Response Measures to Air Pollution
In response to the current public emphasis on air quality, Taipower has established an actionable air pollution management strategy for stationary, mobile, and fugitive sources of emission. The Company is also gradually implementing air quality guarantees through short, medium, and long-term goals and planning. Through the transformation of the power generation structure, thermal power generation has mainly been transformed from coal to gas-fired. The coal-fired units are gradually being replaced by ultra-supercritical units with better power generation efficiency. Older combined gas cycle units are also gradually being replaced by new units that have better generation efficiency. These actions along with various other measures have helped achieve the goal of reducing air pollutant emissions. The emissions of major air pollutants by Taipower in 2018 were far below the regulatory requirements, and emissions fell sharply when compared with 2017.
While embracing water conservation, Taipower has been actively pursuing a goal of zero wastewater discharge. Rainwater collection (at power plants and dormitories) and wastewater reuse projects have been promoted to reduce the use of tap water inside the power plants through comprehensive planning.
Though the implementation of various water-saving measures, the amount of recovered wastewater in 2018 is as follows (Note that FGD wastewater is not reused as it contains a high salt content which is likely to cause equipment corrosion and soil salinization. As such it is not included in the calculation of wastewater volume).
In accordance with Taiwan's "Waste Disposal Act," Taipower established a "Coal Ash Resource Reuse Promotion Taskforce" in 2015. The taskforce is charged with the research and promotion of coal ash use. The taskforce was later expanded to become a "By-product Resource Reuse Promotion Taskforce," which is primarily responsible for coordinating cross-unit collaboration to formulate by-product resource reuse optimization strategies and response solutions, including phase-out strategies in the use of coal ash and gypsum. The taskforce reviews existing coal ash sales regulations at power plants, promotion of green label certification for fly ash and gypsum products and planning of relevant incentive schemes to encourage all units to increase their fly ash use.
The concept of circular economies has received significant attention from the government this year and some businesses have already picked up on this innovative concept and initiated reform in energy resource utilization. Taipower has been actively implementing Assessment and Planning for the Circular Economy for Zero Waste Generation. The Company promotes circular economic activity through the use of the Taipower Material Flow Management Information System. The system screens out products/wastes with large outputs, and combines the information with opinions of scholars and related units at Taipower. After analyzing risk mechanisms and referring to domestic and foreign practices, a representative list of key materials for the circular economy is produced. After further screening out of key materials, the Company evaluates business models for the introduction of the key materials into the circular economy.
The current business model for the planning of various key materials includes five action plans: the Regional Resource Recycling and Rebuilding Model for Inorganic Products, the Product as a Service Model, the Circular Resource Supply Model for Biomass Power Generation, the Product Life Extension Model for Usable Property, and the Industrial Symbiosis Model.
