EGCO Group manages air quality in accordance with its operational excellence standards by setting stack emission standards for its power plants, which are more stringent than required by law and Environmental Impact Assessment (EIA) reports. EGCO Group also establishes quantitative targets for continuous emission reduction and integrates these criteria as Key Performance Indicators (KPIs) at the plant level to ensure ongoing control, monitoring, and operational improvement.

This approach enables EGCO Group to maintain air quality performance above regulatory standards, effectively reducing environmental risks and adverse environmental impacts. This strengthens long-term stakeholder confidence.
Furthermore, EGCO Group conducts regular air quality monitoring through continuous stack emission measurement using a Continuous Emission Monitoring System (CEMS), complemented by periodic measurements conducted every six months by government-authorized third-party inspectors. Monitoring data is reported on a continuous basis to the Department of Industrial Works and disclosed via display screens at plant premises, ensuring full regulatory compliance.
EGCO Group is dedicated to continuously improving and optimizing its operations. Emphasis has been placed on inspection, maintenance, and repair of machinery and related equipment. Moreover, EGCO Group 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 conveyor 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.
