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

FUTURE ENERGY DELIVERY SYSTEM

11


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


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.
