In response to the low-carbon transition trend of the global energy industry, Taipower is committed to developing high-efficiency generation technologies, adjusting its generation structure, and continuously increasing the proportion of renewable energy to reduce the electricity carbon emissions factor. For thermal power generation, Taipower currently focuses on three main directions:
-
Transformation from coal to gas-fired
Elevated the proportion of gas and continued the pattern of primarily using gas with coal as support in 2022, making the gas ratio higher than that of coal
-
Coal-fired unit upgrades
Gradually replace coal-fired units with ultra-supercritical units with better generation efficiency
-
Gas-fired unit upgrades
Gradually phase out old gas-fired combined-cycle units and replace them with new-type combined-cycle gas-fired units with better generation efficiency

Sulfur Hexafluoride (SF6) Reduction
Sulfur hexafluoride (SF6) is a greenhouse gas with an extremely high global warming potential. After long-term use, the gas gradually escapes into the atmosphere. Nevertheless, as it is an essential insulating material for power equipment it is widely used in Taipower's substation equipment for power generation, transmission, and distribution. In response to this issue, Taipower has continuously promoted reduction methods. Taipower units that manage substation equipment have SF6 maintenance management procedures. Relevant units carry out SF6 reclamation and purification work as part of procedures for overhauling substation equipment. After the equipment is overhauled, the purified SF6 is backfilled into equipment to reduce greenhouse gas emissions. This allows for the recycling of SF6, mitigates climate change problems and achieves the goals of establishing a circular economy and resource regeneration.
