A former military airfield in Brandenburg is about to become one of Europe’s most transformative clean-energy hubs. When Prime Capital announced its acquisition of the Jupiter BESS and solar project, it signalled more than a major infrastructure deal—it marked a bold step toward merging renewable generation with hyperscale data capacity. This blog unpacks the story behind the acquisition and why it represents a defining moment for the energy transition.

Prime Capital’s move to acquire the Jupiter BESS + solar project from WBS Power underscores its commitment to large-scale, future-ready energy infrastructure. Jupiter combines a 500 MW/2,000 MWh battery energy storage system with 150 MWp of solar PV, all situated on a 145-hectare site with a single 380 kV grid connection operated by 50Hertz. As the project advances toward ready-to-build status, the parties have already agreed to fast-track long-lead procurement to secure the earliest possible grid access. The $580.56 million initiative, financed through Prime Green Energy Infrastructure Fund II, positions Jupiter as one of Germany’s most critical upcoming clean-energy assets.

Alongside the acquisition, Prime Capital and its partners are laying the foundation for a hyperscale data centre with a planned capacity of 500 MW. What makes this venture extraordinary is its direct integration with the Jupiter project’s renewable output, enabling unprecedented levels of energy efficiency, grid stability and operational resilience. This synergy between digital infrastructure and clean-energy generation reflects an accelerating global trend—data-intensive industries seeking sustainable, on-site power solutions that reduce carbon footprints while enhancing performance.

Beyond its scale, the acquisition symbolizes a strategic milestone: the seamless pairing of Germany’s largest co-located BESS and Solar PV project with a next-generation data centre. This model could become a blueprint for countries aiming to balance rising digital-economy demand with ambitious climate targets. With the sale process initially launched in March 2025 and guided by advisors including Capcora, PwC, CMS, KKMP, DLA Piper and Fichtner, the collaboration demonstrates how coordinated expertise can accelerate innovative energy solutions. As construction is slated for late 2026 to early 2027, Jupiter is set to reshape how energy and data ecosystems coexist.

Prime Capital’s Jupiter acquisition does more than strengthen renewable infrastructure—it showcases how transformative assets can power the digital world sustainably.
