PORT OF SEATTLE 
MEMORANDUM 
COMMISSION AGENDA  STAFF BRIEFING 
Item No.        7c 
Date of Meeting     May 24, 2011 

DATE:    May 17, 2011 
TO:     Tay Yoshitani, Chief Executive Officer 
FROM:    Dave Soike, Director, Aviation Facilities and Capital Program 
Wayne Grotheer, Director, Aviation Project Management Group 
SUBJECT:  Briefing of the Electrified Ground Support Equipment (EGSE) Project at
Seattle-Tacoma International Airport (Airport) 
BACKGROUND:
The Airport is moving forward with the EGSE project with the goal to replace fossil
fueled GSE with battery powered equipment. There are currently approximately 650
individual pieces of fossil fueled GSE at the airport that will potentially be replaced. An
airline consortium agreement is being negotiated for operation and management of the
electrified fleet by a third party, from whom the airlines will lease the GSE. The
consortium will maintain the GSE and supporting infrastructure for an estimated twenty
years, at which time the airlines may purchase the electrified GSE for its remaining book
value. The consortium agreement will be brought to Commission for approval prior to
staff obligating any funds. 
The Port has obtained a U. S. Department of Energy (USDOE) grant through the Clean
Cities Coalition in the amount of up to $5 million, which will be used to pay for the price
difference between conventional GSE and the EGSE. Staff is also attempting to obtain
additional Voluntary Airport Low Emissions (VALE) grants from the Federal Aviation
Administration (FAA) to pay for part of the infrastructure costs. The USDOE grant must
be obligated by December 12, 2011; therefore, staff intends to solicit pricing for the
EGSE and use the USDOE grant funds as a down payment for EGSE that is ordered
before the grant deadlines. Legal staff has determined that a down payment for
equipment is appropriate. The grant funds will only be used to pay for the difference
between fossil fuel equipment and battery powered equipment. Although we plan to
order the EGSE this year, delivery of the EGSE will occur over the next two years as the
infrastructure is installed. The Request for Quotes for the rolling stock will be issued
within the next month and the total value could be as much as $30 million, depending
upon airline participation.

The total project consists of five basic procurements: rolling stock, charging units,
electrical meters, long lead electrical equipment, and major construction to install all the
infrastructure components and upgrade power capacity where needed. The total costs of
this project will depend upon participation by the airlines, but could be as much as $50
million if there is 100 percent participation. Staff will return to the Commission to
request authorization of the Port agreement with the consortium, purchase of rolling stock
and chargers, and the remaining design and construction funds.
