Details have emerged about AI cloud Nebius’ plans to develop a large data center in Pennsylvania.

Announced this month, the Nasdaq-listed company is developing a campus in Butler Township, Pennsylvania, within Schuylkill County’s Highridge Business Park, some 55 miles (89 kms) west of Allentown.

Located at the intersection of Interstate 81 and Gordon Mountain Road in Highridge Business Park, the purpose-built campus will be fully owned and operated by Nebius.

The site will span ~600 acres and deliver 1.2GW of capacity upon full buildout, with an initial phase of 260MW expected to be operational by October 2027. The site could reach 660MW by 2029 and more than 1GW after that. Site plans suggest six single-story buildings are planned.

“The area offers a compelling combination of infrastructure, workforce, and local leadership — including proactive zoning that permits data center development –– and we believe there is strong potential to create a long-term, mutually beneficial partnership with the community,” the company said.

Nebius announced plans for a 1.2GW data center campus in Pennsylvania in May 2026. Few details were shared at the time, but the company’s CEO, Arkady Volozh, said 250-350MW would be live by the end of 2027.

The AI cloud firm said it has secured a dedicated energy service agreement with PPL Electric Utilities for the project. Nebius said the campus is designed to include a Battery Energy Storage System (BESS) capable of providing backup and redundant power for approximately 30 minutes in the event of an outage.

The site will use both air- and liquid-cooling, and use closed-loop cooling to reduce water use.

Nebius has a data center presence across the US, the Middle East, and Europe. In the US, the firm is set to lease data centers in New Jersey (Vineland, DataOne) and Missouri (Kansas City, Patmos). The firm is also developing its own data centers in Independence, Missouri, and Birmingham, Alabama.

Nebius counts Meta, Microsoft, and AI model firm Reflection as customers.
