- National Grid reports over 30 gigawatts of proposed data center connections awaiting access in England and Wales, equivalent to two-thirds of Great Britain’s peak electricity demand.
- Ofgem states that data center connection applications in the UK have tripled since late 2024, far exceeding forecasts, after the government classified data centers as critical national infrastructure.
- Taco Engelaar of Neara confirms that data center projects across Europe are being canceled due to lack of grid access, undermining regional ambitions to capture AI investment.
- National Grid is deploying dynamic line rating (DLR) on select circuits to increase capacity by adjusting energy flow based on weather, though only 275 kilometers of lines currently use the technology.
- David Adkins of National Grid emphasizes that doubling energy flow over the next five years will require building new overhead transmission lines, as grid-enhancing technologies alone are insufficient.
- Ofgem is preparing reforms to filter speculative data center proposals from viable ones and has threatened financial penalties for grid operators that fail to meet connection deadlines.
Why it matters: AI data center developers face mounting delays and cancellations across Europe due to grid constraints, while National Grid must balance rapid technological fixes with costly, long-term infrastructure builds—delaying access to a market worth hundreds of billions in compute spending.
