- The Port of Seattle mandates that by 2027, all cruise vessels homeported in Seattle must be shore power capable and utilize it, aiming to cut emissions and improve air quality.
- Shore power reduces each connected ship’s diesel emissions by 80% and CO₂ emissions by 66%, contributing to significant environmental improvements.
- A $44 million investment has enabled shore power connections at all three of Seattle’s cruise berths, allowing for simultaneous power use by multiple ships, which few ports globally offer.
- Partnerships with Seattle City Light and the cruise industry are vital to Seattle’s zero-emission vision, setting a precedent for sustainable port operations and encouraging statewide shore power policy.
In a significant move reported by Offshore Energy, the Port of Seattle has become the first port in the United States to independently mandate that all cruise ships homeported in Seattle be shore power capable, with full utilization by 2027. This goal, three years ahead of schedule, advances Seattle’s efforts to enhance air quality and reduce emissions across the Puget Sound region, creating a cleaner, more sustainable future for the community and the environment.
Impact of Shore Power on Emissions
During the 2023 cruise season, shore power helped avoid 2,700 metric tons of greenhouse gases and 0.75 metric tons of diesel particulate matter. Each connected cruise ship reduces its diesel emissions by 80% and CO₂ emissions by 66% while docked, supporting Seattle’s commitment to a zero-emission vision.
Infrastructure and Investment for Cleaner Operations
Following a $44 million investment, Seattle has equipped all three of its cruise berths for shore power, making it one of the few ports globally with the capacity to simultaneously connect multiple vessels to clean electricity. This infrastructure allows ships to turn off their fuel-based engines and operate sustainably while at berth.
Collaborative Efforts for a Sustainable Future
Collaboration with Seattle City Light and the cruise industry has been key in advancing these environmental milestones. By electrifying Pier 66 and enabling shore power across the waterfront, Seattle City Light supports the Port’s vision of sustainable maritime operations, reducing emissions and improving air quality for residents, workers, and visitors.
Statewide Policy Advocacy and Future Goals
With ocean-going vessels as significant polluters in the Puget Sound area, advocates are calling for Washington State to implement a comprehensive shore power policy. Extending shore power across Washington’s ports would further protect portside communities and contribute to long-term environmental health.
Conclusion
Seattle’s commitment to shore power sets a new standard in sustainable port operations. Through targeted investments and collaborative efforts, Seattle is demonstrating the positive impacts of clean energy on maritime industries, paving the way for a healthier community and a greener future.
