EVNNPC's power losses fall to the lowest level ever recorded

Reducing power losses is one of the key tasks assigned to EVN's member units to improve production and business efficiency, reduce costs, make more efficient use of energy resources, and contribute to environmental protection. This task has been emphasized by the Prime Minister in Directive No. 10/CT-TTg dated 30 March 2026 on strengthening electricity conservation and developing rooftop solar power.

In recent years, EVNNPC has achieved significant results in reducing power losses. Over the past five years, the Corporation's power loss rate declined from 4.54% in 2021 to 3.54% in 2025, the lowest level ever recorded. Overall, during the five-year period, EVNNPC reduced its power loss rate by 1 percentage point, continuing to maintain a sustainable downward trend.

Applying digital technology for proactive management

A clear understanding of these challenges has enabled EVNNPC to develop appropriate solutions for effectively achieving its power loss reduction objectives. Among these, improving the quality of power grid operation and management in conjunction with the application of digital technologies has been identified as one of the key solutions.

This approach enables the automatic collection of electricity consumption data with a high degree of accuracy, significantly reduces manual operations, and supports the monitoring of electricity output almost in real time. Through this system, operating units can quickly detect abnormalities in electricity output, load demand, remote metering connectivity, or metering data discrepancies, allowing timely corrective actions to be taken and thereby contributing to the control and reduction of power losses.

In addition, EVNNPC is making effective use of its technical management systems and power grid operation databases, which allow power losses to be monitored down to each transmission line, substation, and management area. Data analysis on digital platforms enables the Corporation's units to accurately identify the causes of power losses, thereby implementing appropriate technical and management solutions to improve the efficiency of system operation and management.

EVNNPC employees use advanced technological equipment to inspect and monitor power grid operations.

In addition, modern technologies such as thermal imaging cameras, partial discharge measuring devices, and equipment for monitoring operating conditions are being widely deployed to detect defects in the power grid at an early stage, including overheating contact points, phase imbalance, and localized overloading. As a result, many potential causes of power losses can be addressed promptly, thereby enhancing the reliability of the electricity supply.

By accelerating the application of digital technologies and advanced monitoring solutions, EVNNPC has transformed its power loss management from a traditional approach to a more proactive, accurate, and efficient management model. This also provides an important foundation for the Corporation to continue developing a smart grid, improving the quality of electricity supply, and enhancing the operational efficiency of the power system.

At the same time, EVNNPC continues to strengthen inspection, supervision, and oversight of its member units to ensure the synchronized implementation of technical and management solutions aimed at improving the operational efficiency of the power system and ensuring a safe and stable electricity supply for customers.

To further achieve the power loss reduction targets set out in the Prime Minister's Directive No. 10, in addition to the efforts of its employees, EVNNPC has proposed that the competent authorities continue to allocate adequate resources and improve relevant mechanisms and policies to support investment in, renovation, and upgrading of the power grid, particularly in mountainous, remote, and isolated areas, as well as in regions experiencing rapid load growth. These measures are considered essential to enhancing the operational capability of the power system, reducing power losses, and improving the quality of electricity supply.

The Corporation also hopes that local authorities will continue to cooperate in land clearance activities and the protection of power transmission safety corridors, while working together to strengthen public awareness campaigns promoting economical and efficient electricity use.
