WBS Power GmbH has sold its “Project Jupiter” in Germany to Prime Capital AG, acting for its Prime Green Energy Infrastructure Fund II S.A., SICAV-RAIF, and formed a joint venture to co-locate a 500 MW hyperscale data center on the same site.
Project Jupiter comprises a 500 MW / 2,000 MWh Battery Energy Storage System (BESS) and up to 150 MWp of Solar PV on a former airfield, making it one of Germany’s largest planned co-located BESS and Solar PV projects.
According to a press release, both assets will use a shared grid connection to the 380 kV line operated by 50Hertz, with procurement of long-lead items such as transformers accelerated to secure the earliest connection date. The acquisition, executed via Jupiter JVCo S.à r.l. in Luxembourg, remains subject to the project reaching ready-to-build status.
Maciej Marcjanik, WBS Power Group, CEO, said, “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.”
Dr Mathias Bimberg, Prime Capital Head of Infrastructure, said, “This acquisition strengthens the country’s critical infrastructure by combining renewable energy and digital capacity at an unprecedented scale.”
The project reflects rising demand in Germany for data centers co-located with energy assets. WBS Power activity in Germany and Poland continues to build a portfolio of BESS, solar PV, wind, and data center developments.
Prime Capital plans to leverage the site’s strong grid connection to integrate on-site consumption and develop the planned data center. Located on a former military airfield in Brandenburg, Project Jupiter represents an expected € 500 million (US$ 582 million) investment, with construction targeted for late 2026 or early 2027.
