Europe’s Data Centres Are Evolving From Power Consumers to Energy Partner

At the European Data Center Associations Summit hosted by Vertiv, industry leaders argued that AI growth is forcing data centres to rethink their relationship with power grids, communities and policymakers.

Data centres are increasingly being asked to do more than simply consume electricity and provide computing capacity. As AI drives unprecedented demand for digital infrastructure, industry leaders across Europe are beginning to position data centres as active participants in the wider energy ecosystem.

That was one of the central themes emerging from the European Data Center Associations Summit, hosted by Vertiv at Zagreb, where representatives from data-centre associations across Sweden, the Netherlands, France and Ireland discussed the infrastructure supporting Europe’s digital economy.

The conversation began with a reminder of how invisible data centres remain to most users. Consumers may interact with data-centre infrastructure dozens of times every day, through banking, digital payments, video calls, cloud applications and government services, without ever thinking about the physical systems behind those services.

But AI is making that infrastructure increasingly difficult to ignore.

From grid burden to grid participant

As data-centre demand expands, access to electricity has become one of the sector’s biggest constraints. Yet the panel argued that data centres should not necessarily be viewed purely as an additional burden on already stretched electricity networks.

Stijn Grove, Managing Director of the Dutch Data Center Association, pointed to the potential for data centres to locate closer to renewable-energy generation and absorb power that might otherwise require significant additional transmission infrastructure.

He also highlighted a broader opportunity: data centres could potentially help stabilise grids as renewable generation becomes more variable.

That idea was echoed by Ronan Kelly, CEO of Digital Infrastructure Ireland, who discussed the role of battery energy-storage systems and on-site backup capacity in supporting electricity networks during periods of peak demand.

The direction of travel is significant. Data centres are beginning to move from simply asking “How much power can the grid give us?” towards asking “How can our infrastructure interact with the grid?”

Waste heat becomes an asset

The panel also highlighted heat reuse as one of the clearest examples of how data centres can integrate more deeply into local communities.

Isabelle Kemlin, Vice Chair of the Board at Swedish Datacenter Industry, cited examples where waste heat from data centers is being reused through district-heating systems and even agricultural applications.

In the Netherlands, Grove pointed to projects where data-centre heat is being used to replace natural gas in buildings and potentially support greenhouse operations.

Such projects challenge the perception of data centres as isolated industrial buildings that simply consume electricity and generate heat. Increasingly, the heat itself can become part of another energy system.

AI changes the efficiency conversation

AI is also forcing the industry to reconsider how data center efficiency should be measured.

For example, equipment installed to recover and redistribute waste heat may consume additional electricity and therefore worsen a facility’s PUE, even though the overall energy system becomes more efficient.

The discussion therefore moved towards a newer metric increasingly associated with AI infrastructure: tokens per watt.

Instead of measuring only how efficiently a facility delivers electricity to IT equipment, tokens per watt attempts to connect energy consumption with the amount of useful AI computation produced.

As AI factories become larger and more power-intensive, the ability to convert electricity into useful compute efficiently may become as important as simply minimising facility overhead.

Europe’s sovereignty challenge

Energy is not the only reason Europe will continue to require significant local data center capacity.

The panel also highlighted digital sovereignty.

Europe’s fragmented national landscape means governments, public-sector organizations, and regulated industries frequently need to consider where data is stored and processed. Moving workloads across borders may be technically possible, but sovereignty, security, and latency requirements can make local infrastructure essential.

That creates a very different environment from markets where computing resources can be concentrated across a smaller number of enormous geographic regions.

The public-perception problem

Perhaps the industry’s biggest challenge, however, is not technical.

Several panellists acknowledged that public perceptions of data centers remain dominated by concerns around electricity consumption, water usage, land requirements and limited employment creation.

Michaël Reffay, Managing Director of France Datacenter, argued that many of these criticisms overlook the wider economic and digital services supported by data center infrastructure.

Kelly made a similar point, arguing that discussions about data-centre carbon emissions frequently focus only on the electricity consumed by facilities while ignoring emissions potentially avoided through digital services such as remote working, digital banking and electronic distribution.

The industry therefore faces a communication challenge alongside its engineering one.

Data centers will consume significant amounts of energy as AI expands. But the sector increasingly wants policymakers and the public to judge that consumption alongside the digital services, economic activity, renewable-energy investment, and wider infrastructure benefits it enables.

AI makes infrastructure strategic

Perhaps the clearest conclusion from the discussion was that digital infrastructure is no longer simply a back-end utility.

AI is making access to power, cooling, grids and computing capacity strategic economic issues.

For Europe, the next phase of the datacentre debate may therefore be less about whether more facilities should be built, and more about where they are built, how they interact with energy systems, and how effectively the industry can demonstrate their value to society.
