In addition to measuring the amount of electricity being used in a home, smart meters measure when the energy was consumed, thus enabling utilities to potentially offer additional pricing options based on the time of day. Having this additional usage information and pricing options could help interested customers better manage their energy consumption.
Pennsylvania's Act 129 requires Electric Distribution Companies with at least 100,000 customers to file a smart meter technology procurement and installation plan with the Pennsylvania Public Utility Commission. Act 129 also provides a 30-month grace period before installation would begin, allowing utilities to further study smart meter technology, as well as customer interest in the program.
