U.S. ro‑ro MV Jean Anne makes shore power history at the Port of San Diego

The MV Jean Anne has become the first U.S.-flag roll‑on/roll‑off (ro‑ro) vessel to connect to shore power, marking a significant milestone for cleaner operations at the Port of San Diego.  The achievement highlights the port’s ongoing efforts to reduce air emissions.

Operated by Pasha Hawaii, the MV Jean Anne plugged into a new shore power system that allows the vessel to shut down its auxiliary engines while at berth.  This switch eliminates most at‑berth air emissions from the ship’s diesel generators, including greenhouse gases, nitrogen oxides, and particulate matter, directly benefiting air quality in nearby communities.

The shore power installation at the Port of San Diego is part of a broader investment in clean technologies to advance continual environmental improvement.  By providing the infrastructure for oceangoing vessels to connect to grid electricity, the port is helping reduce its overall carbon footprint and support the transition to lower‑emission maritime transport.

The successful commissioning of shore power for the MV Jean Anne is expected to pave the way for more vessels to plug in at the Port of San Diego in the coming years.
