Small Hydroelectric Power Plants

Hydropower is the acquisition of water energy and its transformation into mechanical energy using water turbines, and then for electricity through hydrogenerators.

Currently, hydropower is mainly concerned with the use of waters with a high flow rate and a significant difference in levels. This is achieved by damming the upper water level.

The basic issue is to choose the right location for the hydroelectric plant. It is believed that in Europe and in Poland, most of the locations with preferential conditions for the construction of large hydropower plants, in which energy is stored in the form of accumulated water in retention reservoirs, has already been used.
Due to unfavorable conditions for large hydropower plants, the development of hydropower in Poland in the coming years will belong to the so-called Small hydroelectric power plants (MEW), which may use the potential of small rivers, agricultural retention reservoirs, irrigation systems, water supply systems, sewage systems and metastatic channels. These are power plants with installed capacity of not more than 5 MW.

  • they do not pollute the environment and can be installed in numerous places on small watercourses
  • are an element of the regulation of water relations
  • improve water quality through mechanical cleaning on the inlet grilles for floating turbines and increase water oxygenation, which improves its ability to self-purify biological
  • they are usually perfectly blended into the landscape
  • can be used for fire, agricultural, small agricultural processing, drainage, recreation, water sports and drinking water
  • can be designed and built within 1 – 2 years; equipment is widely available, and technology is mastered
  • technical simplicity causes high reliability, long life and low capital expenditure
  • can be controlled remotely
  • none
