IAH Electrical System - Existing Challenges
Complexity
Each terminal is served by multiple service points and meters
Reliability
Multiple, aged terminal feeders operating at 50% load or higher
Manual throw over (MTO) switches installed at some terminals in lieu of Automatic throw over (ATO) switches
Ownership
Current distribution system prevents effective load aggregation by COH/HAS for alternative delivery strategies

IAH Terminal Redevelopment Program
EUL and EI - Overview
Electrical Utility Landside (EUL) Summary Objectives
To provide a pathway to install electrical & fiber conduit, racks and innerduct with pullstrings for future conductors & fiber optic cables from Terminal A to MLIT. Fiber infrastructure to continue to old Tracon west of Terminal A.
Energy Infrastructure (EI) Summary Objectives
To reduce operating load on existing 12.47kV feeders to less than 50% rated capacity to improve reliability
HAS acquire terminal distribution system ownership to support new Energy Infrastructure initiatives
Projected Demand:
Element A: IAH Loads
40MW projected aggregate demand for the IAH Central Terminal Area (CTA) – HAS Load
Min. 5MW UAL Load
Element B: Up to approx. 120MW CoH Loads (inclusive of HAS Loads)

Energy Infrastructure Project - Option 1
Off-Site Energy Source
Feeds to 138kV/12.47kV
substation; to electrical power
station (EPS) and EUL
Infrastructure to CTA
Pros:
1. Increased Reliability of
Service - Feeder Loads
2. Reduces cost of
Service, eliminates T&D
charges;
3. Supports HAS goal to
centralized CTA Power
distribution via Electrical
Power Station.
Cons:
1. Capital expense,
2. Complexity
3. long lead time to design
and construct new 138
kV feeders by CPE.

Energy Infrastructure Project Delivery Methods
20
IAH Terminal Redevelopment Program
Project Delivery Method Considerations
■ A Project Delivery Method is the contractual structure (exclusive of the
financial arrangements) of how the final project is delivered to the Owner. The
various project delivery methods are often consolidated into four (4) basic
approaches:
■ Design-Bid-Build (DBB) - the traditional project delivery method, which involves three sequential project phases: design, procurement, and construction
■ Construction Manager at Risk (CMAR) – a project delivery method in which the construction manager acts as a consultant to the owner in the development and design phases, but assumes the risk for construction performance as the equivalent of a general contractor holding all trade subcontracts during the construction phase
■ Design-Build (DB) – a project delivery method that combines services with construction performance under one contract
■ Design-Build-Operate-Maintain (DBOM) – a project delivery method that combines design services with construction performance under one contract plus performance of operation and maintenance of built facilities
■ Project Delivery Method w/ Financing
■ DBOMF / Public Private Partnership is a delivery method whereby a public entity partners with a private entity for the purpose of delivering public infrastructure.
