The Learning The Outputs The New Gaps The Legacy And Finally 2
THE LEARNING 3
On EVs and the Automotive Sector On driver behaviour On grids On alternative solutions On Commercial models So what have we learnt The industry is an exciting place, moving very quickly It s also highly aligned from politicians, through to the supply chain of the OEMs That behaviour can change quickly when customers are presented with the right products That clustering will be real similar demographics and irrational factors It takes about a week for an EV user s behaviour to settle down Weekday patterns differ from weekends and tend to be more onerous Winter is worse case than summer That EVs will have an impact on local grids, particularly when clustered It s more pronounced in networks where the ADMD per house was assumed to be <1.5kW 7kW charging is likely to have a more marked impact That demand side response (DSR) solutions can help solve the problem It works better in a residential setting than in a commercial one There are some technical challenges, which can be overcome, the commercial model needs further consideration 3rd parties can deliver innovation projects But there are key issues around risk sharing that need to be understood by all involved And it s not hands off for the DNO But we have proven it can work! Leasing of vehicles may accelerate uptake 4
Don t take our word for it Highlighted strengths Strong leadership by EA Technology Teamwork, dedication and long term commitment Recruitment Good management of customer relationships Timely and effective public engagement Good understanding of the data collected Dissemination of project learning Recommendations Ofgem must recognise the Third Party Lead Supplier in their role as project coordinator Technology risk mitigation Requirements for data collection and analysis Learning from the project should be incorporated into Esprit Further analysis of the data collected Extracted from the Draft Executive Summary from Ricardo UK s final 6 monthly report summing up My Electric Avenue 5

THE NEW GAPS 8
So what do we now need to investigate Embedding DSR Spotting clusters / investment triggers 7kW charging and bigger batteries When is the right time to roll out a solution What is the best way to roll it out to customers? How is it messaged to avoid alarmist headlines Where will they appear What are the tell-tails Which specific networks should we watch for Will people charge as frequently? Will they charge at home or at charging stations? What impact will this have on the network? V2G and cheaper storage What impact might this have on EV uptake....or grid support And when could it become a reality 9
THE LEGACY 10
Moving from TRL7/8 to TRL9 Esprit and DNO driven DSR: Technical changes needed Assess overall performance with network & review business case Then Alternative communications Embedded ICB in the charger (ideally an algorithm) to eliminate additional switch Refinement to the curtailment algorithm to take into account feedback from OEMs Incorporate transformer as well as feeder demand Full product respin Test with wide variety of 7kW vehicles 11
DNO driven DSR and Esprit: Commercial Model SDRC 9.7.1 - An Assessment of Esprit Integration 12
DNO driven DSR and Esprit: Roll out considerations Esprit (and any other form of DSR like this) consists of two elements Substation monitoring monitoring & control Charging point (switch or control) How to deploy: Deployment at the substation Rolled out when issue arises DNO purchases as cluster forms Needs to be able to communicate with ALL downstream chargers at this point Deployment in the charger Embed algorithm in charger but why would I (as a customer) do this? Incentive payment, or It s required (a Standard), or A hybrid 13
DNO driven DSR and Esprit: Roll out considerations Preventative Roll out algorithm to customer s chargers ahead of need Enabled by the DNO when tipping point reached Deployment of kit into substation that can communicate with ALL downstream devices Solution could be short term or indefinite (depending on network type) Needs messaging with the cluster when it s enabled Post-fault Retrospectively roll out when time comes (e.g. if substation fuses blow) Requires a retrofit device for chargers Deployment of kit into substation that can communicate with ALL downstream devices Likely to be a short term installation (but will depend on degree of overload) Needs messaging with the cluster when needed The highlighted areas need joined up thinking between Automotive and Utility Sectors 14
Keep talking: Work together The overlap today is thin We are championing the creation of an Automotive-Utilities Working Group Non-partisan, independent Investigate the issues in more depth..and develop solutions that work for all parties 15
Keep talking: Work together In principle support Automotive Nissan LowCVP OLEV Cenex Fleetdrive Electric Who else we would like on-board Automotive SMMT Other OEMs Charging point manufacturers Utility SSEPD NPg Utility Ofgem ENA Other DNOs National Grid Other key Stakeholders InnovateUK IET IMechE BEAMA Other key Stakeholders Policy makers Government 16
AND FINALLY - WHY IT MATTERS 17
Back where we started: EV uptake a fast ramp up 18
But the signals today are stronger than ever Cumulative car park of EV and plugin hybrids, extrapolating based on this year predicted year end sales (based on SMMT figures) with a sales growth rate of just 5% per year Based on a calculation of the MWh this represents running round as mobile storage resource on the UK streets. Assuming a blanket 24kWh for every EV and 4.4kWh capacity for every plugin Source: InnovateUK, December 2015 19
