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 modern, higher-efficiency gas-fired plant, and this will reduce
carbon dioxide emission by more than 60 percent. 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.
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
megawatts (MW) to 450 MW, with efficiency of over 62 percent 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.
