Ship operators and port authorities use shore power connections to supply berthed vessels with electricity from the landside grid, eliminating the need to run auxiliary diesel engines during port stays. The system—also known as cold ironing or Alternative Maritime Power (AMP)—relies on standardized high-voltage connectors and cabling that feed onboard systems such as HVAC, lighting, and refrigeration. For port cities, the benefit is a direct reduction in local air pollution and noise; for shipowners, fuel savings accumulate over extended port calls. The term refers specifically to the physical interface between ship and grid, distinct from the broader shore power installation that includes transformers and distribution infrastructure on the quayside.
