The turbines were functional throughout the process and did not disturb operations, says Thorbjorn Fors, senior vice president at Siemens Energy and managing director of Asia Pacific. PacificLight and Siemens Energy had agreed to the upgrade in March 2021, which marked the first ATEP agreement in Asia.
An upgrade to PacificLight Power’s gas-fired power plant in Jurong Island has reportedly boosted its total output by 30 megawatts (MW) and made the plant the first in Singapore to surpass 60% efficiency. The firm claims this will eliminate over 60,000 tonnes of carbon emissions annually — the equivalent of taking 9,300 cars off the road.
Siemens Energy delivered the Advanced Turbine Efficiency Package (ATEP) upgrade in two phases; the first was completed in 2023 and the second was completed in February. The upgrade involved installing new hot gas path parts, advanced profiling and aero features, ultra-efficient internal cooling and sealing, and optimised stage loading, among others.
