Power Generation Stability & Capability

Why is this Important?

Consistent electricity generation is critical for EGCO Group to maintain customer trust and ensure energy stability amidst growing demand. This drives the development of energy infrastructure for electricity generation and distribution. This supports the transition to cleaner and more efficient energy sources. Strengthening the electricity network presents both a challenge and an opportunity to advance energy technologies, ultimately improving quality and safety.

EGCO Group prioritizes investment in high-efficiency and low-emission energy sources to meet growing electricity demand, while enhancing project and operational efficiency. The company established strategies and commitments to maintain the stability of the country's electricity supply through setting plant availability targets and regular maintenance. It also focuses on investing in renewable energy and adopting modern technologies to ensure efficient electricity delivery in line with the Power Purchase Agreements (PPA).

Excellence Generation, Reliability and Availability

EGCO Group aims to enhance its electricity generation capacity to become a power producer excellence by seeking new efficient and environmentally friendly technology for its production process, for example, adopting technology solution TOMONI™ at Khanom Power Plant that enhances the efficiency and effectiveness of the power plant by increasing the temperature of exhausts from gas turbine, reducing energy consumption, and speeding up the response for any problem, thus increases machine reliability and avoids unplanned shutdown. In addition, EGCO Group has monitored the efficiency of machinery operation at each power plant constantly to maintain production efficiency of the plants and has set availability control value as a key performance indicator (KPI) of power plants which is also used for evaluating the performance of staffs at the power plants.

Sustainability Taxonomy Reporting

EGCO is not within the scope of taxonomy regulation, as Thailand Taxonomy Framework is not a mandatory regulation within Thailand . As such, compliance with this framework does not apply to our reporting obligations. Despite this, EGCO is committed to understanding and integrating relevant sustainability practices. We are actively studying the Thai taxonomy to evaluate its applicability to our operations. However, since a significant portion of our operations, including multiple power plants, located outside of Thailand, EGCO is currently evaluating the most effective methods to align our international reporting with relevant sustainability taxonomy standards.

Electricity Transmission and Distribution

EGCO Group has started commercial operations at the EGCO Cogeneration Replacement Power Plant in April 2024. With a total capacity of 74 MW, the plant has a Power Purchase Agreement (PPA) with the Electricity Generating Authority of Thailand (EGAT) to supply 28 MW to EGAT as the primary customer. The remaining electricity and steam produced will be sold to industrial customers in the Rayong Industrial Estate and nearby areas.
