EDF Energy & Nuvve To Install 1,500 V2G Chargers In UK

NOV 4 2018 BY MARK KANE 8

Electric cars will be able to supply up to 15 MW of power

EDF Energy and Nuvve Corporation announced that they intend to roll out 1,500 smart chargers in the UK with V2G capability.

The idea is to offer the chargers to EDF Energy’s business customers that use electric cars (EV models and charger types were not disclosed in the press release, but we bet on the Nissan LEAF/e-NV200 and CHAdeMO). Assuming that project will be completed, the two would be able to supply up to 15 MW of power (of course, if the cars are connected to the chargers and charged enough). On average it would be some 10 kW per car/charger.

As we understand, the business model here would work like this – customers purchases 10 kW DC chargers (higher charging power than in the case of typical Level 2 AC at 7 kW in the UK) probably at a lowered price. Then, EDF Energy and Nuvve are able to sell a certain amount of electricity with profit at peak demand.

Whether it makes sense or not? Only time will tell.

“The chargers will be offered to EDF Energy’s business customers and will be used at its own sites to provide up to 15 megawatts of additional energy storage capacity. That’s the equivalent amount of energy required to power 4,000 homes.

The stored electricity will be made available for sale on the energy markets or for supporting grid flexibility at times of peak energy use.

Smart charging is expected to play a significant role in balancing the grid as the country moves towards wider adoption of electric vehicles (EV). V2G chargers allow a two-way flow of electricity between an EV and the charger, representing a potentially valuable opportunity to further enhance the electricity system benefits of EVs through provision of large volumes of cheap storage and flexibility.

Using the V2G chargers, EVs give unused electricity back to the charger for customers to either use the energy themselves, send it back to the grid, or to participate in energy markets, providing savings on energy costs and generating additional revenues.

EDF Energy is the largest electricity supplier to UK businesses and its partnership with Nuvve could see the largest deployment of V2G chargers so far in this country.

More than one million new vehicles are bought by businesses each year1 and the UK Government has pledged that by 2030, at least 50 percent of new cars and 40 percent of new vans sold in the UK will be electric2. V2G chargers could help businesses generate revenues from vehicles that have previously only been a cost on their balance sheet – saving hundreds of pounds per vehicle a year.”

“EDF Group and NUVVE have signed a strategic partnership agreement with a view to forming a joint venture to develop these solutions in Europe. The San Diego-based green energy technology pioneer has deployed V2G projects on five continents including the world’s first fully commercial V2G hub in Denmark which has been operational for two years now.

Earlier this month, EDF President Jean-Bernard Lévy detailed the Group’s strategic plans on electric transport, including its plan to be the leading energy company for EVs by 2022 across its four largest European markets: France, the United Kingdom, Italy and Belgium.”

Beatrice Bigois, Managing Director of Customers at EDF Energy, said:

“With 55 percent of new vehicles coming on to the road through businesses3, they will play a key role in the transition to electric transport. Through this partnership with Nuvve, we are investing in smart technologies that will help our business customers electrify their fleets in a cost effective way and support the UK’s ambition for clean growth.”

Gregory Poilasne, Co-Founder and CEO of Nuvve, said:

“Nuvve is proud to be working with EDF Energy to commercialize our V2G charging technology in the UK. The UK is ahead of the game when it comes to integrating wind and solar on the electric grid and V2G is the perfect way to supplement these efforts.”

Energy and Clean Growth Minister Claire Perry said:

“Thanks to government investment, we are a world leader in vehicle-to-grid technology which can help balance our energy needs and bring about a smarter, more flexible energy system as part of our modern Industrial Strategy.

“These 1,500 electric chargers will provide much needed green infrastructure for businesses as they seize the opportunities of the electric vehicle revolution, reducing running costs, improving air quality and unlocking the capability to store energy which can be transmitted back into the grid when it’s needed most.”

I am glad to see this focused on fleets instead of individual EV owners. There will be additional battery degradation using V2G and fleet owners need to be aware of how much this will cost them. Fleet owners will be in a much better position to evaluate this cost than individual owners.

trackdaze

V2g doesn’t necessarily degrade the battery as much as you might think.

Batteries don’t like sitting with high SOC. So a little draw early on after parking and connecting to a charger coupled with charging closer to departure have seen battery degradation profiles improve over the norm in recent V2g pilots.

In any event the €1000+ profit turns fuel costs into fuel pofits

That depends how you define “the norm”. If you mean charging to 100% and letting it sit there, even when you know you won’t use the vehicle until the next day, then yes, some partial discharge in between might potentially be beneficial. However, even more beneficial is just not charging it to 100% in the first place until you are likely to need it…

In other words, that’s just a spin trying to suggest a benefit from V2G that in truth comes from a rather orthogonal change that hides the undeniable extra degradation from V2G itself.

Huh.
Are there any EVs currently sold in the UK, or planned to be sold in 2019, that support V2G? AFAIK, only the Nissan LEAF & e-NV200 support V2G, and that only in Japan except if an expensive inverter is added to the car.

The V2G units are all bidirectional chademo chargers. Not cheap but prices are dropping.

Gilles

All cars using Chademo are V2G compatible nothing to add. It’s the charger that do everything.

wavelet

Are you sure about that? From what I recall reading, the CHAdeMO standard indeed has _optional_ support for V2G, but LEAFs outside Japan do not implement it by default, meaning retrofits would be required.

antrik

I doubt the car needs an additional inverter. It does need to be prepared for handling bi-directional energy transfer — but that’s probably not a very expensive change. (Maybe even software-only? Not sure…)
