Benefits of Advanced Smart Metering for Demand Response
based Control in UK Distribution Networks
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

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

Price-based wind following may increase peak demand and overload distribution networks
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?
