3Overview of U.S. Natural Gas Pipeline Network
- There are more than 160 large natural gas
pipeline systems in the U.S. - These systems represent over 200,000 miles of
transmission lines and over 100 trillion cubic
feet per day of transport capacity. - There are more than 1,500 local distribution
companies in the U.S. that deliver gas directly
to the consumer - There are over 3,000 natural gas producers, 500
of which account for 90 percent of natural gas
reserves in the U.S. - There are over 1,500 compressor stations on the
network - and 600 Natural Gas Processing Plants
- and 410 Underground Storage Facilities
- and 100 Liquefied Natural Gas Storage (LNG)
facilities.
4U.S. Natural Gas Pipeline Profile
- Interstate vs Intrastate Pipelines
- Gathering System -- Gas Processing Plant --
Mainline Pipeline System -- Underground Storage
-- Local Distribution System - Size of pipelines range from 16-42 inches on
mainlines, 2-16 inches for LDCs - Hubs or Market Centers provide interconnections
among pipelines

6Local Distribution Companies are the Connection
Between Interstate Pipelines and End Users
7Local Distribution Company Rates
- Represents the costs of moving gas from the
"citygate" to the consumer - Generally cost based rates, but performance based
rates are seen. - Depending on the state, transportation and
merchant functions may be separated. - The cost of gas is a simple pass-through to the
consumer
8Supply Reliability
- Ownership of assets equated to control of supply
- Market system relies on diversification and
flexibility - alternate transportation routes
- transportation and storage are both substitute
and complementary services - commercial arrangements
- Supplier performance / Supplier of last resort
9Average Transmission and Distribution Costs Have
Declined for Most End-Use Sectors
10 Financial Transactions are no Longer Closely
Tied to the Flow of the Commodity
11Restructuring of Pipeline Services - Order 637
- Removed price cap on short-term capacity releases
- Encouraged differentiated peak and off-peak rates
- Requires parking and lending services as a way to
avoid imbalances - Pipeline should minimize operational flow orders
- Revised rules of right of first refusal
12Current Pipeline Policy Issues
- Negotiated rates and terms and conditions of
service - Rate design
- Capacity turnback
- Mergers and affiliate relationships
13To Obtain Transportation Services
- Step 1. Reserve capacity (via contract) with the
pipeline or a releaser of capacity - Types of contracts
- Long-term firm transportation (FT)
- Short-term firm service
- Interruptible (IT)
- Capacity release (firm or recall)
- Step 2. Nominate to use capacity
- Step 3. Confirmation of nomination by the
pipeline company - Step 4. Gas flows are scheduled by the pipeline
company
14Capacity Turnback Defined
Shipper action of reducing or returning of firm
transportation capacity to the pipeline company
at the expiration of the contract.
15Shippers ReassessedTransportation Requirements
in the Late 1990s
16Emerging Issues for Interstate Transportation
Market
- Does the current formula for computing regulated
rates send the right market signals? - How, when or will the pricing structure change
from cost of service rates to market based rates? - Shifting risk - capacity turnback
- Regulation v. Competition -- Whats the right
balance? - Encourage addition of capacity without excessive
cross customer class subsidization
17Market Changes Affected Physical System
Utilization
18Trends in Firm Transportation Contracts
- LDCs hold the bulk of contracted capacity
- Contract expirations are significant
- Shippers want flexibility and reliability
- In the aggregate total commitments have increased
slightly - However, pipeline construction has outpaced
contracted capacity - The average length and size of long-term
contracts have decreased - Market concentration varies by region
19Most Firm Transportation Capacity is Held Under
Long-term Contracts
20Interruptible (Non-Firm) Service for Natural Gas
- Increases system load and utilization
- Efficient use of pipeline facility
- Price of interruptible (Non-Firm) service for
natural gas is typically heavily discounted
because service is not guaranteed - When heating load is light due to mild winter
weather, interruptible service may not be
interrupted. The service may appear to be firm.
21Capacity Release
- Order 636 ordered pipelines to establish release
programs (EBBs). - Shippers are now able to release or resell
their firm capacity rights. - Referred to as the secondary market in pipeline
capacity. - Holders of firm capacity initiate the release and
specify terms. - Competes with interruptible transportation
service offered by the pipeline. - The rate structure in Order 636 increased the
cost of reserving capacity.
22Advantages of Using the Release Market
For the releasing shipper
- Allows shippers to respond quickly to market
changes. - Includes flexible terms re amount of capacity
and duration of release. - May set specific pricing terms, subject to
regulated cap. - May reserve the right to recall the capacity.
23Advantages of Using the Release Market - Cont.
For the replacement shipper
- Moderate lead time required
- Flexible terms re duration of contract
- Ability to obtain capacity - even though the
pipeline may be fully reserved - Rates for released capacity are often heavily
discounted
24Drawbacks of the Capacity Release Market
- Coordination of multiple contracts can be
difficult. - Revenues may provide only a partial offset for
the high cost of reserving capacity. - Released capacity may be unavailable.
- Only limited price discovery is possible.
- Interruptible transportation may have competitive
edge.
25Average Utilization Rates into States Varied in
2000
26As of Sept. 2000, Proposed Pipeline Expansions
2001-2003 (70 projects, 20 Bcf/d)
27Interstate Pipeline Companies Serving the
Northeast
28Natural Gas Transportation Nomination Schedule

29E- business Speed is Key
- Auctioning pipeline capacity via the internet
- Bids need to be made, offers accepted and
contracts finalized - QUICKLY - Submit nominations, perform scheduling
- Facilitate communication - reduce costs of
information and price discovery - Key Question Should on-line auctions be
administered by a third party? - Identify alternative routes
30Retail Restructuring
31Issues in Retail Restructuring
- Do the benefits of choice outweigh the cost?
- Should all services be offered competitively?
- How should services be priced?
- Obligation to serve.
- Who should pay for the transition costs?
- Marketers and local distributors - a level
playing field? - Reliability
- Business Standards
32Restructuring of U. S. Retail Markets
- Residential and small commercial consumers are,
to varying degrees by state, acquiring choice of
supplier. - Electric generators, industrial and large
commercial customers have effectively had supply
choice for a number of years.
33Over Half of the States Have Residential Retail
Restructuring Programs
About 22 Percent of Eligible Customers are
Participating
34Retail Restructuring Varies Across the U.S. for
Several Reasons
- States Act Independently of Each Other
- Political/Economic Objectives Differ
- Regulatory Structures Differ
- Market Size to Attract Energy Providers
35Pros and Cons of Customer Choice
- PROS
- Increases competition
- Potential for customer cost savings
- Encourages new services
- Leads to greater market efficiency, as market
signals are conveyed more directly
- CONS
- May result is reduced supply reliability
- Increased price volatility
- Customer burden - some don't want choice
- May reduce supply reliability
- May lead to higher prices
- Retail market may not be a "level playing field"
36Retail Unbundling - May Include More than Supply
Acquisition
- Retail unbundling may evolve to include the
following traditional distributor services - Storage
- Metering
- Balancing
- Standby service - "supplier of last resort"
37Residential Customers Can Benefit From Effective
Information Programs
38Canadian Regulators Expect the Following
Developments in Canada
- Increased reliance on market solutions
- Competitive pipeline projects
- Pipeline capacity shifting to marketers
- Light-handed regulation
- Market-based tolls
- Continued growth in exports to the U.S.
39European Natural Gas Markets
- Gas service is often combined with other services
- water, electricity, telephone, cable - Regulation is extensive and varies by country
from government legislation, public ownership,
regulatory agencies and taxation - Concession or franchise giving the service
provider the exclusive right to operate in a
specific area in return for the obligation to
serve in that area. - Prices generally set by the market value of
competing fuels. In some cases the costs of
providing the service are also determining
factors. - Distinction between transmission and distribution
not always clear - Current debate (and some steps toward) third
party access
40Similarities Between the U.S. and U.K. Gas Markets
- Heavy reliance on domestic sources of supply
- Open access (third party access) prevalent
- Federal regulations but private ownership
throughout the gas chain - Retail unbundling underway
41The Following Policy Objectives are Incorporated
to Varying degrees in European Gas Markets
- Economic efficiency
- Security of Supply
- Social Objectives
- Environmental and climate protection
42The Reform Process in Europe The Gas Directive
- Opens-up European gas markets, both within and
across geographic boundaries - Enable large gas consumers to select their
supplier. - Sets minimum levels, implementation is determined
by each country - To date on transmission access, but movement to
open distribution is underway, but varies by
country.
43Unbundling of Gas Services in Europe
- Great Britain - retail choice is underway both at
transmission and distribution level - Germany - taking steps toward retail choice by
abolishing exclusive concessions for gas service - Italy, Austria, Switzerland - limited unbundling
at the transmission level - Spain - limited unbundling (third party access)
is being implemented - Ireland, Netherlands - moving toward unbundling
44European Gas Markets
- LDCs currently have limited choice of gas
suppliers - Most countries are dominated by one transmission
company - Demand is highly seasonal and access to storage
facilities for third party providers is needed to
successfully enter the market - Residential sector accounts for the largest share
of gas consumption (26-45) - Current structure is based on exclusive
arrangements between supplier and customer. - Most pipelines are merchants
- Ownership of LDCs is mostly public, but private
ownership is becoming more widespread
45Incentives May Be Different in Public vs. Private
Ownership of Transmission or Distribution
- Private Ownership - may be interested in
maximizing profits - Public Ownership - may be interested in lowering
consumer prices or, may be inclined to maximize
profits in order to cross-subsidize other areas - Alliances, affiliations and other corporate
combinations can reduce risk and exposure to
changing markets - also may be benefits, e.g.
economies of scale in obtaining gas supplies.

66Why Are Analysis Tools of Natural Gas
Infrastructure Needed?
- Industry and others want to how natural gas
marketing and transmission has been impacted by
restructuring. - Market participants must now make their own
arrangements for shipping gas. - Want to know about available transportation
options - What services are available to them from whom.
- Pipelines are interested in capacity levels on
existing routes on which they might propose
expansions. - Knowing the current infrastructure is necessary
for planning for demand projections of 32 Tcf
demand by 2020. - Assessing impact of infrastructure bottlenecks
and disruptions.
67Examples of Infrastructure Analysis
- The capabilities of the various interstate
pipeline systems that make up a large part of the
U.S. natural gas pipeline network. - Usage levels on these pipelines. To what degree
has it changed since the start of the decade and
why. - Pipeline expansions - completed since 1990 and
proposed through 2000. Driving forces? - Factors that have had a major impact on how the
natural gas pipeline network now operates, i.e.
FERC Order 636, Market Centers, Electronic
trading, etc.
68Components of the Analysis of Infrastructure
