The European Utility Industry Awards are hosted during European Utility Week, in the evening of the 15th November. The awards recognise and celebrate individuals and projects that have shown outstanding commitment and accomplishments towards a sustainable energy sector. If you have any questions about submissions or voting, please contact us.
Vehicle to Grid (V2G) technology deployment in Europe
In the recent years the Renewable Energy Sources (RES) have been deployed at a significant rate, decreasing the emissions of the energy production mix but increasing the variability and uncertainty of the energy production. Such variability may affect power system frequency stability, that relies on the constant balance between power generated and consumption Today, most of the power is generated by conventional power plants (fuel, gas, coal) that facilitates frequency regulation basically providing primary regulation or secondary regulation to the energy system. In the future, this balancing service could be provided in a competitive manner by the electric Vehicles (EVs), especially, because most of the time (typically about 90%) they are parked and can be connected to the low voltage grid Therefore, EVs will play an important role in future power systems.
On this regard,the world’s first fully commercial V2G hub is now operating in Denmark promoted by Enel, Nissan and Nuvve . Becoming the first customer to commercially integrate and host V2G units at its headquarters in Copenhagen, utility Frederiksberg Forsyning has installed 10 Enel V2G units and purchased 10 zero emission, 100 percent electric Nissan e-NV200 vans that will join the company’s fleet. hen the e-NV200s are not in use, they can be plugged in to the new Enel V2G units on site and can receive energy from and provide energy back to the national grid on demand, effectively turning the vans into mobile energy solutions.
Electric cars that can store clean energy and inject it into the grid to power the daily life of our cities. It’s not a futuristic project, but rather the result of a revolution that Enel is making possible with the Vehicle 2 Grid (V2G) project started in 2010. Transport is among the main producers of air pollution in urban centres. And if electric cars make an essential contribution in reducing CO2 emissions in cities, V2G vehicle help even more by turning cars into a strategic element for the development of smart cities.
We collaborate with Car manufacturers, like Nissan to develop this innovative system that allows car owners and energy consumers to use their vehicles as real “four-wheel mobile plants”, to store and feed back into the grid the energy that has not been used.
In France, for instance, where 38 million cars are driving and the current electricity generation is 130 GW, in a future in which all vehicles will be electric or hybrid, integration between the grid and vehicles will be able to generate the equivalent of a 380 GW virtual electric plant (three times the present generation capacity).
Cars using the V2G system can convey electricity to any other vehicle that needs to be recharged, to a home that simultaneously uses several home appliances, thus increasing the electricity demand, or to street lights that must ensure continuous lighting to roads.
Thanks to Enel’s e-mobility technologies, the energy stored by the electric vehicles is managed smartly, based on the grid’s actual needs, and electric vehicle owners become real energy distributors.
Electric drivers can recharge the batteries of their cars when energy costs and demand are lower, and can then use the stored electricity or feed it back into the grid just like an energy producer, with direct economic returns and benefits for the transmission adn distribution grids. The Vehicle 2 Grid system is an innovation that can improve our lives and make the world a better world for present and future generations.
The “four-wheel mobile plants” become a way to enhance clean energy as much as possible, increasing energy efficiency and better managing electricity consumption, reducing waste and costs of both producers and citizens.
We are opening a new era in which electric mobility fully becomes part of the domestic distribution grids of the whole of Europe. V2G creates an eco system that stably interconnects cars, the electric grid and citizens.
The world’s first fully commercial V2G hub is now operating in Denmark .

When the e-NV200s are not in use, they can be plugged in to the new Enel V2G units on site and can receive energy from and provide energy back to the national grid on demand, effectively turning the vans into mobile energy solutions. The total capacity made available by the 10 kW Enel V2G chargers amounts to approximately 100 kW. By participating in this initial project, Danish grid operator Energinet.dk is keen to apply the findings from the commercial implementation of the V2G hub to adapt the national network in order to better integrate EVs and provide ancillary services to stabilize the grid.
