Hydropower
The use of flowing water to produce electrical energy.
Hydroelectric Dam
A structure that blocks the flow of river water to create a reservoir or raise water level for energy generation purposes.
Turbine
A device that converts the kinetic energy of water into mechanical energy.
Generator
A machine that converts mechanical energy into electrical energy.
Head
The vertical distance between the water source and the turbine, which determines the potential energy available for hydropower generation.
Flow Rate
The volume of water passing a point in a given period of time, it is crucial for determining hydropower potential.
Penstock
A pipe or conduit that carries water from the reservoir to the turbines in a hydropower plant.
Run-of-River Hydropower
A type of hydropower generation that utilizes the natural flow of a river without a large reservoir.
Pumped Storage
A form of hydropower that stores energy by pumping water uphill to a reservoir during periods of low demand and releasing it during high demand.
Impulse Turbine
A type of water turbine where jets of water hit the turbine blades creating motion.
Reaction Turbine
A water turbine that operates with both the water's pressure and velocity to create motion.
Rated Capacity
The maximum electrical output a hydropower plant can produce under specific conditions.
Capacity Factor
The ratio of the actual output of a power plant to its potential output if it could operate at full-rated capacity continuously.
Hydraulic Efficiency
The efficiency at which a hydropower plant converts the energy of water into mechanical energy.
Fish Ladder
A structure that allows migratory fish to pass around barriers like dams.
Environmental Flow
The water flow regimes provided within a river, wetland, or coastal zone to maintain ecosystems and their benefits.
Renewable Energy Certificate (REC)
A market-based instrument that represents the property rights to the environmental, social, and other non-power attributes of renewable electricity generation.
Water Footprint
The total volume of fresh water used to produce the goods and services consumed by an individual or community.
Siltation
The accumulation of sediments in reservoirs, which can reduce the capacity and efficiency of hydropower plants.
Gross Head
The total height difference between the water intake and the tailrace where the water reenters the watercourse.
