STRABAG AG has been commissioned to create the necessary infrastructure for the Waltrop Battery Park. This undertaking, initiated by Trianel Batteriepark Waltrop GmbH & Co. KG (TBW), is one of the most significant battery storage projects in Germany. With a planned output of approximately 900 MW and a storage capacity of around 1,800 MWh, it is designed to make a substantial contribution to grid stabilisation, bottleneck management, and the flexibilisation of the electricity market. The operational commissioning of the complex is scheduled for the second half of 2028.
The development is taking on a more concrete form with the ground-breaking ceremony, which took place on 21 September 2026. Manuel Eck, Managing Director of Trianel Batteriepark Waltrop GmbH & Co. KG, stated that the Waltrop Battery Park represents central infrastructure for the upcoming phase of the energy transition and that the plans are now being transformed into visible reality.
Scope of STRABAG's services
STRABAG is responsible for the complete development of the entire site, thereby creating the essential conditions for the construction and subsequent operation of the battery storage park. This includes the turnkey realisation of the associated buildings of the 380 kV substation as well as the provision of all necessary infrastructural elements for its construction and functionality. Thomas Nyhsen, a member of the Executive Board of STRABAG AG, emphasised that large-scale battery storage systems form a fundamental component for a sustainable energy system and that the required infrastructure serves as the basis for their successful and long-term operation. He highlighted that STRABAG is contributing its expertise to the large-scale battery storage park in Waltrop and supporting the expansion of a future-oriented energy infrastructure.
Challenges of construction logistics
The specific project location within the harbour environment places particular demands on construction logistics. During the construction phase, the accessibility of a pipeline crossing the site must be continuously ensured. Additionally, ongoing harbour activities, the use of infrastructure for heavy transports, and keeping the mast locations of existing high-voltage lines clear must be considered in the planning. Existing groundwater monitoring points will also be comprehensively integrated into the construction processes to ensure precise implementation.
