customers and the average refund will be about $40 per customer. In addition, PG&E will issue a $25 credit for customer inconvenience and offer a free in-home energy audit to affected customers.
PG&E says it will share the technical analysis of the meter issue with the California Public Utilities Commission (CPUC) for its review, and with the American National Standards Institute (ANSI), which approves the relevant testing standards for the metering industry.
If any additional meters malfunction, the diagnostic signals will flag the meters for immediate replacement.
