Volvo Group Plans Major Mariestad Energy Park With 70 MW/260 MWh Battery Storage and Future Test Bed for Advanced Energy Solutions

Volvo Group Plans Major Mariestad Energy Park With 70 MW/260 MWh Battery Storage and Future Test Bed for Advanced Energy Solutions

(IN BRIEF) Volvo Group has announced plans for a new energy park in Mariestad, Sweden, combining a large-scale battery storage facility with a future real-world test bed for advanced energy solutions. The first phase is expected to provide approximately 70 MW/260 MWh of storage capacity, using Volvo Battery Energy Storage Systems from Volvo Energy, and is scheduled to become operational during 2027. The facility will support regional grid stability by storing electricity and feeding energy back into the local network when required, an important capability in a region that contains much of Volvo Group’s Swedish manufacturing base. The second development track will create a demonstration and testing environment where Volvo, customers and partners can evaluate new energy technologies under real operating conditions. The project will be located near Volvo Group’s planned battery cell production plant, scheduled to start manufacturing after 2030, and close to its existing Skövde powertrain facility. Together, the investments are intended to strengthen Volvo’s regional industrial cluster while supporting electrification, decarbonisation and the development of more resilient energy systems.

(PRESS RELEASE) GOTHENBURG, 10-Sep-2026 — /EuropaWire/ — Volvo Group has announced plans to develop a major energy park in Mariestad as the next phase of its expansion in the region, combining large-scale battery energy storage with a future test environment for innovative energy technologies.

The proposed Volvo Mariestad energy park will be located near the Group’s planned battery cell manufacturing site and developed through two parallel tracks: a utility-scale battery storage facility and a test bed for future energy solutions.

In its initial configuration, the park is expected to provide approximately 70 MW of power and 260 MWh of battery storage capacity, which Volvo Group says would make it one of the largest energy parks of its kind in Sweden.

Energy park to support grid stability and regional resilience

The first phase of development will focus on installing large-scale energy storage capable of storing electricity and supplying it back to the local grid when required.

Volvo Group plans to use Volvo Battery Energy Storage Systems (BESS) supplied by Volvo Energy for this stage of the project.

The storage facility is intended to provide flexibility services to the regional electricity market, allowing stored energy to flow back into the grid during periods of higher demand or when additional capacity is required.

Volvo Group said this capability can strengthen both energy access and resilience in a region characterised by significant industrial electricity consumption.

Mariestad project supports major Volvo industrial region

A substantial proportion of Volvo Group’s Swedish manufacturing operations are located in the surrounding region, making grid capacity and resilience increasingly important as industrial electrification progresses.

The Mariestad energy park is intended to provide an additional source of flexibility while supporting the broader transformation toward lower-emission transport and industrial production.

By locating large-scale storage close to current and future manufacturing operations, Volvo Group expects to develop practical experience in managing energy systems within an industrial environment.

Future test bed to develop new energy solutions

Alongside the battery storage installation, Volvo Group intends to establish a real-world test bed for new energy technologies and services.

The site will enable the company, customers and external partners to test energy solutions using actual operating conditions and commercial use cases.

Volvo Group said this will provide learning opportunities as it develops and expands energy-related products and services for customers undergoing their own transition toward lower-emission operations.

The energy park is also expected to serve as a demonstration facility where customers can see technologies working at industrial scale.

Facility expected to begin operations during 2027

The Mariestad energy park is expected to become operational during 2027, with development planned to continue incrementally over time.

The initial 70 MW/260 MWh storage facility will establish the first major component of the project, while additional test and demonstration capabilities can be introduced as new technologies and business opportunities develop.

Volvo Group sees the phased structure as a way to create immediate grid-support capabilities while maintaining flexibility for future expansion.

Lars Stenqvist highlights decarbonisation and energy-system benefits

Lars Stenqvist, responsible for the development of the Mariestad site at Volvo Group, described the initiative as a natural next step in the company’s development of the location.

He said the project reflects Volvo Group’s vision for a more robust, flexible and sustainable energy system.

Stenqvist highlighted the scale of the planned battery storage facility and said the approximately 70 MW/260 MWh installation will support both Volvo Group’s and Sweden’s decarbonisation ambitions.

He added that the energy park will provide an important test environment for developing and improving future energy solutions for Volvo customers.

Project complements planned battery cell production facility

The energy park will be developed close to Volvo Group’s previously announced large-scale battery cell production plant in Mariestad.

That facility is intended to help meet growing demand for batteries used in battery-electric heavy-duty vehicles and machines, with production scheduled to begin after 2030.

The proximity of the battery cell plant and energy park creates opportunities for shared infrastructure, technological capabilities and industrial synergies.

Together, the developments are intended to establish Mariestad as a strategically important location within Volvo Group’s broader electrification activities.

Skövde powertrain plant strengthens regional industrial cluster

Volvo Group also operates an existing powertrain manufacturing plant in nearby Skövde.

The Mariestad battery cell factory, planned energy park and Skövde operation will together strengthen the Group’s industrial and logistics cluster in the region.

Volvo expects this concentration of manufacturing and energy infrastructure to create opportunities to share capabilities and support the transition of its Swedish industrial footprint toward increasingly electrified products and operations.

Energy storage becomes part of Volvo’s wider electrification strategy

The Mariestad initiative reflects Volvo Group’s growing focus on the wider energy ecosystem required to support electrified transport.

As demand for battery-electric trucks, construction equipment and other heavy-duty machines increases, the Group is expanding its activities beyond vehicles and components to include energy storage and related services.

The planned energy park will provide a practical environment for testing how battery storage, grid flexibility and customer energy solutions can operate together at scale.

The Volvo Group drives prosperity through transport and infrastructure solutions, offering trucks, buses, construction equipment, power solutions for marine and industrial applications, financing and services that increase our customers’ uptime and productivity. Founded in 1927, the Volvo Group is committed to shaping the future landscape of sustainable transport and infrastructure solutions.
