WBS Power sells Germany’s largest PV and BESS co-location project to Prime Capital - Hyperscale data center planned
Frankfurt am Main (Germany) - WBS Power is selling Germany’s largest combined battery and solar project to Prime Capital. The initiative is an impressive example of the rapid implementation of scalable energy infrastructure, linking renewable power generation with digital infrastructure while addressing the high energy demands of modern data centers.
Germany’s largest PV and BESS project changes ownership
WBS Power GmbH has sold the pioneering “Project Jupiter” to Prime Capital AG. The transaction is structured through the specially established Luxembourg company Jupiter JVCo S.à r.l. and is contingent on the project reaching ready-to-build status. With 500 MW of storage power, 2,000 MWh of storage capacity, and 150 MWp of solar power, it is Germany’s largest combined photovoltaic and battery storage project to date.
The site is located on a former military airfield in Brandenburg. Construction of the project, with an expected investment volume of €500 million, is scheduled to begin at the end of 2026 or early 2027. Both the BESS and PV systems will feed into the 50Hertz 380 kV high-voltage line via a shared grid connection. To avoid delays, critical components such as transformers will be procured early.
Maciej Marcjanik, CEO of the WBS Power Group, emphasized: “Project Jupiter demonstrates our commitment to innovation and scale. By integrating Germany’s largest co-located BESS and Solar PV project with a hyperscale data center, we are creating a unique platform that supports both the energy transition and digital transformation.”
Dr. Mathias Bimberg, Head of Infrastructure at Prime Capital, added: “This acquisition strengthens the country’s critical infrastructure by combining renewable energy and digital capacity at an unprecedented scale. Project Jupiter is a cornerstone for a resilient, sustainable, and future-proof energy system. It also marks a pivotal step in executing our fund’s strategy to invest in transformative assets that drive the energy transition in Europe.”
The transaction was exclusively advised on the sell-side by PwC and the M&A and project finance consultancy Capcora. WBS Power was legally advised by CMS and Prime Capital by DLA Piper, with technical consulting provided by Fichtner.
Andrzej Rusniak from PwC Poland commented: “This transaction exemplifies how strategic partnerships can accelerate the energy transition while creating long-term value.” Alexander Enrique Kuhn from Capcora added: “Bringing together two like-minded investors is critical to the success of a project of this magnitude and importance. With initiatives like Project Jupiter, we are making a tangible contribution to Germany’s energy transition.”
Joint venture for hyperscale data center at the same site
In parallel with the sale, a joint venture was established to develop a hyperscale data center on the site with a planned capacity of 500 MW. The location, with its robust 380 kV connection, offers ideal conditions for integrating self-consumption capacities and directly meeting the enormous energy demand of such facilities with renewable power.
The combination of battery and solar projects with data centers is gaining importance as digital infrastructure in Germany grows rapidly. Direct access to renewable energy and stable grid capacity reduces dependence on conventional power plants and enhances supply security.
With the sale, WBS Power is advancing its strategy of developing projects along the entire value chain - from BESS and solar to onshore wind and hyperscale data centers - both in Germany and in Poland.
