Grid reform starts with connections, but delivery depends on manufacturing capacity and supply chains.
Ofgem’s proposal to introduce commitment fees for large data centre projects has put Britain’s grid connection queue under fresh scrutiny. The regulator wants developers to provide financial security when accepting a connection offer and meet clearer project milestones. Projects that progress would have the fee returned at energisation. Those that fail to move forward could lose it.
The consultation, launched on 29 July 2026, is designed to remove speculative or non-viable projects from the queue and give credible developments a clearer route to grid access. Ofgem says 315 data centre projects are currently seeking connections, representing 73 GW of demand. That is significantly higher than Britain’s recent peak electricity demand.
The scale of the queue reflects the growth of artificial intelligence, cloud computing and digital services. But it also exposes a wider issue. Grid capacity cannot be treated as an unlimited reservation. Every stalled project can affect the timing of another industrial facility, housing development, hospital or infrastructure scheme waiting for power.
Connection reform may improve how capacity is allocated, but queue management alone will not solve the delivery challenge.
Behind every viable connection sits a physical supply chain. Transformers, electrical steel, conductors, insulation systems, switchgear, monitoring equipment and skilled manufacturing capacity all determine how quickly new demand can be served. Network planning can set priorities, but factories must still produce the equipment required to turn those priorities into operational assets.
This is where the data centre debate becomes directly relevant to the electrical manufacturing industry.
Data centres place substantial and often concentrated loads on power networks. Serving them can require new substations, additional transformers, network reinforcement and stronger coordination between developers, transmission and distribution operators, OEMs and component suppliers. Clearer evidence that a project will proceed can also help manufacturers plan capacity, secure materials and reduce the risk created by uncertain demand forecasts.
For transformer manufacturers, the challenge is particularly acute. Order books are strong, lead times remain a concern and critical materials can be constrained. At the same time, network operators and major energy users need greater certainty on delivery, asset performance and total cost of ownership.
Earlier engagement across the value chain can improve specifications, support more repeatable designs and reduce avoidable delays.
The proposed commitment fee sends an important signal: access to grid capacity must be matched by delivery readiness.
For CWIEME Berlin, the bigger conversation is how the industry converts that readiness into real infrastructure. Bringing grid operators, transformer manufacturers, materials suppliers, machinery providers and technology specialists into the same room creates the conditions for practical progress. It allows the sector to address transformer availability, manufacturing bottlenecks, testing capacity and supply risk as connected issues, rather than separate problems.
That makes manufacturing readiness a central part of Britain’s response to industrial and digital power demand.
As electricity demand grows, successful grid reform will depend on more than deciding who moves forward in the queue. It will depend on whether the electrical manufacturing value chain can deliver the equipment, capacity and collaboration needed to connect them.
