New Jersey Fines DataOne $1.07 Million for Unpermitted Generators at Data Center

The Vineland facility is being developed by DataOne for Nebius Group to support artificial-intelligence infrastructure under a $17 billion deal with Microsoft.
New Jersey regulations require a preconstruction permit and operating certificate for generators with a capacity of 37 kilowatts or more; each of DataOne’s generators was rated at 1,982 kilowatts.
DataOne said it already has the necessary approvals for the fuel-cell system intended to provide the site’s permanent power supply, while describing the natural-gas generators as temporary equipment.
More than 100 people protested the project in Vineland in March, citing concerns about noise, air emissions, water use and electricity costs; the rally was organized by local activists and Democratic congressional candidate Bayly Winder.
The Sherrill administration has recently established a separate electric-rate structure for large data centers and required operators to submit semiannual reports on their energy and water use.
New Jersey fined DataOne $1.07 million for installing and operating 62 natural-gas generators without required air permits at its planned 300-megawatt Vineland data center. The Mondonews reported that regulators discovered the unpermitted equipment during a July 29 inspection, though the generators had not been observed during a prior December 2025 visit. The Ars Technica investigation revealed satellite images showing the generators in operation, marking the state's largest enforcement action against a data center.
DataOne disputes the violation, claiming the generators are temporary backup equipment while it transitions to a permitted fuel-cell system. Yahoo News reported the company said it will apply for the necessary air permits and operating certificates. State regulators gave DataOne 45 days to obtain approval or stop operating the 1,982-kilowatt generators, which can emit carbon dioxide, nitrogen oxides, and other pollutants.
In December 2025, state environmental inspectors checked DataOne's Vineland site and found no unpermitted generators. New equipment appeared sometime between that visit and July 29, 2026, when regulators returned and discovered all 62 Caterpillar engines operating. Gadgetreview noted that maintenance logs later revealed the units had been running as early as October 2025.
The breakthrough came in mid-August when investigative journalists used thermal drone photography to capture the generators running. Ars Technica reported that imagery showed at least 45 units actively operating, providing visual proof of the violation. This evidence prompted the New Jersey Department of Environmental Protection to take enforcement action.
DataOne says the natural-gas generators are only temporary. The company filed an air-permit application in December 2025 for Bergen natural-gas engines but withdrew it in May 2026 after receiving deficiency notices. It then switched focus to a Bloom Energy fuel-cell system, which DataOne claims already has the necessary state approvals. Fuel cells produce electricity without combustion, avoiding some of the emissions problems.
DataOne operates the Vineland site for Nebius Group, an Amsterdam-based artificial-intelligence infrastructure company, under a $17 billion deal with Microsoft. The firm says grid interconnection delays force developers to install temporary backup power to meet project timelines. However, New Jersey regulations require preconstruction permits for any generator rated above 37 kilowatts—each of DataOne's units is rated at 1,982 kilowatts, over 50 times the threshold.
More than 100 residents protested the project in March, organized by local activists and Democratic congressional candidate Bayly Winder. Protesters raised concerns about noise pollution, air emissions, water use, and rising utility rates. The natural-gas generators now at the center of the fine intensified those worries, as they emit nitrogen oxides and carbon monoxide linked to respiratory problems.
The Sierra Club director Anjuli Ramos-Busot applauded the enforcement but criticized the penalty as too small. A $1.07 million fine, she argued, represents a negligible cost for a tech corporation pursuing a $17 billion deal. Environmental advocates are demanding a complete halt to generator operations until DataOne obtains full compliance with air quality laws.
Governor Mikie Sherrill's administration has recently imposed stricter rules on large data centers. The state created a separate electric-rate structure for these facilities and now requires them to submit semiannual reports on energy and water consumption. DEP Commissioner Ed Potosnak called the $1.072 million fine the largest ever issued against a data center in New Jersey, signaling zero tolerance for unpermitted power generation.
Analysts say the enforcement action sets a precedent for the entire East Coast. Hyperscale AI operators face pressure to comply with environmental regulations or face costly shutdowns. The fine could push companies to accelerate investments in cleaner power sources like fuel cells or grid-connected renewable energy, rather than relying on temporary fossil-fuel generators as workarounds.
