3 A2A group A2A spa is the multiutilityborn on 1st January 2008 as a result of the merger between AEM SpA Milan and ASM SpABrescia with the contribution of Amsaand Ecodeco, the two companies acquired by the Group. At present, A2A group is: national leaderin the environmental sector, given that it treats more than 3 million tons of waste in 1 st placebetween the former Italian public utilities companies in terms of clients and turnover in 1 st placein Italy in the district heating sector in 2 nd place in Italy in terms of installed electric capacity and volumes of sales in 3 rd place in Italy in terms of gas sold

4 A2A Reti Elettriche(ARL) ARL isthe DSO company, bornsin 2009 from AEM Electricity & ASM Electricity Muncipality 50 Customer Energy distributed 1.1 ML GWh

14 DSO's needs

15 DSO's needs

16 DSO's needs Vertical and horizontalintegration, decentralizatefunctionalities, regulatory framework separation of competence, standard protocols compliance

17 DSO's needs Clustering approach Functions classes and first TLC requirements Code Function class Value signal Transfer time Reliability level APF Active Protection Functions (HV/MV-MV/LV level) Block & trip signal <=20 ms % CMD Command, Control & regulations O/C command Load shedding <=2s 99.99% Peak shaving MON Monitoring and Analysis Analogical & Digital TVPP <=2s 99.99% AMS Advanced Meter & Supply management functions (commercial functionality) Energy meas, Supply mgmt Commands, Alarms signals <=5m <=10s 96-> 99% IEM End to end info. exchange and management Energy meas. CVPP/Load Other signals <=5m <= 5s 95 ->99.9%

18 Agenda A2A reality Project overview Integris Vision DSO's needs toward Smart Grid Grid structure and Key aspects focused areas

19 Grid key aspects A2A gridin Brescia area is representative of the mix of issues to address The area includes urban, rural, mountainous territories

20 Grid key aspects Structure and complexity of the distribution grid HV grid small number's full remotely controlled PRIMARY SUBSTATION 20 HV GRID [km] 300

21 Grid key aspects Structure and complexity of the distribution grid MV grid extension, density of customer 1 Primary Station feeds about 150 secondary substations Secondary Substation 3192 MV GRID [km] 1775 SS not-controlled 2420 SS controlled 772

22 Grid key aspects Structure and complexity in urban area In urban area grid infrastructure is today underground great part of SSs in urban areas (down town), are underground SS street level 2098 SS underground 601 MV GRID [km] 1755

23 Grid key aspects Structure and complexity in rural area Mix in rural areas predominantly pole-mounted substations, low density of customer for SS SS street level 2098 SS underground 601 SS on poles 493 MV GRID [km] 1755

24 Grid communication aspects Communication and data flow complexity

25 Grid key aspects Importance and complexity of the LV grid Every SS govern a separate LV grid (600->2 customer) 2500 SS (LV grid dived in 9080 LV feeders) for LV supply points very extented and important asset for opex and capex optimization SS not-controlled 2420 SS controlled 772 LV GRID [km] 8000 MV GRID [km] 1755

26 Grid key aspects

27 Agenda A2A reality Project overview Integris Vision DSO's needs toward Smart Grid Grid structure and Key aspects focused areas

28 focused areas Key aspects to address for TLC complexity SS underground SS on poles SS between the buildings SS between the mountains There is no single communication technology up to the job and cost effective GSM/GPRS only Fiber Optic only Wi-Fi only Broadband Power Line Low performance Too expensive Not suited for underground stations Not suited for very long cables need an hybrid communication system centralized model is not suitable

29 focused areas Key aspects to address for new functions SS in 50% of the time in reverse power flow (DG) Great penetration of GD at LV level LV grid precious ASSET Millions of measuring points to govern the LV grid operations and develops, we have to measure each POD, and run calculation How this ispossiblein a cost effective way? Distribute intelligence in every SS Use standards protocol (61850) and GW to DLSM meters concentrator Use smart meters (2 nd generation) for grid needs
