The 120 MW Lower Kopili Hydroelectric Project in Assam’s Dima Hasao district was virtually inaugurated on 13 March 2026. Built at a cost of over Rs 2,300 crore, the project is expected to strengthen electricity generation, improve grid stability, and support sustainable development in the Northeast. The commissioning marks a major step in expanding clean energy capacity in the region.
Project Overview
The project is located in Longku in Dima Hasao, a hill district with hydropower potential. It has been developed as a run-of-the-river hydroelectric scheme. Such projects use flowing water to generate electricity with lower carbon emissions than thermal power plants. The Lower Kopili project adds 120 MW to Assam’s power infrastructure.
Strategic Importance
The project is expected to:
- Improve power availability in Assam and the wider Northeast.
- Support grid balance and reduce dependence on conventional energy sources.
- Promote renewable energy generation in a geographically sensitive region.
- Encourage long-term infrastructure development in Dima Hasao.
Economic and Local Impact
Local authorities and residents see the project as a catalyst for growth. It is likely to create opportunities in employment, transport, and allied services. Better electricity access can also support small industries, public services, and household welfare. For a district like Dima Hasao, reliable power supply is closely linked with broader socio-economic progress.
Background and Commissioning
The foundation stone for the project was laid on 7 October 2021. Its completion reflects the long gestation period often associated with large hydropower projects in hilly terrain. The successful commissioning is being viewed as an important milestone in Assam’s energy and development agenda.
