en.Wedoany.com Reported - Policymakers and regulators must adjust the energy market framework to transform data centers from a burden on the grid into flexible system assets. As electrification of transportation, heating, and industry accelerates, along with large-scale integration of renewable energy, Europe's power grid is under unprecedented pressure, and the sharp increase in data center electricity demand further exacerbates this challenge. It is estimated that by 2030, Europe's data centers will require 161 terawatt-hours of electricity, a 127% increase from 2024.
The grid infrastructure in many European countries is aging, with a severe backlog of grid connection applications for large-scale renewable energy projects. According to conservative estimates, approximately 1,700 gigawatts of renewable energy projects are awaiting grid connection in just 16 European countries. In Ireland, data centers already account for about one-fifth of the country's total electricity consumption, according to Ireland's Central Statistics Office. In hub cities such as Dublin, Amsterdam, Frankfurt, and London, the queue time for new hyperscale data center projects to connect to constrained grids could exceed ten years. The UK's Office of Gas and Electricity Markets (Ofgem) warns that the surge in demand connection applications has exceeded expectations, posing risks to strategic projects.
Analysis indicates that data centers are not only energy-intensive facilities but also possess highly controllable load characteristics due to their built-in advanced digital management systems and backup power infrastructure, creating conditions for providing grid flexibility. According to LCP Delta, the balancing costs of European transmission system operators for ancillary services reached approximately €6 billion in 2025. If data centers can provide demand-side flexibility, their roles could include: reducing demand during grid stress to alleviate congestion, participating in ancillary service markets to maintain system stability, accepting non-firm connections to utilize off-peak idle capacity, and adjusting consumption based on renewable energy generation patterns to absorb surplus wind and solar power.
Some European countries have begun experimenting with relevant policies. Irish regulators require large data centers to provide on-site generation or storage capacity matching their electricity demand and to feed power back to the grid during system stress. In a trial by the UK's National Grid, data centers demonstrated the ability to reduce load by 30% within approximately 30 seconds to maintain resilience. It is estimated that by 2030, the 6 gigawatts of data centers deployed in the UK could provide over 2 gigawatts of capacity to the grid when needed.
In the Netherlands, regulator ACM has excluded data centers from the list of projects aimed at alleviating grid congestion, reflecting that the potential of flexible demand has not yet been fully recognized in policy. Industry experts believe that unlocking this potential requires closer collaboration between network operators, regulators, and the digital infrastructure sector. Through connection reforms, proof-of-concept pilots, and sustainability-related incentives, the flexibility of data centers can transition from theory to commercial application.
