Low-pressure micro hydropower plants offer a sustainable solution for decentralized energy generation in regions with low-head water resources. This study explores the design, performance, and feasibility of low-pressure micro hydropower systems, focusing on their efficiency, environmental impact, and economic viability. Using a combination of theoretical modeling and field data from operational plants, the research evaluates turbine technologies, such as Kaplan and cross-flow turbines, optimized for low-pressure conditions (head < 5 meters). Results indicate that these systems achieve efficiencies of 70-85% under optimal conditions, with minimal ecological disruption compared to conventional hydropower. Economic analysis suggests cost-effectiveness for rural electrification, with payback periods of 5-10 years. The study highlights the potential of low-pressure micro hydropower as a scalable renewable energy solution, particularly for off-grid communities, while identifying challenges related to site-specific design and maintenance. This work underscores the need for further research into modular turbine designs to enhance accessibility and performance.
