Power Plant O&M services at Thermal Power Plants Above 1,200 MW: The Technical Challenge and PESE’s Capability

In the energy sector, operating a thermal power plant with a capacity exceeding 1,000 MW is not simply about generating electricity. It is a complex technical challenge that requires seamless coordination between equipment systems, operational procedures, operation and maintenance strategies, and a highly skilled technical workforce.

Every day, thousands of mechanical and electrical components, control and automation systems, and auxiliary facilities must operate continuously with high reliability and availability to ensure stable unit performance. Even a single failure within the system chain can affect the entire power generation process, potentially leading to unplanned downtime and significant operational costs for plant owners.

Therefore, for large-scale thermal power plants, Operation and Maintenance (O&M) goes far beyond troubleshooting when problems occur. It must be built on a foundation of professional technical management, preventive maintenance strategies, and comprehensive operational risk control.

PESE’s Operational Experience at Duyen Hai 2 Thermal Power Plant

At Duyen Hai 2 Thermal Power Plant, one of Vietnam’s large-scale coal-fired power projects with a total capacity of more than 1200 MW, PECC2 Engineering Services Company Limited (PESE) is currently providing Operation and Maintenance (O&M) services for the plant’s Balance of Plant (BOP) systems.

The systems operated and maintained by PESE include several critical components within the plant’s operational chain:

• Coal Handling System (CHS) - responsible for receiving, transporting, and supplying coal from the port area to the boiler bunker.
• Ash Handling System (AHS) - manages the collection, transportation, and treatment of ash generated from the coal combustion process.
• Water Treatment System (WTS) - provides treated water for plant operation, including service water and demineralized (Demin) water.
• Fire Fighting System (FFS) - esures fire prevention and firefighting safety across the entire power plant.

These systems are all large-scale and operate continuously under harsh conditions. Ensuring their stable, reliable, and safe operation requires strong technical capabilities, practical experience, and strict operational management processes.

When Engineering Expertise Becomes the Decisive Factor

Behind the stable operation of these auxiliary systems lies the continuous effort of PESE’s engineers and technical specialists.

On-site, PESE engineers carry out operational supervision, periodic equipment inspections, preventive maintenance activities, and troubleshooting tasks to ensure that all systems maintain a high level of operational readiness.

At the same time, technical procedures are standardized based on international technical standards and practical experience gained from large-scale power projects.

The combination of high-quality technical personnel, professional operating procedures, and effective maintenance strategies has enabled the plant’s BOP systems to maintain safe, stable, and reliable performance.

Strengthening PESE’s O&M Capability in the Energy Sector

The successful implementation of projects such as Duyen Hai 2 Thermal Power Plant continues to demonstrate PESE’s capability in delivering Operation and Maintenance services for large-scale energy and industrial projects.

Building upon the strong technical foundation inherited from PECC2, one of Vietnam’s leading energy consulting organizations, PESE is steadily expanding its O&M services across multiple types of energy projects, including:

• Thermal Power Plants
• Wind Power Projects
• Solar Power Plants
• Biomass Power Plants
• Industrial Energy System

Looking toward the future, PESE will continue investing in technical workforce development, advanced operation management systems, and innovative maintenance solutions to deliver high-quality engineering services, reliable operations, and sustainable economic value for clients.

With a stable workforce, strong professional expertise, and high professional standards, PESE is committed to partnering with project investors to ensure safe operations, optimized performance, and the sustainable development of energy projects.
