Hydroelectric power plant

  1. 1. Istituto di Istruzione Superiore “B. Pinchetti” Hydroelectric power plant Visit to the hydroelectric power plant of Grosio.
  2. 2. Istituto di Istruzione Superiore “B. Pinchetti” Water cycle and Energy Sun Gravitational Energy Energy
  3. 3. Istituto di Istruzione Superiore “B. Pinchetti” Water Wheels
  4. 4. Istituto di Istruzione Superiore “B. Pinchetti” From Hydropower to Electric Power Electrical Electricity Potential Energy Energy Kinetic Energy Mechanical Energy
  5. 5. Istituto di Istruzione Superiore “B. Pinchetti” Power factors The power of the plant depends on: the volume of water which runs within the time unit ((m3/s). the difference of altitude between the intake point and the outlet point
  6. 6. Istituto di Istruzione Superiore “B. Pinchetti” Pumped storage system During the night, water is Water is released back to the pumped from the lower lower reservoir to generate reservoir to the higher one. electricity during peak of the demand .
  7. 7. Istituto di Istruzione Superiore “B. Pinchetti” For us a history of a lot of years
  8. 8. Istituto di Istruzione Superiore “B. Pinchetti” Grosio plant
  9. 9. Istituto di Istruzione Superiore “B. Pinchetti” Hydroelectric Installation
  10. 10. Istituto di Istruzione Superiore “B. Pinchetti” The penstock
  11. 11. Istituto di Istruzione Superiore “B. Pinchetti” Plants and penstocks everywhere
  12. 12. Istituto di Istruzione Superiore “B. Pinchetti” No fuel expense
  13. 13. Istituto di Istruzione Superiore “B. Pinchetti” Hydropower – Pros Operational emissions-free with no CO2, NOX, SOX, hydrocarbons, or particulates Renewable resource with high conversion efficiency to electricity (80+%) Dispatchable with storage capacity Usable for base load, peaking and pumped storage applications Scalable from 10 KW to 20,000 MW Low operating and maintenance costs Flood control
  14. 14. Istituto di Istruzione Superiore “B. Pinchetti” Impacts of Hydroelectric Dams
  15. 15. Istituto di Istruzione Superiore “B. Pinchetti” Hydropower – Cons Impacts on aquatic ecology, including fish migration and water quality. River flows and natural flooding cycles sedimentation/silting are changed. Variable flow in the river, with danger for fishers and people staying in bed river. Sediments are deposed at the bottom of the reservoir. Loss of land under the reservoir.
