Siemens Energy supplying two Chinese power plants

Siemens Energy will deliver four H-class combined cycle power units for power plants in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) in southern China.

The separate deals with Guangdong Energy Group Co., Ltd. and Shenzhen Energy Group Co., Ltd. involve new and updated power plants and will help meet the growing power demand in the region. The projects also mark the sale of the 100th SGT-8000H gas turbine.

Under the agreement with Guangdong Energy, Siemens Energy will deliver a 675 MW combined cycle power generation unit, including a SGT5-8000H gas turbine, a steam turbine, two generators and related auxiliary equipment, and long-term maintenance service for the plant in Guangzhou owned by Guangdong Yuehua Power Co., Ltd. The existing coal-fired power plant will be transformed into a higher-efficiency gas-fired plant, and this will reduce carbon dioxide emission by more than 60%. The plant will generate 2.3 billion kilowatt-hours of power annually and is expected to go into commercial operation in mid-2023.

The agreement with Shenzhen Energy includes supplying three H-class combined cycle power units for the Phase II project at Dongbu power plant and the upgrade project at Mawan power plant. The scope includes three SGT5-8000H gas turbines, three SST-5000 steam turbines, three SGen5-3000W generators, and auxiliary systems. The two projects, both located in Shenzhen, are scheduled to go into operation by the end of 2023 and in mid-2024 respectively. The annual total power generation of the two plants is expected to exceed six billion kilowatt-hours.

“We’re achieving a significant milestone with the one-hundredth H-class gas turbine sold,” said Karim Amin, member of the Executive Board of Siemens Energy AG. “We’re proud to see that our strategic partnerships with Guangdong Energy and Shenzhen Energy are now bearing fruit: We’ll be working together to make tangible contributions to the Greater Bay Area and the low-carbon development of China.”

With a population of over 70 million, the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) is among the most dynamic regions in China. According to Siemens, GBA aims to grow into a global sci-tech innovation center and a role model of sustainable development for the country. In December 2019, Siemens Energy and Shenzhen Energy forged a strategic partnership in the areas of R&D and smart and green energy.

With 88 turbines in operation on four continents and over 2.5 million operating hours, the SGT-8000H is the market leader in its class. Since its launch, the output rating of the gas turbine has grown from 375 MW to 450 MW, with efficiency of over 62% in combined cycle operation. The turbine’s high combined cycle efficiency, low NOx emissions, and industry-leading operational flexibility – which includes load-following capability of up to 80 MW/minute – make the turbine ideal for a wide range of applications, from simple cycle peaking and combined heat and power (CHP) to baseload power plants. The SGT-8000H is also capable of hydrogen co-firing, which reduces its CO2 emissions even more.
