The Port of Seattle is on its way to becoming the greenest port in North America, with a goal to phase out seaport-related emissions by 2050 starting now. The Port is advancing an innovative solution to bring shore power to its downtown waterfront cruise terminal at Pier 66. This will provide clean electricity to ships at the dock and helps sustainably grow the cruise industry in Seattle—an essential economic driver in the region. Shore power at Pier 66 will mean all three cruise berths in Seattle are electric!
To be the greenest and most energy-efficient port in North America, shore power is emerging as the most effective technique to reduce Port-related maritime air emissions here in the Northwest. The project would significantly reduce greenhouse gas emissions from cruise vessels at berth, improving air quality for maritime workers and residents. Providing shore power connections to vessels allows them to turn off diesel engines while at the dock, which reduces air pollution and greenhouse gas emissions that contribute to climate change.
The objective is to provide shore power capable berths that allow maritime customers to connect cruise vessels to City Seattle Light and eliminate air emissions at the dock and reduce overall emissions in Elliott Bay.
This project requires environmental permitting and review. Permits and approvals include:
- State Environmental Policy Act (SEPA) Review
- City of Seattle Shoreline Substantial Development Permit
- City of Seattle Construction Permit
- U.S. Army Corps of Engineers
- Washington Department of Fish and Wildlife
- Muckleshoot Tribe
- Suquamish Tribe
Shore power will be operational at the Bell Street Pier Cruise Terminal at Pier 66 prior to the 2024 cruise season.
Estimated Project Costs
Total estimated cost for this project is $44 million.
This project is supported in part by nearly $3 million in grant funding from the U.S. Environmental Protection Agency Diesel Emissions Reduction Act, the state of Washington Department of Ecology, and the TransAlta Centralia Coal Transition Board.
July 2023: The Pier 66 shore power submarine cable arrived in Elliott Bay in mid-July. The team tested the cable and is getting ready for the project construction this fall.
