Shore Power for Ocean-going Vessels

This page reviewed September 12, 2018

Overview

In December 2007, the Air Resources Board (ARB) approved the "Airborne Toxic Control Measure for Auxiliary Diesel Engines Operated on Ocean-Going Vessels At-Berth in a California Port" Regulation, commonly referred to as the At-Berth Regulation. The purpose of the At-Berth Regulation is to reduce emissions from diesel auxiliary engines on container ships, passenger ships, and refrigerated-cargo ships while berthing at a California Port. The At-Berth Regulation defines a California Port as the Ports of Los Angeles, Long Beach, Oakland, San Diego, San Francisco, and Hueneme. The At-Berth Regulation provides vessel fleet operators visiting these ports two options to reduce at-berth emissions from auxiliary engines: 1) turn off auxiliary engines and connect the vessel to some other source of power, most likely grid-based shore power; or 2) use alternative control technology that achieve equivalent emission reductions.

What's New

September 6 & 17, 2018 - 2nd Public workshops

CARB staff is hosting workshops to discuss draft regulatory concepts for the At Berth and At Anchor Regulation. A workshop will be held on September 6, 2018, in Oakland. Another identical workshop will be held on September 17, 2018, in San Pedro. Staff intends to discuss refined concepts, draft regulatory language, estimates of emissions and health risk reductions, preliminary cost analysis, and to solicit early scoping feedback on the environmental impact analysis which will be prepared for this regulatory action. Additional information will be posted here prior to the workshops.

August 14, 2018 - Preliminary Cost Analysis

CARB staff performed a preliminary cost analysis for the Control Measure for Ocean Going Vessels At Berth and At Anchor Regulation and solicited stakeholders to assist with the preliminary cost estimates. A survey requesting information on shore power infrastructure costs was sent to ports in Spring 2018 and a survey requesting vessel specifics and shore power cost information was sent to vessel owner/operators in Summer 2018 to assist staff in understanding the potential costs and savings to industry that could be incurred by the Regulation. Preliminary cost information is based on staff's analysis of data, including survey results. Preliminary cost estimates are subject to change as staff receive updated information. Vessel and port survey data is reported directly from ports and vessel fleets, and should not be cited or quoted or taken as a final cost estimate. For detailed information on the preliminary cost estimates, please refer to the link provided.

August 14, 2018 - Draft Regulatory Concepts

On July 19, 2018, CARB staff hosted a webinar with industry stakeholders to discuss staff's draft preliminary concepts for the Control Measure for Ocean Going Vessels At Berth and At Anchor Regulation. The webinar walked participants through the purpose of the draft regulatory concepts and preliminary implementation schedule, the method for determining which vessels and ports will be included in the regulation, and responsibilities for vessel owners/operators, terminals, ports, and alternative technology providers. For additional details, please refer to the link provided.
