micro-hydro

Small-scale water power

Micro-hydro refers to small-scale hydroelectric power generation, typically producing less than 100 kilowatts—enough to power a single home or small community.

These systems divert water from a stream through a turbine without requiring large dams: The off-grid cabin runs on micro-hydro from the creek.

The term distinguishes modest installations from industrial hydropower projects.
