By utilizing hydropower as a sustainable energy source, CKPower aligns its strategy with global efforts to achieve a low-carbon society and reinforces its role as a leader in sustainable energy production.
Water Management in Power Plants:
-
Cogeneration Power Plants: Located in the Bangpa-in industrial estate, CKPower’s cogeneration power plants implement efficient water management practices aligned with regulations. The plants operate under water supply agreement with TTW Public Company Limited (TTW), which manages water within the estate. Water is drawn from the Chao Phraya River and treated by TTW before use. Treated wastewater is stored in holding ponds for one day before being discharged into the estate’s drainage canal, promoting reuse and efficient water utilization.
Additionally, Bang Pa-in Cogeneration Plants maintain effluent quality control to ensure compliance with legal requirements and the water quality standards of the industrial estate. This approach guarantees environmentally safe and sustainable long-term water management.
-
Hydroelectric Power Plants: CKPower’s hydroelectric power plants utilize both surface and underground water sources for operational and employee consumption, ensuring optimal water resource utilization. Water is recycled within the facilities before being discharged, with strict controls on effluent quality to ensure compliance with legal requirements and environmental standards
This approach minimizes environmental impact and supports sustainable water management. In the electricity production process, CKPower’s hydroelectric power plants prioritize sustainable water resource utilization to minimize environmental impact. The Company implements regular water quality monitoring and control to ensure compliance with environmental standards. Water usage assessment and monitoring are reported under the GRI (Global Reporting Initiative) framework, promoting transparency and social responsibility.
CKPower also emphasizes on water management in areas with sensitive ecosystems, focusing on minimizing impacts on water resources and the environment. This proactive approach supports sustainable business operations and meets the expectations of stakeholders across all dimensions.
-
Solar Power Plants: CKPower’s solar power plants rely on water supply systems drawn from municipal and surface water sources. The water is efficiently reused within the facilities to maximize resource utilization, with a strong emphasis on water conservation and minimizing excessive usage. This approach ensures efficient operations while supporting environmental sustainability. Effluent quality is closely monitored to comply with legal requirements and environmental standards, ensuring safe discharge practices and environmental protection.
Water management in CKPower’s solar power plants focuses primarily on water usage for cleaning solar panels, which is crucial for maintaining electricity production efficiency. Regular cleaning ensures optimal solar panel performance, contributing to consistent and reliable energy output. In addition, the Company monitors water usage and discloses water management data according to GRI (Global Reporting Initiative) standards to ensure transparency and build stakeholder confidence in the sustainability of its operations.
Through these practices, CKPower demonstrates its commitment to a clean energy transition, sustainable water resource management, and effective climate change response. These initiatives align with the Company’s strategic goal of supporting environmental stewardship and achieving long-term operational sustainability.
Water management performance:
CKPower has implemented measures to optimize water resource utilization and reduce environmental impacts, supporting business sustainability while balancing organizational growth with responsible natural resource stewardship.
Waste Management
CKPower prioritizes sustainable waste management for all types of waste, including non-hazardous waste, hazardous waste, and organic waste, complies with the Hazardous Substances Act (1992), relevant regulations, COP, ERC guidelines, and ISO 14001:2015. In Lao PDR, waste management aligns with ISO 14001:2015 and international environmental standards to minimize environmental impacts and enhance resource efficiency. The Company actively seeks to reduce waste at the source by establishing protocols for managing the waste generated in its activities both in offices and power plants.
To ensure optimal resource utilization, CKPower promotes circular economy principles by encouraging waste reutilization and managing end-of-life waste in compliance with legal requirements and relevant standards, focusing on proper waste segregation, recycling, and safe disposal methods. To foster a sustainability focused organizational culture, CKPower provides waste management training to employees, ensuring proper understanding and implementation of best practices in all operational areas. Through these initiatives, CKPower demonstrates its commitment to sustainable waste management and environmental stewardship.
Waste Management Performance
Air Quality Management
CKPower is committed to rigorous air quality management practices. As 93% of the power that CKPower produces is generated from various sources of renewable energy, such as hydropower and solar power, which do not involve the burning of fossil fuels a 93% of its electricity is generated from renewable energy sources, including hydropower and solar power, which do not involve fossil fuel combustion. As a result, there are no air pollutant emissions from these electricity generation processes, supporting CKPower’s role in reducing air pollution and mitigating climate change impacts.
For the Bangpa-in Cogeneration Power Plant, which uses natural gas with low nitrogen content as fuel, the combustion process may produce thermal nitrogen oxide (NOx). To minimize NOx emissions, CKPower uses Dry Low NOx Burner (DLE) technology, which controls the mixing of fuel and air before combustion, reducing the combustion chamber temperature and lowering NOx emissions by approximately 40-50%. This also enhances fuel efficiency and minimizes resource loss..
To ensure stringent environmental control and regulatory compliance, CKPower has installed Continuous Emission Monitoring Systems (CEMs) at the flare stacks to monitor and measures air quality in real time. The Company discloses air quality information in line with Environmental Impact Assessment (EIA) monitoring measures and reports the measurement results twice a year, ensuring transparency and accountability in its air quality management practices.
