Siemens Hands Over Thailand Plant
Addition of two CCPP units will bring total output to 1500 MW
Siemens and its Japanese partner Marubeni have completed the turnkey construction of combined-cycle power plant (CCPP) Chana 2 in Thailand and handed it over into commercial operation to the national power provider Electric Generating Authority of Thailand (EGAT).
The natural gas-fired Chana 2 plant consists of two units in a single-shaft configuration. With a total electrical capacity of around 800 MW and an efficiency of 57.3%, Chana 2 is one of the most efficient and environmentally friendly power plants in Southeast Asia, the company said.
Siemens’ scope of supply included an SGT5-4000F gas turbine, an SST5-3000 series steam turbine and an SGen5-2000H generator for each of the two units at Chana 2, as well as the overall electrical system, the SPPA-T3000 I&C system, and ancillary and auxiliary systems. The Japanese partner Marubeni was responsible for supply of the heat recovery steam generator (HRSG), the main transformers, the outdoor switchgear system, the cooling tower, and for erection and installation of the overall plant.
Chana is located in the Songkhla province in the south of Thailand. In 2008, Siemens and Marubeni erected the Chana 1 multi-shaft combined-cycle plant. With the addition of the two units, Chana 1 and 2 will supply a combined 1500 MW to the power grid in southern Thailand.
