Item No.:       4f_supp 
Date of Meeting: September 22, 2015 
Concourse C  New Power Center 
Commission Briefing
September 22, 2015

Project Location 



New Power Center will serve power needs at North end of Concourse C.

Three Issues on Concourse C 
1. Existing Concourse C Power Center is close to
maximum capacity 
no power for new projects/equipment. 
2. Fire zones in Concourse C are compromised 
unsafe conditions for emergency response. 
3. Obsolete distribution equipment at existing
electrical room 
Risk of failure, no replacement parts. 
Concourse C has inadequate power capacity, and outdated equipment.

Existing Concourse C Power Center 
1. Two separate power feeds for redundancy and
reliability. 
2. Each Bus can be loaded to 1000A Maximum. 
3. Projected loads over next three years put us
over the maximum allowed load. 
No new electrified equipment. 
Impacts operations, airline tenants, ADR. 
Transformer  1500-                                                                      Transformer  1500-
2300kVA                                                                      2300kVA 
BUS A              BUS B 
MAIN CIRCUIT         TIE BREAKER              MAIN CIRCUIT
BREAKER - A                                  BREAKER - B 
Existing Power Center on Concourse C will be overloaded in 3 years.

Fire Zones 
1. Electrical Power Distribution Fire Zones. 
All equipment in a fire zone to be powered
by a power source within the same zone. 
Some Concourse C loads are currently fed
from the C1 Power Center, located in a
different fire zone. 
2. Project will re-feed loads from the new
Power Center, re-establishing fire zone
integrity. 
Project will improve safety

Electrical Distribution Issues 
1. Distribution equipment at end of Concourse C
does not have spare capacity. 
Branch circuit panels have few or no spare
breakers. 
Tenant panels are obsolete configuration with
outdated meters. 
Power for new Tenant spaces is minimally
available, installation is expensive. 
2.  Project will replace old panels and install new
distribution with ample capacity. 
Obsolete equipment and inadequate capacity cannot power future needs.

Outdated Distribution Panel 
Replacement breakers not
available  failure will
result in extended outage 

Meters not networked  
manual meter readings
required 
Modules no longer
manufactured  cannot add
new tenant services 

Obsolete equipment poses risk of unplanned, extended outages.

Risk of Status Quo 
1. Existing Concourse C Power Center projected to
be at maximum capacity within the next 3 years. 
2. New projects will not be able to install electrical
equipment. 
Airline tenant projects, ADR, operations could
be impacted. 
3. Risk of unplanned and extended outages. 
Existing equipment is reaching end of life, may
fail with no available spare parts. 
Doing nothing poses failure risks and will limit our ability to support growth.

Opportunities 
Combining this project with the eGSE Phase 2 
project for the construction phase provides
opportunity to: 
Manage one Major Contract 
Accelerate schedules for both projects. 
Reduce design and construction costs. 
Consistency of design, supply and
installation of major equipment. 
Accelerated schedule and reduced cost by combining with eGSE Phase 2.

Schedule 
Start Design              4th Quarter 2015 
Complete Design           1st Quarter 2016 
Commission Authorization    1st Quarter 2016 
for Construction 
Advertise for Construction      1st Quarter 2016 
Substantial Completion       4th Quarter 2017 

Project schedule will be complete in 4th Quarter 2017.

Project Budget 
Estimated project Cost prior to design: 
Design Cost (18.1%)       $1,900,000 
Construction Costs (81.9%)  $8,600,000 
Project Total Cost         $10,500,000 

Pre-design estimated cost of $10.5 million.
