For companies seeking to build a giant data centre in Great Britain right now, the biggest bottleneck isn’t a shortage of cutting-edge chips, a lack of capital eager to fund the next wave of large language models (LLMs) or inference workloads, or the availability of software engineers who understand neural networks. The bottleneck is the electricity grid and associated infrastructure, which currently features a waiting list that can stretch comfortably into the next decade.
For technology companies trying to build at scale, waiting seven or eight years to plug your servers into the grid creates a competitive and commercial problem. Software architectures evolve rapidly, investor timelines are finite, and competitors in other countries may advance more quickly.
Ofgem – the UK energy regulator – has released an update to its Demand Connections Reform strategy. It is a detailed look at what happens when trillion-dollar Silicon Valley ambitions run into the physical, regulated reality of a legacy electricity system.
