Two Orders From Thailand For Siemens

Posted on August 18, 2011

Siemens Energy has received two orders from Thailand for the engineering, procurement and construction of combined cycle power plants. Siemens will build Chana Block 2 in the province of Songkhla and Wang Noi Block 4 in the vicinity of Bangkok together with its Japanese partner Marubeni. Chana Block 2 will be the first single-shaft power plant built in Thailand based on a Siemens design whereas Wang-Noi will be of multi shaft configuration.

The purchaser is the state-owned utility Electricity Generating Authority of Thailand (EGAT). The two power plants, each with an installed capacity of 800 MW, are scheduled to come online in the summer of 2014. The total investment volume amounts toUS$1 billion (€698 million) with more than half for the Siemens scope of supply.

Siemens will build the natural-gas-fired power plant Chana Block 2 as an extension to the Chana Block 1 plant using the Siemens single-shaft concept in which the main components are arranged on one shaft. Siemens scope of supply includes the main components, namely an SGT5-4000F gas turbine, an SST5-3000-series steam turbine, an SGen5-2000H generator, the entire electrical equipment, an SPPA-T3000 I&C system, and the ancillary and auxiliary systems. Marubeni will be responsible for supply of the heat-recovery steam generator, the main transformers and switchgear, and for construction and installation of the overall plant.

The Wang Noi Block 4 combined cycle power plant will be constructed in the vicinity of Bangkok as an extension to the existing complex Wang Noi Blocks 1 to 3. The plant will be of multi-shaft design consisting of two SGT5-4000F gas turbines, an SST5-5000 steam turbine, three SGen-1000A generators, the entire electrical and I&C (SPPA-T3000) equipment, and the ancillary and auxiliary systems.
