Note : Tri Energy Power Plant was ordered reserved shutdown in January–June and its power purchase agreement expired on 30 June 2020. • Recycle water by treating water with the Reversed Osmosis (RO) and Ultra Filter systems,
improving the quality of treated water and reusing the water in the production process.

3. Power plants’ energy saving
RATCH Group’s power plants have put in place the energy efficiency and conservation plan, aimed at reducing energy consumption and raising renewable energy. For instance, during a reserved shutdown, Ratchaburi Thermal Power Plant was powered by solar panels floating on its reservoir, which reduced production cost, fuel consumption and Scope 2 GHG emissions. Additional information on energy-saving approaches appeared in GHG Management and Adaptation to Climate Change Section: Page 45
4. Power plants’ environmental management
RATCH intends to deliver good environmental management that concerns the quality of air, water, noise, waste and the ecosystem of power plants in accordance with laws and international standards, to earn public recognition. Its power plants thus put in place the environmental management system that covers preventive and elimination measures as well as continuous monitoring on environmental quality within power plants and in community. The environmental data, preventive measures and impact management approaches are reported to the Office of Natural Resources and Environment Policy and Planning every six months. In addition, the ISO14001 environmental standard was applied to enhance the management efficiency such as Ratchaburi Power Plant, the Company’s main asset.
In 2020, the power plants completely operated accordingly to environmental laws. They experienced no complaints or penalties relating to incompliance or violations.
