Micro-hydro technology, also known as micro-hydropower, is a renewable
energy technology that harnesses the power of flowing water to generate electricity on a small
scale. It serves as a clean and renewable energy source, ideally suited for powering remote
communities, rural areas, or individual homes, especially in areas where establishing a
reliable grid connection is logistically challenging.

Micro-hydro systems can vary in size, with some capable of generating just a
few kilowatts of power, suitable for a single household, while others can generate several
hundred kilowatts, providing electricity for a small community. Notably, micro-hydro
technology offers reliability, as water flow tends to be more consistent compared to energy
sources like wind or solar power, and its potential to provide clean, sustainable energy without
producing significant greenhouse gas emissions.

Establishing a Micro-Hydro project necessitates several key components, including access to
a natural water source, an intake structure, a penstock pipe, a turbine, a generator, and
transmission cables. However, the viability of micro-hydro technology depends on factors
such as the availability of a suitable water source with continuous flow, the environmental impact on local
ecosystems, and the economic feasibility of building and maintaining the infrastructure.
Successful implementation of micro-hydro projects hinges on meticulous design, thorough
evaluation of environmental impacts, and active engagement with the local community. Seasonal water flow may be an issue/

For Example - An exemplar of micro-hydro application is observed at the Bluff Eco-Park in
Durban, South Africa. Here, a micro-hydro system is employed to generate electricity for the
park's operations, concurrently reducing their dependence on the conventional grid.
