Artificial intelligence is beginning to reshape Poland’s energy debate. The expansion of data centres means that digital investment increasingly depends on something very physical: access to large volumes of reliable electricity. For the Polish power system, the challenge is not simply to produce more energy, but to connect new high-demand users while the grid is simultaneously being rebuilt for offshore wind, renewables, storage and future nuclear generation.
Data centres have become one of the fastest-growing sources of electricity demand globally. AI workloads are particularly energy-intensive because they require large clusters of processors operating continuously, together with cooling systems and extensive backup infrastructure.
From the perspective of a transmission or distribution operator, a large data centre therefore looks more like a new industrial plant than an office building. It may require a dedicated substation, stronger transmission links and connection work that takes years to plan and deliver.
Poland is already preparing for a much larger electricity system
Polskie Sieci Elektroenergetyczne, Poland’s transmission system operator, has one of the largest grid investment programmes in the country’s history. Its development plan for 2025–2034, with an outlook to 2037, includes 389 transmission projects with planned expenditure of around PLN 66.3 billion.
The programme includes thousands of kilometres of new high-voltage infrastructure and HVDC projects intended to strengthen the north-south transfer of electricity. That direction is increasingly important because much of Poland’s future large-scale generation, particularly offshore wind, will be located in the north, while a substantial share of industrial demand remains further south.
The growth of data centres adds another layer to this transformation. New facilities will compete for connection capacity with industrial plants, battery storage projects and other large users at the same time that renewable generators are also seeking access to the network.
Connection capacity may decide where projects are built
Data-centre location decisions used to be discussed mainly in terms of land, fibre connectivity, taxes and proximity to large markets. Electricity is now becoming one of the most important criteria.
For investors, the key question is increasingly not only how much power costs, but whether sufficient capacity can be guaranteed at a particular site and how quickly a connection can be delivered. In a constrained region, cheap land can lose its advantage if the grid cannot support another very large user.
This could gradually reshape Poland’s investment map. Locations close to strong transmission infrastructure or future generation capacity may become more attractive, while areas with limited grid headroom may struggle even if they offer favourable real-estate costs.
AI joins renewables, storage and electrification in the same queue
The timing is challenging because data-centre demand is arriving during a broader electrification of the economy. Poland is expanding renewable generation, preparing offshore wind projects, investing in storage and planning large changes in conventional and nuclear generation.
Each part of this transition needs network investment. Renewable projects need connections to inject electricity. Data centres need stable capacity to consume it. Storage can operate as both a producer and a consumer depending on market conditions. The grid therefore has to become more flexible, not simply larger.
Industry executives point out that data centres are not technically a separate category from other large connections. What makes them unusual is the speed at which investment plans are growing and their very high reliability requirements. Infrastructure supporting cloud services and AI cannot easily tolerate unstable supply.
The opportunity reaches beyond the electricity bill
For Poland, a larger data-centre market could also create demand for grid contractors, engineering firms, transformer suppliers, construction groups, cooling-system providers and energy-storage developers.
At the same time, the sector could intensify competition for electricity and connection capacity. If investment in the grid falls behind, Poland may face a situation in which investor demand exists but projects cannot be connected quickly enough.
The ability to attract the next generation of digital infrastructure may therefore depend as much on transmission planning as on technology policy. In the AI era, power infrastructure is becoming part of the digital economy’s competitive advantage.
