Siemens will supply two highly efficient H-class gas turbines as key components to the power plant South Bangkok, Thailand. Siemens will deliver the key components consisting of two SGT5-8000H gas turbines, two SGen5-3000W generators and two steam turbines of model SST5-5000. Also included in the scope of supply are two heat recovery steam generators engineered by NEM and the SPPA-T3000 control system. The consortium partner Marubeni is responsible for civil and erection works, cooling tower, high voltage gas insulated switchyard and some balance of plant equipment. The power plant is constructed on the basis of the Siemens single-shaft concept, in which the major components (gas turbine, generator and steam turbine) are arranged in one single train.
