3. Project Highlights & Value
The “Installation of Short-Circuit Current Limiting Equipment” project was developed by EVNNPT, with NPTPMB acting on behalf of EVNNPT in project management and administration. Power Engineering Consulting Joint Stock Company 2 (PECC2) was responsible for the survey and preparation of the construction design, while Power Engineering Consulting Joint Stock Company 1 (PECC1) carried out the construction design review.
The project was implemented within the existing boundaries of the Hiep Hoa 500kV Substation in Dai Mao Village, Dai Thanh Commune, Hiep Hoa District, Bac Giang Province, as well as the Trang Bach 220kV Substation in Yen Tho Commune and Hoang Que Commune, Dong Trieu Town, Quang Ninh Province.
According to information from NPTPMB, upon completion, the project will contribute to meeting growing electricity demand in Northern Vietnam, strengthening regional grid interconnections, improving the reliability and safety of the transmission network, and reducing transmission losses. It will also support the safe and stable operation of Vietnam’s national power system.
As part of the project, PowerMore participated as the representative in Vietnam for Coil Innovation, Austria, and Condis, Switzerland. PowerMore coordinated the supply and provided installation guidance for 245kV current-limiting reactors and TRV capacitors at the Hiep Hoa 500kV Substation.
The equipment supplied with PowerMore’s involvement contributes to the safe, continuous, and stable operation of the transmission network, supporting socio-economic development while helping strengthen energy security and power system reliability.
