Seattle Port unveils electrification ambitions

Developed in collaboration with The Northwest Seaport Alliance and Seattle City Light, the strategy outlines the investments and infrastructure upgrades needed to achieve a zero-emission maritime sector by 2050.

“Our partnership with The Northwest Seaport Alliance and Seattle City Light is critical to ensuring there’s enough power to meet the increasing demand for bringing electricity to the waterfront to serve ferries, trucks, cargo handling equipment and the Coast Guard,” said Port of Seattle commissioner Fred Felleman.

The report projects a fourfold increase in peak power demand by 2050 and highlights the urgency of continued planning and investment in clean energy systems.

Key findings emphasise the growing importance of shore power for oceangoing vessels and warn that current electrical capacity planning limits will be exceeded unless action is taken.

“Installing shore power at marine terminals so that cruise and cargo ships can turn off their engines while at dock is a key part of the Port of Seattle’s commitment to becoming the greenest port in North America,” continued Felleman.

The strategy, shaped through site-specific assessments across Elliott Bay, the Duwamish River and other maritime zones, provides eight key recommendations covering infrastructure planning, clean technology and financial strategies.

Estimated investments range from US$208 million to US$457 million by 2050, including upgrades to both utility distribution systems and infrastructure such as transformers and substations.
