Q&A David Thornton – EV Express EV charging opportunities

Presentation supported by: Presentation format

• 2 parts • Introductory info (EV Express) • Applications, opportunities and considerations in various settings (Project EV) Growth of EV new car regs Charge points – essential info

• Premium pay for Fast chargers: quicker charge time • 7kW (single phase) to 22kW (3 phase) experience • 100% charge times (e.g. Renault Zoe): 9-12 hours to 3-4 hours • Range (e.g. Renault Zoe = 245 miles). 1 hour charge = approx. 27 miles on 7kW unit

Rapid chargers: • 40kW to 100kW+ (spec rising to 150kW) • 100% charge times (e.g. Renault Zoe): 30 mins to 2 hours, depending upon output and AC or DC options Fast chargers

• Residential & commercial settings • Smart charging – use phone app to charge at appointed time, e.g. optimum off peak time • Destination charging: coming for another purpose other than charging • Good ROI models Rapid chargers

• Need for speed • Strong ROI models – much greater set up cost, but will attract users to travel to it • Clear evidence of users prepared to pay premium for convenience of quicker charge time • Creates secondary spend – e.g. food outlets around charge point Charging options for residential accommodation Charging options for individual businesses Accessing grants

• OLEV approved lists for grant funding – commercial & domestic • Some units fit both lists • Workplace Charging Scheme (£350 x 40 chargers= £14000) • Home charge grant (£350) • Grant paid to OLEV approved installer • Grants not available where commercial gain / advantage and owner controls tariff Applications, opportunities & considerations in various settings

Like the slide im just looking for the information and feels like we have made it in a rush, have another go, I like what you have done with the titles USP’s maybe bigger

You can also charge through solar power online with Solar…

Fast charging mode incorporates any solar export and tops up any remaining power from the grid to the full capacity of the charger, standard operation.

Solar Eco mode charges incorporating any solar export and tops up any remaining power from the grid, but with a limit on the amount of power it takes from the grid up to a maximum power of 3.6KW.

Solar Eco+ charges exclusively with solar exported power and will start charging at 1.4kw, which is the regulatory minimum charging requirement. Increasing Location Capacity with Battery Storage • IP55 Protection, outdoor applications • Flexible combination, suitable for industrial and commercial energy storage • Standard all-in-one ESS container applications • Shipped 300MVA/350MWh+ • Integrated Design, easy on-site

• Short installation cycle, easy maintenance installation and maintenance • Air cooling • Air cooling

Q&A EV Application Processes Ian Jessiman EV Account Manager SHEPD/North EV Connections Early engagement

Early engagement Application and Design

Applying for and designing your connection Connections

Delivering your connection Getting you connected

Customer service/ Feedback feedback Early Engagement

Come and speak with us as soon as possible as we will be happy to help you firm up your requirements prior to you submitting your connection application.

We offer support and advice through our: • Dedicated teams of Account Managers (contact info for SHEPD and SEPD) • Pre-application meetings and local connection surgeries (request meetings via [email protected] or register via our online event calendar) • Website and EV guide ENA Process ENA has a standard process for connection of EVs to DNO networks:

• A new EV and Heat Pump notification and connection process was released by Energy Networks Association (ENA) in 2019 • Helps installers identify when an installation is ‘Connect & Notify’ vs ‘Apply to Connect’ • Heat Pumps will have an online database associated with the process; ENA intend to do the same thing for EV Charge Points (particularly DC units) • Now includes commercial properties and DC charge points • Typically (but not always) slow chargers can ‘Connect & Notify’ and fast chargers need to ‘Apply to Connect’

We encourage all installers to talk to us and use the notification/application process

ENA application form http://www.energynetworks.org/electricity/futures/electric- vehicles-and-heat-pumps.html Connect & Notify Only possible if • The Maximum Demand (MD) is not greater than 60A per phase (13.8kVA single phase) • The MD exceeds 13.8kVA and the connection is CT metered, but the aggregate Maximum AC output of the EV charging points are equal or less than 30% of the Maximum Import Capacity of the supply

Your installer will, however, need to contact us prior to installation if:

• The MD is greater than the supply capacity • There are safety concerns with the cut out • There is uncertainty over the supply capacity • The connection is a looped supply or if this is unknown • The survey indicates that the connection needs upgrading

We can then arrange a load check and advise your installer but if your connection or the adjacent network needs upgrading then we will need to prepare a quote for you to consider.

Once you have accepted our quote we will then progress the works and, on completion, will advise your installer that they can connect your charger. Applying for your Connection

Information we need to design your connection ENA application form • Name of applicant http://www.energynetworks.org/electricity/ • Address of applicant futures/electric-vehicles-and-heat- pumps.html • Name of site contact (if different from applicant) • Address and plans of connection site (location and site plans) • Location of supply point (meter) marked on site plan • Number, location and loading of EV chargers • Total load requirements (kVA) • Any generation on site (energy storage, PV etc…) • Letter of authority (if you are not the landowner)

How to apply • Online • Email ENA EV Connections Forms

• There are two types of forms; one for a single connection and a spreadsheet for multiple EV connections • The spreadsheet can be used for multiple addresses as well as multiple EV/HP Units on the same MPAN • The word document is only for one unit being installed on one MPAN • Captures details such as owner, location, MPAN, max demand, capacity, connection type, etc EV Webpage Review our online Contact guides webpage & guides to help you when EV guide considering type of charger, power rating, charging time Get in touch Pre-application support is and locations available through Account Managers, meetings, online meetings and surgeries

Apply early Design to final connection can take up to 10 months Summary depending on the size and complexity of connection requested. Applying as early as possible will help us meet your delivery timescales EV Design Processes James McNeish Connections Design Manager Designing the Network

• Recently overhauled how we do LV studies • Revised connection design for LV connections below 69 kVA • Now take Diversity into account even for EV chargers on LV studies • Load profiles used as power is used at different times during the day and night • Will allow more connections to the network than previous Designing the Network

What does this mean for EV connections? • Some connections can be completed and no network studies required • SSEN accept the risk if there are any issues with this • Where network studies are done, these consider Diversity • LV models completed using Windebut software

• Domestic EV profile • Commercial EV profile Designing the Network What is Diversity and how does it benefit EV?

If we take the example of fifteen 50kW EV chargers connecting to the network on separate connections to the same transformer

Previously Total Load would have been 750kVA

This would require a 800kVA transformer

Large LV cable, several feeders

Large costs, 3 feeders on 300mm cable required Designing the Network What is Diversity and how does it benefit EV?

Diversity reduces the amount per customer

Assumes that the use is not the same for every customer at the same time

Reduction is exponential

Single customer there will be no diversity. 10 customers, it will be reduced

Only takes into account single customer type Designing the Network What is Diversity and how does it benefit EV?

Taking the previous example into the new method, fifteen 50kW chargers connecting to a new transformer

Total demand would now be 473kVA

This would mean smaller transformer and smaller cables could be used. Only two feeders of 185mm cable

Saving money for the connection and allowing connections for less cost

Network still remains within limits and capacity is still available What do we need from you?

• Only apply for the size that you need • Designs and costings will be based on the requested capacity • If you request 69kVA but only require 50kVA, you may pay for unnecessary upgrade works to the network • If you are unsure, get in touch. We are more than happy to discuss connections prior to application • Engage with us Go to Enter the Use the link code Audience provided in IOW20 Q&A function IM chat to ask a question or the Teams Chat facility

Q&A Yuan Gao – System Planning Overview Overview of electricity transmission • Electricity is transmitted down from National Grid transmission system to SSEN distribution system and eventually to end users.

• The higher the voltage, the bigger capacity rating. EHV/132kV HV networks LV networks networks • EV charging facilities are normally connected at HV or LV networks.

• Assets overloading, typically on circuits and transformers, is a potential concern when connecting EV charging facilities.

73 Overview of EHV/132kV networks in IoW • IoW networks are fed by Fawley GSP (Grid Supply Point 400/132kV), Cowes and Wootton Common BSP (Bulk Supply Point 132/33kV) and 9 local primary substations (33/11kV).

• Capacity required for EV charging facilities at LV/HV networks will be subject to capacity availability at EHV/132kV networks.

• Network reinforcement will be required if there is no sufficient EHV (33kV) networks capacity. 132kV networks

74 Capacity availability at primary substations

How many EV chargers can be supplied** • Capacity is generally available at Capacity Primary Substation 132kV networks feeding IoW. availability* Tesla super charger Domestic EV charger (120kW) (7kW) Cowes 9MVA 75 1286 • Shalfleet, Freshwater and Sandown have limited capacities. Newport 9MVA 75 1286 Large scale of EV charging Shalfleet 5MVA 42 714 infrastructure should be well Freshwater 5MVA 42 714 planned in advance in these areas. Binstead 7MVA 58 986 Ryde 10MVA 83 1411 • Comparing to EHV/132kV Sandown 3MVA 25 425 networks, HV and LV networks Shanklin 10MVA 83 1411 are more of concern due to their smaller capacity ratings and Ventnor 10MVA 83 1411 generally bigger utilisation. * This capacity availability is only indicative. The network capacity availability can only be confirmed with a network assessment on the time that the inquiry is made. ** The number is only an indicative number to demonstrate the relationship between capacity availability and number of EV chargers can be supplied. Practically, more chargers would be supplied when considering other factors such as diversity etc. 75 Electric Vehicles Uptake in the Distribution Networks Isle of Wight
