Hydro Power Plants

Hydro-electric power plants utilize the natural process of the water cycle.

Environmental Management Systems in HPPs cover the following activities of power generation – basic components: 

  • Dam (a construction that blocks, redirects or slows the natural flow of water). Usually, dam construction involves water storage, reservoirs or even artificial lakes
  • Reservoir(artificial lake which supplies the steam turbines with the water stored)
  • Spillway. Spillways are necessary for dam safety and ensure the discharge of floodwater 
  • Power intake–This term describes the entry of water in the headrace tunnel
  • Headrace tunnel–Surge tower. The headrace tunnel carries water under pressure from the power intake to the surge tower
  • Hydro Power Plant. Here, water energy is converted into electric power (hydro-turbines, power generator, transformers)


The procedure of identifying environmental aspects (environmental risks) associated with the operation of HPPs considers the following: 

  • Discards in water
  • Discards in soil
  • Noise
  • Use of ancillary materials and natural resources
  • Use of energy
  • Generated Waste and By-products
