Materiality 2025
Materiality Identification Process (GRI 3-1)
In 2025, CKPower conducted a Materiality Assessment to identify key sustainability issues relevant to its business, following an annual review process aligned with the Global Reporting Initiative (GRI) Standards. This year, CKPower adopted the Double Materiality approach under the GRI Standards 2021, considering both the impact dimension and the business dimension, covering the following issues:
Inside-Out Impact – How CKPower’s business activities affect the environment, society, and stakeholders.
Outside-In Impact – How sustainability factors influence CKPower’s business operations and financial performance.
Evaluating Both Positive and Negative Impacts – Including business opportunities and risks.
The Materiality Assessment process integrates Sustainability Impact and Financial Impact evaluations while considering value creation for all stakeholders. Human rights considerations are also incorporated into the assessment framework.
To ensure credibility and transparency, CKPower consulted external experts in the energy sector and sustainability during the assessment process. Furthermore, this report has undergone independent external assurance to verify the accuracy and reliability of the materiality assessment.
The sustainability material topics disclosed in this report have been approved by the Board of Directors, the Corporate Governance, Risk Management, and Sustainable Development Committee, and senior management. CKPower follows a five-step Materiality Assessment process, as outlined below:

Step 1: Identifying Sustainability Issues in the Organizational Context
The Company considers various internal and external factors related to its business operations, including strategy, vision, objectives, and facility locations, as well as global and industry trends, risks, and opportunities that may impact future sustainability efforts. The assessment also incorporates universal human rights principles and historical events to analyze key and supporting activities throughout the value chain. This process helps identify stakeholder groups directly and indirectly affected—both positively and negatively—by the Company’s operations. The value chain impact analysis results are detailed in Section 3 of the Annual Report 2024 (Form 56-1 One Report). Following this, the Company determines material sustainability issues that influence its long-term sustainability across environmental, social, governance, and economic (ESG) dimensions. The 2024 material topics were reviewed alongside the aforementioned internal and external factors. Additionally, the Company benchmarked its sustainability priorities against those of other companies within the same industry at both national and global levels.
This benchmarking includes assessments from:
- Morgan Stanley Capital International (MSCI) ESG Ratings,
- S&P Global Corporate Sustainability Assessment (CSA),
- Sustainability Accounting Standards Board (SASB),
- Sustainalytics ESG Risk Ratings,
- SET ESG Ratings by the Stock Exchange of Thailand
- FTSE Russell
- United Nations Global Compact (UNGC) and Sustainable Development Goals (SDGs)
- International Hydropower Association (IHA)
- World Economic Forum (WEF) Global Risks Report 2025 (10-year risk ranking)
To ensure a comprehensive analysis of material sustainability issues, the identified material topics were used to assess impacts on stakeholders throughout the value chain.
Step 2: Assessing Actual and Potential Impacts
CKPower identified both positive and negative impacts that have occurred and may potentially occur in the future (Actual and Potential Impacts) for material sustainability topics across environmental, social, governance and economic dimensions. The assessment also considered whether such impacts are short-term or long-term in nature. In addition, human rights impacts throughout the Company’s value chain were taken into account, covering both primary and supporting activities of the organization. This process was undertaken to identify relevant stakeholders for the development of the stakeholder engagement process.
Step 3: Stakeholder Engagement and Impact Validation
CKPower engages with key stakeholders to validate the impact of its business operations across environmental, social, governance, and economic aspects, as well as human rights considerations. This included gathering perspectives, expectations, and concerns related to the Company’s business operations and incorporating them into the formulation of strategies and material sustainability topics relevant to the business. Stakeholder engagement was conducted through various channels, including focus group discussions and questionnaire surveys administered by an independent external organization. The information and feedback obtained from stakeholders were analyzed to identify associated impacts, risks, and opportunities related to business operations, and were also used as supporting information for the assessment and prioritization of Material Topics.
Step 4: Prioritization of Material Sustainability Topics
The assessment categorizes impacts into two types:
Financial Impact: Evaluating risks and opportunities associated with material sustainability topics that could affect profitability, business continuity, and shareholder value. Proactive management of these issues can unlock new business opportunities and drive long-term value creation.
Sustainability Impact: Assessing both positive and negative impacts of the Company’s operations on the environment, society, and stakeholders in the value chain.
Following this, CKPower establishes qualitative and quantitative criteria for assessing sustainability impacts, including:
- Scope – The extent of the impact.
- Scale – The magnitude of the effect.
- Remediability – The ability to mitigate or reverse the impact.
- Likelihood – The probability of occurrence.
This covers both financial and sustainability impacts by determining the magnitude of impact and the likelihood of occurrence in order to prioritize issues and establish appropriate strategic management measures from both sustainability and financial perspectives. The Company conducted a Materiality Validation process by evaluating the aggregated sustainability impacts on stakeholders (criteria at levels 4 and 5) and considering financial impacts at level 3. The assessment encompassed the impacts of each material topic across past and present occurrences, as well as potential future impacts, taking into account both positive and negative aspects.
Furthermore, the Company classified the issues into Material Topics and Business Fundamental Topics for expert review, including peer benchmarking against companies within the same industry, before submitting them to senior management for approval.
Step 5: Reporting, Review, and Continuous Improvement
CKPower has established plans and operational guidelines to mitigate the negative impacts of its Material Topics and Business Fundamental Topics. As part of the materiality assessment process, the results were presented sequentially to Executive Management, the Sustainability Steering Committee, the Corporate Governance, Risk Management and Sustainable Development Committee, and the Board of Directors for consideration and approval prior to disclosure. The Company also ensures regular reviews of the process and provides continuous disclosure in its Sustainability Report. This enables the Company to reassess impacts and determine appropriate management approaches in response to the evolving environmental, social, and economic conditions each year.
CKPower Materiality Topics 2025 (GRI3-2)
The analysis of impacts on stakeholders and the prioritization of material sustainability topics enabled the Company to identify and conclude a total of 14 sustainability topics that are significant to the business, covering the economic, social, and environmental dimensions. These are categorized into two main groups as follows:
- 9 Material Topics
- 5 Business Fundamental Topics
Materiality Topics
Issues with significant impacts on CKPower’s sustainability performance and business operations, requiring active management and strategic focus. In addition, they encompass the issues of greatest concern to stakeholders in the current year, totaling nine topics.
Business Fundamental Topics
Essential topics that CKPower must manage in compliance with regulations, industry standards, and best practices to ensure operational efficiency. These topics are aligned with applicable regulations and general practices at both national and international levels. In the absence of these fundamental topics, the Company may be unable to operate efficiently and effectively, and may not achieve its short-, medium-, and long-term objectives. Effective and continuous management of these fundamental topics is a key driver in advancing the business toward sustainability and growth within the renewable energy industry. CKPower is committed to implementing comprehensive actions to deliver tangible outcomes and achieve genuine, long-term success. In total, there are five Business Fundamental Topics.

Changes in Material Topics Compared to 2024
In 2024, CKPower identified a total of 14 sustainability topics. In 2025, the Company restructured its sustainability topics to better align with CKPower’s Sustainability Strategy (2022–2026), which consists of five core strategies, categorizing them into:
- Materiality Topics: 9 topics
- Fundamental Business Practice Topics: 5 topics
This restructuring was undertaken based on stakeholder feedback and executive discussions, leading to the addition of three new materiality topics, namely:
- Corporate Governance – to strengthen corporate governance practices and transparent disclosure to stakeholders throughout the value chain, reinforcing CKPower’s commitment to renewable electricity generation under responsible governance.
- System Reliability and Availability – to reinforce stakeholder confidence by ensuring stable operations and the continuous readiness of electricity generation and supply to customers and the power system.
- Supply Chain Management - to enhance the systematic management of suppliers and contractors in alignment with the Company’s improved operational processes, covering key supplier stakeholders.
Other topics have been reclassified as fundamental business topics, ensuring that CKPower’s sustainability practices remain aligned with its business operations.
