Hydropower systems. There are four main types of hydropower projects. These technologies can often overlap. For example, storage projects can often involve an element of pumping to supplement the water that flows into the reservoir naturally, and run-of-river projects may provide some storage capability. Run-of-river hydropower: a facility that
