The company will be one of GNF’s main smart meter suppliers for the next two years and will also supply about 20,000 three-phase meters.

GNF representatives said ZIV has played a key role in the development of smart metering technology.

"Such knowledge together with a clear customer service and satisfaction policy has helped GNF to meet its objectives in the past. We trust ZIV will continue to support us during the ambitious deployment we will be pursuing in the coming years," GNF representatives added.

CG Automation said all Spanish firms will replace 70% of their analog meters by the end of 2016.

CG has expanded its smart grid portfolio coverage with a catalogue of distribution automation solutions that range from LV supervision to MV automation, including overhead MV line automation, compact secondary substations and micro-grid management.
