Data‑centre builds hit a wall
What happened
About half of planned U.S. data‑centre builds have reportedly been delayed or cancelled because of shortages in power infrastructure and parts sourced from China, constraining the cloud capacity that many robotics and AI projects depend on. That slowdown shifts some deployment pressure back onto local inference and edge compute strategies as cloud scale becomes less certain. (tomshardware.com)
Why it matters
Market trackers find roughly 12 gigawatts of new data‑center power capacity were announced for the U.S. in 2026, but only about one‑third of that capacity is actively under construction right now. (sightlineclimate.com) The immediate hold‑up is the electrical supply chain and utility connection queues rather than a shortage of servers: delivery waits for large grid equipment and approvals to hook a site to the power system now stretch into multiple years, prompting developers to slow or cancel projects. (bloomberg.com) A transformer is the piece of equipment that raises or lowers voltage so power can be moved long distances and then delivered safely to a site, and switchgear is the set of switches and breakers that control and protect electrical circuits; both are critical parts of the "power chain" for a data center, and lead times for large transformers and grid interconnection approvals have ballooned to multiple years. (cisa.gov, powermag.com) The supply crunch is partly global: U.S. builders have leaned on imports for some specialized electrical gear, which has tightened as demand surged for both data centers and electrification elsewhere, and hyperscalers are spending heavily on power strategies — buying generation pipelines or planning on‑site power — to avoid multi‑year grid waits. (bloomberg.com, sightlineclimate.com) Concrete signs of the downstream impact: a major hyperscale campus being built for advanced AI training is sized to use about 1.2 gigawatts of power when finished, and industry trackers show total U.S. construction pipeline capacity fell near the end of 2025 as projects paused for permitting, interconnection and equipment waits.
