System Reliability and Availability
CHALLENGES
OPERATIONAL GUIDELINES
CKPower and its subsidiaries place great emphasis on their invested power plants and have thus introduced advanced technology to ensure power distribution continuity and efficiency as well as put cost management systems in place to achieve competitiveness and eco-friendliness. The Company also focuses on developing knowledge on engineering and efficient resource management among its employees at all levels and encouraging learning and operational system improvement in order to promote the development of innovation that will further enhance operational efficiency as well as contribute to greater system reliability and availability. CKPower operates three types of power generation and distribution businesses, namely hydroelectric power plants, cogeneration power plants, and solar power plants.
EXECUTION
RELIABILITY AND AVAILABILITY OF POWER PRODUCTION AND DISTRIBUTION SYSTEMS
CKPower recognizes the significance of the reliability and availability of its power production and distribution systems in fostering confidence among its customers. To this end, it focuses on improving the efficiency of its electricity distribution systems to ensure the stable delivery of electricity to all clients of CKPower and its subsidiaries.
In 2019, the Xayaburi Hydroelectric Power Plants and five solar power projects commenced commercial operations, effectively increasing the installed capacity by 1,291 megawatts. This has enabled CKPower to deliver electricity produced from clean alternative energy, strengthened the reliability of its power production and distribution, and helped it meet the increased electricity demand. In 2022, CKPower had a total installed capacity of 11,704,379.09 MWh.
Furthermore, CKPower has put in place production and distribution control systems with maximum reliability. The Company’s power plants are not only designed by experts and equipped with measuring tools of international standards but are also subject to regular inspection by specialists and maintenance according to detailed schedules throughout their life span.

OPTIMIZATION AND LOSS PREVENTION IN PRODUCTION
In 2022, the system availability was at 90%. There were a total of 1-2 unplanned outages in Nam Ngum 2 Power Plant and Bangpa-in Cogeneration Power Plant. To ensure the availability of its power plants for continuous operations with maximum efficiency and manage the readiness of its power plants, machinery, and equipment, CKPower formulates annual preventive maintenance plans, which ensure that equipment and machinery are inspected as scheduled and that maintenance is carried out as planned, and prepares suitable and adequate amounts of critical equipment, supplies, and spare parts for power plant maintenance. In addition, CKPower also operations in accordance with the ISO 9001:2015 standard.
In 2022, CKPower implemented initiatives to enhance efficiency and prevent losses in production, including machinery optimization, energy consumption reduction, and reduction of loss in production.
CRISIS MANAGEMENT
To ensure smooth operations as well as the reliability and availability of the power production and distribution systems, CKPower has announced a business continuity management policy for the Company and its subsidiaries as well as issued emergency manuals and conducts emergency drills every year to prepare against unforeseen incidents, such as fires and floods, as well as climate change risks. CKPower also analyzes and assesses risks from climate change on a year basis as it can have direct impact on the Company’s operations, and once the climate change risks have been identified, mitigation plans are formulated in response to such risks. In addition, CKPower regularly renovates its power plants to improve resistance to extreme heat or cold and flood-proof the utility systems, with a team of engineers and experts assigned to proactively monitor safety through installed sensors and real-time monitoring systems.
