V2G technology

A pilot on vehicle to grid (V2G) technology has been launched in Amsterdam.

Electric vehicles (EVs) charging solutions firm NewMotion has partnered with utility Alliander, technology company Enervalis and innovation platform Amsterdam Smart City (ASC) to implement the trial project.

The initiative aims to test the ability of V2G technology to store energy during times when demand on the grid is stable and integrate it back to the grid for reliability during times when the main energy system is stressed.

V2G charging stations have been installed for the public at locations including shopping malls.

The pilot includes the trialing of Vehicle to Office system. Under the initiative, charging stations have been installed at offices of accounting firm PricewaterhouseCoopers.

Employees can charge their EVs at work when onsite generation is high and supply stored energy back to the company’s grid network when demand on the internal network or the main grid is high.

Amsterdam is implementing the pilot as part of the City-Zen programme which is designed to develop energy efficient and smart cities throughout Europe.

Sytse Zuidema, CEO, NewMotion, said, “In the Netherlands alone, we’re expecting to see around one million electric vehicles on the roads by 2025. At the same time, the decentralised generation of electricity through solar panels and wind turbines is responsible for an ever-increasing share of the total electricity supply.

"Due to the irregular availability of sun and wind, it is imperative that storage capacity becomes available, so that sustainably generated electricity can be stored for peak moments in energy demand. These developments pave the way for the broad deployment of V2G technology.”

Annelies van der Stoep, Project coordinator of energy transition, ASC added, "V2G is definitely one of the technologies that can make an important contribution to sustainable and energy-efficient cities. We are proud to be part of this world premiere.”

Marisca Zweistra, Senior project manager at Alliander said, "We are testing the impact of V2G on a low-voltage network in close collaboration with our partners. In addition, we want to see whether V2G has potential as a back-up in the event of electricity failures and if more of the self-generated solar energy at these offices can be used for the electricity supply of these locations. If this is the case, there will be less load on the grid and as a result, fewer expensive power cables will have to be installed.”
