Disclosed are a power distribution method for a hybrid vehicle in consideration of electric field load, and an apparatus thereof. The power distribution method for a hybrid vehicle includes the steps of: receiving an output power value of a first voltage network side of a converter and a power distribution ratio value for an engine and a drive motor which assists power of the engine; calculating a fuel consumption rate and an SOC change amount for a predetermined driving cycle by using the power distribution ratio value and the output power value; and determining an optimal power distribution ratio value and an optimal output power value, at which the SOC change amount satisfies SOC constraints and the fuel consumption rate becomes minimum, wherein the hybrid vehicle includes a first voltage network and a second voltage network electrically connected by the converter. The power distribution method for a hybrid vehicle in consideration of electric field load, and the apparatus thereof can design an electric network structure capable of minimizing fuel consumption.
