Dutch football stadium combines EV charging and energy storage

A combination of charging infrastructure for electric vehicles and energy storage will allow visitors to a Dutch football stadium to charge their electric vehicles with power from renewable resources.
Dutch company Alfen is delivering this integrated project at the Cars Jeans football stadium in The Hague for its client Scholt Energy Control, supported by grid operator Stedin and the municipality of The Hague. The project is expected to be operational early this year.
During the daytime, the stadium, home of Dutch football team ADO Den Haag, can generate its own energy from solar panels on its roof. This energy is mostly needed at night, to light the stadium but also to charge the increasing amount of electric vehicles of its visitors. Alfen's energy storage system can store the solar energy that is generated during the day, and supply this energy to the electric vehicles during the night.
"Through this initiative, renewable energy can be used locally for the electric vehicle charging hub,” said Ton Koning, programme manager for air quality at the municipality of The Hague. “We hope this will further stimulate the use of electric vehicles and consequently improve the air quality in our city."
For this project Alfen will supply a charging hub for electric vehicles consisting of 20 charge points to the municipality of The Hague, including a load-balancing platform to increase the use of the existing grid connection. This charging hub will be connected directly to Alfen's energy storage system. Alfen will also supply its remote management platform and connect the system to renewable energy sources and the electricity grid of Stedin.
"This project brings together all of Alfen's areas of expertise: grid connections, EV charging equipment and energy storage,” said Andreas Plenk, global sales director for energy storage at Alfen. “Integrating these areas of expertise will play an increasingly important role to incorporate the growing amount of renewables and electric vehicles, as these are causing imbalance on the electricity grid."
This storage system is the second project that Scholt Energy Control has awarded to Alfen this year. Scholt is an energy supplier to businesses in Belgium, the Netherlands and Germany. In May last year, Alfen delivered the first storage system in the Netherlands connected to a wind farm for a consortium involving Scholt.
"This project is truly unique in the combination of use cases,” said Sander Drissen, business development manager at Scholt Energy Services. “We will use the battery of Alfen to store the oversupply of renewable energy generated during the day. This energy can then be used in the evenings when it is most needed. In this way we make optimal use of the generated renewable energy. We will also smooth out the grid impact of a large number of electric vehicles that plug in at the same location at the same time. And finally, when the stadium is not being used, we can use the storage system for energy trading to further improve our business case."
Paul Broos, project manager at grid operator Stedin, added: "Integrating smart charging and storage will be of increasing importance to avoid sizable grid investments as a result of the growing amount of renewable energy sources coming on line in combination with the roll-out of electric vehicles."
With smart grids, energy storage systems, charging stations for electric vehicles, and a diverse portfolio of other products, systems and services, Alfen has a connecting role in the energy grid. Its transformer substations provide millions of households and companies with energy, while thousands of electric vehicles make daily use of Alfen's charging stations.
The energy storage system is used for applications such as load balancing, energy trading, frequency regulation and creating autonomous electricity grids in combination with solar or wind energy.
Scholt Energy Control is active as a supplier of electricity and gas to the business market in the Netherlands, Belgium and Germany. The company’s headquarters are in Valkenswaard, Netherlands, and it has offices in Belgium and Germany.
