Port of San Diego Completes Shore Power Expansion at Cruise Ship Terminals, Two Cruise Vessels Plug in for First Time

Two cruise ships plugged into shore power at Port of San Diego B Street Terminal.

As environmental champions, the Port of San Diego continues to improve air quality and reduce greenhouse gas emissions on and around San Diego Bay. For the first time, two cruise ships can now simultaneously use shore power in San Diego rather than running their diesel engines while at berth. Previously, only one cruise vessel could plug in. On Friday, the Disney Wonder and the Insignia were the first two cruise vessels to use shore power at the same time in San Diego.

The Port is committed to being a good neighbor. Having two shore power outlets at the cruise ship terminals will result in at least a 90 percent overall reduction of harmful pollutants (while the ships are docked) such as Nitrous Oxides (NOx) and Diesel Particulate Matter (DPM) as well as a reduction in greenhouse gas emissions. The Port is also meeting California Air Resources Board (CARB) regulations that require essentially all cruise ships calling on California ports to use shore power beginning January 1, 2023.

Insignia cruise vessel plugged into shore power at B Street cruise ship terminal at the Port of San Diego.

The Port invested $4.6 million to complete this project and worked with Cochrane Marine, LLC to purchase equipment and for construction management, coordinating, testing, and commissioning. San Diego County-based Baker Electric, Inc. installed Port-provided electrical equipment and removed, replaced, and terminated medium voltage cables.

The Port installed its first shore power outlet at the cruise terminals in 2010, making it among the first ports in California to have shore power available for cruise ships.

Doubling shore power at the cruise terminals is among many electrification efforts underway in support of the Port’s Maritime Clean Air Strategy (MCAS), the most ambitious clean air strategy of its kind in the state, and likely in the entire country. The MCAS and its “Health Equity for All” vision represents the Port’s commitment to environmental justice, specifically cleaner air for everyone who lives, works, and plays on and around San Diego Bay.

Expanding shore power at the cruise terminals is among many of the Port’s clean air efforts. Other initiatives the Port is pursuing or are underway include:

  • Installation this year of two all-electric Konecranes Gottwald Generation 6 Mobile Harbor Cranes (first all-electric cranes to operate in North America) to replace the diesel crane at the Tenth Avenue Marine Terminal;
  • The first all-electric tugboat in the U.S. will be in operation on San Diego Bay this year in partnership with Crowley. The Port is building a shoreside charging station to support the eTug;
  • A new shore power system at the National City Marine Terminal;
  • An emissions capture and control system (otherwise known as a bonnet) from Clean Air Engineering – Maritime, Inc. (CAEM), which will be able to connect to ships that are not shore power capable and reduce their emissions while at berth.
  • Transitioning all cargo handling equipment at the Port and 100 percent of short-haul cargo trucks that serve the Port’s terminals to zero emissions by 2030 – the State’s requirement is by 2035.
  • Infrastructure improvements including a 700 KW solar PV system with storage and microgrid at the Tenth Avenue Marine Terminal; and
  • Innovative technology along Harbor Drive to smartly manage cargo truck traffic passing through Barrio Logan and National City.
