Wang Noi Power Plant n brief

The power plant is equipped with 3 combined cycle blocks, incorporating 6 gas turbines and 3 steam turbines. The official synchronization was completed in April, 1996 and the Commercial Operation date (COD) in May, 1996. The main fuel for plant generation is natural gas from two sources – the Gulf of Thailand and Myanmar. Diesel oil of 60 million liters has been reserved as supplementary fuel in case of gas supply interruption. The total capacity of Wang Noi Power Plant is 2,027 MW and the gross production from 1996 to 2011 was 147,428,708,433 million kWh.

An Inlet air cooling system of 20,000 ton is installed at Block 3 of the combined cycle power plant. The installation was completed in June 2012 and can further enhance the capacity by 70 MW to the gross generation. Wang Noi Block 4 combined cycle power plant is currently under construction. The project will be completed in June 2014 and will add the capacity of 785 MW to the present generating system.

Wang Noi Power Plant developed an emergency response plan by building a flood barrier during Thailand’s worst flood in 2011, that protect and saved the power plant from severe impact. This barrier was enhanced to cover 5 kilometers in length to protect the total area of 1.28 million sq meters.
