Data centre to be built near planned Polish nuclear power plant

Preparations for the project - named the Baltic Data Centre Campus - have taken several months, the company said, and included the development of the investment concept, the selection of an optimal location and the securing of suitable plot for the development. "The chosen site allows the project to scale flexibly across different technological configurations while ensuring access to sufficient power sources," it added.

WBS Power is now moving into the next phase of the project. The campus will be built in four phases, each with a planned capacity of 800 MW. Each phase will include: dedicated energy infrastructure for AI workloads; integration with renewable energy sources and battery energy storage systems; solutions meeting the highest ESG, energy efficiency and energy security standards; and platforms designed to support cooperation with global hyperscalers and cloud providers.

Preparatory work for all four phases is expected to be completed by the end of 2027, with the first data centre planned to become operational around 2028–2029.

The company said it has already secured grid connection conditions for the full 3.2 GW capacity.

"This will be the largest project of its kind in Poland and one of the largest in Europe," said WBS Power CEO Maciej Marcjanik. "The rapid development of AI is driving demand for hyperscale data centres supported by advanced infrastructure and reliable access to large volumes of power. The integration of renewable energy and energy storage with digital infrastructure will be a key pillar of competitiveness for next-generation hyperscale projects."

The company said power supplied to the Baltic Data Centre Campus "will come from conventional sources complemented by renewable energy and, in the longer term, also nuclear power".

In November 2022, the then Polish government selected Westinghouse AP1000 reactor technology for the construction of the country's first nuclear power plant at the Lubiatowo-Kopalino site in Choczewo municipality. The aim is for Poland's first AP1000 reactor to enter commercial operation in 2033.

"The digital revolution requires infrastructure on an entirely new scale," said WBS Power CFO Hubert Bojdo. "We selected the location for the Baltic Data Centre Campus very carefully, ensuring access to large power capacities, a diversified energy mix already in place today, and the long-term prospect of stable supply supported by future nuclear generation."
