2. Frankfurt (Germany), 6-9 June 2011 Background  UK response to climate change challenge Significant increase in contribution from renewables (2020) Decarbonisation of electricity system by 2030 Increasing electricity demand through electrification of heat and transport demand Energy efficiency, demand response, smart metering rollout  Objectives and scope Quantify the impact of the integration of transport and heat sectors on the UK electricity distribution network investment  Evaluate required investment under BaU and Smart Management scenarios Inform UK debate on smart metering functionality

3. Frankfurt (Germany), 6-9 June 2011 Penetration scenarios for EVs and HPs

4. Frankfurt (Germany), 6-9 June 2011 National level analysis – Electrifying heat and transport sectors

5. Frankfurt (Germany), 6-9 June 2011 Local level analysis: Impact of commuting driving patterns Significant opportunity to optimise charging as EVs will remain stationary over night Significant correlation in arrivals from work i.e. significant peak load imposed by EV charging 5

10. Frankfurt (Germany), 6-9 June 2011 10 Optimal EV response to electricity prices Price-based wind following may increase peak demand and overload distribution networks

11. Frankfurt (Germany), 6-9 June 2011  Paradigm shift from passive to active network management necessary to avoid massive distribution network reinforcement Estimated benefits of Smart Metering due to reduced investment in distribution networks are between £0.5bn and £10bn  Benefits of additional functionality of Smart metering potentially very significant  Continuing with asset based business model?  There could be conflicts between energy supply and network business objectives; Distribution System Operator function needed?
