Why it is necessary?
The Onshore Power Supply (OPS), also known as Cold Ironing, consists in connecting to the general electrical grid the vessels berthed in ports. This allows to turn off their auxiliary engines, which would otherwise be used to generate the energy required to meet the different onboard necessities.
OPS is an alternative for maritime transport to onboard power generation, which allows to considerably reduce the noise and the emission of pollutant gases produced by berthed vessels.
This advantage is particularly relevant taking into account that about 40% of world’s population lives within 100 km of the coastline, and the emission of pollutant gases is a major environmental risk to health that causes more than 500,000 premature deaths in Europe every year.
 Provoked by the long exposure to PM2.5 and NOx. Data from the European Environment Agency (EEA).
