What are Small Hydropowers?
Small hydropower refers to the generation of electricity from flowing water on a smaller scale, usually defined as projects with a capacity of up to 50 megawatts (MW). Small hydropower systems harness the kinetic energy of water in rivers, streams, or existing water storage systems, converting it into usable electrical energy with minimal environmental impact. These systems are particularly beneficial in remote or rural areas where access to a national electricity grid may be limited or non-existent. They provide a reliable source of renewable energy, contributing to local energy needs while promoting sustainable development. The installation of small hydropower systems typically involves less civil construction work and utilizes existing structures such as dams or irrigation canals, which reduces costs and environmental disruption.
Increasing investments in renewable energy is propelling the small hydropower market growth. As per the data published by the International Energy Agency, USD 2 trillion was invested in renewable energy technologies and infrastructure in 2024. Increased funding drives governments and businesses to prioritize clean and sustainable energy sources such as on-shore and off-shore wind energy, solar energy, and small hydropower. Small hydropower, with its lower carbon footprint, offers a consistent and scalable option, making it attractive for rural electrification, industrial applications, and grid stability. The increased investment also reduces the capital barriers for small hydropower projects, making them more accessible. Furthermore, advancements in technology and infrastructure, fueled by increased investment, enhance the efficiency and feasibility of small hydropower, making them more appealing to energy planners.
