New Jersey fines DataOne $1 million over unapproved generators

The violation and the response

New Jersey’s Department of Environmental Protection said the generators had not received state approval. Commissioner Ed Potosnak called the case the largest inspection of its kind against a data center in New Jersey, and possibly one of the largest in the country. He said the state was making clear that companies could not build and operate such facilities without consequences.

Residents had spent months pressing state and city officials for more transparency and accountability from developers. Vineland resident Matt Williams told Gothamist that locals had been pointing to violations for a long time and that the state’s action did not surprise him.

A project still taking shape

Construction began in early 2025, with Microsoft financing the project. Once fully operational, the center is expected to cost $17 billion and use 350 MW of power. Sierra Club New Jersey has described it as one of the largest data centers in the Northeast.

Vineland also granted the facility a five-year tax exemption. The case suggests that local pressure can still shape enforcement after a data center lease has been signed—but it does not answer what residents can do about the project’s longer-term footprint.

I think the more consequential question is what happens when the facility reaches full capacity. The fine addresses generators that operated without approval; the announcement says little about how the site’s projected power demand will be met, or how residents will be kept informed as construction continues. That leaves a tension between enforcing the rules around a live project and managing the infrastructure burden it is still expected to create.
