Siemens Energy led Consortium to Build Taiwan’s 1st Highly Efficient HL-Class Gas Turbines

Siemens Energy together with its consortium partner CTCI Corporation, a Taiwanese EPC company, has been building the Sun Ba Power Phase II Combined Cycle Power Plant for the independent power producer Sun Ba Power Corporation.

This plant will be an important building block in Taiwan’s energy transition, which aims to shift from coal and nuclear power to environmentally friendly gas-fired power plants and renewable energies.

The Sun Ba II plant, located in southwestern Taiwan, would be having an installed electrical capacity of 1,100 MW, and would be fired with regasified liquefied natural gas (LNG).

Moreover, Siemens Energy said that it would also provide long-term service for the plant’s core components.
“We are very excited to contribute to the energy transition of Taiwan with our leading HL-class gas turbine technology,” said Karim Amin, Executive Vice President Generation at Siemens Energy. “This technology offers substantial value for Sun Ba Power Corporation’s project, as it combines high power density with world class efficiencies. As a result, a large amount of electricity can be produced at the lowest possible cost while driving significant CO2 reductions at the same time.”

Since Taiwan must import its entire natural gas requirements as LNG at comparatively high costs, the efficiency of gas-fired power plants has a particularly strong impact on their economic viability.

Sun Ba II has been designed as a multi-shaft combined cycle power plant, in which two gas turbines and one steam turbine each drive its own electrical generator.

The company’s scope of supply includes the plant’s power island, consisting of two SGT6-9000HL gas turbines, one SST-5000 steam turbine, three SGen6-2000P generators, two heat recovery steam generators, and the SPPA-T3000 control system.

The HL-class turbine has been designed with advanced technologies and based on the H-class fleet that has more than two million operating hours.

The service contract includes long-term service over 25 years for both gas turbines, the generators, the steam turbine, and the heat recovery steam generators. It also includes an option for digital service solutions. CTCI Corporation is responsible for the construction and installation, and whole EPC work of the balance of plant.
