Overview
- Microsoft confirmed Monday that it has terminated its agreement to be the anchor tenant at Nscale’s planned Loughton, Essex site after grid studies showed sufficient transmission power may not be available until the early‑to‑mid‑2030s.
- Nscale says it remains committed to Loughton, is exploring alternative power sources for the site and calls its wider relationship with Microsoft strong, but the loss leaves the Loughton project without a publicly announced customer.
- The company’s September S‑1 shows a $103.4 billion contracted pipeline that is highly concentrated with Microsoft and Anthropic accounting for roughly 85 percent of that figure, while only about 55 MW of capacity is currently energised in Europe.
- The setback raises fresh risks for Nscale’s planned NYSE listing and recent $3.36 billion pre‑IPO financing because contracted value converts to revenue only after facilities are powered and operating.
- The episode underlines a wider industry constraint: many data centres can attach to distribution networks but must wait for upgrades to the national transmission network, a process that can take years and reshape investor appetite for debt‑funded AI buildouts.
