Air Quality

Why is this Important?

EGGO Group is dedicated to fostering sustainable environmental conservation and community well-being. Realizing the importance of air quality management around the power plants, the company is committed to minimizing the impacts on the environment and nearby communities.

EGCO Group focuses on controlling air emissions from its power plants to adhere to both local and international standards and relevant regulatory requirements. In addition, EGCO Group continually seeks to improve its air quality control system to enhance efficiency.

Management Approach

Emission Reduction Target & Performance

Long Term Target

Maintain the air quality of the power plants to be above the legal standards

2024 Target

  • NOx Emissions Intensity not over 7,994 Metric Tons per Gigawatt-hour

  • SOx Emissions Intensity not over 5,975 Metric Tons per Gigawatt-hour

2024 Performance

  • NOx Emissions Intensity not over 7,544 Metric Tons per Gigawatt-hour

  • SOx Emissions Intensity not over 5,969 Metric Tons per Gigawatt-hour

Emission Reduction Programs

To align with its operational excellence, EGCO Group has established stringent criteria for power plant stack emissions, which are one of the key performance indicators (KPIs) of the power plants. These criteria aim to control air quality at a level superior to legal standards and the requirements outlined in environmental impact assessment reports of the power plants. This is to ensure the efficiency of EGCO Group's operations while minimizing negative environmental impacts. Additionally, EGCO Group conducts regular air quality monitoring using continuous emission monitoring systems (CEMS) and periodic random inspections by external parties registered to the government every 6 months. Data are reported continuously to the Department of Industrial Works and displayed on the screens located in front of the power plants.

EGCO Group is dedicated to continuously improving and optimizing its operations. Emphasis has been placed on inspection, maintenance, and reparation of machinery and related equipment. Moreover, the company adopts modern and environmentally friendly equipment or technologies in its power generation processes. For instance, the installation of a nitrogen oxide (NOx) control system such as dry low NOx (DLN) and low-NOx burners (LNB) to reduce nitrogen oxide emissions resulting from fuel combustion, electrostatic precipitators (ESP), and flue gas desulfurization (FGD) and acid gas scrubbers to capture sulfur dioxide emissions generated during combustion processes.

Additionally, EGCO Group’s power plants have implemented measures to control dust from coal transportation. These measures include the use of an unloader with a vertical screw conveyer and a shielded conveyor to safeguard against coal spillage and dispersion. A water sprayer is also installed at the unloader hopper to prevent dust dispersion, adding an extra layer of protection.

EGCO Group is committed to continual development and improvement of its operations, striving for operational efficiency and achieving sustainable environmental goals.
