Equipment cost is the cost of the machine sets consisting of pump/turbine and motor/generator. Gravity storage requires similar mechanical equipment used by pumped hydro storage system. This includes pump, turbine, and motor/generator. Several types of turbines can be used to convert kinetic energy, of the following water, to rotational energy.
