ABO Energy and Field commission stand-alone storage facility in Waldkappel

(Wiesbaden, 11 March 2026) After about eight months of construction, ABO Energy and Field recently commissioned the German battery park in Waldkappel, Hesse. ABO Energy sold the facility in the second quarter of 2025 to Field, a London-based renewable energy infrastructure company operating across Europe, before construction began. Field operates battery storage facilities in several European markets and is currently establishing a cross-border platform for flexible energy systems.

The plant has an output of 16 megawatts and a capacity of over 33 megawatt hours, enabling it to store as much electricity as almost 10,000 two-person households consume in one night. It is already the fourth stand-alone storage project that ABO Energy has implemented in Germany - and the first that can deliver full power for over two hours. Another special feature is that the system components are not housed in shipping containers as is usually the case, but in modular racks mounted on a steel frame. This design meant that the racks could be delivered to the construction site pre-assembled, which significantly reduced the installation time on site. In addition, each rack is equipped with its own thermal management and protection system.

Battery storage systems are an important component of a secure, climate-friendly and independent energy supply. They stabilise the grid frequency by providing Frequency Containment Reserve (FCR), participating in intraday trading and feeding energy into the grid at peak load times. In this way, they help to balance fluctuations in electricity generation from renewable sources.

Field is a Europe-wide developer and operator of battery storage systems with projects in several core markets and is currently establishing a powerful, cross-border platform for flexible energy infrastructure. ABO Energy has many years of experience and comprehensive expertise in successfully implementing battery storage projects from development and planning to procurement and construction - including turnkey solutions on request.

"This enables us to create attractive investment opportunities for energy suppliers and funds, because we are convinced that private investment is a key lever for a sustainable and independent energy future in Europe," says Joachim Hundt, ABO Energy's Head of Cooperations in Financing & Sales. "Both companies have the same overarching goal: an energy transition to 100 per cent renewables. This shared mission was evident in the discussions from the very beginning." ABO Energy will take over the technical management of the plant for Field.

"Waldkappel is our first German project and a strong example of how quickly and reliably modern battery storage systems can be implemented today," says Field General Manager Philip Hainbach. "I would like to express my sincere thanks to everyone involved for their great work. For Field, Waldkappel is an important step in building-out our German portfolio." Luke Gibson, COO of Field, also emphasises the strategic importance of the project: "Waldkappel is an important milestone in executing Field's strategy in Germany and advancing our wider European flexibility platform. As our first asset in Germany, it marks the start of a broader build-out focused on high-quality, TSO-connected projects in locations of clear system need - forming the foundation of a flexibility portfolio that will strengthen energy security, enhance system resilience and renewable integration, and ultimately reduce costs for end consumers."
