1. An electricity generation and accumulation system, comprising:
a tank (9) for air or gas at stabilized pressure,
a duct (11) for feeding said pressurized air or gas to a plurality of pressurized auxiliary tanks (12a, 12b, 12c) filled with a liquid,
wherein the system is further provided with a plurality of water turbines (18a, 18b, 18c) calibrated according to a pressure inside a respective auxiliary tank (12a, 12b, 12c) of the plurality of auxiliary tanks with which each water turbine is associated,
wherein each water turbine (18a, 18b, 18c) of the plurality of water turbines receives pressurized water from one or more of said plurality of auxiliary tanks (12a, 12b, 12c) and sends water back to the one or more auxiliary tanks arranged downstream, with a cascade sequence, and
wherein said system further comprising a high pressure air or gas tank (4) supplying the pressurized air or gas to said tank (9) at the stabilized pressure, through a plurality of air or gas turbines (7a, 7b, 7c) that generate electricity, or dual turbines (7d) that generate compressed air to be fed in upstream of the plurality of air or gas turbines (7a, 7b, 7c) and that cause an air or gas pressure to drop between said high pressure air or gas tank (4) and said tank (9).
