Combined-cycle power plant
Tees combined-cycle power plant (CCPP) is a 1.7GW gas-fired power station being developed by Sembcorp Utilities in Middlesbrough, UK.
It is the third major project to be approved in 2019 and will be built with an estimated investment of £700m ($914m). The project comes under the nationally significant infrastructure project (NSIP) under the Planning Act 2008.
Sembcorp Utilities submitted the application for the power plant to the planning inspectorate in November 2017, which was accepted in December 2017. The UK Government granted consent for the development of the power station in April 2019.
The project is expected to require more than three years for the completion of construction. It will have the capacity to generate power for up to 1.5 million households.
It will also create more than 1,000 jobs during the construction phase and from 60 to 80 permanent jobs upon commencing operations.
Tees combined-cycle power plant location
The Tees CCPP will be built on a 15ha brownfield site at the 2,000-acre Wilton International industrial complex located near Redcar, Teesside, UK.
The site was previously occupied by the former Teesside power station, which ceased operations in 2013. The site can be accessed through the A1053 Greystone Road dual carriageway, which is part of a strategic trunk road network.
Tees combined-cycle power plant details
The new combined-cycle power station will be equipped with two gas turbine units, two steam turbine units, ancillary plant, and other equipment, which will be part of the main power island.
Additional infrastructure facilities include a heat recovery steam generator (HRSG) building, stacks, cooling towers, control and office building, and a workshop. The hybrid cooling towers will be placed towards the northern side of the plant.
Electricity generated by the power plant will be transmitted through two substations, which are currently in operation supporting the broader Wilton complex. The power plant will also have provision for placing carbon capture equipment in the future.
Natural gas supply for Tees power plant
The plant will make use of the existing gas and national grid connections of the former Teesside power station. It will also have provision for connecting to gas transmission infrastructure and to the national grid.
Natural gas for the project will be supplied through the existing 60cm pipeline connecting to the national transmission system via an above-ground installation (AGI) at Billingham.
It will also receive gas from an onshore gas processing plant at Seal Sands, Teesside, through an optional 20cm-diameter pipeline, which can be used as a back-up connection.
Other infrastructure improvements
Road access for the project will be provided through an existing access point from the A1053 Greystones Road. Construction of internal roads as well as emergency access routes and site security will also be undertaken.
The project will require the construction of temporary buildings and structures for use during the construction period. A dedicated space for car parking and hardstanding will also be built.
Sembcorp Utilities contracted DWD for providing strategic planning advice through the Development Consent Order (DCO) process. It also provided a planning statement, design and access statement, and consultation report and is supporting in the examination process of the project.
