Nhon Trach 2 Combined Cycle Power Plant

On 4th October 2012, Nhon Trach 2 Combined Cycle Power Plant (CCPP) received the gold award in the "Fast-Track Power Plant of the Year" category at the Asian Power Award 2012, thereof, this is the first time a Vietnamese company has been given this pretigious award.
                                               
The Asian Power Awards, dubbed as the 'Oscars' of the power industry, is organized annually to recognize top achievers in the region as they unceasingly strive for quality and excellence in their own categories.
                                                                          
Nhon Trach 2 CCPP started commercial operation in Vietnam on October 16, 2011 after a fast track construction period of only 28.5 months, which is 1.5 months earlier than the contract time schedule. According to the report of Petro Vietnam Power Nhon Trach 2 Joint Stock Company, this project has gained 4 “best”: the safest, the most effective, the shortest construction schedule and the most economical. This is the result of the outstanding cooperation between all parties involved in the project on the part of Lilama, Petro Vietnam Power Nhon Trach 2 Joint Stock Company and Siemens.

 With an installed capacity of approximately 750 megawatts (MW) at a plant net efficiency of over 57 percent the Nhon Trach 2 Power Plant is now making an eco-friendly contribution toward alleviating the country's power shortages. Thanks to advanced Siemens burner technology the plant’s nitrogen oxide emission at full load on gas is very low at 25 ppm (parts per million) or less.This power plant also tops the contractually warranted figures both for power output and electrical efficiency and also in terms of lower emissions. This power plant thus sets new power quality benchmarks for Vietnam's power industry.
Using modern technologies, Nhon Trach 2 CCPP has achieved the highest efficiency of all thermal power plants of Vietnam with high stability, safety, usability as well as environmental-friendliness. The plant will make a positive contribution to ensure the electricity safety of Vietnam in the coming years, especially in the dry seasons.
                                                   

                                                                                                  
 Siemens supplied the power block comprising main components such as gas turbines, heat-recovery steam generators, steam turbine, generator, and instrumentation and controls, and completed this scope three months ahead of the agreed date

                                                                    
Up to now, Nhon Trach 2 CCPP has contributed 5 billion kwh electricity to the national power grid. In the first 9 months of 2012, the plant has achieved 3.2 billion kwh, meeting the assigned plan given the difficult economic times as well as the harsh situation of electricity production. In 2011, the contribution was over 1.7 billion kwh, 17 days ahead of schedule and 17% exceeding the planned total productivity of 2011, attributing to the reduction of electricity shortage in the dry seasons of 2011.

Vietnam is one of the fastest growing countries in Southeast Asia with a pronounced increase in its power demand at around 11 to 13 percent per year. The installed electrical capacity nationwide is approximately 21 gigawatts that can accommodate 10 percent of the overall demand only. Therefore, the commercial operation of Nhon Trach 2 ahead of the schedule could be seen an outstanding achievement of all related parties, especially Siemens Energy. After Phu My 2-1 Extension, Phu My 3, Ca Mau 1&2, this is the fifth combined cycle power plant that Siemens has successfully implemented thus reassuring its leading position in this field in Vietnam.
  
Facts & Figures
 
  • World record: In 2002, the combined cycle power plant built by Siemens in Mainz-Wiesbaden achieved an efficiency of 58 percent and set a world record.
  • In May 2011, Siemens set another world record in combined cycle power plant technology in Irsching, Bavaria. At the Ulrich Hartmann power plant, an efficiency level of 60.75% at a capacity of 578 MW was achieved during the commissioning of unit 4.
  • Climate protection: The new SGT5-8000H gas turbine with a capacity of 375 megawatts sets new standards for climate-compatible, highly efficient and quickly available power generation for the future. This innovation increases the efficiency of combined cycle plants to over 60 percent. Compared with previous power plant technology, this reduces CO2 emissions by 40,000 metric tons a year – which is equivalent to the emissions of 10,000 middle-class cars driven 20,000 kilometers a year.

  • Climate protection: With CO2 emissions of around 330 grams per kilowatt-hour, modern combined cycle power plants are among the most environment- and climate-compatible fossil-fueled plants in the world. On average, power plants worldwide emit roughly 578 grams of CO2 per kilowatt-hour. (Source: Siemens)
