Hydropower is a crucial renewable energy source, harnessing the power of flowing water to generate electricity. Nepal, with its unique geographical features, is a prime location for hydropower development. The country's vast network of rivers and steep topography create ideal conditions for generating hydroelectric power. As Nepal faces growing energy demands, hydropower stands out as a sustainable solution, offering a clean and reliable source of energy.

Nepal’s Hydropower Potential

Nepal's geography and hydrology are perfectly suited for hydropower projects. The country is home to numerous rivers, including the Kosi, Gandaki, and Karnali, which originate from the Himalayas and flow through the country. These rivers provide a steady and abundant water supply, essential for hydropower generation.

Nepal's estimated hydroelectric potential is a staggering 83,000 MW. However, the actual utilization to date is significantly lower, highlighting the vast untapped potential. This discrepancy underscores the need for more investment and development in the hydropower sector to fully leverage Nepal's natural resources.

Problems in the economy of Nepal:

Declining foreign exchange :

The foreign exchange reserves (forex) of the country are decreasing. The Nepal Rastra Bank (NRB) noted that forex reserves were less than $2 billion USD compared to mid-April last year. As a result, the country can hold imports only for another six and a half months. Remittances are the main source of foreign exchange in Nepal, accounting for roughly half of total reserves, while import costs are the primary cause of the currency's decline. 

Trade deficit :

The high import rate and high dependence on other countries have always been seen in Nepal and have been a major problem. Exports have always been lower than imports. According to the economic survey for fiscal years 2020-2021, the export is $2.69 billion, while the import is $15.17 billion. From this, we can recognize how the country is highly dependent on other countries and is facing a trade deficit

Inflation :

When the money supply in the market increases and the production costs are high, this leads to inflation in the country. According to the Nepal Rastra Bank (NRB), the current inflation rate in Nepal is 7.28 percent. 

Despite these problems, many sectors have been contributing to the betterment of the economy of Nepal. New development plans and policies are being formulated. Likely, hydroelectricity is playing a great role in it. Since Nepal is the greatest source of water resources, if the government keeps hydroelectricity in mind and targets it for the economic growth of the country, it can be a suitable and best alternative for the country.

Nepal is rich in water resources. It has over 6,000 big rivers, hundreds of lakes, and many natural spring. In terms of eating resources, Nepal stands in the second position in the world. Nepal's  borders are situated at the confluence of two big rivers, Mechi in the east and Mahakali in the west. Most of the rivers in Nepal originate from mountains. Hence, hydroelectricity can be easily produced through those rivers. The potential of hydroelectricity in Nepal is about 83,400 MW, which is about 2.27% of the total potential of the world.

The potentialities of hydroelectricity production in Nepal in different basins are presented below:

Hydro Power Potential in Nepal

The above figure clearly shows that the Karnali and Mahakali river basins occupy the first and second positions in hydroelectricity production capacity. The second position is occupied by the Koshi, the third by the Gandaki, and the southern rivers, respectively.

The first hydroelectricity project was constructed in 1968 BS with the installation of a 500 KW capacity. According to the economic survey 2020/21, total hydroelectricity production is 1842 MW, which is merely 2.22% of total potential.
