Water Resource Management

Water is an important resource for CKPower’s business operations, as more than 80% of its electricity generation is attributable to hydroelectric power plants. Therefore, the Company has developed innovations to increase the efficiency of electricity generation and reduce the loss of water, which is an important resource.

As the power generation process of the cogeneration power plant requires a large quantity of water, in order to reduce the risk of water scarcity, CKPower places great importance on water management to maximize efficiency. For the cogeneration power plant (BIC), the use of water in the production process has been reduced by implementing a method of production that utilizes recirculated water in a closed system.

CKPower has also established a process for monitoring the water level in the source reservoir and promoting water conservation in conjunction with communities and agencies in Lao PDR in order to reduce the potential impact of water scarcity and maintain sufficient water for the consumption of all sectors from upstream to downstream.


In 2020, CKPower’s combined cycle power plants consumed approximately 2 cubic meters of water in the production of electricity and steam. In terms of water management, the Company recorded data on water usage and organized projects and activities that would decrease water consumption and enable it to plan water utilization in the future, such as the adjustment and control of the chloride range in cooling water, which improved water use efficiency and reduced loss by recycling wastewater. The project reduced the amount of effluent generated by the cooling towers and the water added to the cooling systems by more than 58,500 cubic meters per year and saved over THB 2.7 million in costs, achieving the 2021 goal of reducing 30,000 cubic meters of effluent and setting a new target for 2022.

Waste Management

With awareness of the problems that may arise from the waste produced by its business operations, which may have both direct and indirect environmental and social impacts, CKPower is, therefore, determined to manage waste by reducing waste production at the source by establishing regulations for waste management as a guideline for controlling the production and management of waste as a result of its manufacturing activities or services in order to ensure that all types of waste generated are handled properly and appropriately in accordance with relevant requirements.

Recognizing direct and indirect environmental and social impacts of its waste management, CKPower strives to reduce waste at the source and has thus established refuse and waste management protocols to serve as guidance for the control and management of waste generated in its production or service activities and ensure that each type of waste is managed correctly and appropriately in compliance with relevant regulations.

Waste Management Training and Education Programs

CKPower has provided training to educate employees on waste management, such as training for employees residing near the Xayaburi Hydroelectric Power Plant, as well as conducted inspections on proper waste disposal following training and monitored the environmental impact of waste management. After the training, it was found that employees living in the vicinity of the power plant cooperated very well in sorting waste at the source prior to passing it on to the Company for proper disposal by waste type.

Within the facilities themselves, CKPower and Bangpa-in Cogeneration Power Plant conducted an activity to foster knowledge and understanding about different types of waste and how to properly manage, sort, and return each to the recycling/reuse process and instill awareness on waste reduction by organizing training on “Putting Trash in the Right Bin, Doing the Right Thing for the Earth” to educate the executives and employees on the importance of proper waste sorting as well as how to properly dispose of waste according to the categories of waste bins provided by the Company. Fifty-seven percent of all employees attended the training. In addition to providing training to personnel within the organization, CKPower also places great importance on waste management for communities surrounding the power plants. Among these was a training session for 192 residents in the vicinity of the Xayaburi Hydroelectric Power Plant on the different types of solid waste and the method for sorting and disposing of each type as well as the 3R principles—Reduce, Reuse, and Recycle—in order to foster understanding and enable proper implementation. CKPower also monitored the outcomes of the training to ascertain whether attendees were able to properly implement waste disposal strategies

Energy-Saving Program in the Office

CKPower and its subsidiaries have communicated and publicized the office energy- and water-saving program to all executives and employees in order to instill awareness on the value and efficient use of resources and different methods of implementation via email and company intranet as well as developed a manual on energy saving in the office to promote awareness, implementation, and cooperation in conserving energy and resources within the office. Energy saving campaign is widely promoted to encourage employees to switch off lights, to unplug and turn off electrical appliances after every use, and to use water economically. The objectives of the program are as follows:

  1. To reduce the cost of electricity and water in the office
  2. To reduce the use of electricity and water in the office
  3. To reduce global warming
  4. To instill awareness and encourage participation among employees in the program as well as in the value and efficient use of resources
  5. To reduce the use of electricity and water in the offices of the Company and its subsidiaries by 10% compared to the previous year.

Long-term goals for the next 3-5 years

  1. Collect data on the electricity and water consumption of both CKPower and its power plants for 5 years in order to analyze the results and trends of electricity and water usage
  2. Modify resource consumption behavior and opt for energy-efficient and eco-friendly office equipment
  3. Instill awareness of efficient use of electricity and water

Based on an analysis of CKPower’s electricity consumption data compared to last year, it was found that the Company and its subsidiaries were able to reduce electricity consumption by 801.20 mWh, equivalent to THB 432,589.30, and reduce the use of water compared to the previous year by 21.34 megaliters, which amounts to THB 5,598.25 saved.


Bangpa-in Cogeneration Power Plant has undertaken the improvement of its machinery lubrication injection system to increase efficiency and match the actual consumption level, thus significantly reducing the amount of lubricant used and hazardous waste generated. In 2020, the power plant effectively reduced the amount of lubricant used and hazardous waste produced by approximately 7,200 liters per year, thus saving around Baht 209,000 per year in cost of lubrication and waste oil disposal.

Waste Sorting Bin Program

CKPower and Bangpa-in Cogeneration Power Plant have placed waste sorting bins in its offices ensure that each type of waste is properly sorted and can, thus, be entered into the recycling/disposal process appropriately and used to create further value. The following six categories of waste bins have been placed at various points within the offices: 1) odorless general waste 2) paper 3) recyclable plastic 4) hazardous waste 5) infectious waste 6) wet waste. The weight of each type of waste is recorded as comparison data for determining the reduction of waste in the future, and employees are encouraged to learn how to separate waste at the source. To this end, knowledge and understanding of the types and proper sorting of waste have been instilled in employees and executives through the training activity on "Putting Trash in the Right Bin, Doing the Right Thing for the Earth," and training materials have been published via the CKPower Academy mobile application.


To reduce waste and maximize paper recycling and reuse, CKPower launched the Paper-X Project with the goal of reducing 1,000 kilograms of waste paper. Waste paper was divided into three types: 1) white paper, 2) cardboard/brown paper, and 3) others, so that it could be recycled and distributed to schools around CKPower’s power plants for further use. The results showed that the project enabled the employees to sort waste paper correctly, reduced the consumption of resources in paper production, and supported the education of the students in the vicinity of CKPower’s power plants. In 2021, CKPower was able to enter a total of 1.3 tons of sorted used paper into a proper recycling process, which was produced into 25 reams of paper to be distributed to the schools around its power plants, valued at THB 2,250 at the price of THB 90 per ream, amounting to 0.98 trees, 402.50 liters, 21.85 liters of fuel, and 230 KWh of electricity saved.

Waste Reduction Program

Recognizing the significance of waste reduction at the source and resource maximization according to the 7R’s (Reduce, Reuse, Refill, Return, Repair/Repurpose, Replace, and Recycle), CKPower initiated this project by stopping giving out plastic bags in convenience stores in its power plants and encouraging employees to use tote bags instead as well as replacing Styrofoam boxes in the canteens with paper containers. From the beginning of the project in April to December 2021, CKPower successfully reduced 16,800 plastic bags and 5,460 Styrofoam boxes.

PET Recycling Project

To promote waste sorting, create jobs and generate income for the residents of Chak Daeng Temple Community, and restore value to used PET bottles, CKPower launched this program and successfully collected 120 kilograms of PET bottles, equivalent to 5,400 bottles, which were transformed into 6,600 face masks and generated THB 133,000 in revenue for the Chak Daeng Temple Community.

Color Printing Reduction Program

To encourage employees in the organization to consider the necessity of resource consumption prior to actual use and to take part in saving and using resources efficiently, CKPower has promoted the reduction of unnecessary printing of color documents, including transitioning from the use of documents in hard copy to the use of electronic documents (e-documents). However, the implementation of this initiative by all agencies must not contravene laws and regulations on operations, such as accounting standards. As a result of this initiative, CKPower and its subsidiaries were able to reduce color document printing compared to the previous year by 32.9%, or equal to a saving of 478,834 baht.

AIR QUALITY Management

More than 80% of the power produced by CKPower is derived from hydroelectric and solar power plants, which rely on renewable energy and therefore do not involve the burning of fossil fuels or emission of air pollutants. On the other hand, the Company’s co-generation power plants utilize natural gases, which release air pollutants. Therefore, the Company has placed great emphasis on controlling and inspecting the air quality and the emissions of pollutants from its power plants that may affect communities and the environment in the vicinity. To this end, CKPower has employed various cutting-edge emission control technologies and regularly monitor and inspect the air quality at the chimneys and other areas across the properties. The results of the air quality testing according to EIA standards in 2021 found that the air quality of the power plants was above the standards required by the law.


Nature provides habitats for living organisms and is the origin of various resources vital to the existence of humanity Biodiversity is thus one of the indicators that reflect the health of the environment and ecosystems. It is undeniable that advances across different dimensions of modern life have had extensive impact on biodiversity, leading to the destruction of natural resources, extinction risks for certain plant and animal species, as well as loss of wildlife habitats. CKPower is thus committed to environmental and social responsibility in its business operations and recognizes the significance and benefits of biodiversity, with a vision that seeks to deliver energy security on the path of sustainability.

In 2021, the 15th session of the United Nations Convention on Biological Diversity (COP 15) was held, during which it was argued that healthy ecosystems are one of the keys to mitigating the problem of climate change and helping communities adapt to living with its effects. From this meeting, it is likely that the UN will mandate NGOs around the world to compile reports in accordance with the Taskforce on Nature-Related Financial Disclosure (TNFD) in order to fulfill Sustainable Development Goal (SDG) 15, which will directly affect the business sector. CKPower recognizes the importance of maintaining ecological balance and biodiversity, especially in the business of hydroelectric power plants, to which the Company has applied modern technology to strictly prevent and mitigate impact on biodiversity, such as by designing the first run-of-river power plant on the lower Mekong and implementing world-class technology to design multi-system fish passage facilities. In doing so, the Company aimsto take part in the social initiative to preserve biodiversity, food security, and the livelihood of those who live in the vicinity of its power plants as a good neighbor to the community.

CKPower is committed to environmental and biodiversity management in compliance with applicable laws and regulations and seeks to control, prevent, and minimize environmental impacts by utilizing resources sustainably as well as restoring and maintaining biodiversity, with emphasis on preventing pollution at the source. The Company also promotes the adoption of cutting-edge, efficient, and environmentally-friendly innovation and technology in its business operations. CKPower also promotes community development and prioritizes listening to opinion of communities and stakeholders in accordance with the principles of human rights. It also engages and discusses with stakeholders directly impacted by its operations and relevant agencies in the development of its projects to minimize impacts on the ecosystem.

CKPower also communicates with its executives and employees to foster understanding and raise awareness on biodiversity as well as promotes technology transfer among those relevant in order to review and improve the Company’s environmental management process and regularly elevate its environmental management and quality control.

Therefore, CKPower thoroughly conducts environmental impact assessment for every project and prescribes preventive measures and solutions covering physical, biological, and biodiversity aspects. The Company also carries out activities as part of biodiversity management throughout the process, from designing to the development of projects to mitigate impacts on biodiversity (if any), and has set a goal of achieving no net loss of biodiversity as part of environmental impact assessment for all new projects. So far, all projects of the Company and its subsidiaries have compiled EIA reports and none of the them are in conservation zones or world heritage sites
