Data center moratoriums US haven’t stopped 2027 capacity boom
More than 300 local pauses delayed just three projects, an October count found. Then the November 3 midterms put data center limits on a much bigger stage.
SemiAnalysis found more than 300 local data center moratoriums delayed only three projects, about 2.3 gigawatts of capacity.
Its forecast still has 38 GW of US data center IT capacity coming online in 2027, more than double 2026.
Most pauses miss because they don’t revoke approvals, don’t reach the site or expire before projects need permits.
On November 3, voters passed all but one of 40-plus restrictive ballot measures and elected Texas governor Gina Hinojosa, who promised a moratorium.

Local bans on new data centers have been mostly symbolic so far. Research firm SemiAnalysis checked more than 300 US moratoriums against thousands of projects and found only three likely to be delayed, about 2.3 GW of capacity. It still expects 38 GW to come online in 2027, more than double 2026.
The reason: most pauses only freeze new applications, so permitted projects and those on unaffected land carry on.
Michigan has 45 pauses but almost no affected projects.
A Texas state permit pause wasn’t in the count.
The firm’s real worry is a strict statewide ban.
That worry got sharper on November 3. Voters passed all but one of more than 40 restrictive measures, and Texas elected Gina Hinojosa, who promised an immediate moratorium. Watch ERCOT’s mid-December review and the new governor’s first moves.
More than 300 towns and counties across the US have hit pause on new data centers, and almost none of those pauses have stopped anything. An October audit by research firm SemiAnalysis found that only three projects, about 2.3 gigawatts (GW) of capacity, look likely to be delayed by local data center moratoriums.
That matters if you live near one of these huge server farms, pay an electricity bill in a fast-growing data center state, or own tech stocks. Local bans are the main tool residents have used to push back on noise, water use and rising power costs. The audit suggests that tool has been weaker than it looks. But that was before the November 3 midterms, when voters across the country turned data centers into a ballot issue and elected officials who promise much tougher limits.
01
What the data center moratorium count actually found
SemiAnalysis tracks more than 400 local restrictions across 17 states, a few of them permanent zoning bans. It defines a moratorium as a temporary legal pause, usually a freeze on accepting new applications. Its analysts checked each active restriction against records for thousands of planned projects.
The enacted local moratoriums cover about 20 GW of planned capacity, but only about 1.5 GW of that looks delayed. New York’s statewide pause adds roughly 0.8 GW more, bringing the total to around 2.3 GW out of 21 GW sitting in moratorium areas.
Compare that with the national pipeline. The firm still expects 38 GW of US data center IT capacity (the power available to run the servers) to come online in 2027, more than double the 2026 figure. Buildings are already rising for about 22 GW of that. Most of the remaining 16 GW has its money lined up, and crews are preparing the sites. SemiAnalysis says its forecast has barely moved in a year.
The pace of new pauses is still striking. New York, Texas, Pennsylvania and Oregon all acted within less than two months this summer.

Why most local bans miss their target
A moratorium only delays a project when everything lines up. It has to reach that exact parcel of land, be in force at the right moment, overlap the project’s timeline and cover the planned use in a way the developer can’t get around. Miss any one of those and the project carries on.
Most miss. Pauses don’t cancel approvals already granted, so anything under construction or fully permitted is out of reach. Short pauses can run out before a later project even applies. And for big builds, lawsuits or waits for equipment often set the real schedule anyway.
The examples show how this plays out:
Michigan has 45 enacted moratoriums but almost no exposure in its project pipeline. One reason: a Google campus in the state was built on land whose industrial zoning already allows data processing.
In Brownsville, Texas, the city removed the land picked for a SpaceX data center from within its limits, which puts the project beyond the reach of the local pause.
In Pennsylvania, one pause did bite: a township adopted it before NorthPoint applied for a special exception, pushing local approval to next year. NorthPoint is still pursuing the project.
SemiAnalysis concluded that moratoriums would need to be far more widespread and restrictive to slow the national build. One of its authors, Jeremie Eliahou Ontiveros, said the scenario that would worry the firm is a strict state-level pause that blocks even projects with their own off-grid power, naming Texas as an example.
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.

The 2.3 GW figure doesn’t include Texas’s biggest move. Gov. Greg Abbott told the Texas Commission on Environmental Quality (TCEQ), the state environmental regulator, to issue no permits for data center projects. Law firm Bracewell said that applies whether or not a project is in the queue of ERCOT, the operator of most of the Texas grid, and expects the freeze to hold until the grid operator wraps up its review in mid-December.
That pause has its own catch. An investigation later found Texas regulators kept processing permit applications, and Abbott’s office said the order blocked approvals, not processing.

How the midterm vote changed the outlook
The audit’s “more bark than bite” verdict, a phrase it borrowed from an Economist reporter, now faces a very different political map. Voters approved moratoriums, bans or other restrictions in at least 29 jurisdictions on November 3. Of more than 40 restrictive ballot measures tracked by Ballotpedia, all but one passed. Ohio, a key hub with gigawatts planned around Columbus, saw the biggest cluster.
The largest change is in Texas. Democrat Gina Hinojosa defeated Abbott after promising an immediate moratorium on new data center agreements. Wells Fargo estimates Texas holds 27% of planned US data center gigawatts. In Georgia, Keisha Lance Bottoms, who backed a statewide pause, won the governor’s race, and Democrats flipped the state utility commission that sets power rules.
Markets noticed. The day after the vote, shares of IREN, which runs two Texas campuses, fell 5% and CoreWeave dropped 4% while the wider tech market rose. MOCA Systems chief economist Brandon Michalski said the results will make him adjust his 2027 outlook and possibly soften construction expectations. Elon Musk joked on X that building data centers in orbit is starting to look attractive.
For residents, the lesson from the audit is about timing. A local pause works best before a developer files its applications, as the Pennsylvania township showed. Once a project is permitted or digging has started, a moratorium rarely changes much.
State-level action is different, and that is what the new governors in Texas and Georgia have talked about. Utility commission races in 10 states also shaped who decides how data centers connect to the grid, and Democrats who won control of Georgia’s commission promised to hold data centers accountable for power bills.
The next dates to watch are ERCOT’s review in mid-December and Hinojosa’s first moves after she takes office.

Are data center moratoriums in the US working?
Not much so far. An October audit found more than 300 local pauses delayed only three projects, about 2.3 GW, against 38 GW expected in 2027.
