WBS Power is developing the Baltic Data Center Campus, a hyperscale data center project in Lublewo, in the municipality of Choczewo in Poland’s Pomerania region, with a target capacity of 3.2 GW. The company says it has already secured grid connection conditions for the full 3.2 GW.
The plan is to build the campus in four phases, each sized at 800 MW. WBS Power describes its role as designing, integrating, and delivering the energy infrastructure intended to support AI, HPC, and cloud workloads.
Power architecture and buildout plan
Each 800 MW phase is expected to include dedicated energy infrastructure for AI workloads, integration with renewable energy sources, and battery energy storage systems (BESS). WBS Power also says the phases are planned to meet ESG, energy efficiency, and energy security standards, and to support cooperation with hyperscalers and cloud providers.
The campus is planned near “one of the largest power substations in Poland.” WBS Power says power supplied to the site will come from conventional sources complemented by renewable energy, and “in the longer term,” also nuclear power.
For data center engineers, the headline number here is the scale: 800 MW building blocks are far beyond typical facility planning cycles, and they shift the center of gravity from mechanical and IT design to power system design, grid integration, and staged commissioning. And with BESS called out per phase, the obvious operational question will be how storage is used in practice—peak shaving, backup, grid services, or some combination—because each path changes both design requirements and operating constraints.
Timeline and related projects
WBS Power expects preparatory work for all four phases to be completed by the end of 2027, with the first data center planned to become operational around 2028–2029.
“This will be the largest project of its kind in Poland and one of the largest in Europe,” said Maciej Marcjanik, CEO of WBS Power. CFO Hubert Bojdo added, “We are building the infrastructure that will underpin the next phase of the global digital transformation.”
WBS Power also points to another hyperscale effort, the Finsterwalde Data Center project in Germany, with a stated capacity of 500 MW.
