Anthony Canipa, VP of Customer Success at XYZ Reality, explains why the UK’s real grid challenge is not just rising data centre demand, but separating credible projects from speculative capacity.
It goes without saying that demand for the UK’s data centre sector is sky-high – the wave of current data centre proposals is unprecedented. However, a significant proportion is unlikely to progress to operational facilities.
That’s the reality behind today’s debate around power consumption and whether the grid can support the next phase of AI-driven infrastructure. Too much of the narrative assumes that everything in the queue will materialise.
It won’t.
As Data Centre Review’s Managing Editor, Jordan O’Brien, touched on in this recent article, the issue is not just the scale of demand – it’s the credibility of what sits within it. A significant proportion of proposed capacity remains speculative, with many projects unlikely to progress beyond early-stage planning. There is certainly some political grandstanding happening, and aspirational construction has long affected the sector.
Even with this in mind, there is a gap between speculative development and operational delivery in the UK. Let’s consider the reasons for this gap and what it really means for the sector.
The data centre queue only reflects intent
Currently, the UK’s grid allocation is based on projected capacity requirements, which, in theory, should enable long-term planning. Whilst this does ring true, it has also, in practice, created a queue that shows intent rather than actual execution of data centre development.
The connection queue exceeded 700 GW of requested capacity back in December 2025, stacked with speculative projects that might never reach completion. It’s a system that has created a bottleneck:
- Capacity is being reserved for doomed projects
- Delivery-ready developments are being forced to hit the brakes
- Timelines for grid connections can stretch back years, even decades
Between grid capacity constraints and lengthy connection timelines, far fewer facilities are coming online than were originally proposed.
Visibility into real progress is the missing layer
Even once the physical structure is in place, a project still has to move through multiple stages before it becomes a functioning data centre.
These stages separate the good and great projects from the ugly and delayed, but this level of distinction isn’t immediately visible in the grid queue.
Without a clear layer of transparency, grid operators are effectively stumped.
This is why the current model is under pressure. We’re already seeing action from Ofgem and NESO, which are aiming to move away from the grid queue’s first-come, first-served model in favour of projects that are further developed. Data centres are a pressure point within this reform agenda. They’re critical to the UK’s digital economy, but also among the largest and most complex sources of demand entering an already congested grid queue.
The effectiveness of reform will depend on how ‘readiness’ is defined. If it continues to rely primarily on projected milestones or application data, there is a risk that the system continues to prioritise intent over execution.
Delivery-based signals
Visibility into project development needs to reflect real progress, not just projected milestones. That means looking at signals such as:
- Evidence of engineering validation
- Demonstrated site activity
- Procurement and supply chain engagement
- Accuracy between projected timelines and confirmed progress
For developers, contractors and grid stakeholders, the challenge is not just knowing what has been promised. It is knowing whether delivery is tracking against the plan.
Incorporating these signals would allow the grid queue to evolve from a static list into a dynamic system – one that prioritises projects based on credible delivery pathways.
Economic impact
Projects that advance the UK’s economic position need to be prioritised. They are beneficial for society in the long term and deliver productivity gains. Bolstering digital infrastructure and AI sector growth will be a major component of the economy over the coming years, with benefits that compound over time.
By extension, which projects will create meaningful employment, workforce efficiency and supply chain activity? Which can be activated and contribute to the economy sooner?
Speed-to-delivery
Building on that, the difference between a project that becomes operational in two years versus 10 is significant. Faster delivery through more effective construction means faster infrastructure support and a lower risk of projects becoming redundant before launch.
By incorporating delivery-based signals into the grid queue, projects with credible timelines can be better prioritised.
Power efficiency
With the UK’s limited grid capacity, we must consider who uses power most effectively. Construction inefficiencies, particularly rework, can significantly delay project go-live and power-on timelines.
In complex data centre builds, even relatively small coordination issues can create knock-on effects across commissioning, infrastructure readiness and operational timelines.
Every delay extends the period between securing grid capacity and converting that capacity into productive digital infrastructure. Projects that demonstrate strong coordination and efficient delivery are therefore far more likely to generate value from the power they secure.
Every delayed project wastes time and postpones the moment when power becomes productive.
Closing the gap
The projects that will underpin AI, cloud and the next phase of digital growth are already identifiable. But they are stuck. Beyond AI and cloud, these data centres will increasingly support critical services ranging from financial systems to healthcare.
A power allocation system that cannot clearly distinguish between what is real and what is speculative helps no one. Change is on the horizon, but the next phase must go further. The system must prioritise delivery, not just demand. Execution, not just intent.
For those serving our industry with power, that means looking beyond the queue’s size and asking deeper questions. Which projects are progressing? Which have credible timelines? Which are already creating the conditions for construction, commissioning and long-term operation? Those are the questions that should shape how limited grid capacity is allocated.
The UK’s ability to compete on the global stage will depend on how effectively it uses its power.
