Attending the symposium was Member of EVN’s Board of Directors Dang Huy Cuong. The symposium took place in a hybrid format in Hanoi, connected online to all the power generation units in the Group.
The goal is to ensure availability and reduce incidents of generating units
Reporting at the symposium, Director of EVN’s Operation and Technical Department Le Viet Hung presented information about the technical management of the power generation sector. In which, he stated that strengthening reliability-centered maintenance (RCM) at power plants will directly contribute to improving the availability and responsiveness of generating units, ensuring the 2024 power generation target.
The total installed capacity of Vietnam's power system in 2023 reaches more than 84,000MW, an increase of about 4.5% compared to 2022. The capacity scale of the power system currently ranks first in Southeast Asia. In terms of ownership structure, private investors account for 42.49% of the total installed capacity; BOT power plants account for 11.06%. EVN and its affiliated power generation corporations (GENCOs) own only 34.93% of the total system capacity. In that context, system operation to secure sufficient electricity for socio-economic development poses a big challenge.
In 2024, EVN's power plants are focusing all efforts and devoting all resources to electricity supply; Achieving and exceeding technical management targets. Power plants must ensure the availability and responsiveness of generating units; Strictly control heat loss and coal consumption; reduce incidents, being ready to generate electricity following dispatching orders, especially during the peak months of the 2024 dry season.
To achieve those important goals, specific solutions have been directed and assigned by EVN to each power generation unit. In particular, RCM maintenance is one of the key solutions.

Why RCM should be promoted?
RCM is a well-known advanced approach in the world with many advantages, helping to optimize maintenance costs and bring high flexibility; Enhance equipment reliability and performance, and prevent incidents. The RCM approach targets and prioritizes the maintenance of factors with the greatest impacts, helping to define priorities and assign resources effectively.
EVN’s member units have studied the RCM approach since 2017, piloted it since 2019, and widely applied it from 2021.
Hydropower plants have applied RCM to generating units. Thermal power plants have applied RCM to equipment systems in order of priority of importance and materiality. Notably, many thermal power plants under Power Generation Corporation 3 (EVNGENCO3) have completed RCM analysis for all equipment systems, 3 years ahead of the schedule.
EVNGENCO3 Power Plant Service Company implements RCM with good results.
Although the RCM application duration has not been long, it can be seen that the reliability of EVN's power plants has clearly improved in recent years.
At the symposium, units also raised many ideas to overcome outstanding problems and improve the quality of RCM work.
