European renewable energy developer WBS Power has established a joint venture with Prime Capital to construct a 500MW hyperscale data center at a former military airfield in Brandenburg, Germany.

The data center will be colocated with Project Jupiter, a solar and battery energy storage project (BESS) currently under development at the same site.

Acquired by WBS Power in 2022, the asset will be sold to Prime Capital as part of the agreement, acting on behalf of its Prime Green Energy Infrastructure Fund II.

The project includes a 500MW/2,000MWh BESS and up to 150MW of solar, with construction slated to begin in late 2026 or early 2027. The project’s total cost has been estimated at €500 million ($583.2m).

According to the companies, the BESS and solar components of the project will share a single grid connection to a 380kV high-voltage line operated by transmission system operator 50Hertz.

The companies claim that the grid connection played a key role in their decision to develop a data center at the site. Timelines for the data center’s construction have not been shared.

“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. This project is a key milestone in our strategy to deliver next-generation infrastructure that combines renewable energy with digital capacity, reinforcing our leadership in sustainable development,” said Maciej Marcjanik, CEO of WBS Power Group.

WBS Power is a spin-off of the Polish company PST Solartechnik. According to its website, the company’s expansion plans cover data centers, electric vehicle charging stations, logistics parks, and hydrogen installations.
