How to Calculate Hydropower Output
Hydropower converts the potential energy of falling water into electricity.
Formula
Power (kW) = Flow Rate (m3/s) * Head (m) * 9.81 * Efficiency
Annual Energy = Power * 8,760 hours * Availability Factor
Exemple Résolu
A hydropower site with 5 m3/s flow, 30m head, 85% turbine efficiency, 90% availability.
- 01Power: 5 * 30 * 9.81 * 0.85 = 1,250.8 kW
- 02Annual energy: 1,250.8 * 8,760 * 0.90 / 1,000 = 9,857 MWh
- 03Homes powered: 9,857 / 10.5 = 939 homes
Questions Fréquentes
What is head in hydropower?
Head is the vertical distance water falls from the intake to the turbine. Higher head means more potential energy. Run-of-river systems have low head; dam-based systems can have high head.
Is hydropower truly renewable?
Yes, hydropower uses the natural water cycle. However, large dams can impact ecosystems, fish migration, and sediment flow. Run-of-river systems have less environmental impact.
What is the capacity factor of hydropower?
Hydropower has very high capacity factors of 40-60% for conventional dams and up to 90% for some run-of-river installations, much higher than wind or solar.
