1. Taiwan

As Taiwan continues to advance its low-carbon energy policies, the share of gas-fired power generation rose to 48.1% in 2025, representing an increase of approximately six percentage points from the previous year. Due to the government’s "gas-for-coal" policy, the nation is steadily reducing its reliance on coal-fired power by replacing coal and oil-fired units with highefficiency gas-fired units. According to the national roadmap, Taiwan’s energy mix is projected to be comprised of 54% natural gas, 9% coal, and 36% renewables by 2035. Furthermore, starting in 2027, the government will implement higher standards for natural gas safety reserves and storage tank capacity. This shift is driving the continuous expansion of liquefied natural gas (LNG) receiving, transmission, storage, and power generation infrastructure, which will further enhance grid stability and energy supply resilience. Leveraging CTCI’s extensive track record in engineering, procurement, and construction (EPC) for power plants and natural gas infrastructure, the Group maintains a distinct competitive edge in large-scale domestic power projects. Following the successful acquisition of contracts for the Taipower Tunghsiao Phase II and Talin Power Plant projects in 2025, the Group is actively targeting upcoming expansion plans for LNG terminals, including Kuantang Phase II, Kaohsiung Intercontinental Phase II, Taichung Phase IV, Talin, and Xiehe.
