Wilton International

What Wilton International does

Wilton International is a 2,000-acre multi-occupancy industrial site in Teesside, UK, operated by Sembcorp Utilities (UK) Limited, a wholly-owned subsidiary of Singapore-listed Sembcorp Industries Ltd. Originally developed by ICI from 1949 and acquired by Sembcorp in 2003, the site provides large-scale development land, integrated energy and utilities, and shared infrastructure to energy-intensive industrial businesses. Core assets include the UK's largest private wire electricity grid with four on-site generation units (gas, biomass, energy-from-waste), the 30MW Wilton 10 biomass power station, the 42MW Wilton 11 waste-to-energy facility, 120km of owned pipelines and service corridors, and 120MWh of operational battery storage expanding toward 1GW/8GWh.

The site operates as a plug-and-play industrial platform: development plots of 2.5 to 66 acres are available with pre-consented planning, flexible tenancies (including virtual freehold), and Freeport tax incentives within Teesside Freeport. Beyond power, Wilton supplies steam, demineralised/raw/potable water, natural gas, compressed air, and access to industrial gases (via BOC). Multimodal logistics include private rail sidings, direct pipeline connection to the UK ethylene pipeline, and 2.5-mile proximity to Teesport, a top-5 UK liquid bulk port. The site hosts anchor tenants in petrochemicals (SABIC, second-largest ethylene cracker in Europe), polyurethanes (Huntsman), polyesters (Alpek), bioethanol (Ensus), plastics recycling (Biffa Polymers), fertilizers (Anglo American polyhalite processing), and emerging decarbonisation tenants (Tees Valley Lithium, LanzaJet, Willis Sustainable Fuels, NatPower, Digital Reef).

Revenue mechanics combine recurring land leases and multi-year utilities supply contracts (steam, water, power, gases) with usage-based power generation sold to National Grid and ancillary grid services from battery storage and flexible generation. Pricing is not publicly disclosed; agreements are customised B2B contracts. Go-to-market is direct enterprise sales by Sembcorp's commercial team targeting energy-intensive manufacturers, clean-energy operators, and high-technology industrial users. The site participates in cluster networks (NEPIC) and benefits from co-marketing with Teesside Freeport, Tees Valley Combined Authority, and Redcar & Cleveland Borough Council.
