Fuel Usage Management
To reduce emissions in line with regulatory requirements, power plants need to add environmental protection equipment and facilities. Coal used must be high in calorific value, low in ash, and low in sulfur content. Since the properties of coal vary from mine to mine and country to country, power plants use blending methods to meet a power plant's requirements for coal ash, calorific value, and sulfur. Taipower has added additional quality requirements for its coal procurement. Further restrictions on mercury content have been imposed. While Taipower exercises strict control of emissions from downstream power plants in its supply chain, the Company works even harder to deliver on its commitments to upstream areas of its supply chain.

Enhancing the Energy Efficiency of Taipower's Operations
Management of Productive Resources
Taipower's primary sources of greenhouse gas emissions included thermal power generation, coal storage yards, fuel-consuming equipment such as vehicles and engines, insulation gas for power switches, and refrigeration and air-conditioning equipment. Although there are no emission or disclosure regulations in Taiwan, the Company's has taken the initiative to limit greenhouse gas emissions by inviting relevant units to conduct inventories and internal verifications each year. Moreover, a third-party notary unit is invited to carry out external verification of thermal greenhouse gases and to publicly disclose the Scope 1 greenhouse gas emissions of Taipower and its thermal power units (coal, fuel, and gas). In 2022, emissions totaled 98.48 million tons of CO2e.

Non-Productive Resource Management
In 2022, Taipower gave impetus to power-saving in conjunction with the Executive Yuan's Electricity Efficiency Management Plan for Government Agencies and Schools by setting a goal of zero growth in annual power consumption compared to the previous year. Moreover, in accordance with the Ministry of Economic Affair’s Water Saving Normalization Action Plan, Taipower promotes water conservation. The General Management Office will coordinate these efforts while other branches and power plants will be driven through promotions to implement various measures that constituted a comprehensive energy-saving and carbon-reduction scheme. Taipower will also track its energy consumption (paper, water, power, fuel) on a monthly basis and conduct annual assessments to select units with excellent performance.

Taipower's Non-Productive Water Consumption
Results of Non-Productive Resource Management
- Prioritizing the use of equipment with water efficiency labels was the first priority along with the effective use of rainwater resources (toilet flushing, watering plants) to reduce tap water consumption
- In line with the Water Saving Normalization Action Plan, Taipower actively promoted the installation of water-saving equipment and replacement of old, water-consuming equipment in offices, at construction sites, and in employee dormitories
- Promote water-saving measures at each unit such as water-saving advocacy, water management, pipeline facility leak inspection, and rainwater reclamation and reuse
- Prioritizing the purchase of appliances with an energy-saving labels or in the first or second class of energy efficiency
- Establish an energy management system to monitor and analyze electricity consumption data. Identify improvement items and plan solutions to improve energy efficiency
- In cooperation with the Electricity Efficiency Management Plan for Government Agencies and Schools, Taipower actively promoted the replacement of old energy-consuming equipment (air conditioners, lamps, etc.) in each unit to enhance electricity efficiency
- Indoor temperatures were kept between 26-28°C in each office and combined with circulating fans to increase comfort levels while reducing the use of air conditioning
- Energy-consuming equipment and business machines were operated in all offices in an energy-saving manner; for example, the power supply for water dispensers was turned off automatically during off-hours and on regular holidays to save standby power
- Promoted ride-sharing measures in vehicle dispatching and reinforced vehicle maintenance and inspection to reduce fuel consumption
- Drew up a budget to accelerate the replacement of old fuel-consuming vehicles and made good use of electric vehicles
- Fuel consumption in the past three years: In 2021, due to the impact of the epidemic, the usage rate of public vehicles was reduced, so the fuel consumption in 2022 was slightly higher than in 2021 by 340 liters. Despite this, fuel consumption in 2022 was 5,196 liters lower than in 2020.
- Continued to implement paper-reduction measures such as the electronic exchange of official documents and online approvals, with performance reaching 70% and 85%, respectively.
- Advocated for employee use of double-sided printing to save 2.82 million sheets of paper
