Light S.A., a private utility providing electricity to the state of Rio de Janeiro, Brazil, has selected an advanced metering infrastructure (AMI) solution from Elster to help increase energy efficiency, conserve resources, empower consumers and enhance distribution to customers currently without electric service.
Between March and July 2011, Light plans to deploy 20,000 Elster Garnet units. Each secure Garnet unit contains configurations of 12 single-phase Elster residential electric Smart Meters, connection and disconnection relays, input and output terminals, a gateway GPRS modem and RF communications and networking capabilities.
The system will integrate with home area networks, providing customers with increased control and additional service options.
The Garnet unit has built-in security features and is housed in an all-weather stainless steel case that can be mounted high on an electric transformer pole or in a secure cabinet in locations such as apartment complexes.
