The invention relates to a pumped-storage power plant, comprising at least one first reservoir (H1, H2), a second reservoir (H3), a flow path (303) for a liquid, which flow path connects the at least one first reservoir (H1, H2) to the second reservoir (H3) and within which a mechanically driven generator (104, 204, 304, 214, 404) of electrical energy is arranged. According to the invention, the at least one first reservoir (H1, H2) comprises a cavity (101, 201, 301, 401) that is closed in a pressure-tight manner and that is partially filled with liquid, the region of the at least one first reservoir (H1, H2) not filled with liquid is filled with a gas under pressure (P1), wherein the pressure (P1) is greater than a pressure (P2) in the second reservoir (H3), and the mechanically driven generator (104, 204, 214, 304, 404) of electrical energy is arranged in the flow path in such a way that the mechanically driven generator of electrical energy either separates the at least one first reservoir (H1, H2) from the second reservoir (H3) in a pressure-tight manner, releases a flow direction from the at least one first reservoir (H1, H2) to the second reservoir (H3), or releases a flow direction from the second reservoir (H3) to the at least one first reservoir (H1, H2) as a pressure generator. |
