Energy Consumption

The Company focuses on maximizing the efficiency of natural resources and raw materials throughout the production process. We prioritize key resources essential to our business operations, such as fuel, electricity, and water, by analyzing and controlling Specific Resource Consumption. This approach ensures optimal value creation while consistently minimizing environmental impacts.

Utilization principle	Management of production process
Achieve optimal efficiency or least utilization.	Install better-than-required environmental quality control and monitoring systems, to prevent impacts on the environment, community and society. Improve production process to achieve efficient energy utilization. Monitor energy consumption. Assess the impacts of energy consumption; e.g., Scope 2 GHG emissions.
Utilize resources/raw materials efficiently and operate production process to minimize impacts on the environment and stakeholders.

Fuel Consumption for Power Generation

For the production of electric power and steam, 5 power plants in Thailand (with combined capacity of 3,288.41 MW) – Ratchaburi Combined Cycle, Hin Kong, RATCH Cogeneration, RATCH Energy Rayong, and RATCH Pathana Energy Power Plant – consumed 86,340 million megajoules of power from natural gas, diesel oil and electricity.
