Smart Metering enable multi tariff contracts with near real time operations and changes
multi-tariff structure allows for flexible tariff management; e.i.:
6 different tariffs (with programmable maximum subscribed demands)
8 different daily periods [00.00 ÷ 24.00] with 15 min granularity
8 different type of days (from Monday to Sunday + Public Holidays)
3 different weekly structures
8 different annual periods
Activation of tariffs is made according to a real- time calendar

Remote Control and Automation System
In the remote controlled secondary substations the Remote Terminal Unit (UP) is able to open and close the switches according to a specific set of rules thanks to the indications coming from the fault detectors.
If you enable these rules, in case of a fault on the feeder, the switches are automatically opened and closed by the UP according to these rules so as to isolate the faulty feeder section.
With the help of the recloser installed at the MV line departure in the feeding Primary Substation, the healthy feeder sections located upstream the faulty ones are resupplied.
At the end of these sequence of operations the UP sends a spontaneous call to the control centre to alarm the operator on the events and to let him resupply the sections located downstream the faulty one.
It is important to highlight that this function is performed by the UPs on the feeder and by the recloser in the HV/MV substation without any intervention of control center; therefore it works also in case of faults in Central system or in telecommunication systems.
