Identification of Material Topics
In compiling each annual report, Taipower takes into account the key sustainability reports on the power industry for that year and the previous year, and incorporates them into the materiality reference at its discretion. Taipower's materiality analysis in 2023 was conducted according to the 2021 GRI Universal Standards and AA 1000 SES, and referenced international sustainability trends by comparing important sustainability reports of the power industry in various countries in the current year and previous year, as well as the latest industry materiality map released by the SASB. Taipower integrated material issues of the power, solar power, wind power, and biomass fuel industries, and took them into consideration when selecting sustainability topics. Ultimately, 22 sustainability issues were selected. Based on the double materiality principle proposed by the EU, which uses actual/potential and positive/negative impact as the criteria and dimensions, Taipower verified 11 material sustainability issues.
To identify the material topics of concern to stakeholders, Taipower refers to the GRI Standards to conduct materiality analysis that reviews and identifies the key material topics for the Company. In 2023, Taipower additionally sought to identify material topics by surveying stakeholders. Survey results were collected from 228 Taipower employees (including 39 senior executives) and 235 other stakeholders for a total of 463 responses.
Identification Process for Material Topics
- Review of sustainability issues identified in the previous year
- Examine relevant major sustainability trends at home and abroad, such as amendments to SASB and domestic regulations
- Examine Taipower's management issues, benchmarks in the electrical industry, opinions of internal and external stakeholders, and major news events
- Identified 22 sustainability issues
- The possible impact of various issues on Taipower and the degree of influence on different stakeholders are determined through a questionnaire
- 68 senior executive questionnaires were used to understand the importance of issues to business operations
- 463 questionnaires were collected from various other stakeholders
- Confirm the material topics matrix through materiality product sorting and Taipower's internal engagement
- Determine the structure and content of the Taipower Sustainability Report based on the analysis results

Positive Impact and Occurrence Possibility Matrix
Negative Impact and Occurrence Possibility Matrix
With the help of the material topics matrix Taipower has summarized the materiality of various sustainability issues. The Company sorted the issues based on the X, Y axis of each topic. 11 material topics that fall within the scope of this report were identified through communications with stakeholders.
Correspondence between stakeholders and the theme of sustainability
Note: The field of "Location of economic/environmental/social impact" only partially lists stakeholders. Other stakeholders who, after evaluation, were determined to not directly cause ESG impact were omitted.
