In response to increasing criticism over unannounced power cuts across Nepal, the Nepal Electricity Authority (NEA) has accelerated efforts to strengthen the country’s electricity transmission infrastructure. The state-owned utility is currently prioritizing the construction of several high-capacity 400 kV transmission lines as part of its broader strategy to ensure reliable power distribution and minimize load shedding.
Over the past few months, various regions in Nepal have experienced frequent and unannounced power outages. The NEA has attributed these disruptions to system tripping caused by outdated or inadequate infrastructure, particularly within the high-voltage transmission network. To address these issues, the authority has not only mobilized resources but has also issued public notices inviting expressions of interest from contractors for the installation of transmission lines in critical segments of the national grid.
Key Transmission Line Projects Under Construction:
- New Khimti–Dhalkebar Line
- Length: 80 kilometers
- Capacity: 400 kV
- Purpose: To reinforce east-west power flow and reduce congestion in central transmission corridors.
- Tingla–Dudhkoshi–Dhalkebar Electricity Highway
- Length: 118 kilometers
- Capacity: 400 kV
- Purpose: To serve as a major electricity highway supporting upcoming hydropower projects in eastern Nepal.
- Arun (Hub)–Inaruwa Segment
- Length: 94 kilometers
- Capacity: 400 kV
- Purpose: To transmit power generated from the Arun River basin’s hydropower projects to the national grid.
- Lapsifedi–Teenpiple Segment
- Length: 30 kilometers
- Capacity: 220 kV
- Purpose: To stabilize power supply in the Kathmandu Valley and surrounding areas.
Estimated Project Cost
The combined cost for constructing these transmission lines is estimated at USD 320 million. These investments are seen as critical to accommodating Nepal’s growing electricity demand and integrating newly developed hydropower into the national system.
The NEA has stated that timely completion of these projects will not only reduce tripping-related outages but also ensure stable, efficient, and nationwide electricity distribution—an essential prerequisite for supporting industrial development and everyday consumer needs.
As Nepal’s power generation capacity increases through new hydropower projects, enhancing transmission infrastructure remains key to ensuring energy security and reliability across the country.
