This invention concerns an electrical energy distribution system. The system incorporates ‘ride-through’ capability, comprising: a supply side for supplying energy in the form of direct current at a supply voltage, a delivery side for delivering energy, having plural connection ports for selective connection to respective electrical energy loads. Wherein each connection port includes electricity conditioning circuitry to deliver and vary electrical power supply to a load connected at the port. And further comprising a bank of charge storage devices arranged in series and connected across the supply voltage.
