Overview 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.

U.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

6
Local Distribution Companies are the Connection
Between Interstate Pipelines and End Users
7
Local 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

8
Supply 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

9
Average 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
11
Restructuring 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

12
Current Pipeline Policy Issues
  • Negotiated rates and terms and conditions of
    service
  • Rate design
  • Capacity turnback
  • Mergers and affiliate relationships

13
To 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

14
Capacity Turnback Defined
Shipper action of reducing or returning of firm
transportation capacity to the pipeline company
at the expiration of the contract.
15
Shippers ReassessedTransportation Requirements
in the Late 1990s
16
Emerging 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

17
Market Changes Affected Physical System
Utilization
18
Trends 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

19
Most Firm Transportation Capacity is Held Under
Long-term Contracts
20
Interruptible (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.

21
Capacity 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.

22
Advantages 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.

23
Advantages 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

24
Drawbacks 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.

25
Average Utilization Rates into States Varied in
2000

Interstate Pipeline Companies Serving the
Northeast
28
Natural Gas Transportation Nomination Schedule
Shippers Last Opportunity to Submit Intraday
Nomination (4 hrs before gas flows)
Shipper Nominates Next Days Gas (1130 am)
Natural Gas Begins to Flow (900 am)
Shipper Receives Confirmation of Scheduled
Quantities (430 pm)
Gas Day 900 am to 900 am Central Clock Time
1 Day
29
E- 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

30
Retail Restructuring
31
Issues 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

32
Restructuring 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.

33
Over Half of the States Have Residential Retail
Restructuring Programs
About 22 Percent of Eligible Customers are
Participating
34
Retail 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

35
Pros 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"

36
Retail 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"

37
Residential Customers Can Benefit From Effective
Information Programs
38
Canadian 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.

39
European 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

40
Similarities 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

41
The Following Policy Objectives are Incorporated
to Varying degrees in European Gas Markets
  • Economic efficiency
  • Security of Supply
  • Social Objectives
  • Environmental and climate protection

42
The 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.

43
Unbundling 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

44
European 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

45
Incentives 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.

66
Why 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.

67
Examples 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.

68
Components of the Analysis of Infrastructure
Adequacy
  • 1. Production capabilities and the ability to
    move supplies onto the interstate network
  • 2. Transmission of gas along the major natural
    gas transportation corridors
  • 3. Deliverability into major natural gas end-use
    markets

69
Production Capabilities and the Ability To Move
Supplies Onto The Interstate Network
  • Identification of the major producing areas
  • Recent levels of development and production
  • Expansion possibilities
  • What interstate pipeline systems access the area?
  • What are their capabilities (capacity) to receive
    supplies?
  • Indications of capacity constraint?
  • Measures being taken (if any) to resolve the
    problem
  • To what degree are storage and support facilities
    integrated?

70
Transmission of Gas Along The Major Natural Gas
Transportation Corridors
  • Major corridors delineated (e.g. within the U.S.
    and Canada)
  • For each corridor
  • Major expansions and new pipelines since 1990?
  • Identify pipeline systems that ply the corridor
  • Current capabilities and utilization levels
  • Indications of service bottlenecks
  • Amount and type of underground storage serving
    shippers
  • Market centers/hubs and their role within the
    corridor
  • Expansion possibilities
  • For the network as a whole Overall
    capacities/usage growth.

71
Deliverability Into Major Natural GasEnd-use
Markets
  • Major market areas examined
  • For each market area
  • Major expansions and new pipelines
  • Identify pipeline systems that feed into the
    market
  • Current capabilities and utilization levels
  • Integration of underground and LNG storage
    deliverability
  • How end-use customer usage shifts have
    influenced expansions and utilization of
    available capacity
  • Expansion possibilities
