15 Uso: Aziendale Backup

16 Uso: Aziendale STAMI: Advanced Metering Interface Web Interface: main operations Information Viewing It makes possible to quickly access and download the results coming from user requests Data request Used to send data requests: it is possible to directly ask about a Meter, a Concentrator, a customized group of meters Status of transactions Used to display all the data requests and to check their status. ALVIN Management Used to upload and analyze data coming from portable energy balance meters (ALVIN)

17 Uso: Aziendale STAMI: Advanced Metering Interface Data availability from Electronic Meters Period, Instantaneous Voltage value, V MIN and V MAX 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 Quality  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

18 Uso: Aziendale STAMI: Advanced Metering Interface Data availability from Electronic Meters 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  Load Profile  Power threshold Percentage of contractual power available to the customer  Daily consumption Date and daily value of energy consumption

19 Uso: Aziendale STAMI: Advanced Metering Interface Viewing information menu: Power Threshold Defaulting Customer In case of a customer's phone call, Enel doesn’t need to send a technician on site to check if he is a bad payer. Defaulting Customer In case of a customer's phone call, Enel doesn’t need to send a technician on site to check if he is a bad payer.

20 Uso: Aziendale STAMI: Advanced Metering Interface Viewing information menù: Voltage Outages The fault can affect one or more phases

21 Uso: Aziendale STAMI: Advanced Metering Interface 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.

22 Uso: Aziendale STAMI: Advanced Metering Interface Load Profile Transformer Load Profile Measured Energy Balance Meter Aggregation of customers’ Load Profiles Sum of Energy measured by each Smart Meter Probable energy fraud Between 9.00 am to 6.00 pm the difference between the 2 curves is greater than the expected technical losses: a verification on field is needed Probable energy fraud Between 9.00 am to 6.00 pm the difference between the 2 curves is greater than the expected technical losses: a verification on field is needed

23 Uso: Aziendale Metering activities 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.
