Grid changes across Europe
An examination of power grid capacity and power demand forecast to 2030 for cities such as London, Manchester, Paris, Lyon, Amsterdam, Berlin, Munich and Barcelona reveals some worrying trends.
A breakdown of what is happening shows some common issues around demand potentially outstripping capacity. The overall picture is one of uncertainty. Almost all metros will face constraints by 2030 if renewable expansion or flexible gas capacity is delayed.
This is leading to real supply risk with multi-year connection queues to access new generation in almost every large metro. Common factors include increased demand due to competition for connections and the rapid move to variable renewables with offshore wind and solar on the network set to rise materially by 2030.
Another commonality for AI Edge data centre developers is navigating reform of grid connection processes. The UK’s connection queue will move from a “first come, first connected” process to a “first ready and needed, first connected” system.
Ofgem says: “Industries of the future, ranging from data centres and AI to wind and solar projects, will be pushed to the front of the queue for grid connections.” (Source: Latham Watkins.) While this could be positive for some data centres, the competition will remain fierce.
In Amsterdam amid a strong push for more renewables and storage, analysts warn of supply risks after 2030. Here, the TSO’s 2030 plans for national grid upgrades and storage are crucial to avoid local curtailment or constrained connections which are a risk factor for data centres.
The situation is not so different in Frankfurt, Berlin and Munich where grid access is a bottleneck for data centre developers. In some German cities, grid connection requests are thought to exceed existing capacity by several gigawatts. Frankfurt’s “first come, first served” model is being reconsidered.
According to a Federal Network Agency report (2025), Germany faces potential stress points by 2030 under slower build-out scenarios with worst-case modelling suggesting tens of GW of additional capacity might be required to avoid disruption.
Berlin and Munich will benefit from national decarbonisation but may face local reinforcement needs and must rely on demand-side flexibility and storage to avoid local bottlenecks. Here as well as increased electricity demand, moves to renewables are creating the need for controllable capacity through on site generation, storage, demand response and dispatchable power.
Barcelona’s metropolitan demand growth requires distribution upgrades and grid reinforcements for large load demands of data centres and industry. The city has planned connection and grid enhancement projects through to 2030 but these require large transmission or substation works which take multiple years to build.
Even in cities such as Paris and Lyon which benefit from the firm base of France’s nuclear capacity, grid reinforcement can take years as the regional expansion of renewables grows rapidly.
Europe’s power industry is undergoing its greatest transformation since the world electrified in the late 19th and early 20th centuries, however it’s dependent on historic national energy strategies, grid reform, connection processes and decarbonisation – all moving at different speeds.
