Siemens has received its first order from China for the delivery of four SGT-800 gas turbines and the associated generators. The turbines will be installed in the Shanxi Guoxin Baode and Xiyang decentralized energy projects in Central China. The two combined cycle power plants with heat extraction will have an overall capacity of 308 megawatts (MW). The customer is Shanxi Natural Gas Limited Company, a subsidiary of Shanxi Provincial Guoxin Energy Development Group Co., Ltd.. Commercial operation of the plants is scheduled for July 2017.
Siemens delivers four gas turbines of type SGT-800 with the 54-MW rating to China. Two gas turbines and two generators are to be installed in a 2x1 combined cycle power plant with heat extraction at each site. Siemens also supplies all associated auxiliary systems as well as installation and commissioning services for the projects. Both combined cycle power plants will be fired with coalbed methane, a form of natural gas from an unconventional gas reservoir with high hydrogen content. The SGT-800 is able to fire this gas due to its high fuel flexibility.
Worldwide 297 SGT-800 gas turbines have been sold and the fleet has accumulated about 4 million operating hours. The efficiency and steam-raising capability of the SGT-800 makes the turbine especially suitable for cogeneration and combined cycle applications. The high reliability and high efficiency of the gas turbine promote both a low life-cycle cost and a small environmental footprint.
According to China’s 12th Five-Year Plan for Renewable Energy Development, China will pay high attention to develop the decentralized energy market, especially fueled by natural gas. Siemens supports these ambitious goals with the delivery of gas turbines for the Shanxi Guoxin Baode and Xiyang power plants.
