Data center moratoriums US haven’t stopped 2027 capacity boom

The headline number sounds dramatic: more than 300 local bans on new data centers. But the real story is more nuanced. A sweeping audit of moratoriums across 17 states shows that, while the pauses exist, they have only nudged a small slice of projects off schedule. In practical terms, about three projects in moratorium areas are likely delayed, amounting to a tiny share of what’s planned for next year.

Analysts tracked thousands of projects against local rules, and the takeaway is this: a moratorium is rarely a fatal blow to a data-center plan. Most projects already hold permits, or sit on land where approvals are effectively moot due to zoning, existing infrastructure, or pre-approved plans. Even in places with high-profile pauses, like New York or Texas, the impact isn’t as broad as it might seem at first glance.

So what does this mean for the next wave of data centers in the U.S.? The forecast still calls for a big jump in capacity. About 38 gigawatts of IT capacity are expected to come online in 2027, more than twice the 2026 figure. Of that 38 GW, roughly 22 GW are under vertical construction while the remaining 16 GW are mostly financed and in early site work. In other words, demand and construction momentum remain strong even as local rules complicate some schedules.

Two complicating factors complicate the picture. First, some bans don’t revoke existing approvals, and a lot of delays hinge on the exact timing of permits, site readiness, and overlapping timelines. Second, some pauses are temporary by design and could be lifted or altered as state agencies reassess capacity, reliability, and energy needs. In practice, that means the bans can push delivery dates, but they don’t automatically erase plans.

The data center industry and local communities aren’t off the hook yet. A handful of pauses have bite when governments set strict limits or when a moratorium slows new applications to a crawl. Still, the consensus in the audit is clear: moratoriums are more bark than bite today, unless they become broader, stricter, or longer-running.

Moratoriums aren't killing the US datacenter buildout.

Our analyst @mayabarkin finds only ~2.3 GW of ~21 GW in moratorium areas (excluding the TCEQ pause in Texas) is likely to be delayed, as cited in The Economist.
