One disadvantage of small pumped hydro energy storage is the investment cost, given the low storage capacity. Small PHES indeed suffers from scale effects [13]. The method developed considers natural opportunities, such as existing lakes and natural terrain depressions, which could be operated at a limited cost.
The MW output will depend on the amount of water, the flow rate, the height which the water falls and the force of gravity. The efficiency of a hydro scheme depends on how it converts power available from water into electricity. Maximum efficiencies can be up to 80% but for smaller schemes a more realistic aim is 40%.
