Hydro system costs can vary widely depending on the energy needed, the head, the flow, and the distances between intake, turbine, and wherever the energy is being used. Itâs easy to look at the cost of the turbineâhome- to ranch-scale models range from perhaps $1,500 to $10,000. But that is only a fraction of the cost of the whole system, which includes intake, pipeline, turbine, tailrace, controls, perhaps batteries, inverter, etc. A fully installed hydro system for the average use of a modern household might cost $20,000 to $100,000 (or more).
