TSG delivers the world’s largest fast-charging hub for heavy vehicles

Our Charge team at TSG Netherlands delivered a solution with Kempower for the world’s largest fast-charging plaza for electric trucks and off-highway vehicles. The Watthub has been officially inaugurated in Geldermalsen, in the Netherlands, with the presence of the Dutch King Willem-Alexander.

The Watthub project in numbers 

TSG Netherlands designed and built the WattHub electric charging hub, which included supplying and installing 36 Kempower chargers and six 600 kW transformer stations. TSG also handled all associated electrical work at the site, which runs exclusively on wind and solar energy.

With a total capacity of 3.6 MW, the realisation of WattHub represents a significant step in the construction industry’s transition to renewable energy technologies that produce zero emissions.

The 36 Kempower Satellites chargers are controlled in groups of six and provide between 25 and 400 kW of maximum charging power. This is the fastest charging speed available in the entire country.

Geldermalsen is strategically located between the city of Rotterdam, the second largest in the country, and the highway to Germany, making it an ideal stop for electric truck drivers in the coming years.

Kempower has also provided its Kempower ChargEye Depot Master charge management software for the WattHub charging hub. It is a cloud-based system that provides secure charging monitoring and management, minimizes electricity costs for charging, and dynamically distributes power to the chargers, eliminating the risk of overloading.

“We are pleased that WattHub is now open and accessible to Dutch electric vehicle drivers, and that its impressive charging capacity is being fully utilized. The charging hub has already played a key role in the electrification of fleets and heavy construction equipment in the region and has provided a solution for the previous defect sufficient infrastructure for charging electric trucks,” said Kempower CEO Tomi Ristimäki.

Tommy van der Sluijs, EV Business Development Manager at TSG Netherlands adds: “The construction of the first WattHub location is a great achievement that we have completed together with Kempower. We are very proud to share our decades of experience in being able to use e-mobility to contribute to zero emissions in construction projects and charging heavy equipment.”
