Shore Power

March 2018 Shorepower Summary Chart

March 2018 Shorepower Summary Chart

In 2008, the State of California Air Resources Board (CARB) put into effect new regulations, requiring reductions of air pollutants emitted from ships docked (at-berth) at most California ports. The key requirements of the regulation include emission reductions of 50% starting in 2014, 70% starting in 2017, and 80% starting in 2020. Grant funding awarded to the Port requires emission reductions additional to those required by the CARB regulation.

Shore power provides high voltage electrical infrastructure in the Port of Oakland Maritime area, so that ships can plug into the electric grid while docked. Connecting to the electric grid dramatically reduces emissions from docked vessels. The infrastructure generally runs from the Port's main substations to on-terminal substations and, from there, to the terminal wharves. Power is extended down to the wharves, where vaults with electrical connections will provide the interface (outlets) for ocean going vessels (plugs).

Shore power is available at the following marine terminals/berths:

Shore Power Rates

The Port of Oakland adopted utility rates for shore power usage. These rates and charges include a rate of $267 per hour (plus applicable taxes) and a vessel commissioning charge of $3,600. These rates are further outlined by Port Ordinance. Infrastructure at Berths 60-63, and 68 is not owned or managed by the Port. For utility rates at these berths, please contact the terminal operator.

There is a link to the Port Ordinance, there is a new Ordinance as of March:

Vessel Commissioning

Berths 20-24, 25-26, 30-32, 35-37, 55-59

Ships that plan to call the Port of Oakland and intend to plug into shore power at these berths must be commissioned by the Port prior to plugging into the shore power system. Commissioning refers to the first time a unique vessel plugs into the shore power system. Shipping lines should notify both their terminal operator partners and the Port when a vessel is scheduled to arrive in port and needs to be commissioned. Only vessels commissioned by Port's Commissioning Agent will be allowed to plug in to the Port's shore power system. The Port charges $3,600 per commissioning event for each unique vessel. Commissioning must repeat until the Port issues a Notice of Completion of Vessel Commissioning to the vessel owner/operator. Power is additional to the commissioning cost (see Shore Power Rates above).

Berths 60 - 63 & 68

The shore power system at these berths is connected to a power grid not owned or managed by the Port. Therefore, the Port does not require vessel commissioning at these berths and does not plan to be involved with such commissioning. However, the Port strongly recommends that shipping lines and terminal operators for these berths coordinate closely to perform a vessel commissioning process.


For shore power infrastructure constructed by the Port, Port Tariff 2-A (Item 02500) sets forth various requirements and charges for maintenance of the shore power infrastructure and compliance with grant requirements. Please consult Tariff 2-A for more detail.
