ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to (1) advertise and award a
major works construction contract for Phase 2A (Concourse A) of the Electric Ground Support
Equipment (EGSE) Charging Stations project (the anticipated cost of $4.6 million is within the
amount already authorized by the Commission); (2) utilize Port crews to perform construction
work.
SYNOPSIS 
The Commission previously authorized funding necessary to complete the full EGSE design
documents as well as the Phase 1 construction. This request is for the advertisement and award
of a construction contract for phase 2A; no additional funding authorization is necessary for the
construction of Phase 2A. In March 2012, the airlines approved the full project in a Majority in
Interest vote. 
During Phase 1 construction, small business was utilized and the plan is to utilize small business
again for Phase 2A construction. 
This request enables staff to complete Phase 2A of this project, which installs EGSE charging
stations throughout the Concourse A ramp area and constructs telecommunications early work
necessary for Phase 2B (Concourse B and South Satellite). EGSE Phase 2B will be a later
separate authorization request to the Commission. The Phase 2A & 2B work completes full
airport coverage to enable the phase-out of fossil-fueled ground support equipment such as
baggage tugs and aircraft pushback tractors at Seattle-Tacoma International Airport. Delta,

United and Southwest Airlines will utilize and benefit from the EGSE infrastructure provided by
this project as soon as it becomes available in 2017. 
This project will improve air quality by reducing particulate matter and carbon emissions from
ground support equipment, reduce airline maintenance costs, save fuel costs, and contribute to
the Century Agenda goal to "Be the greenest and most energy efficient Port in North America." 
Assuming full airline participation, a fuel savings of $2.8 million per year is anticipated with a
carbon reduction of up to 10,000 tons per year. 
BACKGROUND 
To accommodate recent growth in airline demand for EGSE, Port staff has divided the Phase 2
work into two construction packages (Phase 2A and Phase 2B). The EGSE charging stations can
be installed relatively quickly on Concourse A (Phase 2A) because no additional power
distribution switchgear is necessary. The phase 2B work is complex because sufficient power
distribution equipment does not currently exist to support charging stations on Concourse B and
the South Satellite. The Phase 2A work installs 20 charging stations by year-end and allows
airlines operating out of the south half of the airport to proceed with their immediate plans to
deploy EGSE in early 2017. 
The overall EGSE program consists of the following three packages: 
Phase 1 - Actual cost $14.3 million (This work is complete) 
o  Install 286 charger ports on Concourses C and D, North Satellite and Central
Terminal bag well 
Phase 2A - Estimated cost $4.6 million (This authorization) 
o  Install 76 charger ports on Concourse A 
Phase 2B - Estimated cost $17.2 million (This estimate exceeds the current authorized
budget of $30.7M and requires future commission action)
o  Install 142 charger ports on Concourse B and the South Satellite 
o  Install new Power Centers at B Concourse and the South Satellite
The Phase 2B design will be 90% complete in Q3 of 2017 and will include an updated Phase 2B
construction cost estimate. Staff anticipates returning to Commission in Q3 of 2017 requesting
an estimated $5.4 million budget increase to construct Phase 2B for a revised total project budget
of $36.1 million. The required budget increase is a result of the scheduled delay in Phase 2
construction. The Phase 2 design documents were completed in 2013. However, due to low
demand on the south half of the airport for EGSE, phase 2 construction was deferred. Demand
has since increased dramatically, with Delta, United, and Southwest all deploying EGSE in
2015-6 and demanding more charging infrastructure in the South half of the airport.
Previous Commission authorizations include $1.51 million on October 26, 2010, for preliminary
design; $8 million on April 3, 2012, to install 20 chargers at the demonstration site, order

charging units, and design the installation; and $16.2 million on October 23, 2012 to prepurchase
EGSE chargers, and execute the Phase 1 construction contract. 
Currently, Washington law allows a waiver of state sales tax on the purchase and installation of
energy-saving equipment until 2020, which will save approximately $2 million in taxes for the
entire project. 
PROJECT JUSTIFICATION AND DETAILS 
Project Objectives 
This Project will install EGSE Charging Stations at Seattle-Tacoma International Airport and
will: 
Reduce air pollutants such as particulate matter and carbon emissions 
Reduce fuel consumption by approximately one million gallons per year 
Reduce airline maintenance costs 
Take advantage of Washington state sales tax waivers that expire in 2020 for the project
elements related to utilizing electrical power vs. fossil fuel 
Scope of Work 
This authorization provides for the advertisement and award of a major works construction
contract that will install 76 charging points on Concourse A. 
Staff will return to commission in Q3 of 2017 seeking authorization for Phase 2B which will
upgrade two power centers and install approximately 142 charging points on concourse B and
the South Satellite. 
The entire program will ultimately install approximately 252 EGSE charging stations throughout
the Airport passenger terminal ramps capable of charging 504 pieces of ground service
equipment simultaneously.

STRATEGIES AND OBJECTIVES 
The Port's purchase and installation of EGSE charging stations will promote and expedite carrier
adoption of EGSE vehicles such as electric pushback tractors and tugs. Implementation of
EGSE reduces emissions at the Airport. The EPA considers electric vehicles the best alternative
vehicle fuel option for emission reductions. 
This project helps to clean the environment by reducing air pollutants such as particulate matter
and greenhouse gases, creates short-term construction jobs, and incorporates small business
opportunities to encourage small business participation in a major construction contract.

This project helps the environment by reducing fossil fuel consumption at the Airport and allows
our business partners to expand their operations. 
During phase one construction, small business was utilized and the plan is to utilize small
business again for Phase 2A construction. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Status Quo  Do not complete this project 
Cost Implications: Approximately $2.2 million in design fees will need to be expensed. 
Pros: 
(1)  No additional capital costs 
Cons:

on the south half of Sea-Tac Airport 
This is not the recommended alternative. 
Alternative 2  Complete Phase 2 of this project (Provides Full Airport Coverage)
Cost Implications: Project Cost Estimate $21.8 million 
Pros: 
(1)  Installs 218 EGSE charge ports on Concourse A, B and the South Satellite
(2)  Maximizes the reduction in carbon emissions from ground service equipment 
(3)  Allows all airlines operating out of Sea-Tac Airport to take advantage of EGSE 
Cons:
