OP-T2-18: Energy Metering

92% of the building space of Dominican has energy metering, however, 30% of the building space has building-level energy meter, which use the PG&E SmartMeter technology. The following buildings have the PG&E SmartMeter technology to meter all energy consumption: Edgehill Mansion, Edgehill Village, Conlan Recreation Center, Bertrand Hall, and the Facilities' building. All other buildings also have PG&E Meters but not SmartMeters. The SmartMeter™ electric meter records hourly meter reads and periodically transmits the reads via a dedicated radio frequency (RF) network back to PG&E. Each SmartMeter™ electric meter is equipped with a network radio, which transmits meter data to a electric network access point. The system uses RF mesh technology, which allows meters and other sensing devices to securely route data via nearby meters and relay devices, creating a "mesh" of network coverage. The system supports two-way communication between the meter and PG&E. The electric network access point collects meter data from nearby electric meters and periodically transfers this data to PG&E via a secure cellular network.

Due to the simpler data requirements of the gas system, the SmartMeter™ gas system supports only one-way communication from customers to PG&E. This module is outfitted with a radio frequency (RF) transmitter. The module records daily meter reads and then uses an RF signal to transmit the reads to a data collector unit in the vicinity. The data collector unit (DCU), in turn, collects meter reads from many meters and securely transmits the gas usage data over a secure wireless network back to PG&E. Source: PG&E Website
