Hydro Power Potential of North-East India

The northeastern region of India is known to have a vast potential for untapped hydropower. The region is blessed with several major rivers such as the Brahmaputra, the Barak, the Dibang, the Lohit, and the Subansiri, which have the potential to generate a significant amount of electricity.

According to estimates, the region has a potential hydropower generation capacity of around 60,000 MW, out of which only a small portion has been harnessed so far. The untapped potential is mainly due to the lack of infrastructure, funding, and technical know-how to develop these projects.

The government of India has been working on several hydropower projects in the region, such as the 2080 MW Dibang Multipurpose Project, the 2000 MW Lower Subansiri Hydroelectric Project and the 2000 MW Kameng Hydroelectric Project.

The development of hydropower projects in the region could bring significant economic benefits, including job creation, increased income for local communities, and improved access to electricity. It could also help to reduce the country’s dependence on fossil fuels, and promote sustainable development.

Garo Khasi Jaintia

Lets see about Garo Khasi Jaintia Hills of Meghalaya

  • Meghalaya, a small hilly state in North East India, came into existence as an autonomous state within the state of Assam on 2 April 1970 comprising the United Khasi and Jaintia Hills and the Garo Hills districts. 
  • But this experiment of creating an autonomous state within the mother state did not work for long due to the lack of cooperation between the two Governments. 
  • Consequently, the Government of India accorded full-fledged statehood to Meghalaya on 21 January 1972 to satisfy the persistent demand of the people.
  • The boundaries of the state are demarcated by the Goalpara and Kamrup districts of Assam in the north, the south-western part of the district of Goalpara and a part of Rangpur district of Bangladesh in the west, the Mymensingh and Sylhet districts of Bangladesh in the south and the north Cachar and Karbi Anglong districts of Assam in the east. 
  • The total geographical area of the State is approximately 22,429 sq. km and consists of primarily steep hills and deep gorges with very limited areas covering valleys and plains land.

Broadly, the state is divided into three regions in terms of its physical features:

  • The Central Plateau includes the Khasi – Jaintia Hills, which is an imposing, plateau with rolling grasslands, hills and river valleys. The Garo Hills forms the western part of the plateau. Its elevation varies between 150 M to 1961 M above the mean sea level. The highest point of the plateau and that of the entire state is the Shillong Peak whose elevation is about 196I M. It serves as a catchment area for rivers and streams traversing the state. Comparatively, it has the largest area of grassland, which can be profitably utilised for animal husbandry, dairying and horticulture. It is the main centre of potato cultivation and vegetables for supply outside the state. 
  • The border area begins where the southern face of the Central Plateau ends. Deep gorges and slopes at the foot of which a narrow strip of plain land runs along the international border with Bangladesh form the southern region of the state. It is a region with the heaviest rainfall. The world-renowned Cherrapunji and Mawsynram, the wettest places in the world are located in this area. The areca nut plantations and subtropical and tropical fruits like mandarin, lemon, guava, pineapple and banana are grown in plenty in this region. 
  • Like the border area, the submontane region also forms a continuation of the Central Plateau till it merges with the plains of Assam. But unlike the border area, which is generally steep and abrupt in certain places, it slopes gently down until it merges with the plains of Assam in the north. It is a region of comparatively lower rainfall but has favourable scope both for agriculture and horticulture. 
  • To summarise:
    • Garo Hills: Nokrek Peak is the highest peak here.
    • Khasi Hills: got its name Khasi tribes, Shillong is the highest peak.
    • Jaintia Hills: located to the east of the Khasi Hills.
