Hydropower system, which is designed to be arranged in a body of water with a gradient in a direction of gravity between upstream water and downstream water of the body of water, comprising at least three intermediate reservoirs, of which each has a closing element for the upstream water and a closing element for the downstream water, as well as a storage area, at least one generator module, which has a working chamber, in which a drive of a generator is arranged, as well as a regulating and/or control device for, in particular cyclically, opening the one of the closing elements (122, 124) and closing the other of the closing elements (122, 124) of each of the intermediate reservoirs, characterized in that the intermediate reservoirs and the generator module are fluidly connected via at least two collecting pipes (110, 112), wherein the one of the collecting pipes (110, 112) of the working chamber supplies water from the upstream water and the other of the collecting pipes (112, 110) discharges water from the working chamber to the downstream water, wherein at any time, in normal operation, at least one of the at least three intermediate reservoirs is in a first phase, in which this at least one of the intermediate reservoirs is open to the upstream water and one of the collecting pipes between this intermediate reservoir and the generator module is unlocked and, simultaneously, at least one other of the at least three intermediate reservoirs is in a second phase, in which this at least one of the intermediate reservoirs is open to the downstream water and one of the collecting pipes between the generator module and that intermediate reservoir is unlocked, while at least a third of the at least three intermediate reservoirs is in the first or the second phase or in a transition between the phases, wherein the regulating and/or control device is configured to cyclically switch the at least three intermediate reservoirs between the first and second phases. at least three intermediate reservoirs, of which each has a closing element for the upstream water and a closing element for the downstream water, as well as a storage area, at least one generator module, which has a working chamber, in which a drive of a generator is arranged, as well as a regulating and/or control device for, in particular cyclically, opening the one of the closing elements (122, 124) and closing the other of the closing elements (122, 124) of each of the intermediate reservoirs, characterized in that the intermediate reservoirs and the generator module are fluidly connected via at least two collecting pipes (110, 112), wherein the one of the collecting pipes (110, 112) of the working chamber supplies water from the upstream water and the other of the collecting pipes (112, 110) discharges water from the working chamber to the downstream water, wherein at any time, in normal operation, at least one of the at least three intermediate reservoirs is in a first phase, in which this at least one of the intermediate reservoirs is open to the upstream water and one of the collecting pipes between this intermediate reservoir and the generator module is unlocked and, simultaneously, at least one other of the at least three intermediate reservoirs is in a second phase, in which this at least one of the intermediate reservoirs is open to the downstream water and one of the collecting pipes between the generator module and that intermediate reservoir is unlocked, while at least a third of the at least three intermediate reservoirs is in the first or the second phase or in a transition between the phases, wherein the regulating and/or control device is configured to cyclically switch the at least three intermediate reservoirs between the first and second phases.
