Singaporean state-owned energy and urban development company Sembcorp is looking to build a 280MW data center at Wilton International, an industrial park in Teesside, North East England.

The company’s British subsidiary Sembcorp Energy UK hopes to develop the data center with Digital Reef, a property firm that is also behind a proposed 600MW data center in Havering, Essex.

The pair are looking to build three data center buildings on a 154,553 sqm (1,663,595 sq ft) land parcel acquired by Sembcorp for £3.5 million ($4.7m) in July 2025.

The site was formerly owned by Peak Rare Earths, an Australian mining company that was acquired by Chinese rare earths producer Shenghe Resources in September 2025

Sembcorp and Digital Reef intend for the campus to be air cooled, according to a document submitted as part of the application.

The company filed its application on May 8 and announced the development this week, as consultation opened on the plans.

Wilton International is owned by Sembcorp, and boasts the country’s largest private wire electricity grid. It includes four on-site power generation units that use gas, biomass, and non-recyclable domestic waste.

Other occupants in the park include mining company AngloAmerican, chemical company Huntsman, waste management company Biffa, and polyester producer Alpek Polyester.

Teesside refers to the area around the River Tees and includes the boroughs of Middlesbrough, Stockton-on-Tees, and Redcar and Cleveland.

Reports emerged last year that the area, formerly home to the 4,500 acre Teesside Steelworks, was being eyed as the UK’s second AI Growth Zone. But the coveted designation, which provides financial incentives and priority access to power for data centers, has yet to be granted.

A plan to build a data center on the former steelworks was approved by the Redcar and Cleveland Council last August, forcing oil and gas giant BP to give up on its plans to build a hydrogen project on the same site.
