Water Resource Management

Water is a critical resource for CKPower’s business operations because over 80% of its electricity production is attributed to hydroelectric power plants. As such, the Company develops management plans to maintain appropriate water levels in reservoirs and assesses risks brought about by seasonal variation in rainfall to formulate water management plans to ensure sufficient water levels for electricity production all year round.

An example of these initiatives is the main inlet valve (MIV) adjustment project, which enhances production efficiency by reducing loss of water, which is one of the costs in power production. The project saves approximately THB 7 million in maintenance expenses upon each equipment malfunction. In addition, as combined cycle power plants require an enormous amount of water in power generation, the Company has placed emphasis on water management for maximum efficiency to avoid the risk of water shortage.

The adjustment of chloride range in the cooling towers in BIC 1

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 80,000 cubic meters per year and saved over THB 3 million in costs, achieving the 2020 goal of reducing 30,000 cubic meters of effluent and setting a new target for 2021.

Waste management

CKPower has placed emphasis on reducing both hazardous and non-hazardous waste from business operations and has thus created waste management protocols in order to serve as guidance for the controlling and management of waste generated by the Company’s business operations, products, and services as well as to ensure that all types of waste are managed correctly and appropriately according to relevant regulations. The protocols also cover all waste produced by contractors and operators in the Company’s supply chain. Furthermore, CKPower conducted training on waste management for its employees, such as a training program for employees residing around the Xayaburi Hydroelectric Power Plant, as well as checked whether the participants were able to dispose of waste properly and monitored environmental impacts of the Company’s waste management. It was found that those living around the plant gave full cooperation in sorting waste at the source, enabling the Company to dispose of each type of waste properly.

Waste Management Training for Residents around the Xayaburi Hydroelectric Power Plant

CKPower held training for a total of 192 residents around the Xayaburi Hydroelectric Power Plant to educate them on sorting and eliminating each type of waste as well as the 3Rs (Reduce, Reuse, and Recycle) in order to foster understanding and ensure proper practice. The Company also kept track of whether the residents were able to dispose of waste correctly. The 2021 target is to reduce the amount of general waste per capita by 20%.

Reduction of Gas Compressor Lubricant Use

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.

Paper-X Project (Waste paper segregation)

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.

Bottles…in Exchange of…Happiness” Campaign

In order to create jobs and generate income for the residents of Chak Daeng Temple Communities, promote waste separation in the Company, and restore value to used PET bottles, the Bottles in Exchange of Happiness campaign aimed to collect 88 kilograms of PET bottles to produce fibers for the production of monk robes. After the launch, the campaign drew tremendous attention and overwhelming feedback, enabling CKPower to collect as much as 348 kilograms, equivalent to 18,702 PET bottles in only nine weeks. The collected PET bottles were transformed into 1,390 sets of monk robes, almost four times more than the target.

“Separate Bottles to Help Doctors” Campaign

Aiming to contribute 100 PPE suits, which required 1,800 clear PET bottles, CKPower collected PET bottles and sent them to Indorama Ventures Public Company Limited (IVL), the donation hub of the Separate Bottles to Help Doctors Campaign. CKPower was able to collect a total of 73 kilograms of PET bottles, which were transformed into as many as 190 PPE suits, in only five weeks, reducing greenhouse gas emissions by 67% and saved energy otherwise consumed by 79%.

Air Quality

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 2020 found that the air quality of the power plants was above the standards required by the law.
