Scotland told to fix grid rules, not freeze data centres – Aurora
Grid bottlenecks not demand are the binding constraint, consultancy warns Scottish government.
Aurora Energy Research told Scottish policymakers on Tuesday (2026-07-14) that freezing data centre connections would leave the underlying constraint in place: a grid connection queue blocked by outdated rules, not a surge in power demand.1
The consultancy's intervention comes as regulators across Europe grapple with how to handle the data centre boom without breaking local grids. Scotland is one of several European regions where the gap between connection requests and available capacity has widened sharply.3
In Germany, where grid operator queues have swelled to 500 GW of battery project applications alone, the first-come, first-served rule for hook-ups has encouraged speculative filings far beyond serious demand. Aurora's argument is that Scotland faces a similar structural problem, not a demand emergency.3
The top five European data centre hubs — Frankfurt, London, Amsterdam, Paris and Dublin — currently account for over 5 GW of combined demand capacity. Scottish data centre demand is a fraction of that, but the connection queue has lengthened as developers race to secure grid access before rules tighten.1
Aurora's analysis suggests that reforming connection rules, not capping new demand, would unlock more capacity for renewable generation and storage while still accommodating data centre growth. The consultancy pointed to Sweden, where energy minister Ebba Busch paused interconnector projects to other EU states last week (week of 2026-05-04), including a 1 GW link, to address domestic grid constraints.4
That Swedish decision underscores a broader pattern. Italy's data centre boom risks grid bottlenecks by 2030, with power demand set to quadruple to 20 TWh, according to consultancy Key to Energy. Spain and eastern Europe could capture investment if Italy's grid fails to keep pace.5
European grid operators are already spending heavily. Italy's Terna is investing €18bn ($21bn) in 2024-28. France's RTE plans €100bn between 2025 and 2040. TenneT, the sole TSO in the Netherlands and the biggest in Germany, has committed €200bn by 2034. ENTSO-E estimates €800bn is needed for EU electrification goals by 2050.3
Yet the challenge for Scotland and other smaller markets is that connection queue backlogs, not total investment, are what slow capacity build. Developers can wait years for a grid study, and speculative applications crowd out viable projects. Aurora argues that queue reform, not a moratorium, is the cheaper, faster fix.3
Germany's numbers make the distortion plain. In that country, 500 GW of battery projects have applied for connections — more than 20 times current capacity — and not all are serious. The first-come, first-served rule encourages speculation. Scotland risks the same dynamic if it freezes connections without fixing the queue mechanics.3
Data centre demand is growing fastest in emerging markets, where Wood Mackenzie projects compound annual growth rates above 5% for China, India and Southeast Asia. In Europe, only Ireland stands out, with data centres using over 20% of national power. For most European markets, the grid rule problem dwarfs the demand problem.2
Scottish policymakers now face a choice between Sweden's path of pausing interconnector capacity and Aurora's path of queue reform. The decision will affect not just data centre developers but wind and storage projects waiting behind them in the same queue.4
