Assessing reduction of GHG from power generation under TGO guidelines
RATCH assesses the reduction of GHG emitted by its power generation based on the energy-efficiency calculation methodology developed in 2019 by Thailand Greenhouse Gas Management Organization (TGO). Thailand has adopted two base years to measure the reduction in GHG emissions.

*NAMA = Nationally Appropriated Mitigation Action, referring to national actions to reduce global emissions. NDC = Nationally Determined Contribution, referring to efforts by each country to reduce national emissions.
The CO2 Intensity (CI) in 2010 (base year) is calculated from each type of fossil-fuel power plants of EGAT and IPPs, which 2010 baseline CI of natural gas is at 0.4945 tCO2e. Based on the natural gas baseline CI, CO2 Intensity of Ratchaburi Power Plant in 2020 is as follows:
Note : 1) Calculation is based on the power plants’ 2020 data on natural gas consumption.
2) Tri Energy Power Plant was reserved shutdown until PPA’s expiration on 30 June 2020.
Ratchaburi Power Plant’s set target of GHG emissions per net megawatt-hour based on EGAT’s 2010 CI baseline of natural gas at 0.4945 tCO2e. In 2020, the power plant uncompleted the target; its GHG emission per electric power unit was higher than base year of 2010.
Energy-saving and efficiency enhancement projects and activities in 2020
All individual power plants were dedicated in finding ways to continually enhance production efficiency and reduce energy consumption, as efficient fuel and energy consumption would help reduce GHG emitted by their operations.
