A power plant comprising two engine groups and a main power transmission gearbox. Each engine group drives the main gearbox mechanically in order to rotate a main rotor of an aircraft at a frequency of rotation NR. A first engine group comprising two main engines is regulated on a first setpoint NR* for the frequency of rotation NR, while a second engine group comprising a secondary engine is regulated on a second setpoint W2* for power. The second setpoint W2* for power is determined so that each secondary engine operates only when a flight power Wvol necessary for the flight of the aircraft is greater than the sum of the main maximum powers WMax1 from each main engine.
