The Matatirtha substation, Kathmandu Valley’s largest, and the Marsyangdi-Kathmandu 220 KV transmission line will be officially inaugurated today. Prime Minister Pushpa Kamal Dahal Prachanda will preside over the ceremony at Matatirtha, Chandragiri Municipality of Kathmandu at 3 pm.
The Matatirtha 220/132 KV substation, with a capacity of 320 MVA, will significantly improve power distribution from the Trishuli and Marsyangdi River hydropower projects. This development bolsters the reliability of Kathmandu Valley’s power grid.
The Marsyangdi-Kathmandu 220 KV double circuit transmission line stretches from the Markichoke substation in Tanahun to Kathmandu, enhancing the flow of electricity from Marsyangdi hydropower projects to the valley. Additionally, the Trishuli-Kathmandu 220 KV transmission line is complete and currently operates at 132 KV to bring power from the Trishuli River area.
Both the newly completed transmission lines connect at Badbhanjyang and feed into the Matatirtha substation. This allows an inflow of approximately 2,000 megawatts into the Kathmandu Valley. Power distribution to various areas, including Suchatar and Chobhar, will be managed through the substation. The 132 kV transmission line from Matatirtha will also support power transmission to Hetaunda.
This project was made possible through investments by the Nepal government, the Nepal Electricity Authority, grants from the Norwegian government, and subsidized loans from the Asian Development Bank. The total estimated project cost is 6 billion rupees.
