Nhon Trach 2 Power Plant Completed

Posted on November 10, 2011

The Nhon Trach 2 combined cycle power plant has started commercial operation in Vietnam. Siemens supplied the power block comprising main components such as gas turbines, heat-recovery steam generators, steam turbine, generator, and instrumentation and controls. The general contractor Lilama erected the power plant for customer Petro Vietnam Nhon Trach 2 Joint Stock Co.

With an installed capacity of 760 MW and an efficiency of more than 57%, Nhon Trach 2 will make an ecofriendly contribution toward meeting the country’s power demands. Due to Siemens’ burner technology, the plant’s nitrogen oxide emissions are at less than 15 ppm, according to the company.

The Nhon Trach 2 combined cycle plant is located in south of Dong Nai Province, about 35 km from Ho Chi Minh City. For the multi shaft plant in which the gas turbines and the steam turbine are each coupled with a dedicated generator, Siemens supplied the power block on a turnkey basis. It comprises two SGT5-4000F gas turbines, two heat-recovery steam generators, an SST5-5000 steam turbine, three SGen-1000A air-cooled generators, the entire electrical equipment and instrumentation and controls (SPPA-T3000) as well as the ancillary and auxiliary systems. In the future, Siemens will assume responsibility for providing maintenance of the main components.

Vietnam is one of the fastest growing countries in Southeast Asia and its power demand is increasing 11 to 13% each year. Power plants with a combined capacity of a 21 GW are installed there, which is only sufficient to meet one-tenth of actual power demand.
