2020 Performance
All power plants emphasize the most efficient utilization of fuels, energy and raw water which are the most important raw materials of electricity generation, for cost benefits as well as the benefits to the environment and community.
1.1 Fuel consumption and heat utilization
The following is fuel consumption and gross electric output of RATCH-controlled power plants - Ratchaburi Power Plant, Tri Energy Power Plant, Nava Nakorn Electricity Power Plant, Berkprai Cogeneration Power Plant and RATCH Cogeneration Power Plant in Thailand as well as Kemerton Power Station and Townsville Power Station in Australia:

1.2 Water consumption
Power plants in Ratchaburi Province use raw water primarily from Mae Klong River, a major river in the province that receives water from Vajiralongkorn Dam, Tha Thung Na Dam and Mae Klong Dam. As the river chiefly supports irrigation and agriculture, RATCH Group’s power plants give importance to the dams’ water releases and raw water usage. The data is the basis for the assessment of risks relating to water shortage and conflicts with community over water as well as water stress accordingly to World Resources Institute (Aqueduct Water Risk Atlas and the Water Risk Filter). The monitoring showed there was no fight over water and no sign of shortage in the river, from upstream to downstream.
Although, the Chao Praya River as a raw water resource of tap water used in Nava Nakorn Cogeneration and RATCH Cogeneration power plants was designated as area of moderate to high water stress (2-3), there was no sign of water shortage affected to the generation and no fight over water with
