DataOne's temporary generator fleet had 122.9 MW of nameplate capacity: 62 machines rated at 1,982 kW each. That is about 41% of the 300 MW ceiling for the AI data-center campus in Vineland, New Jersey. On September 22, the state assessed a $1.07 million civil penalty because the generators had been installed and operated without the required air permits. The arithmetic turns a local enforcement case into a warning for the AI compute business. Power approvals can sit directly on the delivery schedule.
That schedule carries real commercial weight. Nebius agreed to supply Microsoft with dedicated GPU infrastructure from Vineland in several tranches, and its regulatory filing puts the base contract at about $17.4 billion through 2031. The same filing says Microsoft can terminate a GPU service after a grace period if Nebius misses an agreed delivery date and cannot offer alternative capacity. A permit for the equipment feeding the racks is therefore more than a facilities detail. It can affect whether contracted compute becomes available on time.
The contract also lets Microsoft buy more services or capacity, which could lift its value to about $19.4 billion. Nebius said cash from the agreement would finance some of the related capital spending. Those terms explain the scale and timing pressure around Vineland, but they do not explain the permit lapse or assign responsibility for it. They do show why a delay at the power layer can travel upward into financing, installation and customer delivery dates.
A 37 kW rule met 1,982 kW machines
New Jersey requires a preconstruction permit and a valid operating certificate for a generator rated at 37 kW or more. Each DataOne unit was rated at more than 53 times that threshold. The Department of Environmental Protection's notice says its July 29 inspection found 62 stationary, reciprocating natural-gas engines at the site. The agency's previous inspection, in December 2025, had not found them.
The DEP notice says DataOne installed and operated the generators without first obtaining either approval. Natural-gas engines release carbon dioxide, nitrogen oxides, carbon monoxide and other combustion pollutants, which is why the equipment enters the air-permit system before construction. The order requires DataOne to apply for and obtain the permits or stop operating the units. The $1.07 million figure is an assessed penalty, and the public record cited here does not establish that it has been paid.
DataOne has disputed the state's classification of the temporary equipment. In a statement reported by Floodlight and the Guardian, the company said it would apply for permits and was discussing the transition schedule with the DEP. The Guardian reported that the agency gave DataOne 45 days to comply and allowed the generators to keep running during that period. The company can continue operating while that compliance clock runs.
The power bridge was nearly half the planned campus
Nebius announced the Vineland project in March 2025 as its first major US data center. It said the site could expand to 300 MW and described a plan to bring the first phase online in 20 weeks. Its launch announcement also set a target of 100 MW of installed capacity by the end of 2025, with room to move faster if demand required it. Speed was part of the offer from the start.
New Jersey's equipment figures put the fleet at 122.9 MW of nameplate capacity. That figure does not show how much power the site drew. Generator ratings give the maximum stated output, while the available record does not reveal the load on each engine, its operating hours or the electricity consumed by servers. Even with that caveat, the combined rating exceeded Nebius's original 100 MW year-end target and equaled a substantial slice of the full campus plan.
The parties also have distinct roles. Nebius says the facility is a build-to-suit project for its use, while DataOne owns and operates the site and Nebius installs and manages the server and GPU infrastructure. The project's current information page says DataOne plans to power it off-grid with Bloom Energy fuel cells and now expects the AI factory to be operational by 2027. The page does not mention the generator penalty.
That separation matters when customers assess a cloud region. The GPU provider, building owner, power contractor and end customer may be different companies, yet a missed permit can still reach the same delivery chain. Nebius's Microsoft filing makes availability a condition of the deal. The New Jersey order shows that availability depends on paperwork and equipment outside the server hall as well as GPUs, networking and cooling.
A thermal image became compliance evidence
The regulator had already seen the generator fleet during its July inspection. Public scrutiny sharpened in August, when Floodlight flew a thermal drone beside the partly completed site. The visual investigation found heat signatures from at least 45 of the 62 generators, indicating that those units were operating during the flight. The DEP then confirmed to the reporters that it had issued no permits for power generators at the facility and had no applications under review at that time.
A thermal image cannot measure a site's annual emissions, and one flight cannot establish its full operating history. The August investigation answered a narrower question: which large machines appeared to be running during the flight? Its visual count lined up with the equipment the state later named in its enforcement action. The reporting made the gap between installed hardware and the permit record visible, while the state inspection and legal order established the violation.
The sequence also exposes a monitoring lag. The generators were absent from the DEP's December 2025 inspection, present when officials visited on July 29, and visibly active during Floodlight's August flight. The agency announced its penalty on September 22. Those dates come from the state release and the reporting that prompted wider attention. They do not show exactly when every engine started or how often each one ran.
Temporary power still needs a permit trail
DataOne says the gas generators are temporary and that approved, lower-emission fuel cells will become the permanent power source. The state order still applies to the engines operating in the meantime. It addresses the generator fleet, while Nebius's project page describes the future fuel-cell setup. An approved permanent plan can coexist with an unresolved compliance problem in the temporary bridge.
The fuel-cell plan changes the type of impact while leaving the project's energy demand in place. Floodlight's earlier investigation reported that the proposed Bloom system would use a combustion-free electrochemical process, producing less local air pollution than the Bergen gas engines DataOne had previously proposed. A Bloom official also testified that a completed 300 MW system could emit more than 2 billion pounds of carbon dioxide each year. DataOne withdrew its earlier engine-permit application in May, according to records reviewed by Floodlight.
For infrastructure buyers, the useful due-diligence question is concrete: what powers the advertised capacity today, and which permit number covers it? The answer may differ from the permanent energy diagram in a launch presentation. Delivery commitments also deserve a second check against the dates when temporary and permanent power sources are legally allowed to operate. Vineland's five-year GPU contract makes that dependency unusually easy to see.
The next evidence to watch is the permit docket after DataOne's 45-day window and the site's actual power mix as the fuel cells arrive. A penalty records the state's finding, but it does not tell a customer how many megawatts can run lawfully on the next delivery date. That answer will come from issued permits, operating records and whether the temporary fleet remains in service.
