Behind Volvo Group’s announcement of Mariestad energy park, stands a team of technical experts who paved the way for 70 MW of power and 260 MWh of energy storage. This is the story behind those numbers. We met with Mark Ellis and Victor Bertilson to learn more about how they work to turn those numbers into a flexible energy system capable of responding to the changing needs of the industry, the grid and energy markets.

Scaling an electric fleet increases the demands on charging infrastructure, energy supply, and grid capacity. A Battery Energy Storage System (BESS) helps fleet operators manage those demands, create capacity for further growth, and improve the economics of electrification.

With a total power of 70MW, the Battery Energy Storage System (BESS) installation will be one of the largest in Sweden and marks an important step in Volvo Group’s fossil free journey.

Volvo Energy has delivered ten PU2000 Battery Energy Storage Systems (BESS) to the Volvo Trucks plant in Tuve, Gothenburg. With a total power of 10 MW, the installation is one of the largest commercial and industrial battery energy storage projects in Sweden to date — and an important step in future-proofing one of Volvo Group’s key production sites.

As the demand for Battery Energy Storage Systems (BESS) continues to rise globally, safety remains one of the industry’s most critical priorities. Volvo Energy BESS comes with a unique direct fire injection technique that can significantly improve thermal runaway mitigation in battery packs for stationary energy storage applications.

Battery Energy Storage Systems, or BESS, are becoming increasingly relevant for quarry operations, where power demand, site conditions, and operational needs can vary significantly over the day or week. A BESS can make a real difference by helping operators lower costs, improve flexibility, add new revenue streams and make better use of available grid power during idle periods.

The electrification of commercial vehicles and machinery is a key component in the decarbonization and evolution of the transport and industrial sectors. With widespread availability, declining costs, rapidly improving infrastructure and clear economic benefits, adoption is expected to accelerate over the coming decade. However, practical and operational challenges still need to be addressed.

As Volvo Energy continues to push boundaries in energy storage and digitalization, the PU2000 Battery Energy Storage System (BESS) stands as a milestone, combining intelligent design, cyber-secure operation, and real-world impact.

GOTHENBURG, SWEDEN, 1 October 2025

Volvo Group is taking a major step toward sustainable industrial operations at its planned Mariestad plant, driven by the vision of “building electricity with electricity.” This initiative integrates cutting-edge electrification and infrastructure solutions to support Sweden’s environmental and energy goals while reinforcing Volvo’s commitment to innovation.
