Poland Has Three Years for Grid Connection, Western Europe Up to Thirteen

Companies building data centers for AI workloads are now asking investors a different question than they were just two years ago. They no longer care solely about land prices or proximity to fiber optic lines, but about one thing: how many megawatts of power they can secure, and when the electricity will actually start flowing. In Western Europe, the answer increasingly is: not before a decade passes. Poland, thanks to a still relatively uncongested grid, currently offers a shorter queue, but analysts warn this advantage has an expiration date.

The source of the paradox

A data center building itself can be constructed in 18 to 24 months. What takes far longer, and what investors talk about less publicly, is obtaining grid connection terms and physically delivering the power. In Europe's largest hubs, this stage has become the main bottleneck for the entire industry, outpacing capital constraints or land availability.

Examples from Western Europe illustrate the scale of the problem. In Dublin, the Irish regulator suspended the issuing of new grid connection terms for data centers in 2021 due to excessive strain on the network from the sector. The moratorium was only formally lifted at the end of 2025, but many previously approved projects are still waiting for physical connection, leaving investments worth around 6 billion euros frozen. In Amsterdam, new large facilities have been effectively capped, and further applications are pushed into an indefinite future due to a lack of spare grid capacity.

Poland's window of opportunity

Against this backdrop, Poland looks favorable, and that is the main argument the industry now uses to attract investors looking for space for the next wave of AI server farms. The national grid is less congested than Western Europe's, so operators still have spare capacity to allocate. The market is responding with accelerated growth: total installed data center capacity in Poland is projected to rise from 660 MW in 2025 to around 930 MW by 2030, with Warsaw, Poznań and Wrocław cementing their position as the main hubs of the Central and Eastern Europe region.

That advantage, however, is neither free nor permanent. In Warsaw itself, where most of the national market is concentrated, available connection capacity has shrunk by nearly 40 percent over two years, and operators such as PGE and Tauron are struggling to modernize the grid fast enough to keep pace with incoming applications. Polskie Sieci Elektroenergetyczne (Poland's electricity transmission system operator) has received connection applications totaling nearly 130 GW combined, though the industry cautions that some of these are purely speculative and will never be built.

Clients increasingly rarely ask only about price or geographic location. Above all, they ask when they can realistically get their infrastructure up and running.

Cooling as a lifeline instead of new connections

Since grid expansion cannot keep up with demand, the industry is looking for savings wherever it can, starting with the server room infrastructure itself. Traditional air cooling can consume up to 40 percent of the energy used by a facility, so more and more operators are switching to liquid cooling, which can remove 50-100 kW of heat from a single server rack, several times more than air-based solutions at comparable power consumption. The scale of interest in this technology is illustrated by Eaton's acquisition of Boyd Thermal, which has a manufacturing plant in Gliwice, for 9.5 billion dollars.

An additional argument for this shift is the potential for heat recovery. Water that absorbs heat from servers reaches temperatures of 50-60 degrees Celsius, making it usable in municipal district heating networks. This is changing how local governments and regulators view data centers, shifting them from a pure grid burden to a potential piece of local energy infrastructure, in line with the requirements of the EU's Energy Efficiency Directive (EED).

The risk of a Dublin repeat

Data centers currently account for around 4 percent of Poland's national electricity consumption, but forecasts project demand rising from 2 TWh to as much as 29 TWh annually by 2040, driven mainly by workloads tied to training and running AI models. Analysts warn bluntly that without parallel expansion of the transmission grid, renewable energy sources, energy storage and local microgrids, Poland could repeat Dublin's scenario within a few years: a sudden influx of projects followed by a regulator forced to freeze further connections.

For Polish companies and local governments, this means a concrete decision needs to be made faster than the usual pace of infrastructure investment would suggest. The shorter connection queue currently acts as a magnet for global capital looking for space for AI server farms, but on its own it is not a lasting competitive advantage, rather a delay of the same problem Western Europe is already grappling with.
