Tees Valley 1 (TV1) is located on an eight hectare site to the south of the North Tees Access Road (Huntsman Drive) at Seal Sands. TV1 is the the largest advanced plasma gasification renewable energy facility and the first of its kind in the UK. TV1 is located on an industrial site adjacent to the North Tees Chemical Complex.
Situated in an area with access to the local and national electrical distribution infrastructure and in close proximity to existing landfill disposal facilities, it diverts up to 350,000 tonnes of non-recyclable waste from landfill per year; helping to meet the UK's landfill diversion targets.
Tolent’s scope was the construction of piled foundations (with the largest pour 1100m³), large reinforced concrete structures for the gasifier and waste transfer bunkers (which were up to 15m high), GRE pipework up to 1.2m diameter for the cooling water systems, a large cooling tower basin, fire mains, earthing, electrical cabling, specialist coatings, drainage, security fencing and turnstiles, weigh bridges, road works and car parking.
At the peak of the civils works, Tolent had over 200 directly employed local personnel working on this site. On completion of the project, over 20,000m³ of concrete and over 2,500 tonnes of reinforcement had been installed.
The existing ground conditions of the site consisted of 5m of crushed blast furnace slag overlying the silts and sands of the old Tees estuary. The blast furnace slag was excavated, crushed and screened to provide quality stone and aggregates for use on the project.
Nearing completion of the main civils project the client placed a separate contract with Tolent for the design and construction of the plant control building along with 9 associated plant and warehouse/storage buildings on the site, as-well-as the surface finishes work of the concrete slabs and graveled areas.
