- Generators running: 45 of 62
- Campus capacity: 300 MW
- Microsoft-Nebius deal: $17 billion
- DEP site inspection: July 29
DataOne ran at least 45 of the 62 generators at its Vineland, New Jersey construction site in mid-August. The state has issued no air permit for any of them. The nonprofit newsroom Floodlight recorded the running units with a thermal drone and published the footage on August 27, 2026. The New Jersey Department of Environmental Protection said it has issued no permits and has no application under review for power generators at the site. City inspectors twice ordered work stopped this month. DataOne is building the 300 MW campus for Nebius, the AI infrastructure company behind a $17 billion contract with Microsoft.
The permit history explains the gap. DataOne applied to run 32 gas engines and 6 diesel generators. The DEP found several deficiencies in that application. DataOne withdrew it in May and switched to a plan for 300 MW of Bloom Energy fuel cells. Floodlight put the projected output of those fuel cells at more than 2 billion pounds of carbon dioxide a year. The units running on site now are neither of those things. They are trailer-sized generators that maintenance logs show operating since October.
State and city regulators both visited the site this summer. DEP inspectors observed natural gas generating equipment during a July 29 inspection. Vineland issued a stop-construction order on August 6 over an LNG tank installed without approvals. The city issued a second order on August 10 over the Bloom Energy units. That order says the city held no prior approvals, plans or permits for them. The site sits about 40 miles from Philadelphia and about a mile from two schools.
Enforcement Reality
Nobody has fined DataOne. Bruce Buckheit, who ran air enforcement at the EPA, reviewed the evidence and said the units violate federal law. He said the company should stop operating them and pay a penalty for the illegal emissions. The DEP has taken a slower line. A spokesperson said the agency will make a full compliance determination after it receives and reviews the information it requested. DataOne says it remains committed to meeting all applicable environmental and permitting requirements. Construction continues.
Why It Matters
An air permit is the one point where a state prices a data center’s local pollution before the load arrives. Vineland shows what happens when the build schedule outruns that step. The generators ran for roughly ten months before drone footage forced the question, and the penalty for that head start is still zero. Developers reading this case will note that withdrawing a deficient application removed the paperwork but not the engines. States writing large-load rules should treat construction power as a permitting category, not a footnote.
Critical Perspective
The evidence here is thermal imagery read by one retired regulator, and thermal imagery shows heat rather than permit status. Floodlight’s own count moved from 25 running units in late June to at least 45 in mid-August. Part of that jump is more machines, and part of it is a better camera angle on the same yard. Nobody has published run-hours for any unit, and air liability turns on hours far more than on how many units a drone caught at one moment.
The DEP inspected the site on July 29 and has still issued no violation notice a month later. Read one way that is a slow agency. Read another way it is an agency that has not yet decided construction-phase generators need the same permit as permanent generation, which is a real distinction in air rules and one the reporting does not resolve. The stop-construction orders that Vineland did issue covered an LNG tank and the Bloom units, not the generators actually running.
