The scope of supply includes four SGT6-9000HL gas turbines, as well as generators, steam turbines, condensers and associated auxiliary equipment. The plant will deploy Siemens Energy’s HL class gas turbine technology, designed to achieve high efficiency across a broad operating range. This enables faster start up and more responsive load adjustment, allowing the plant to adapt to fluctuations in electricity demand and support system dispatch under changing generation conditions.
Once commercially operational, carbon dioxide emissions per kilowatt hour are expected to be reduced by approximately 58 percent compared with the existing coal fired units.
“The Mai-Liao project is an important step in modernizing Taiwan’s power infrastructure and supporting the transition to lower carbon power generation,” said Chien Hao Lee, Managing Director of Siemens Energy Taiwan. “As power systems evolve, there is increasing demand for highly efficient and flexible generation assets capable of stable long term operation. Siemens Energy is honored to contribute to this project and, through our technology and long-term service capabilities, to support Taiwan’s energy transition.”
Siemens Energy has been involved in multiple energy infrastructure projects in Taiwan and has supplied gas turbine technology, key equipment and services to several combined cycle power plants across the island. Mai-Liao project’s two units are scheduled to enter commercial operation by December 31, 2029, and will be integrated into Taipower’s dispatch system. Once fully operational, the plant is expected to generate approximately 14 billion kilowatt‑hours of electricity annually, accounting for around five percent of Taiwan’s total power generation.
