Management Approach​

Considering the diverse nature of our operations, the Company implements differentiated energy conservation approaches tailored to the specific characteristics of each business segment. These approaches aim to optimize energy performance, strengthen operational reliability, and support long-term energy security, while aligning with the Company’s broader sustainability and climate objectives.

For open-pit mining activities, energy efficiency initiatives focus on reducing fuel intensity in material handling and transportation by expanding the use of conveyor systems, refining haulage route design, and gradually electrifying vehicle fleets. Underground mining operations emphasize the efficient use of electricity through advanced automation, optimized control of ventilation and equipment systems, and systematic maintenance programs to sustain high operating efficiency. Within the renewable energy and solar rooftop businesses, energy use associated with operations and maintenance is minimized through improved logistics planning and streamlined maintenance schedules. At Combined Heat and Power (CHP) plants, overall energy utilization is enhanced by maximizing the benefits of co-generation and increasing the adoption of alternative fuels. Meanwhile, Combined Cycle Gas Turbine (CCGT) plants contribute to efficient and reliable power supply by offering high-efficiency generation with operational flexibility to respond to fluctuations in electricity demand.

To track performance, the Company monitors total energy consumption intensity as a key indicator of operational efficiency. In mining business, total energy consumption intensity was 0.473 GJ/tonne coal, which remained above the target threshold. This result reflects ongoing operational challenges and highlights areas for further efficiency improvement. In contrast, the thermal power business achieved a total energy consumption intensity of 2.56 GJ/MWh, successfully meeting the target. This performance demonstrates effective energy management and optimization of power generation processes. Overall, the results underscore the Company’s continued focus on improving energy efficiency, with targeted actions to enhance performance across all business segments.
