The construction of the substation and transmission line for supplying electricity generated from the projects located in the Marsyangdi watershed area to Kathmandu has been completed and brought into operation.

The construction of the 220/132 kV substation based at Markee Chowk, Aanbukhaireni Rural Municipality in Tanahun has been completed.

This substation is based on gas-insulated system (GIS) technology.

The substation built under the Marsyangdi-Kathmandu 220 kV transmission line project was charged and brought into operation on Tuesday.

Nepal Electricity Authority (NEA) has said with the charging of the substation, the 82-koilometre-long Marsyangdi-Kathmandu Transmission Line has become operational in 220 kV capacity.

NEA Managing Director Kul Man Ghising said that the infrastructure required to supply power produced from hydropower projects in Marsyangdi River corridor via the 220 kV transmission line has been readied with the operation of the substation at Markee Chowk.

He said the ‘voltage’ of the country’s integrated electricity system would be improved through this, ensuring adequate, reliable and quality power supply.

The NEA Managing Director added that electricity from the Marsyangdi corridor can be supplied towards Bharatpur also once the under-construction Markee Chowk –Bharatpur section of the Marsyangdi Corridor Transmission Line Project is completed.

Works are being carried out with the objective of completing this section of the transmission line within mid-June of 2025.

The construction of Matatirtha substation has been completed and it has come into operation since May.

Two power transformers each with the capacity of 160 MVA have been installed at both substations. Both substations are of 320 MVA capacity each.

The Marsyangdi-Kathmandu transmission line project had been initiated with the investment of the Government of Nepal and NEA, and with the grant support of the Norwegian government and the concessional loan from the Asian Development Bank.
