Name
Concurrent Technical Session 5A: Shore Power Connections in BC
Date & Time
Thursday, April 20, 2023, 9:20 AM - 10:00 AM
Description

Seaspan Ferries provides commercial ferry service from Vancouver Island to the Lower Mainland. They move over 50% of goods to Vancouver Island through 18 daily trips and 7 day/week operation. With continued focus on emission reduction, Seaspan actively sought new technology for their fleet to lower their carbon footprint. As of March 2022, Seaspan Ferries added two LNG/battery electric vessels into their fleet. The vessels have been developed with a state-of-the-art modular stacking battery system in partnership with Corvus Energy. The vessels currently have a 2MW battery for their propulsion system but can increase to a total of 5MW. With the move to larger battery systems, BC Hydro has been partnering with Seaspan on exploring the implementation of shore power connections for their vessels. The unique charging scenario of “fueling-up” during the ~1hr berth windows without impacting operations is an important balancing act. BC Hydro has provided study support for bringing in optimal shore power connections and are looking to offer incentive support through the Low-carbon incentive program to implement these services. Additionally, BC Hydro has helped adjust our shore power rate with the BC Utility Commission with amendments for Seaspan and other marine organizations to utilize our shore power rate. The importance of this project and the value of electrification for marine vessels will have long term benefits for the collective industry. The early analysis shows that these two vessels will look to reduce their GHG emissions by 2,960tCO2e/yr while increasing electrical consumption by 4.2GWh/yr. Given the incredibly GHG intensive industry and BC Hydro’s ~98% clean electricity, there is major interest to support electrification within the sector. BC Hydro realizes there are significant challenges to electrify without impacting operations. Our continued support on this project is just the beginning for marine electrification helping to broaden decarbonization for marine customers.
