Abstract: A subsea electric power distribution installation (1) comprising: —one or more MV switching apparatuses (70) electrically connected with an electric power source (50) and one or more electric loads (60), said switching apparatuses being adapted to switch a MV electric power supply (V0) to said electric loads; —electronic equipment (11, 12) operatively associated with said switching apparatuses for managing the operation of said switching apparatuses, said electronic equipment being configured to receive a LV electric power supply. The subsea electric power distribution installation comprises a centralized energy storage unit (20) including one or more storing devices (25) for storing electric energy to feed said electronic equipment (11, 12), wherein said centralized energy storage unit is adapted to receive electric power from said electric power source to charge said storing devices, wherein said centralized energy storage unit is adapted to provide an electric power supply to said electronic equipment by absorbing electric power from said storing devices.
