Onshore Power Supply

Onshore power supply (OPS) is the European term for shore power, the shore-to-ship electrical connection that lets a berthed ship turn off its diesel auxiliaries and draw grid power, equivalent to cold ironing and the US alternative maritime power. The EU Alternative Fuels Infrastructure Regulation requires core TEN-T ports to provide OPS for container and passenger ships by 2030, paired with the FuelEU obligation on those ships to use it. Systems follow IEC/IEEE/ISO 80005, with high-voltage shore connection sized to the ship’s hotel and reefer load.
