Siemens delivers Chana 2 combined cycle power plant in Thailand

Siemens and Marubeni have delivered the Chana 2 combined cycle power plant to Electric Generating Authority of Thailand (EGAT).

Located in the Songkhla province in the south of Thailand, the 800MW natural-gas-fired plant features two units in a single-shaft configuration.

A consortium of Siemens and Marubeni built the Chana 1 multi-shaft combined cycle plant in 2008, and two further combined cycle units have been added to the site currently.

Siemens supplied a model SGT5-4000F gas turbine, an SST5-3000 series steam turbine and a model SGen5-2000H generator for each of the two units at Chana 2.

The company also supplied the entire electrical system, the SPPA-T3000 I&C system as well as the ancillary and auxiliary systems.

Marubeni supplied the heat recovery steam generator, main transformers, outdoor switchgear system and cooling tower.

Siemens Energy Power Generation Division project management head Lothar Balling said: “We are pleased to hand over the two units of Chana 2, the first single-shaft power units for EGAT, in commercial operation after only a few weeks following the very successful and on-schedule completion of our multi-shaft combined cycle project Wang Noi 4, thanks to the excellent cooperation with Marubeni and EGAT.”

EGAT power plant development deputy Governor Khun Ratanachai Namwong said: “Chana 2 marks the second plant erected by Siemens and Marubeni that has gone online this year, enabling us to respond in good time to the high electricity demand in the south of our country.”
