Claim:
1. A pumped storage system comprising: operating mechanisms that convert movement of water or air into work of individual high-pressure pumps, wherein the pumps pump water through water ducts from a natural body of water into a reservoir, wherein the reservoir is placed above a water level of the natural body of water; a device for conversion of a flow of water through the water ducts from the reservoir into useful work; the system further includes volumes, located at a bottom of the natural body of water and connected to the high-pressure pumps, wherein the high-pressure pumps are configured to pump water at high pressure into the volumes; a pressure accumulator for normalization of pressure in the volumes; and a buffer volume located at a coastline and located below the reservoir and above the water level in the natural body of water, wherein the buffer volume includes pressure accumulators to protect the water ducts from a pressure spike due to hydraulic impact.
