For the activity “Electricity from hydropower,” does the scale of the hydropower project (large vs. small, we observe 25MW often being referenced as capacity threshold) matter?

The SAT does not distinguish between project size (large vs. small). Nonetheless, per industry best practice, small hydropower electricity plant that are <25MW are mainly run-of-river hydropower projects. Larger scale plants, in particular >25MW, typically involves upstream reservoirs in tropical regions with potential environmental or social externalities which typically can be addressed through risk assessment review by third party.
