Schemat drogi energii

Power plants produce energy by supplying it mostly to the transmission (400 and 220 kV) or distribution networks (110 kV).

The LV (extra-high voltage) transmission lines - 220 and 400 kV - transmit energy to the LV/HV (extra-high voltage/high voltage) substation, where the voltage is transformed to 110 kV.

HV (high-voltage) lines - 110 kV - transport energy over distances not exceeding several dozen kilometers to HV/MV stations (high-voltage/medium-voltage).

Through MV lines (medium-voltage) - 6, 10, 15, 20 or 30 kV - energy is supplied to the MV/LV stations (medium-voltage/low-voltage).

Via LV lines (low-voltage) - 230/400V - energy goes to end users, e.g. households.
