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

The company says Gridstream PLX offers an 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. The technology is based on a two-way communications network that allows commands to be sent as data is received.

Key features of Gridstream PLX include 15-minute-interval kilowatt-hour 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; and minimum and maximum voltage reads with time of occurrence by phase.
