Electricity boost for Norfolk

Siemens has received an order for a new combined cycle gas turbine (CCGT) at King’s Lynn power station in Norfolk, United Kingdom, owned by British energy and services company Centrica. The gas-fired power plant will consist of one unit in a single-shaft configuration and deliver a total capacity of approximately 380 megawatts (MW) to the grid. This is sufficient to provide electricity for approximately 380,000 British households. The agreement includes the installation and longterm servicing of a gas turbine, the servicing of a generator and a steam turbine, as well as the modernisation of the existing instrumentation and control systems.
The scope of supply encompasses the replacement of the existing V94.3 gas turbine with a new SGT5-4000F gas turbine, delivered from the Siemens gas turbine factory in Berlin, Germany. In addition, the existing generator and steam turbine will be refurbished at the Siemens site in Newcastle, UK. Also included in Siemens’ scope of supply are services including the extension of the existing air-cooled condenser (ACC) and an update of the existing distributed control system (DCS) to the latest SPPA-T3000 control system. Centrica will refurbish the heat recovery steam generator (HRSG) and parts of the balance of plant. The long-term service agreement (LTSA) between Siemens and Centrica is for a period of 12 years and includes spare parts, the performance of scheduled turnkey outages, as well as Power Diagnostics, part of Siemens’ digital services for energy portfolio.
The power plant in King’s Lynn is constructed on the basis in which the major components (gas turbine, generator and steam turbine) are arranged in one single train.
