Everyone Says Datacenter Moratoriums Are Killing the US Buildout. We disagree

Original reporting by SemiAnalysis (Dylan Patel) — Maya Barkin · published Sep 15, 2026, 4:54 PM EDT

SemiAnalysis's satellite-tracked model says US datacenter capacity will more than double in 2027 despite four states and 300-plus localities moving to block new builds.

Key points

• SemiAnalysis forecasts 38GW of US datacenter IT capacity delivered in 2027, more than double 2026's total. source ↗
• SemiAnalysis says 22GW of that total is under vertical construction and most of the remaining 16GW is already financed. source ↗
• New York stopped datacenter environmental permits, Texas paused its ERCOT interconnection queue, and Pennsylvania and Oregon added restrictions. source ↗
• More than 300 towns, cities, and counties voted to halt datacenters over the past 18 months. source ↗
• SemiAnalysis's model tracks real-time and historical satellite imagery of over 6,000 datacenters. source ↗

Practical applications

• Before treating a state's moratorium headlines as a supply-cut signal, check project-level trackers such as SemiAnalysis's Datacenter Industry Model for what is actually under construction.
• When planning 2027 capacity commitments, weight the 22GW already in vertical construction as firm supply and discount the 16GW still in planning.
• If you develop or site datacenters, prepare community-facing answers on electricity cost, water, and land use, since those stated concerns are driving the 300-plus local votes.

Context

AI demand has triggered an unprecedented wave of US datacenter construction, and communities have pushed back over electricity costs, water use, land use, and other local impacts. Industry capacity is measured in gigawatts of IT load, and projects typically pass from financing through siteworks to vertical construction before delivery. SemiAnalysis, the research firm behind the forecast, tracks more than 6,000 datacenters using satellite imagery.

What to watch

• Whether the 16GW of planned capacity moves into vertical construction in coming quarters will confirm or undercut the 38GW forecast.
• Watch whether Texas reopens its ERCOT interconnection queue and whether more states join the four that have already acted.
