Required density of meters on a cabin
05/11/2015 Source – Results from 19/06/2015
Density < 60% Density = 60% Density > 60%
Below 60% of smart meters installed on a cabin, the risk of non communication is rather high and stability of the solution can not be guaranteed.
With a minimum of 60% installed on a cabin, the risk of non communication is minimized but non zero.
With 100% of meters installed on a cabin, the risk of non communication is close to zero.
A high performance has been obtained with a density down to 60% of smart meters installed on a substation.

AMI – delays of detection
05/11/2015 Source – Results from 19/06/2015
The more meters installed, the faster they are detected by the AMI.

Extend G3PLC tests for smart public lighting (remote control relays, dimming,…)
Adapt the G3PLC solution for Belgian technical specificities (3 wires network) Investigate the use
of G3PLC on FCC band
Analyze furthermore the perturbance generated by PV inverter
Test the solution on a larger scale pilot and with the integration with ORES IT systems to prepare for rollout

Conclusions
05/11/2015
Our pilot demonstrated that the performance G3 PLC in the field is fulfilling the needs of ORES
G3PLC solution also proved to be robust in terms of noise perturbance as well as allowing for a progressive deployment.
G3PLC can be used for multiple DSO applications : Smart metering, Smart public lighting,…
G3PLC is interoperable and supported by large industry players ensuring long term vendor support
