1. Project Overview
- Project Name: Quang Trach 1 Thermal Power Plant Project
- Project Summary:
PowerMore, in collaboration with its European technology partner, supplied, installed, and integrated a 500kV Current-Limiting Reactor (CLR) system at the Quang Trach 1 Thermal Power Plant Substation. The solution was implemented to limit short-circuit currents within the extra-high-voltage transmission system, protect primary equipment, and improve the safety, stability, and reliability of the 500kV grid. - Industry / Sector: Thermal Power / Power Transmission / High-Voltage Equipment
- Project Type: Supply, installation, and integration of a 500kV Current-Limiting Reactor system
- Voltage Level: 500kV
- Location: Quang Trach 1 Thermal Power Plant Substation, Quang Binh Province, Vietnam
- Energization Milestone: 01:22 AM, April 29, 2025
- Technology Partner: Coil Innovation, Austria

2. PowerMore’s Scope of Work
For this project, PowerMore was responsible for the following key activities:
- Supplying the 500kV Current-Limiting Reactor solution.
- Coordinating with technology partner Coil Innovation for the equipment package.
- Installing the 500kV CLR system at the Quang Trach 1 Thermal Power Plant Substation.
- Integrating the equipment into the substation system.

3. Project Highlights & Value
The Quang Trach 1 Thermal Power Plant is being developed in Quang Binh Province and plays an important role in adding generation capacity to Vietnam’s power system. Once operational, the plant is expected to help meet growing electricity demand while contributing to greater power system stability and national energy security.
At 01:22 AM on April 29, 2025, this company successfully completed the energization of the 500kV GSUT#1 transformer bay and associated transmission lines during the back-energizing stage. This represented an important technical milestone, marking a key step toward bringing the power plant closer to its planned operational phase.
As part of the project, PowerMore supplied a 500kV Current-Limiting Reactor system in collaboration with Austrian technology partner Coil Innovation. The CLR system was installed and integrated into the Quang Trach 1 Thermal Power Plant Substation.


The 500kV CLR solution is designed to limit short-circuit currents within the extra-high-voltage transmission system. By reducing fault current levels, the equipment helps protect transformers and other primary substation equipment while improving the stability, operational safety, and reliability of the 500kV transmission network.
The Quang Trach 1 Thermal Power Plant Project is invested in by Vietnam Electricity (EVN) through Power Project Management Board No. 2. The project involves several specialized organizations, including PECC1, PTC2, and HDEC. This company is responsible for the coordinated supply and installation of primary equipment, transmission line structures, and the control and protection systems for the 500kV substation.
PowerMore’s participation in the supply, installation, and integration of the 500kV CLR solution for the Quang Trach 1 Thermal Power Plant Project further demonstrates its capabilities in delivering high-voltage power solutions for large-scale energy infrastructure projects.
The installation contributes to the safe and stable operation of the power system while supporting the technical requirements and reliability standards of Vietnam’s national transmission network.
