In Latvia, smart meter manufacturer ADD GRUP has signed an agreement with Baltic electricity services company Latvenergo and installation company ELKO to deploy an advanced metering infrastructure system (AMI) to cover up to 100,000 customers.
ADD GRUP, which has already deployed 420,000 meters for Energa Operator in Poland, will supply Latvenergo with an end-to-end solution covering smart meters, data concentrators and head-end software.
Latvenergo has selected ADD GRUP’s ADDAX meters and data concentrators, which are based on a universal hardware and communication platform allowing switching between different PLC technologies, like PRIME and G3, the same technology used in Energa Operator’s rollout.
The Latvian energy company has also mirrored Energa Operator’s decision to choose USB as an essential requirement for smart meters, which subsequently became a standard issued by Energy Regulator in Poland.
It provides connectivity to 2G/3G/4G modems for WAN to ensure communication in areas problematic for PLC, as well as to wireless M-Bus modules that will potentially be used to integrate meters of other resources into head-end software.
ADD GRUP has said it expects the AMI to achieve the same results as in the Polish deployment, where the collection rate for 15-minute interval data was more than 99 per cent.
