Advanced electric meter installations rising in homes and businesses -- EIA

This report from the Energy Information Administration finds that electric meters with enhanced communication capabilities — an essential component of the smart grid — are becoming more prevalent. This offers the possibility that electric systems will become more reliable and efficient. In 2009, 39% of all U.S. electrical customers had advanced meters, up from 32% in 2008.

Advanced meters can use one-way communication (known as Automated Meter Reading, or AMR), which enables the utility to do remote meter reading, or two-way communication (Advanced Metering Infrastructure, or AMI). In 2009, 17% of advanced meters used two-way communication, up from 10% in 2008. These two-way meters are often referred to as "smart meters."
