Seaport Electrification

shore power · cranes · yard tractors

Ships at berth are the largest source of port emissions. About 3% of the world's ports can plug them in.

Approximate share of a port's emissions: ships at berth 40 to 60%, drayage trucks 15 to 30%, cargo handling 10 to 15%, buildings 5 to 10%. About 3% of the world's ports offer shore power; EU rules require container and cruise ships to plug in at major ports from 2030. A ship at berth draws 1 to 20 MW, a crane 0.2 to 1 MW, and port batteries run 10 to 100 MWh or more.

Finding

The biggest load at a port is the ship, and almost no ports can plug one in

Ships idling at berth produce the largest share of a port's emissions, often 40-60%, and a single container or cruise ship draws 1-20 MW. Yet only about 3% of the world's ports offer onshore power supply (International Chamber of Shipping). Europe is forcing the issue: under FuelEU Maritime, container and passenger ships over 5,000 GT must use shore power at major EU ports from 2030.

Every berth that offers shore power is a substation project, which is why ports electrify slowly. The yard is easier: electric rubber-tyred gantry cranes, terminal tractors and reach stackers are commercial, and many ship autonomy-ready. China leads that side - ZPMC builds most of the world's ship-to-shore cranes and automated terminals in Shanghai, Qingdao and Tianjin run electric, automated yards at scale.

Once the yard is electric, energy becomes a scheduling problem: cranes, tractors and berthed ships draw on the same feed, so ports add batteries and microgrids and move toward automated dispatch. The Texas Gulf Coast - Port Houston, Corpus Christi and the LNG terminals - is covered on AustinIO's Gulf Coast nexus page.
