Small Hydro Turbines - Small hydro turbines support decentralized clean energy, ideal for remote and rural mini-grid electricity generation.

Small Hydro Turbines constitute the apparatus used in projects generally classified as having a capacity below a certain threshold, often defined as 10 megawatts. This category is crucial for decentralized power generation and rural electrification, especially in remote areas where large-scale grid connections are impractical or too expensive. The technology is characterized by a focus on simplicity, cost-effectiveness, and low environmental impact.

Small hydro utilizes a variety of turbine types—often including smaller Francis, Pelton, Turgo, and Crossflow designs—selected based on the specific head and flow conditions of streams, irrigation canals, or small rivers. The market for small hydro is experiencing growth driven by government incentives, the low-impact nature of run-of-the-river schemes, and the growing demand for off-grid or micro-grid solutions. Technological advancements include the use of standardized, modular components and simplified controls, reducing installation complexity and maintenance costs.

Small Hydro Turbines FAQs
What is the main advantage of small hydro turbines over large hydropower installations? The main advantage is their low environmental impact, lower initial capital cost, and suitability for decentralized power generation in remote communities.

Which non-traditional turbine design is often preferred for very low-head small hydro applications? The Archimedes Screw Turbine is increasingly used for very low-head and low-speed applications because it is robust, efficient, and highly fish-friendly.

What capacity is generally used as the upper limit for defining 'small hydro' projects? The upper limit is commonly defined as 10 megawatts (MW), with installations below 1 MW often categorized as mini or micro hydro.
