4 A fast growth in RES generation creates new challenges for the grid and system management Installed capacity ( ) [GW] 140 Reserve 80 GW Reserve 25 GW 80 Thermo Peak Load Hydro Thermo almost shut down PV Wind Geo 42% of Peak Load Source: AEEG, Italian TSO 4

5 As a consequence, creating a distorted price curve which disrupts old conventions DayAhead Market 01/05/2013 [MWh, Euro/MWh] PV Wind Geo Price Thermal Utilization of power plants (14:00 15:00): Geothermal Hydro Hydro (River) Photovoltaic Thermal Wind Production [MW] 620 5,611 1,753 7,713 10, Hydro Plant Utilization* 80.3% 44.9% 29.4% 44.3% 14.2% 6.8% RES accounted 60.1% of the generation Source: Terna, GME *compared to total installed capacity 5

7 Smart grid is a full ecosystem which includes multiple technologies across the value chain PowerCo B Home/Building Automation supports: Inhome display with realtime usage/pricing statistics Usage aware appliances Home automation A Smart Meter allows: Usage by time (load profile curve) Outages in realtime, remote disconnection, Detection of electricity fraud Automated billing and contract management, Gateway to Demand Side Management C Distributed generation Management of variable loads and generation Facilitates: Integration of renewables sources, energy storage and evehicles; Disconnection in case of network overload D Network automation Enables: Realtime reporting of status and outages Voltage control and power flow control, Fast fault detection on MV/LV network with evident improvement of OPerating EXpenses for DSOs and service quality for customers. E Data collection, processing, and backup office allows: Automated billing and disconnection of unpaid; Daily usage stats and time of use pricing 7

9 How to overcome the main barriers to the RES integration? The Active Networks paradigm An increasing amount of DG & RES into the network is forcing an evolution toward the Active Network Approach: «Fit & forget approach» Resolving all the issues at planning stage oversized network. This approach is ok only with low DER penetration «Only operation approach» Congestions and other grid problems are solved at operational stage, sometime restricting DG RES injections «Active Network approach» Inclusion of ICT technologies, new connection & operational requirements, market based procurement of ancillary services from DER to solve grid constraints, combined planning&operational solutions, highly configurable settings. 9

10 Fostering the integration of larger amount of RES through Advance Metering and Smart Grids infrastructures RES Integration through Smart Grids / Smart Metering? Key Drivers Strong subsidies and countrywide commitments have incremented in a significant way RES penetration DG and RES increasing penetration is leading to the new Active network paradigm Positive business cases in many countries are encouraging Smart Grids / Smart Meters rollouts Key Questions Are the Power Systems ready to accommodate large amounts of non programmable energies? How to operate Power Systems with high penetration of RES maintaining stability and reliability? How to transform a traditional power system in a new «Active Power System»? How to optimize the deployment of Metering infrastructures of such complexity? How to deploy a robust and well performing AMM infrastructure, guaranteeing at the same time system interoperability? 10
