About NHPC Limited:

NHPC Limited (erstwhile National Hydroelectric Power Corporation) is an Indian public sector hydropower company that was incorporated in 07.11.1975 to plan, promote and organise an integrated and efficient development of hydroelectric power. 

Recently it has expanded to include other sources of energy like solar, geothermal, tidal, and wind. 

At present, NHPC is a Navaratna enterprise of the Government of India and among the top ten companies in the country in terms of investment base. 

Baira Suil Power Station in Salooni tehsil of Chamba district was the first project undertaken by NHPC.

From integrating power with growth to empowering a greener tomorrow, the NHPC continues to illuminate India’s path toward a sustainable and energy-secure future. 

This year, NHPC celebrates its Golden Jubilee, remembering its remarkable journey of resilience, innovation and service to the nation of India. 

The 50th anniversary is also a tribute to the visionaries, engineers and dedicated workforce whose relentless efforts have transformed NHPC into a trusted name in India’s power sector.

Over the past five decades, NHPC has executed landmark hydropower projects in some of the most challenging terrains, while also diversifying into solar, wind and green hydrogen, reinforcing its status as a 100% Green Energy Company. 

NHPC has also played a pivotal role in harnessing the immense hydro potential of India’s rivers, lighting millions of homes and driving socio-economic progress in remote and mountainous regions. 

With an installed capacity of over 8,332 MW from 30 power stations and an additional 14 projects of over 9700 MW combined capacity under construction, NHPC continues to play a vital role in strengthening India’s energy security and advancing the nation’s transition towards clean and green power.

Beyond power generation, NHPC has remained committed to environmental conservation, community development and nation-building through sustainable practices and corporate social responsibility initiatives. Its projects have become landmarks of engineering excellence and environmental stewardship.
