The book "Scheme of Small Hydro Power Plant" offers a comprehensive analysis of the use of energy from canal drops for electricity generation. It highlights the untapped potential of this energy source, which is present in many irrigation systems. The authors examine the different types of canal drops, particularly those with height differences of more than one meter and less than one meter. While the existing data only capture a small portion of the potential, it is demonstrated that there are numerous undiscovered sites throughout the region that could be developed for energy generation. With an estimated total capacity of over 800 MW from identified canal drops, the significance of this resource for future energy supply is emphasized. The book is aimed at professionals and enthusiasts in the field of renewable energy and provides valuable insights into the opportunities of small hydropower plants.
