Classification of Hydroelectric Powerhouses

1. Big Scale Hydroelectric Systems
Power of big scale system is 50 MW and over. 50 MW can light or is equal to 500.000 unit of 100 watt electric bulbs. In other words, if we assume that 5Kw electrical power required for a house, big scale powerhouses can meet the need of 10.000 houses. Electricity produced can be distributed with the energy lines to the other regions of the country.

2. Small Scale Hydroelectric Systems 
 Hydroelectric system which produces electricity between 10 to 50 MW is defined as small scale hydroelectric system. It can both connected to national grid system and use to power a town or large factories. We can say that 10 MW power is enough for a town with a population of 10000 citizens.

3. Mini Scale Hydroelectric Systems 
Hydroelectric systems which has power between 101 Kw to 10,000 Kw are called mini scale hydroelectric systems. These systems contributes to the national grid systems less then those explained above. These are usually designed and build for small settlements near a river. A 100 Kw hydroelectric turbine can supply energy needs of 20 houses.

4. Micro Scale Hydroelectric Systems 
These are the smallest hydroelectric systems and do not contribute to the national grid system. These are convenient for settlements which is located far from the main settlement areas. Their power usually just enough to power a home or a farm.
