Chris Pennington, Director of Energy & Sustainability at Iron Mountain Data Centers, explains why a more collaborative approach to grid integration will be essential to supporting Europe’s digital growth.

Europe’s digital ambitions are growing rapidly. AI, cloud computing and the wider digital economy all depend on continued investment in data centre infrastructure. At the same time, Europe is modernising its electricity networks and pursuing ambitious decarbonisation targets.

These developments are often presented as competing priorities, particularly as grid capacity becomes increasingly constrained. In reality, they are becoming more closely connected. The challenge now is ensuring that digital infrastructure and energy infrastructure evolve together. That requires a different way of thinking about how data centres interact with the grid.

The recent Declaration of Intent on the sustainable integration of data centres into the EU energy system reflects this shift. Signed by 14 European industry associations, including the European Data Centre Association (EUDCA), with support from the European Commission, it recognises that supporting Europe’s digital future will require closer cooperation across the energy ecosystem.

Move beyond a ‘plug-and-play’ mindset

For many years, connecting a data centre to the electricity network has largely been viewed as a straightforward process. A facility secured a grid connection and drew the power it needed to operate. As demand for digital infrastructure continues to accelerate, that approach is becoming increasingly difficult to sustain.

Electrification across many sectors and continued AI adoption are placing even more pressure on Europe’s electricity networks. Looking at data centres purely through the lens of energy consumption no longer reflects the role they can play within the wider system.

Instead, there is an opportunity to think differently about how data centres interact with the grid. Data centre operators should be part of discussions about energy resilience and affordability, working alongside grid operators and policymakers to support a more balanced electricity system.

Changing that mindset is an important first step because it shifts the discussion away from capacity constraints alone towards how infrastructure can be planned and utilised more effectively.

Create space to test new approaches

One of the biggest challenges facing Europe is finding opportunities to trial new ideas. European energy regulation has traditionally followed a structured and cautious approach, providing consistency across the sector. However, that can also make it difficult for new models to move beyond discussion and into practical application.

Compared with North America and parts of Asia-Pacific, Europe has generally moved more slowly when it comes to exploring different approaches to grid integration. If the industry is to respond to growing demand, there needs to be greater willingness to test new solutions within an appropriate regulatory framework.

This does not mean abandoning high standards or reducing oversight. We need to create opportunities to learn what works before today’s challenges become tomorrow’s constraints. Enabling residential energy ‘prosumers’ through plug-in solar and aggregating distributed energy resources into virtual power plants are examples of innovations that fundamentally reshape the existing utility paradigm.

Progress has rarely come from relying entirely on established processes. The next phase of Europe’s digital growth will require the confidence to explore new ways of working across the energy sector.

Turning collaboration into delivery

One of the most significant aspects of the declaration is its emphasis on implementation. It provides for ad hoc working groups to examine issues including grid flexibility, energy generation and storage. Those discussions could provide a practical forum for industry stakeholders to work through challenges together.

That collaborative approach matters because no single organisation can solve Europe’s grid challenges in isolation. Unlocking additional capacity will depend on organisations sharing expertise much earlier in the planning process and developing solutions collectively. Many of the innovations being explored today share a common element: greater distribution of resources and wider participation.

The next five to seven years will be particularly important. Decisions made during this period will influence how Europe accommodates continued digital growth while maintaining a resilient energy system.

The opportunity ahead lies in moving from reactive cooperation to proactive design. Instead of responding to grid constraints after they emerge, the sector has an opportunity to build stronger coordination into the planning process from the outset.

Keeping Europe’s digital and energy transitions aligned

Demand for AI and cloud computing is continuing to grow, making further investment in Europe’s digital infrastructure unavoidable.

Supporting that growth does not depend solely on adding more generating capacity or building more grid connections. It also depends on bringing together the organisations responsible for digital infrastructure, electricity networks and public policy so they can plan for the future collectively.

The Declaration of Intent offers a framework for those conversations. Its long-term success, however, will be measured by whether it encourages practical collaboration and gives the industry confidence to test approaches that better support both energy resilience and digital growth.

Europe’s digital and green transitions are often discussed as separate challenges, but they are becoming increasingly interconnected. Recognising that relationship creates an opportunity to plan infrastructure differently, strengthen cooperation across the sector and build an energy system capable of supporting the next generation of digital investment.
