Shore power technologies, also known as cold ironing or Alternative Maritime Power (AMP), enable the connection of ships in port to shore side electricity to power on board services. This enables ships’ diesel generators to be switched off, thereby reducing noise and emissions, such as particulate matter, nitrogen, sulphur and carbon oxides, and volatile organic compounds.
Standards and regulations
Since 2012, an international standard on shore power, (ISO/IEC/IEEC 80005-1), has been in place to ensure worldwide compatibility between ports and vessels.
Shore connection is included in the California Air Resources Board regulations, which requires operators to reduce at-berth emissions from ocean-going vessels’ auxiliary engines at California ports by 80 per cent by 2020.
The EU Directive 2014/94/EU on the Deployment of Alternative Fuel Infrastructure requires EU ports to progressively equip berths to be shore power-ready by 2025.
