Planned UK Data Center Delayed Until 2030s Over Power Grid Delays. Microsoft Pulls Out

Nvidia-backed Nscale is constructing a £2bn data centre in Loughton, Essex, with Microsoft as its primary tenant. However, the project faces a significant setback due to delays in obtaining power grid connections. According to reports, the issue is not solely Nscale's responsibility but rather a broader problem with Britain's grid-connection times, which have become a major obstacle for new data centre developments. Some projects in the UK are facing waiting periods of nearly a decade for adequate power supply.

Initially, Nscale anticipated receiving power at the end of the year, but this has now been pushed back to the 2030s. Microsoft, as the anchor tenant, has decided to withdraw from the Essex deal, leaving the site in a state of uncertainty. The company's decision could potentially derail Nscale's plans for a potential Wall Street flotation valued at up to $35bn (£26bn), despite a recent downturn in AI computing stocks.

Rising interest rates and inflation have also contributed to a decline in share prices for rival data centre developers. Tech analyst firm Gartner has warned that up to $4 trillion in asset value could be at risk of write-downs by 2032 if the AI boom does not meet expectations. Gartner estimates that AI providers are set to invest nearly $7 trillion between 2027 and 2030, but they project that only a 12% return on invested capital (ROIC) will be achieved by the end of 2032.

This analysis suggests that a significant portion of AI-optimized infrastructure providers may cease operations by 2030 due to cost pressures and a lack of a unique business model.
