Why is the construction of mini and micro hydroelectric power station on the rivers?
Mini and Micro hydro-power plant: A hydro-power plant that generates power up to 100 kW is a mini-hydro-power plant. Micro hydro-power plants are those which have a power generation capacity of less than 100 kW.
The explanation: The micro or mini-hydropower plants are generally located at river streams as the water head is insufficient to produce power of more than 100 kW. In contrast, hydro-power plants are made on large rivers or lakes where water heads can be sufficient to generate significant power.
