A hydraulic power network is a system of interconnected pipes carrying pressurized liquid used to transmit mechanical power from a power source, like a pump, to hydraulic equipment like lifts or motors. The system is analogous to an electrical grid transmitting power from a generating station to end-users. Only a few hydraulic power transmission networks are still in use; modern hydraulic equipment has a pump built into the machine. In the late 19th century, a hydraulic network might have been used in a factory, with a central steam engine or water turbine driving a pump and a system of high-pressure pipes transmitting power to various machines.

Το hydraulic power μεταφράζεται ως «υδραυλική ισχύς», βλέπω στην IATE. Θα μπορούσε άραγε να μεταφραστεί ο όρος του τίτλου ως υδροηλεκτρικό δίκτυο;
