Power transmission line reached 6 and a half thousand circuit km

According to the data published by Nepal Electricity Authority By the financial year 2080/81, the length of 400, 220, 132 and 66 kV transmission lines has reached 6,507 circuit kilometers. Among the total transmission lines, the highest is 132 KV 4 thousand 136 circuit km and the lowest is 66 KV 514 circuit km .

400 kV transmission line is 644 circuit kilometers. In the financial year 2072/73, there were only 2 thousand 911 circuit kilometers of transmission lines. In the financial year 2073/74, 3 thousand 364, in the financial year 2074/75, 3 thousand 538, in 2075/76, 3 thousand 990 and in the financial year 2076/77 there were 4 thousand 269 circuit kilometers of transmission line. Similarly, in 2077/78 there were 4 thousand 874 circuit kilometers, 5 thousand 329 in 2078/79 and 5 thousand 742 circuit kilometers in 2079/80.

According to the authority, the capacity of the grid substation has reached 13,000 MVA. The grid substation capacity which was only 2223 MVA in the financial year 2072/73 has reached 13 thousand 50 by the last financial year. It has 400, 220, 132, 66 and 33 kV capacity substations.

The government and authorities have invested heavily in the construction of transmission lines and substations. The authority is investing in the transmission line by taking subsidized loans from its own sources and from development partner agencies. Executive Director of Nepal Electricity Authority Kulman Ghising said that a qualitative leap has been made in the construction of transmission lines during eight years.

'Local obstacles, land acquisition, forest area land use and tree felling approval process problems, geographically very risky and difficult areas where construction materials have to be transported by people, trucks and helicopters to work in the transmission line construction. Significant progress has been achieved', Executive Director Ghising said, 'During this period, many transmission lines of 400, 220 and 132 kV have been completed and put into operation. '

Ghising said that the construction process of the 400 kV transmission line from Butwal to West Attaria and the South Corridor transmission line passing through the major load centers of the country has been secured by various donor agencies.

He mentioned that major cities of the country have been divided into 11 clusters and a master plan of transmission and distribution structure that can supply the demand till 2050 has been prepared and implemented gradually.

The new Butwal-Gorakhpur 400 KV second international transmission line is under construction for electricity trade with India, which can transmit about 2,500 megawatts of electricity. On the other hand, eight years ago, the transmission line capacity for electricity import and export between Nepal and India was about 350 megawatts, but now it has reached about 2,000 megawatts.

Inaruwa-Purnia and Lamki-Bareli 400 KV transmission lines are under implementation . Also, the possibility of building more transmission lines between Nepal and India is being studied. To facilitate the electricity trade between Nepal, India and Bangladesh, the construction process of 400 KV transmission line from Inaruwa to Anaramani has been advanced .

In this way, it is ensured that the transmission line network that can export 20,000 MW of electricity by 2035 will be expanded. The Chilime-Kerung transmission line has also been advanced for electricity trade with the neighboring country China.

In order to make electricity supply reliable, quality and safe, a large investment has been mobilized towards distribution. Distribution line network of 33 and 11 KV and 400 volts has reached 2 lakh 9 thousand circuit kilometers to deliver electricity from grid substation to consumers.

By the financial year 2072/73, the distribution line was only 1 lakh 21 thousand circuit kilometers. At that time it was 58 percent electrification and now it has reached 99 percent . Among the total distribution lines, the maximum 400 volt distribution line is 150,000 circuit kilometers.

The capacity of the substation for distribution has reached 2,500 MVA. The number of distribution substations is 196. Eight years ago, the number of substations was only 80. The capacity was only 640 MVA .
