US data‑center pipeline 50% stalled
- Sightline Climate says 30% to 50% of U.S. data-center capacity slated for 2026 will miss deadline, as power access and equipment shortages choke builds. (sightlineclimate.com) - The bottleneck is physical, not financial — only about 5 GW is under construction, cancellations hit 25 in 2025, and transformer waits stretch years. (sightlineclimate.com) - That matters because AI power demand is still climbing fast, while developers are already tapping junk-bond markets to finance projects that may open late. (goldmansachs.com)
The U.S. data-center story has changed. For the last two years, the assumption was simple — if Big Tech wanted more AI capacity, it could just spend its way into ex(sightlineclimate.com)ansformers, interconnection queues, and local governments that do not want a giant power-hungry box dropped into town. That is why Sightline Climate now (sightlineclimate.com)e by year-end. (sightlineclimate.com) ### What exactly is being delayed? This is mostly about(goldmansachs.com)tline’s February 24, 2026 outlook says announced 2026 capacity still looks huge, but a big chunk of it is unlikely to materialize on schedule. The issue is not that projects were never announced. The issue is that many of them have not moved far enough through construction and power hookup to plausibly open when promised. (sightlineclimate.com) ### Why is power the real chokepoint? A modern AI data center is basically a power project wearing a com(sightlineclimate.com)s, switchgear, backup systems, and utility approval for enormous new loads. Interconnection queues have stretched into multi-year waits, and developers are running into a grid that was not built for clusters demanding hundreds of megawatts at once. (datacenterfrontier.com) ### Why are transformers suddenly a big deal? Because they are the unglamorous part that makes the (sightlineclimate.com)upply, and lead times have blown out from something manageable into something that can break a project schedule. Industry coverage this spring described waits of years for critical electrical equipment, which means a developer can have land, capital, and customers lined up and still be stuck waiting for hardware that nobody notices until it is missing. (datacenterfrontier.com)uction Dive says cancellations jumped to 25 projects in 2025 from six in 2024, citing Baird analyst Justin Hauke. The complaints are not abstract. Residents object to noise, water use, tax deals, land consumption, and the idea that utilities will prioritize server farms over homes or factories. Once that opposition hardens, state and local officials get slower, and slower is often enough to wreck a data-center timeline. (constructiondive.com)center power demand could rise 165% by 2030 versus 2023, and the IEA said in April that data-center electricity use is set to more than double by 2030. So the pipeline is not collapsing because AI demand vanished. It is colliding with the physical speed of the grid and industrial supply chain. (goldmansachs.com) ### Are developers still raising money anyway? Yes, and that is what makes this phase(constructiondive.com)nds this week, showing investors still want exposure to AI infrastructure. But borrowing does not manufacture transformers faster or clear a utility queue. It just keeps projects funded while they wait. (news.bloomberglaw.com) ### So what changed in the story? Basically, the market has moved from a chip shortage narrative to an in(goldmansachs.com)er problem to solve because you cannot brute-force a substation, a transmission upgrade, or community acceptance the way you can pre-order servers. (sightlineclimate.com) ### Bottom line AI data centers are still coming. But the U.S. buildout is starting to look less like software scaling and more like utility construction — capital-heavy, locally contested, and slow in exactly the places investors hoped would be fastest.
