Abstract: A pressure of a working compressed fluid is released into a liquid circuit to drive a turbine for energy generation, comprising a compressor and a primary tank of high pressure, a first main tank of liquid and a second main tank of liquid, an auxiliary tank of liquid, a turbine of liquid located between the first and the second main tanks, and at a lower level than that of the bottom of the main and second and auxiliary tank, to ensure that the pressure inside the tanks forces the liquid in the proper direction through the turbine, a network of pipelines with their respective valves, such as inlet valves, outlet valves, control valves or pressure-regulating valves, as well as ventilation valves; where the operation is performed in short cycles and at a constant pressure by means of a control system that acts on at least one pressure-regulating valve.
