Kempower and Windrose use megawatt charging system in North America

Kempower, EV Realty and truck maker Windrose have started using megawatt charging system in North America to recharge an electric truck. This happened in San Bernardino, California, and was the first MCS charging session with a Kempower Mega Satellite MCS installed in North America. This marks “a concrete step toward commercial availability of MCS charging as a real, working solution for North American fleet and charge point operators”, according to Kempower.

Megawatt charging system in North America

Indeed, EV Realty’s charging hub features a 1,200 kW Kempower Power Unit connected to two Kempower Mega Satellite MCS dispensers, capable of delivering up to 1.2 MW and 1,500 A of continuous output. Combined with liquid-cooled cable technology, the system is designed to support sustained high-power charging and enable efficient turnaround for heavy-duty electric fleets. The site is set to open in April 2026.

“Megawatt charging is here to stay!”. Our interview with Antti Vuola (Kempower)

Antti Vuola, VP Products at Kempower, was one of the main speakers at the first edition of the Live Winter Days organized by the Finnish charging systems manufacturer. We had the opportunity to participate in the event in Sweden and meet Mr Vuola, whose vision about the future of electric industrial…

The MCS standard enables higher charging speeds, stronger standardization and enhanced operational flexibility for operators. Future heavy-duty trucks are increasingly expected to incorporate MCS charging capabilities with globally leading truck manufacturers already offering the technology. Kempower stated that “as new trucks come to market with a longer range and with MCS charging capabilities, there will be a growing need for MCS-capable charging infrastructure that works across vehicle manufacturers in real world operations”.

Statements from the partners

“MCS is a potential game changer for fleets looking to reduce dwell times and improve the efficiency of their operations. Fleets are excited about the trucks but have questions about where they will be able to charge,” said Suncheth Bhat, Chief Commercial Officer at EV Realty. “We are building sites that can serve any heavy-duty truck, including those utilizing MCS. This test confirms that we will be ready for real-world MCS charging when the trucks hit the road later this year.”
