Onshore Power Supply, commonly known as OPS, is the connection of ships berthed in port to the local electricity grid. OPS allows the shutdown of onboard generators which reduces the impacts caused by their use, such as the emission of pollutants, noise or vibrations.

The main objective of OPS has traditionally been to improve air quality in the port environment by reducing pollution from ships, such as NOx, SOx, PM and other substances associated with onboard combustion processes. The technology also allows for a reduction of greenhouse gases emitted by ships during their stay in port, which in turn requires that the electricity supplied comes from renewable sources. It is a technology with great potential for achieving decarbonisation in ports that will be deployed in a very significant way in the European Union in the coming years.
