Washington State Ferries (WSF) is embarking on an ambitious initiative to begin the transition to an emission-free fleet through a hybrid electric ferry system. Currently, WSF operates the largest ferry system in the United States. It is also the biggest contributor or greenhouse gas emissions of any state agency in Washington, burning 19 million gallons of diesel fuel to support 24 million passengers every year.
This shift to hybrid electric ferries is in response to governor and legislative direction as well as in alignment with the agency’s own long-range planning initiatives. To transition to a hybrid electric fleet, WSF is working on the three key elements of the electrification system – building new vessels, converting vessels, and electrifying the terminals.

Vessel electrification program manager
We also have a key WSF position open for the Vessels Electrification Program Manager position which now closes on Sept. 5 at 11:59 PM. In March 2023, we plan to solicit bids from shipyard partners to convert three Jumbo MKII vessels to hybrid electric propulsion.
Summer 2022 electrification update
With new funds from the 2022 Move Ahead Washington transportation package, and other previously secured funds, WSF has now secured $1.33 billion in funds to:
build up to five hybrid electric Olympic Class vessels;
complete up to four vessel conversions; and
bring power to terminals in central Puget Sound.
This investment is critical to the health and sustainability of the state’s ferry system.
Hybrid electric vessels
WSF has nearly completed the functional design for the HEOC, through a contract with Vigor ship builders. This design work will be the basis for construction of five new vessels, each with capacity for 144 vehicles. WSF will seek competitive bids to build the HEOC vessels. For these new vessels, WSF believes that this bidding opportunity, along with plans for 11 future vessels, will generate considerable interest from the maritime industry to build these vessels in Washington state. WSF is poised to launch this Request for Proposal process in summer 2022. We look forward to securing a partner to work on this exciting project and build five new hybrid electric vessels in the state of Washington as soon as possible.
Jumbo Mark II conversions
WSF will solicit competitive bids in March 2023 to convert the three Jumbo Mark II vessels to hybrid electric. Our team estimates that the converted Wenatchee will begin service in 2024, with conversions of the Tacoma and the Puyallup to follow.
Terminal electrification
WSF continues to work with multiple utilities that provide service to the terminals. Initial engineering and design are underway to build the necessary infrastructure to charge the vessels.

Implementation schedule
The implementation schedule below shows the electrification of terminals and vessels by routes. This schedule was updated in July 2022. All dates are subject to change and are dependent upon additional funding.
Cost
Estimates in the 2020 System Electrification Plan show that it will cost a total of $3.98 billion to fund the program—adjusted for inflation in the year of expenditure. Vessel electrification is estimated at $3.7 billion and terminal electrification is estimated at $280 million.
The program is currently funded at $1.33 billion from grants, state, and federal funding. The newest, and largest, investment of $1.03 billion is from the 2022 Move Ahead Washington transportation package. The program still needs an additional $2.37 billion to be fully funded.
WSDOT and WSF are pursuing a number of additional funding opportunities at the federal, state and local levels to advance the electrification program for both vessels and terminals. To date, WSF has been awarded grants to support the conversion project including $35 million from the nationwide federal Volkswagen settlement, a $6.5 million Congestion Mitigation and Air Quality Improvement grant and a Marine Highway Project Designation and grant award of $1.5M.
Plans for action
We’ve been planning for ferry electrification for years. Both our 2040 Long Range Plan and System Electrification Plan have paved the way for how we’ll transition to hybrid electric. These documents have also been closely informed by specific requirements from the Washington State governor and legislature, outlined below.
2040 Long Range Plan
Our 2040 Long Range Plan (PDF 11.4MB), which was delivered to the Legislature in January 2019, recommends short-, medium- and long-term actions for WSF to pursue and focuses on a set of investments and service enhancements to be implemented over 20 years. One of the key recommendations is to move toward a “greener” ferry fleet with the goal of a reliable fleet that has a lighter footprint on the environment and outperforms carbon dioxide reduction targets. These goals were captured in the System Electrification Plan (PDF 4MB) in Dec. 2020.
System Electrification Plan
We developed a System Electrification Plan (PDF 4MB) that expands on the 2040 Long Range Plan (PDF 11.4MB) to evaluate alternatives and propose an efficient strategy for using hybrid electric vessels throughout the system. The plan was delivered to the legislature in January 2021.

History of community engagement
2040 Long Range plan engagement
During the development of WSF’s 2040 Long Range plan, WSF conducted extensive public outreach, resulting in participation by more than 7,400 people. Four clear themes emerged from community engagement. One of those themes, Sustainability and Resilience, showed broad support for WSF’s investment in infrastructure to maintain reliable service in a changing climate and reduce environmental impact. Public comments overwhelmingly supported “greening the fleet.” One of the top 5 priorities identified in over 2,000 public comments was broad support for WSF to design resilient and environmentally friendly vessels and terminals.
Naming our ferries
In 2021, the Washington State Transportation Commission (WSTC), conducted outreach to name the next ferry that will be built – a 144-car, hybrid electric Olympic Class vessel. Delivery of the first vessel is expected in 2027. After this public process, the Commission adopted a resolution to name the upcoming vessel the Wishkah. A similar naming process will be implemented for future vessels.
Upcoming public engagement opportunities
We will conduct community engagement activities for construction activities, including terminal electrification, and will provide information here about these upcoming activities. Stay tuned for more information about these efforts.
Electrification program
To transition to a hybrid electric fleet, WSF will:
Build 16 new hybrid vessels
Retrofit 6 current diesel vessels to hybrid
Retire 13 diesel vessels
Electrify 16 terminals
WSF will approach this transition in three key project areas over the next 20 years: vessel construction, vessel conversion, and terminal electrification.
Vessel construction
The System Electrification Plan calls for delivering 16 new hybrid electric vessels by 2040. WSF is seeking a shipbuilder to build the first five funded vessels – setting WSF on its new course – for a greener ferry system, with reduced emissions of up to 76% when the plan is fully implemented.
Vessel conversion
We are moving forward with converting our three Jumbo Mark II-class ferries, the largest in the fleet, from diesel to hybrid electric propulsion. In October 2019, the trustee administering the nationwide federal Volkswagen settlement approved up to $35 million to support retrofitting the first of the ferries from diesel to electric power. Planning and design will continue through 2022 and construction of the first Jumbo Mark II conversion is anticipated to begin in late-2023.
Terminal electrification
We are working with the five different utilities – Seattle City Light, Puget Sound Energy, Orcas Power & Light, Tacoma Power, and Jefferson PUD – that supply electricity to our terminals to supply additional power from the substations to the affected terminals. Most utilities do have enough electricity to supply the needs of ferries, but each utility has different challenges to overcome to meet this need. We’ll be working with utilities early and often as we collaborate to build a hybrid electric ferry system.
In addition, WSF is in preliminary engineering to bring power to Colman Dock in Seattle, to the Bainbridge Island and Bremerton terminals, and to the Clinton/Mukilteo route. Construction at these terminals is anticipated to start in 2025 and expected to wrap up in 2027.
Hybrid electric ferries
While WSF is one of the first – and largest – ferry systems in the US to electrify its fleet, this technology has been broadly applied throughout northern Europe with over 70 comparable vessels in service going back to 2015. In general, hybrid ferries provide additional system resiliency by implementing a second power source that allows a vessel to continue service if there are any issues with the electricity. In addition, having diesel as a secondary power source allows WSF to manage utility costs in a way that is most cost-effective while still providing GHG emission reductions. This model also facilitates an earlier transition to electrification, with the first vessels operating as hybrids prior to full terminal electrification.
Terminal electrification will take place in phases over the next 20 years, with routes in the Central Puget Sound electrifying first.
Hybrid electric ferries reduce energy consumption, maintenance costs, and emissions.
Terminal improvements (terminal electrification) and vessel improvements (vessel construction and conversion) will be required to electrify our ferry system.
A robotic charging arm will extend from the hybrid electric ferries to the terminal power source to recharge the batteries as loading and unloading takes place.
Reducing emissions
We are beginning electrification in our Central Sound routes as they are the largest emitters of greenhouse gas emissions and electrifying these urban area routes can also significantly improve air quality for local communities. Jumbo Mark II vessels currently contribute 26% of the overall greenhouse gas emissions of our ferry system, and Olympic Class vessels contribute 25%. Replacing both will reduce greenhouse gas emissions by over 50%. Converting a Jumbo Mark II vessel will reduce carbon emissions by 48,565 metric tons/year – the equivalent of taking 10,000 cars off the road.
By 2040, emission reductions will include:
Reduction in carbon dioxide emissions by 76%
Reduction in sulfur oxide emissions by 75%
Reduction in nitrous oxide emissions by 94%
Reduction in particulate matter emissions by 90%
These greener ferries have the added benefit of reducing operating costs, virtually eliminating engine noise and vibration, and reducing maintenance costs.
