A consortium comprising of Siemens AG, Siemens Ltd. Thailand and the Japanese partner Marubeni has completed the Wang Noi 4 combined cycle power plant in Thailand on schedule.
The owner, the state-owned utility Electricity Generating Authority of Thailand (EGAT), took the power plant into commercial operation on April 7, 2014. The natural gas fired power plant features an efficiency of over 57.3 percent with an generation capacity of 770 MW.
For Unit 4 of the Wang Noi power plant complex Siemens supplied the main components, comprising two model SGT5-4000F gas turbines, an SST5-5000 steam turbine, three SGen-1000A generators and the SPPA-T3000 instrumentation and control system.
The multi-shaft unit Wang Noi 4 is located in the vicinity of the Thai capital Bangkok, and is an extension of a power plant complex that is already home to three units. For unit 4, Siemens supplied the main components, comprising two model SGT5-4000F gas turbines, an SST5-5000 steam turbine, three SGen-1000A generators, and the SPPA-T3000 instrumentation & control system.
Siemens was also in charge of commissioning of Unit 4. Marubeni supplied the heat recovery steam generators, the main transformers and the cooling tower. Siemens' partner in the consortium was also responsible for the civil works and erection of the plant.
Following Wang Noi 4, the Siemens and Marubeni consortium will be completing Chana 2 CCPP, a further two single-shaft unit in the summer of 2014. Power plants with Siemens turbine generator sets, including Chon Buri IPT, Chana 1 (previously known as Songkhla), Bang Pakong 5, and Glow are making a major contribution to environmentally friendly power generation in Thailand.
