Introduction

Hydro Power, generated from the natural flow of water, is one of the most reliable and mature renewable energy sources in the world. Amid India’s rapidly evolving energy landscape, it plays a pivotal role in ensuring grid stability, energy security, and system resilience. Unlike intermittent sources such as solar and wind, hydro power provides firm, round-the-clock (RTC) electricity, along with the operational flexibility. As the country accelerates its transition towards a cleaner energy mix, Hydro Power remains indispensable.

Recognising this strategic importance, the Union Cabinet has approved the Small Hydro Power (SHP) Development Scheme that will support small hydro projects (between 1-25 MW capacity) to come up in different states.  The scheme will especially benefit hilly and North Eastern states with high potential for such projects. The approval is for the period FY 2026–27 to FY 2030–31, with a total outlay of ₹2,584.60 crore. The scheme aims to unlock approximately 1,500 MW of new SHP capacity, with a strong focus on hilly regions and the North Eastern States rich in untapped small hydro potential and often constrained by energy access challenges. By promoting decentralised and locally generated power, the scheme seeks to deliver reliable electricity to remote and difficult-to-access regions while reducing dependence on conventional fuels.

Beyond energy generation, the initiative has the potential to catalyse inclusive growth. Small hydro projects, with their minimal ecological footprint, limited land requirements, and long operational life, offer a sustainable pathway for development. By fostering local investment, generating employment, and strengthening regional economies, the scheme is going to position small hydro as a cornerstone of India’s sustainable and self-reliant energy future.
