Landis+Gyr Announces Next-Generation PLC Network

Landis+Gyr has launched Gridstream PLX, the next generation of power line carrier (PLC) technology for advanced metering networks.

Gridstream PLX offers a large increase in data capacity over legacy PLC systems, delivering 15-minute interval data from each meter on the network and enabling utilities to view that data within 30 minutes. A true two-way communications network, PLX allows commands to be sent as data is received. The system's increased capacity improves the performance of over-the-wire firmware upgrades and data encryption for enhanced security.

Key features of Gridstream PLX include:

  • 15-minute interval kWh or voltage data delivered continuously from every meter
  • 45 days of interval data storage at the meter
  • Remote updating of module firmware
  • Four adjustable time-of-use rates within multiple schedules and holiday rates
  • Minimum and maximum voltage reads with time of occurrence by phase

PLX builds on Landis+Gyr's previous PLC network offerings, and maintains trademark features such as continuous and simultaneous communication with every endpoint. This communication method provides the advantage of unsolicited outage notifications, distribution line monitoring and time-synched "snapshots" of demand or voltage levels across the entire system.

Gridstream is Landis+Gyr's smart grid platform that delivers advanced metering, grid automation and consumer energy management capabilities to utilities worldwide. The solution integrates a number of communication technologies – including RF mesh, PLC and cellular – under a single head-end operating platform to give utilities the best technology fit and value for managing and controlling energy distribution systems.

Landis+Gyr is receiving orders for PLX systems, with product scheduled to ship in February 2013. Utilities should contact their sales representative for more information.
