SUBJECT:  Pier 66 Shore Power Capacity and Connection - an early Action of the Seattle
Waterfront Clean Energy Strategic Plan 
Amount of this request:                 $960,000 
Total estimated project cost:         $17,000,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to design, permit, and develop
construction documents for the Pier 66 Shore Power Project. The amount requested under this
authorization is $960,000 of a total estimated project cost of $17,000,000. 
EXECUTIVE SUMMARY 
The port is an industry and regional leader in economic development and sustainability. As
Seattle's cruise industry continues to grow, the port recognizes its responsibility and the
importance of concerted efforts to balance economic growth with sustainability. The Seattle
Waterfront Clean Energy Strategic Plan will provide a port investment strategy to protect the
environment and improve community health. Through this approach the port seeks to achieve
its vision of being the greenest, most energy efficient port in North America. 
The provision of shore power for cruise ships, is the port's greatest opportunity to reduce
greenhouse gas (GHG) emissions and improve local air quality. Currently, the port's Smith Cove
Cruise Terminal at Terminal 91 (T91) which began operations in 2009, provides shore power at
its two cruise vessel berths. The single berth facility at Pier 66's Bell Street Pier Cruise Terminal, 
which opened in 1999, does not have shore power for cruise vessels.
To enable future shore power connections by the cruise ships that call on the Pier 66, the port 
engaged and is currently working closely with Seattle City Light (City Light) to plan and provide
shore power to the Bell Street Pier Cruise Terminal. This project serves as an early-action
toward implementing the larger Clean Waterfront Energy Plan. Based on City Light's system

impact study estimates that were provided in 2018, the port estimated the total investment
required to bring power to the Pier 66 via landside infrastructure though the City's right of way
would cost approximately $30 million. Most of these estimated costs were attributed to 
infrastructure installation through the city right-of-way. 
This year, after research and exploration of lower cost approaches, port staff proposed a
submarine cable to bring the power to the facility. This alternative, which would avoid costly
street trenching, will bring power along the seafloor of Elliott Bay from Terminal 46 (T46)
directly to Pier 66. The port conducted a submarine cable feasibility study and found the
approach to be feasible. Staff shared the submarine cable feasibility findings with City Light,
who examined two options to bring power to Terminal 46 to feed the submarine cable and
minimize construction impacts to waterfront right-of-way. The cost of the preferred landside
feeder option via T46 and a submarine cable to Pier 66 resulted in a combined conceptual level
project cost estimate of $17 millionnearly a 50 percent cost reduction compared to the $30 
million landside option evaluated in 2018.
This request for funding will enable the design, development, and permitting phases of this
project to begin, inclusive of both on-site and off-site infrastructure by the Port and City Light.
The target date for shore power system completion for the project is by the start of the 2022 
cruise season. 
JUSTIFICATION 
The Bell Street Pier Cruise Terminal at Pier 66 is a single berth cruise facility in the heart of
downtown Seattle's waterfront. Pier 66 is the port's first cruise terminalopened in 1999and
is homeport to Norwegian Cruise Line and its subsidiary Oceania Cruises. This terminal, along
with the Smith Cove Cruise Terminal at T91 contributes significantly to the region's economy on
an annual basis, generating more than 5,500 local jobs and $893.6 million in business revenue
each cruise season.
In addition to its economic development mission, the port is also an industry regional leader in
sustainability and committed to addressing global climate change and improve local air quality.
In 2017 the port's Commission adopted ambitious GHG reduction targets in alignment with the
Paris Climate Agreement and is planning and implementing projects and programs to achieve
these critical air emission reductions. 
For instance, under the Northwest Ports Clean Air Strategy, the port was instrumental in efforts
that decreased diesel particulate matter (DPM) and GHG emissions from port activities by 82
percent and 20 percent, respectively, since 2005. Looking to the future in which the port and
Washington State envision a decarbonized maritime industry, the port has initiated a regionalscale
planning effort known as the Seattle Waterfront Clean Energy Strategic Plan to enable and
accommodate future needs and zero emission maritime operations. The plan envisions working
in close partnership with the Northwest Seaport Alliance (NWSA), City Light and other key
maritime energy users like Washington State Ferries and SSA Marine Inc. to holistically plan and

develop strategies to ensure availability of clean, cost effective, resilient and reliable power for
a carbon-free future.
The port's two shore power connected cruise berths are already resulting in significant
emission reductions. In 2019, 89 percent of shore power capable ships at T91 successfully
connected and avoided an estimated 4,300 metric tons (tons) of CO2. 
Expansion of shore power to Pier 66 advances the port's Century Agenda target to reduce
Scope 3 greenhouse gas emissions from Scope 3 sources, by 80% by 2050 (from 2007), and be
the greenest port in North America. The electricity demand needed to power ships berthed at 
Pier 66 is available from City Light without extensive infrastructure upgrades or transmission
changes. This project does require the port to invest in the connection from the south, but the
unique solution of utilizing a submarine cable for power delivery, instead trenching in the right
of way, significantly reduces the overall cost. 
On a cost per ton basis, assuming a 28-year infrastructure life (2022-2050) and $17 million cost,
staff estimates the cost in 2019 dollars of the cumulative carbon reduction by 2050 to be $269 
per ton if 50% of all calls to Pier 66 connected and $134 per ton if 100% of all calls to Pier 66
connected. If every single one of the shore power capable ships that called at Pier 66 in 2019
connected each year through 2050, the cost of emission avoided would be $192. As a measure
of comparison, the estimated cost per ton of CO2 reduced from the port's purchase of Green
Direct wind power from Puget Sound Energy was $61 per ton and the cost per ton of 
conservation achieved through the Airport's Stage 3 Mechanical Upgrades was $300 per ton. 
During the design development phase of this project, additional innovative solutions as well as
funding support from state and federal agencies committed to supporting clean electricity
substitution for combustion will be explored.   Cost sharing strategies with our leasehold
partner, Norwegian Cruise Line Holdings, are also being explored and will be further developed
once  design  has  sufficiently  developed.  Furthermore,  staff  will  explore  cost  savings
opportunities during design efforts  and  coordinate  with the new cruise terminal project
development at Terminal 46.
Diversity in Contracting 
For planning and design services, we are leveraging existing indefinite delivery/indefinite
quantity contracts which are fulfilling the port's previous small business program requirements.
For  the future construction phase,  the project manager will  work with the Diversity in
Contracting Department to establish direct women and minority business enterprise (WMBE)
aspirational goal for the project.
