Data availability from Electronic Meters
 Voltage Quality
Period, Instantaneous Voltage value, VMIN and VMAX for each phase, number of samples in the allowed
range (230V+-10%), number of samples out of allowed range.
Electronics meters record a value every ten minutes: 1008 samples a week available.
 Voltage Outages
Period, onset time, duration of the interruption, affected phase, electric line involved
 Monthly consumption
Date, energy consumption value in a billing period on T1, T2 and T3

Data availability from Electronic Meters
 Load Profile
Graph and list of active and reactive power consumption and active power
feeding the grid (in case of active customers).
Electronic Meter stores Power average value every 15 minutes
 Power threshold
Percentage of contractual power available to the customer
 Daily consumption
Date and daily value of energy consumption

Load Profile
Active Customer Load Profile: set of
graphs available for each meter.
 A Load Profile Request returns to the operator a set
of graphs with the average active and reactive
power consumption profile and, in case of active
customers, the active power feeding the grid.
 Instead of a graphic representation it is also possible
to display the list of the average power
consumption values stored in the smart meter
every 15 minutes.
 It is possible to send a Load Profile request for a
single Smart Meter or a whole MT/bt
Transformer. In this case STAMI returns the load
profile of each Smart Meter, the Load profile, in a
unique curve, of the sum of al the smart meters
connected to the TR and the load profile of the
energy balance meter installed in the secondary
substation.
 It is possible draw the Load profile of each LV line
feed by the Transformer, to create any customized
group of meters of which the operator wants to
draw the Load Curve, to upload and display the Load
curve recorded by ALVIN, the portable energy
balance meter.

Rules and Obligations: Italian Timebased Tariff Regulation
Following the introduction of the Telegestore, the Italian Regulator established specific
metering rules depending on the characteristic of the customer:
 For HV, MV and LV customers with power installed >55 kW it is mandatory a meter
reading each hour.
 For LV customers with power installed <55 kW the reading is done per consumption
timeslots, F1, F2, F3, compliant with the timebased tariff regulation.
