V2G: Learnings from 5 years of Development
V2G Timeline
1997
Study – EV’s as a new source of power for
Utilities
2010
Release of the first Nissan
LEAF and start of
commercially available EV’s
2011
Tohoku Earthquake
& Fukushima
Nuclear Crisis 2012
Launch of Nissan
LEAF-to-Home Unit
2016
Cenex installs UK first V2G Unit
(Project ITHECA) at Aston Uni
Nissan / Enel launch first
commercial V2G hub in Denmark
EU projectSEEV4-City starts,
demonstrating V2G as part of a
smart city
2018
20 V2G projects,
consisting of:8 Feasibilities
4 Collaborative R&D
8 Demonstrators
2017
Cenex installs first domestic V2G unit in UK (project EFES)
EU demonstrator Project CME
investigates smart city energy
management systems including
V2G
2019
EFES Decommissioned – Becomes first
V2G Unit installed in a meeting
room!
Number of V2G terms exceeds
number of Installations
2020
CCS goes SMART, enabling V1G
support
First sub –£2,000 V2G
Unit released
2025
CCS supports full V2G
Total V2G Units in UK reaches
2,021
2021
V2G ‘Valley of Death’ as Innovate
projects end
2022 DC V2G becomes a thing of the past and is superseded
by AC
2060
UK achieves first day powered
entirely by EVs
2055V2G installed as standard
with every new PV system
2035

What it does:• Everything ‘Smart’ charging can do, but better!• Off-set building demand• Provide 3rd party flexibility services
Current Status:• Mostly R&D with limited commercial availability• Widely available commercial units expected from 2020/2021• Additional network challenges for installing as counts as a generator
‘Vehicle-to-Grid’ (V2G)
Vehicle-to-Grid (V2G):
A system whereby plug-in electric
vehicles, when connected to electric
vehicle supply equipment (EVSE), can
provide bi-directional flows of energy.

V2G: Learnings from 5 years of Development
V2G Strategy – Customers
Key Lesson: Not all users are the same and their differences will impact the value they can gain from V2G
9
V2G: Learnings from 5 years of Development
V2G Strategy – Key Revenue Streams
FFR 24/7
FFR EFA
Key Lesson: There are some ‘key’ revenue streams which make up the greatest value. BUT, this can differ slightly from user to user.

V2G: Learnings from 5 years of Development
What could a domestic customer make with V2G?
Net savings from V2G: £486
Net savings from Smart Charging: £50
75% plug-in rate
Higher plug-in rate drives up grid service income
Grid Services Included: FFR, STOR, DTU.
Key Lesson: A good business case is complicated and takes time, but allows you to be clear about what you need and what you can achieve.
11
V2G: Learnings from 5 years of Development
Hardware Selection and Due Diligence
• Still early stages of development
• Limited and varying features
• OCPP1.6 / 2.0
• AC, DC, CHAdeMO and CCS
• EV Warranties
Key Lesson: Make sure you know how you want to use V2G before you go to tender.
12
V2G: Learnings from 5 years of Development
Installation & Operation
• Impact of size and weight
• Interacting with other ‘Smart’ devices
• Designing for safety
• Wired vs wireless comms
• The grid connection process in the UK
is one of the most complicated globally,
taking up to 6 months to connect
Key Lesson: Every site is different and this needs reflecting in the system design.
13
V2G: Learnings from 5 years of Development
Asset Testing for Grid Services
• Technical requirements for
providing grid services are still
tailored towards large
generation sites
• Extra requirements (e.g.
settlement meters) = extra
costs
• Cost of validation (Role of the
ITE)
Key Lesson: A V2G unit isn’t automatically qualified for grid services. Additional time and cost is required to make this happen.
14
V2G: Learnings from 5 years of Development
Customer Acceptance
Positives:
• Easy adapting behaviours
• Greater complexity = simplicity?
Negatives:
• Lack of awareness
• <10% conversion rate …when
free!
Key Lesson: Most customers want to simplify their lives and to accept added complexity (even perceived) requires a significant benefit.
