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

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 .

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

Impacts of Hydroelectric Dams

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.
