Traunstein, 20.01.2026
- PV projects with on-site PPAs and battery storage: Rheinmetall and Energy Partners are implementing photovoltaic and battery energy storage (BESS) projects at various locations in Germany, including on-site power purchase agreements (PPAs), in which the electricity generated is used directly on site.
- Start of construction of the first project in Neuss (North Rhine-Westphalia): The first PV project will start in early 2026 in Neuss and comprises a 1.5 MW rooftop system, the signing of an on-site PPA and the installation of a battery storage system with a capacity of more than 1 MWh.
- Contribution to climate and resilience goals: The projects support Rheinmetall's CO₂ reduction strategies and increase its self-sufficiency.
As a leading international systems provider for the defence industry and a driver of forward-looking technological developments, Rheinmetall pursues efficient, sustainable and cost-effective energy procurement and relies on a strategic partnership with Energy Partners GmbH from Traunstein. Rheinmetall and Energy Partners are planning a total of over 20 megawatts (MW) of PV capacity at various locations, supplemented by battery storage systems with a capacity of more than 10 MWh. The PV systems include rooftop installations, ground-mounted systems and innovative PV carports, which address the growing need for flexibility and optimisation of self-consumption. The systems will be supplemented by high-performance battery storage systems, which are becoming increasingly essential for stability and economic efficiency. The first joint project is being developed at the Neuss site (North Rhine-Westphalia). There, a 1.5 MW PV system with on-site PPA and battery storage will be implemented. Construction is scheduled to start in Q1 2026, with completion planned for Q2 2026.
All projects rely on durable components and favour suppliers from Europe and the region in order to shorten supply chains, ensure quality and guarantee long-term system availability. "Energy Partners is a reliable partner for us, one that understands our requirements and confidently tackles the technical challenges at our various locations. Whether photovoltaics, battery storage systems or PV carports – Energy Partners can deal flexibly with different energy systems and contact persons. The open communication and solution-oriented approach are particularly valuable, making the collaboration efficient and pleasant. In this way, we are laying the foundation for a sustainable energy supply together," says Roland Preisler, Senior Vice President Strategic Energy Procurement at Rheinmetall.
Matthias Giller, Managing Director of Energy Partners GmbH, is also delighted: "We are proud to have gained such an important partner in Rheinmetall, a leading company in the field of European defence. This collaboration is another milestone on our journey to provide industrial customers in Germany with innovative, sustainable energy solutions. Together, we are committed to a future-oriented and sustainable energy supply that not only covers ecological and safety aspects, but also offers economic advantages for our partner. The combination of battery storage and photovoltaics has become the absolute standard."
Energy Partners GmbH, a subsidiary of MaxSolar GmbH, implements the projects independently and ensures fast and efficient implementation throughout Germany. In close cooperation with Rheinmetall, the joint goal is to equip company locations with tailor-made, sustainable energy solutions that offer both ecological and economic advantages. The focus is on the efficient use of renewable energies to reduce operating costs and increase independence from external energy sources.
