The project consists of expanding the existing power plant with a fifth unit. The Alstom-Marubeni consortium previously built the combined-cycle plant’s Unit-1 and the Unit-2 gas turbine peaking plant in 1995.
The new Unit-5 will increase the total output of the plant by 235MW from the current 1,800MW, thus helping the country to meet the current high electricity demand on the Java-Bali grid. The plant will be operated with natural gas, to help the country reduce its dependence on liquid fuel.
Under the terms of the contract, Alstom will engineer, procure and commission a fully integrated power island, consisting of one GT13E2 gas turbine with one heat recovery steam generator, one Comax steam turbine, two turbogenerators and the Alspa control system.
Alstom will engineer and manufacture the heat recovery steam generators at its local boiler facility in Surabaya, Indonesia. Marubeni will supply the balance of plant, high voltage switchyard, civil works and will also provide erection services.
