Cold Snap Task Force
14
Cold Snap Task Force
Three high-priority, short-term objectives targeted for implementation prior to winter 2004/2005:
1) Electric Market Synchronization with Gas Market• ISO & NEPOOL Cold Snap Task Force (CSTF) –
Finalizing proposal with NEPOOL MC2) Electric/Gas Operating Committee
• Education, Understanding, Coordination, Communications
3) Investigate True Dual Fuel Capability & Promote Expansion
• EES Group – Environmental Consultants
15
1) Electric Market Synchronization with Gas Market– Cold Snap Proposal is event driven, triggered by
extreme weather and a potential for capacity shortages.
– Two options being decided upon by NEPOOL MC
2)Electric/Gas Operating Committee:- Coordination within four areas:
• Maintenance: scheduled & unscheduled• Operations: contingencies, blackout/system
restoration• Training: common-mode & emergency drills• Planning: contingency identification & analysis
Cold Snap Task Force, Con’t.
16
3) Investigate True Dual Fuel Capability & Promote Expansion
– ESS Group = Environmental Consultants• Compilation of environmental permits• Assess dual fuel constraints & limitations• Expansion strategies & feasibility analysis• Dialogue with New England Air Regulators• Site visits will determine real barriers
4) Other ISO Activities:– Access to pipelines EBBs: OFO & nomination confirmation– New England specific natural gas supply study
Cold Snap Task Force, Con’t.
17
• Timeline– Define problem & key issues - Complete– Publish Interim ISO-NE Cold Snap Report -
Complete– Prioritize issues & brainstorm solution sets -
Complete– Present proposal options to stakeholders - September – Finalize proposal & Market Rule &
procedures changes - September– Publish Final ISO-NE Cold Snap Report - September– Implement & test changes - Fall 2004
Cold Snap Task Force, Con’t.

3. De-listed ICAP quantities are only known with certainty in the current month. This number is adjusted when a delisted generator is out on maintenance to avoid double counting.4. Net Capacity = (SCC) + (Interchange) + (New Generation) - (De-listed ICAP Resources). In this equation, the SCC, Interchange and De-listed ICAP values are rounded to the nearest ten
and New Generation is rounded to the nearest hundred.5. Peak Load Exposure reflects values published in the April 2004 CELT Report. 6. Operating Reserve Requirement based on the first contingency (Generator at 1160 MW) plus 1/2 the second contingency (Generator at 1155 MW).7. Allowance for Unplanned Outages includes: forced outages and maintenance outages scheduled less than 14 days in advance.8. Assumed values based on ISO-NE study. 9. Relief from certain OP 4 Actions varies, depending on system conditions.
This analysis is a tabulation of weekly assessments shown in one single table. The information shows the operable capacity situation under assumed conditions for each week. It is not expected that the system peak will occur every week during June, July and August.

Notes: Please note that the information contained within the Capacity Analysis is a deterministic projection of system conditions which could materialize during any given week of the year.1. Installed Capability per September 1, 2004 SCC Report, less recent retirements or deactivations that have not yet been reflected in the SCC Report. The Operable Capability does not reflect possible
transmission constraints within the NEPOOL system.2. New Generation information includes 1) generation recently commercial but not yet reflected in the NEPOOL SCC Report totals used in the Installed Capability Column, and 2) future generation
as assumed by ISO-NE Planning Department. This value is rounded to the nearest hundred.3. De-listed ICAP quantities are only known with certainty in the current month. This number is adjusted when a delisted generator is out on maintenance to avoid double counting.4. Net Capacity = (SCC) + (Interchange) + (New Generation) - (De-listed ICAP Resources). In this equation, the SCC, Interchange and De-listed ICAP values are rounded to the nearest ten
and New Generation is rounded to the nearest hundred.5. Peak Load Exposure reflects values published in the April 2004 CELT Report. 6. Operating Reserve Requirement based on the first contingency (Generator at 1160 MW) plus 1/2 the second contingency (Generator at 1155 MW).7. Allowance for Unplanned Outages includes: forced outages and maintenance outages scheduled less than 14 days in advance.8. Assumed values based on ISO-NE study.9. Relief from certain OP 4 Actions varies, depending on system conditions.
This analysis is a tabulation of weekly assessments shown in one single table. The information shows the operable capacity situation under assumed conditions for each week. It is not expected that the system peak will occur every week during June, July and August.

Notes: Please note that the information contained within the Capacity Analysis is a deterministic projection of system conditions which could materialize during any given week of the year.1. Installed Capability per September 1, 2004 SCC Report, less recent retirements or deactivations that have not yet been reflected in the SCC Report. The Operable Capability does not reflect possible
transmission constraints within the NEPOOL system.2. New Generation information includes 1) generation recently commercial but not yet reflected in the NEPOOL SCC Report totals used in the Installed Capability Column, and 2) future generation
as assumed by ISO-NE Planning Department. This value is rounded to the nearest hundred.3. De-listed ICAP quantities are only known with certainty in the current month. This number is adjusted when a delisted generator is out on maintenance to avoid double counting.4. Net Capacity = (SCC) + (Interchange) + (New Generation) - (De-listed ICAP Resources). In this equation, the SCC, Interchange and De-listed ICAP values are rounded to the nearest ten
and New Generation is rounded to the nearest hundred.5. Peak Load Exposure reflects values published in the April 2004 CELT Report. 6. Operating Reserve Requirement based on the first contingency (Generator at 1160 MW) plus 1/2 the second contingency (Generator at 1155 MW).7. Allowance for Unplanned Outages includes: forced outages and maintenance outages scheduled less than 14 days in advance.8. Assumed values based on ISO-NE study.9. Relief from certain OP 4 Actions varies, depending on system conditions.
This analysis is a tabulation of weekly assessments shown in one single table. The information shows the operable capacity situation under assumed conditions for each week. It is not expected that the system peak will occur every week during June, July and August.
