6 My Electric Avenue Technical trial 100 customers in local clusters Social trial 100 customers across GB to provide comparison

7 Scope An Interim Solution Focused on Local street level network overloads only Applicable to Domestic (Home) Charging Not applicable where the customer is paying for a larger connection 7

8 Key Industry Facts Domestic EV charge point connectio ns do not require advance permission Domestic EV related upgrade costs are socialized. Low Voltage cables are protected by fuses. Industry Facts DNOs do not currently monitor load in detail on a street by street level A site visit is required to replace a fuse. Most networks are historically designed to <3kw. 8

9 Diversified Demand (kva) Network impacts 2.5 Revised domestic ADMD including EV charging (3.5kW charging units) :00 02:00 04:00 06:00 08:00 10:00 12:00 14:00 16:00 18:00 20:00 22:00 00:00 Time of day Residential EV Total

10 15% EV Uptake will saturate some networks

11 Diversified Demand (kva) Law of large numbers and diversity :00 02:00 04:00 06:00 08:00 10:00 12:00 14:00 16:00 18:00 20:00 22:00 00:00 Time of day Residential EV Total

12 At local level: no law of large numbers Plus Clustering

13 The Exceptional Scenario: In a small street somewhere in GB in March 2020 Mrs Smith purchases her first Plug in EV. She is the 5 th owner in the street. A week later, Mr Brown swaps his Plug in Hybrid EV for a Plug in EV. All is well for a couple of weeks but then at Easter weekend they are all planning a trip so charge their cars fully. It is also a cold Easter so local heating is on. The Local Substation Fuse blows leaving most of the customers in the street without supply. 13

14 The Exceptional Scenario: In a small street somewhere in GB in March 2020 Mrs Smith purchases her first Plug in EV. She is the 5 th owner in the street. A week later, Mr Brown swaps his Plug in Hybrid EV for a Plug in EV. All is well for a couple of weeks but then at Easter weekend they are all planning a trip so charge their cars fully. It is also a cold Easter so local heating is on. The Local Substation Fuse blows leaving most of the customers in the street without supply. 14

15 Key Facts that drive the need for a rapidly deployable solution Uncertainty until patterns established Clustering accelerates EV impact on some local networks Relevant Facts Rule of Large numbers does not apply to small local networks No advanced warning of new charge points or Change in EV type Exceptions Holiday weekend Post power interruption, Pre storm 15

16 EV Charge Management Social trial Minimum of 100 customers across GB to provide comparison Technical trial Minimum of 100 customers in (very) local clusters

17 Key Facts that explain why this solution now? DNOs have been allowed some funding for EV readiness, it needs to be used efficiently, it is customers money Research shows a healthy market for the provision of Charge Management solutions Relevant facts DNOs have a responsibility to keep the power on and the network safe We can continue to monitor and test the market for alternative solutions. Customer choice drives EV uptake, the trend can accelerate rapidly 17

18 Solution sits inactive until the local fuse is at risk Rules/ thresholds will apply as to how often this solution actively manages charging This solution is interim, it is not the only or the preferred solution. It is a tool to ease the deployment of EVs. DNOs will regularly test the market to identify permanent solutions where needed. The solution allows time for data to be gathered and other solutions deployed on an informed basis. The solution will go to tender, there will be no barriers to any tender response that meets the requirements economically. Key Features of the proposal The solution will only be used with customers consent with suitable customer engagement to explain the benefits Managed Charging should not impair the ability of a customer to charge their EV 18

19 Key requirements of tendered solution Can be installed at any location within a few hours. Can be installed simply. Can be partially or wholly redeployed (if only addressing the immediate EV Charge Management issue). Will function for all UK EV Chargers and car models. Can use widely available communications channels OR be standalone. Secure and safe 19

20 What else are we doing now: Co-ordinating with all DNOs through the ENA Working with key stakeholders in a range of projects Sourcing data to improve modelling of network headroom Sourcing data to improve anticipation of EV uptake Applying analytics to the analysis of combines data sets to provide greater insight Preparing to roll out targeted monitoring Preparing EV readiness teams to target locations freeing up network capacity, managing the assets and managing network losses. Leveraging Smart Meter data as it becomes available

21 Consultation will be published on Friday 23rd of March Thank You

24 Smart EV Project Overview Innovation project run by SSEN, delivered by EA Technology Goals: Define a technical specification Seek industry consensus Develop a consumer messaging strategy Steering group consisting of broad range of stakeholders Stakeholder input and consultation is a key aspect

25 The local network Invisible assets LV service cables LV Main Fuse 11kV:LV Transformer LV feeder: underground cable EA Technology OpenStreetMap, Mapbox Domestic cutout fuse

26 The local network Invisible assets

27 Managed (Smart) Charging What does this mean? Temporarily modifying the charge rate to support the energy system Three flavours of DSR markets: Flexibility Markets (System Operator) Energy Trading and Arbitrage (Energy Supplier) Demand Response to support networks (DNO) EA Technology OpenStreetMap, Mapbox Our specific focus (DNO use case): Keep Low Voltage networks within safe limits Potentially enabling the other use cases

28 Managed Charging Deployments (000s) EV Uptake (000s) Timescales Essential to act ahead of need Longer term: EVs are manageable, but it is likely to be a big impact Market based solutions smart, flexible energy system Shorter term: ,000 8,000 7,000 6,000 5,000 4,000 3,000 2,000 1,000 0 Concern is about local clusters Managed charging deployments (000s) EV uptake (000s) before market based solutions may be available Small numbers of deployments needed soon to support widespread uptake

29 The interim solution Technical description Three main components: 1. Substation controller Monitor the network Identify when support is needed 2. EV charge controllers Receive signals that load reduction is needed Switching or curtailment functions 3. Back office Manage the devices Reporting Devices fitted by the DNO at the customers premises accept to delay or curtail charging rate Back-office Distribution Substation A substation controller measures demand on the cable and assesses whether a managed charging event is needed

30 Open to innovative solutions Functional description Would be fairly easy to directly specify the technology Challenge not to constrain innovation Describe the constraints and the desired outcome the how is open Reduce overloads within about 10 minutes Rapidly deployable Can be fitted to all/most chargers Temporary optout mechanism Act fairly Recording features Transparency when operating Reliable and resilient

31 How would the solution be used? Use case 1: Post fault power restoration Need to act fast rapid deployment essential

32 How would the solution be used? Use case 1: Post fault power restoration Need to act fast rapid deployment essential Power outage suspected to be related to high EV uptake Install substation controller Seek consent from customers and install MEVC solution Investigate alternative options

33 How would the solution be used? Use case 2: High risk network insurance

34 How would the solution be used? Use case 2: High risk network insurance Monitoring / modelling suggests network is at high risk of overload Install substation controller Seek consent from customers and install MEVC solution Monitor system usage

35 Amount of time charging is paused per annum (minutes) Why Managed EV Charging? Customer Acceptance Small amounts of charge management allows a lot more vehicles to charge Customers would not notice most events (typical 50% rate for 30 minutes) Focus groups have indicated support by the majority For me, personally, it wouldn t make a difference 0 Amount of EV charge management 50% 60% 70% 80% Proportion of households with an EV on a single street If it s only minutes, that s not a problem, but as long as they stick to that I d find it a problem paying all that money for a car and not being able to charge it

36 Customer safeguarding Governance arrangements Recognised customers should have protection that the solution isn t being used outside of agreed parameters Proposed three key metrics: 1. Amount of daily charge management 2 hours maximum 2. Amount of monthly charge management 8 hours maximum 3. Period of operation Maximum of 18 months In all cases: market based solution takes precedence

37 Market offerings Three categories of market in this context Procurement of the interim solution Buying a system with an operational service Not buying a demand-side response service Procurement will be competitively tendered Procurement of demand-side response Buying a demand-side response service Ambivalent to how it happens Recruitment up to service provider DNO benefiting from wider time-of-use pricing

38 Why not rely on market-led solutions? It s all about risk EVs open up opportunities for customers to truly engage with the energy market Smart charging could be a key enabler From today s viewpoint, there s some challenges: Most chargers are not smart Few customers have time of use tariffs (excl. E7) Still debate over the effectiveness of TOU pricing, especially for local network peaks British Gas

39 Should customers be compensated? Socialisation of costs debate Cost of reinforcement of networks is socialised across GB customers do not pay directly: Cost to the customer of electricity distribution in remote Scottish highlands is the same as central Aberdeen Therefore reinforcing due to EVs also impacts (e.g.) customers who choose not to drive Should EV drivers also help to solve the issue? The household control equipment will use electricity (probably not much) but should customers at least be compensated for the running cost? EA Technology OpenStreetMap, Mapbox

40 Future, smart system Potential use of smart meters Not proposed as a DNO-led system general to the energy industry Investigated the potential use of smart meters Working with BEIS, input from SECAS and DCC Consultation is an opportunity to take input on this potential option Modification raised within SEC Source: DCC ( DCC Data Communications Company SEC Smart Energy Code SECAS Smart Energy Code Administrator and Secretariat

41 Potential architecture HAN-connected Smart Charger

42 Benefits of using smart meter infrastructure HAN-connected Smart Charger Leverage of existing investment Potentially lower overall cost to customer Near ubiquitous roll out Robust security framework Consistent and well tested technical standards Use of existing communications service 99% coverage Pave the way for demand-side response with appliances

43 Consultation (interim solution) What insight are we looking for? Availability of market-led solutions Technical feasibility Customer consent Market readiness of interim solution Compensation Governance arrangements Best interest of the customer? General feedback

44 Consultation (longer term solution) What insight are we looking for? Technical feasibility Pros and cons of enabling markets General feedback Should the industry move forward with this solution?
