Purpose of the Assessment
To assess the impacts of natural gas infrastructure enhancements on bulk electric system reliability
Develop an understanding of the relationships between infrastructure, supply and contracting
Support the ongoing training of ISO Staff
March 3, 2005 3
Findings
The existing market structure puts local gas distribution companies (LDCs) at a competitive advantage over electric power generators for the purchasing/financing of natural gas services, primarily due to the “pass-thru” of costs across customer rate base.
Recent natural gas infrastructure expansions in
the Northeast have either been narrowly focused to serve specific markets (NYC) or were designed to bring Sable Island gas supplies to market.
March 3, 2005 4
Findings (cont.)
Given the recent declines in Sable Island production (deliveries), New England’s electric power sector has received little or no benefit from recent gas infrastructure development
The completion of the HubLine/M&N Phase III projects simply moved the same (or declining) Sable Island gas supply from one delivery point on the gas grid to another (from Tennessee to Algonquin)
March 3, 2005 5
Findings (cont.)
The ISO should monitor Sable Island gas deliveries, and the impact their declines are having on existing pipeline transportation contracts held by electric power generators
Natural gas infrastructure projects being developed and constructed over the near term will be sized to meet only the incremental load growth of LDCs, while they await new supply development
March 3, 2005 6
Findings (cont.)
The electric power sector should not expect any meaningful benefits from gas infrastructure development over the next several years
While the natural gas industry and electric power generators have had an ongoing dialogue regarding new products and services, currently, the electric generators do not have the economic incentives or the financial wherewithal to support or contract for any enhanced pipeline service offerings
March 3, 2005 7
Findings (cont.)
LNG projects proposed along the existing pipeline route, initially developed for Sable Island gas deliveries, will bring the greatest benefits to the electric sector by backfeeding the natural gas grid and creating a good deal of residual capacity benefits
LNG projects proposed along the St. Lawrence
River will bring the least amount of benefits to the Northeast U.S. as a large share of that new gas supply will probably remain in eastern Canada
March 3, 2005 8
Findings (cont.)
The value of pipeline infrastructure (economic and physical) is directly proportional to the availability of gas supply being injected into that infrastructure
ISO should monitor the regulatory developments at FERC regarding heat content of LNG to determine if this will have an adverse impact on the operation of gas-fired electric generators in the region
March 3, 2005 9
Findings (cont.)
ISO should monitor the market drivers which lead to the development of both natural gas infrastructure development and new products and services

A Review of the Existing Natural Gas
Infrastructure in the Northeast
March 3, 2005 11
Recent Gas Infrastructure Builds and the Market Drivers Supporting Them
Eastchester (Iroquois) Market is ConEdison (LDC) and NYC generators Provides a much needed backfeed to ConEd distribution system
HubLine (Duke) Market comprised of Generators (61%), LDCs (29%) & Marketers (10%) Provides a new backfeed to a weak Algonquin lateral
M&N Phase III (Duke) No Market Provides a new feed into Algonquin (HubLine) for access to Sable Island
gas The I-8 Uprating (Duke)
No Market Enhances Algonquin’s ability to serve emerging markets beyond Fore
River The Distrigas Project (Duke)
Market is Distrigas supply Expands Distrigas’ access to expanding New England gas markets
March 3, 2005 12
Current Market Environment for Gas Infrastructure Development
Declines in Sable Island gas production Proliferation of LNG terminal proposals The collapse of spark-spreads The decline of the “Mega-Marketers” Well organized NIMBY(ism)
March 3, 2005 13
An Assessment of Current Gas Infrastructure Capabilities
Distrigas New 60 MDt/d of capacity added on the
Algonquin system on October 1, 2004 Iroquois
70 MDt/d of primary firm held by Marketers with access to southwest Connecticut
60 MDt/d of secondary firm sold annually FERC approval for a new 10,000 HP compressor
in Brookfield, CT
March 3, 2005 14
An Assessment of Current Infrastructure Capabilities (cont.)
Algonquin and Tennessee These older pipelines have little in the way of
excess capabilities and would require to have gas introduced into their systems in the market area (LNG) in order to create any incremental capability
Portland and Maritimes & Northeast (M&N) While these newer pipelines have some
incremental capacity capabilities, both are considered supply-constrained at this point and into the near future
March 3, 2005 15
Gas Infrastructure Proposals - Medium Term (2005-2008)
Algonquin BGLS Project (Providence LNG Expansion)
Adds 500 MDt/d of takeaway capacity from the proposed expansion of the existing Providence LNG plant
IslanderEast This project proposes to transport 260 MDt/d from central
Connecticut to Long Island by late 2005 Status of supply to fill this capacity is currently undetermined FERC approved but currently stalled by the State of Connecticut
Duke Energy Gas Transmission Open Season Service commencement dates between 2006 and 2009 Earlier service dates will be to serve near term LDC
requirements; later service dates will serve LNG supply proposals
March 3, 2005 16
Gas Infrastructure Proposals - Medium Term (2005-2008) (cont.)
Tennessee Tewksbury-Andover Lateral (June 2005)
5 mile lateral with 25 MDt/d of capacity Serving Wyeth Pharmaceuticals and Bay State Gas (LDC)
Northeast ConneXion–New England (November 2007) Open Season extended into early 2005 Volumes said to be approx 100 MDt/d targets LDC markets Increased long-haul capacity from Gulf of Mexico
Distrigas (November 2007) 7.6 miles of new pipeline Up to 75 MDt/d of incremental access to Tennessee’s markets
March 3, 2005 17
Gas Infrastructure Proposals -Long Term (2009 & Beyond)
LNG projects along the St. Lawrence River Rabaska – 0.5 Bcf/d Gros Cacuona – 0.5 Bcf/d Characteristics:
Majority of gas will remain in eastern Canada U.S. deliveries will be made primarily to Iroquois, with
the potential for some deliveries into Portland Local opposition has become an issue for Rabaska Gros Cocuona requires developing a substantial pipeline
lateral to reach the markets
March 3, 2005 18
Gas Infrastructure Proposals –Long Term (2009 & Beyond) (cont.)
LNG projects in the Canadian Maritimes Bears Head (Anadarko) – 1.0 Bcf/d Canaport (Irving Oil) – 1.0 Bcf/d Characteristics:
Provides greatest benefit to the northeast infrastructure Majority of required infrastructure to access New England’s
gas markets is already in place (M&N pipeline) These projects are the furthest along in development
March 3, 2005 19
Gas Infrastructure Proposals –Long Term (2009 & Beyond) (cont.)
LNG projects in the Northeast U.S. Providence (RI) LNG (BLGS) – 375 MDt/d Weavers Cove (RI) – 800 MDt/d NorthEast Gateway (Offshore) – 800 MDt/d Broadwater (LI Sound)– 1.0 Bcf/d Characteristics:
All have significant NIMBY issues With the exception of NorthEast Gateway, additional
infrastructure will be required on pipeline mainlines
March 3, 2005 20
Products and Services
Past Impediments Offering new services without new capabilities Concentrating on the traditional gas marketplace
and not the emerging electric marketplace Charging customers for what they already get for
free Lack of market signals
Note: With the addition of significant supplies from the north (either LNG and/or increased Sable Island production), New England’s pipelines will be in a much better position to offer enhanced services
March 3, 2005 21
The Interdependency of Supply and Infrastructure
The value of pipeline capacity is directly driven by the availability of an adequate supply of gas
The location of incremental supplies will determine where infrastructure is built and what resultant benefit it will provide to the electric generation industry
Forecast future supply additions are currently influencing today’s pipeline capacity purchasing
decisions
