The data centre boom meets the grid: Why Poland's AI gold rush will be decided at the oower connection - Prime East - Real Estate Investment and Development Boutique

No segment of Europe’s real estate market is growing faster in 2026 than data centres and few locations benefit more than Poland. Yet as hyperscalers commit billions and international investors queue up, the real question is shifting. The success of a data centre project depends less and less on the plot of land, and more and more on the power connection. Anyone investing in Polish data centres today is, in truth, buying one thing above all: megawatts.

The Boom: Poland Becomes Europe’s AI Location

Poland is the undisputed data centre leader in Central and Eastern Europe and already ranks sixth in Europe by number of facilities. Current operational capacity stands at roughly 173 MW but that is only the beginning. According to forecasts from CBRE and Poland’s industry association, capacity is set to rise to around 500 MW by 2030 and 1,200 MW by 2034.

The inflow of capital is enormous. In 2025 alone, more than USD 6 billion in hyperscaler and enterprise commitments to AI infrastructure flowed into Poland. In February 2025, Microsoft announced an investment of PLN 2.8 billion (around USD 700 million) to expand its cloud and AI capacity the country’s largest hyperscaler project to date, accompanied by a cybersecurity programme with the Polish Armed Forces. Its “Poland Central” cloud region near Warsaw has been live since 2023. Google has operated a Warsaw cloud region since 2021 and signed a strategic AI partnership with Prime Minister Tusk and state institutions in February 2025.

One key driver comes, paradoxically, from the West. According to Colliers’ EMEA Data Center Markets Report H1 2026, energy and grid constraints in the established metros (Frankfurt, London, Amsterdam, Paris, Dublin) are redirecting capital to new locations with Poland at the front. Nearshoring, AI demand and the drive for digital sovereignty add further tailwind.

The Bottleneck: The Grid Cannot Keep Pace With Demand

This is exactly where the catch lies. In the classic European hubs, new facilities wait an average of seven to ten years for a grid connection up to 13 years in the most congested markets. The reason is simple: power demand is exploding. European data centres consumed around 96 TWh of electricity in 2024; that figure is expected to reach 168 TWh by 2030 (+75%) and 236 TWh by 2035 a doubling in just over a decade. As early as 2023, data centres accounted for 33–42% of local electricity demand in Amsterdam, London and Frankfurt, and nearly 80% in Dublin.

Poland is no exception to this pattern. Warsaw faces an estimated grid deficit of 150–200 MW; a medium-voltage connection to the Warsaw grid can take a year and a half. Developers frequently have to co-finance substation upgrades between EUR 2 and 15 million depending on the site delaying commissioning by up to 18 months. Grid congestion cost Europe around EUR 4.3 billion in 2024. The consequence: by 2035, half of Europe’s data centre capacity is likely to be built outside the traditional hubs.

Poland’s Answer: 64 Billion Złoty for the Grid

The state is responding at scale. Transmission operator PSE is investing around PLN 64 billion (approx. USD 16 billion) in new high-voltage lines through 2034 some 4,800 to 5,000 km of new 400 kV routes. This is intended to let the network host around 3 GW of data centre capacity by 2035 and up to 5 GW by 2040. In parallel, the energy mix is being rebuilt: coal’s share of power generation is falling from 90% (2010) via 55% (2025) to a planned 20% by 2030. By 2030 Poland aims for 51% renewable electricity and 64 GW of renewable capacity, including around 6 GW of offshore wind feeding into the grid from 2026.

But the transition has friction. The connection queue now holds around 205 GW of renewable and storage projects three times today’s net grid capacity. Many are “ghost projects” that mainly block a coveted connection slot rather than getting built. And Polish industrial electricity prices were among the highest in the EU in 2024, on a par with German levels. Demand for connection capacity is plentiful the capacity itself is not.

What This Means for Investors

For the investment case, the decisive factor is shifting. No longer the land, but the secured power connection “powered land” becomes the scarce, value-defining asset. In concrete terms:

• Power before land: A firm connection agreement with substation capacity is now worth more than the plot itself. Due diligence starts at the grid, not the land registry.

• Early securing beats late scaling: Given multi-year queues, locking in connection rights early creates a structural advantage.

• Beyond Warsaw: Secondary locations with spare grid headroom for instance along the new PSE routes gain appeal over the congested capital.

• Take energy risk seriously: Power-price volatility, connection timelines and the risk of “stranded” projects belong in every realistic model.

It is precisely at this intersection of real estate, engineering and energy that Prime East’s core expertise lies. Through our specialist division PE Property Solutions, we support data centre projects across the full cycle from site and grid analysis through permitting to delivery.

Conclusion

Poland’s AI gold rush is real the hyperscalers’ capital commitments prove it. But the real bottleneck is neither demand nor capital; it is the power grid. For investors, the task is shifting from “find the right plot” to “secure the megawatts.” Those who make this shift in perspective early will be among the winners of the next cycle.
