Section 01
Hydro Power Generation — Industry Overview
Hydropower generates electricity from the potential and kinetic energy of flowing or falling water. Water stored at height is released through a conveyance system, drives a hydraulic turbine, and the turbine drives a generator.
BARREL presents hydro as a complete water-to-energy infrastructure ecosystem — from identifying a river basin and assessing its hydrological potential to generating electricity and delivering it to the grid.
DRIVER 1
Flow Q
How much water passes the turbine (m³/s) — set by hydrology, the flow duration curve and storage.
DRIVER 2
Net head Hnet
The usable height of fall (m) — gross elevation difference less losses in the waterway.
DRIVER 3
Efficiency η
Turbine × generator × system efficiency — typically 85–92 % overall for modern large units.
Major hydropower categories

2.1How a hydropower plant works
- 1Water is collected in a reservoir or diverted from a river.
- 2Water enters through the intake structure.
- 3Trash racks and screens keep debris out of the conveyance system.
- 4Intake gates and valves control the flow.
- 5Water travels through tunnels, canals or penstocks.
- 6Water reaches the turbine under the designed hydraulic conditions.
- 7The hydraulic turbine rotates.
- 8The turbine shaft drives the generator.
- 9The generator produces electrical energy.
- 10Transformers raise the voltage for transmission.
- 11Electricity is evacuated through the switchyard and lines.
- 12Water leaves through the draft tube and tailrace to the river.
2.2Basic hydropower engineering formula
Theoretical power
P = ρ · g · Q · Hnet · η
Preliminary estimate
P (kW) ≈ 9.81 × Q × Hnet × η
Net head is the gross elevation difference less hydraulic losses in the conveyance system. Final capacity accounts for seasonal flow, operating head, turbine and generator efficiency, auxiliary consumption and design constraints.
| Symbol | Description |
|---|---|
| P | Electrical output power (W) |
| ρ | Water density (kg/m³) |
| g | Acceleration due to gravity (m/s²) |
| Q | Turbine discharge (m³/s) |
| Hnet | Net hydraulic head (m) |

Pumped Storage Hydropower (PSH) — Strategic Energy Storage Vertical
One of the most important technologies for large-scale electricity storage and grid flexibility. Two reservoirs at different elevations: surplus electricity pumps water up; at high demand the water is released through turbines.
It works as a large-scale storage system and consumes more electricity in pumping than it returns in generation.
