Environmental Stewardship

         EGAT has undertaken its mission in an environmentally responsible manner to ensure the sound environmental practices are in full compliance with all applicable laws and regulations. EGAT has continuously implemented environmental management systems according to the international standards, such as conducting Environmental Impact Assessment (EIA) reports in order to prevent and mitigate environmental and social impacts. The key environmental issues taken into consideration are as follows:

  • IEE for the project of submarine cable of 230 kV of Khanom - Samui Island

Greenhouse Gas Management

         EGAT gives importance to the activity to decrease the effect of the climate change by implementing EGAT long-term plan in greenhouse gas management (2018-2030) in response to Thailand’s policy on reducing greenhouse gas emissions and to support the Nationally Determined Contribution (NDC).

         For the implementation of the project of greenhouse gas reduction in 2020, EGAT received carbon credit of 110,266 tCO2e from Thailand Greenhouse Gas Management Organization (Public Organization) for EGAT’s Kiew Koh Ma Hydropower Plant which is a volunteer project under Thailand Voluntary Emission Reduction Program (T-VER). Moreover, Klong Tron Dam Hydropower Plant which was estimated to have greenhouse gas reduction of 6,425 tCO2e/y has also been registered to be under T-VER.

         Moreover, EGAT gives importance to corporate carbon footprint assessment and has prepared a report of greenhouse gas emissions of the organization in accordance with ISO 14064-1. The report covers the operating areas of EGAT reflecting transparency of the greenhouse gas emissions in its operation. In 2020, the amount of greenhouse gas emissions was 31.59 MtCO2e. The information on greenhouse gas emissions will be used in the management of greenhouse gas emissions with efficiency.

         In addition, EGAT organized the event “Thailand Clean Energy Network 2020” to announce the success of the allies of electricity producers comprising EGAT and IPPs in the reduction of greenhouse gas emissions of 10.03 MtCO2e which EGAT submitted to the Ministry of Energy as a part of the reduction of greenhouse gas emissions of the energy sector. In the event, the Renewable Energy Certificate (REC) business was launched, in which EGAT has been authorized by the International REC Standard Foundation (I-REC) to be the sole issuer of I-RECs in Thailand.

Environmental Quality Monitoring

         EGAT has a strong determination to adopt measures to prevent and control the environmental impacts which might occur as a result of EGAT’s operation, in particular the organization’s emissions to the air such as sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2). Moreover, EGAT continuously monitors the noise level, water quality, water ecosystem, quality of life, as well as garbage and waste management. Discharges to the water have been managed in compliance with all applicable environmental laws including the improvement of the overall environmental quality.

Sustainable Resource Use

         EGAT continues to pursue clean and green energy sources by promoting the development and consumption of renewable and alternative energy, ranging from hydropower, wind, solar, geothermal, and biomass. In 2020, a total of 13,242.23 million kWh of electricity from clean energy sources was produced from EGAT’s power generation system.
