  3. Winter Cold Snap Summary Generation Outages in MWs

  4. ISO Actions to Protect New England • Ordered offline generation and transmission back in service • Requested voluntary conservation from public • Coordinated with North American Electric Reliability Council (NERC) and Northeast Power Coordinating Council (NPCC) • Arranged for additional imports from adjacent Control Areas • Issued alert of impending capacity deficiency followed by emergency procedures to balance supply and demand • Requested manning of substations as precautionary measure, based on lessons learned from August 14th blackout • Kept regulators and public informed of system conditions

  5. Cold Snap Report Key Findings • Electricity and gas markets performed reasonably well • Availability of gas for non-firm generation customers affected gas unit availability: • Dual-fuel units had much better availability than gas-only units • No evidence of anti-competitive behavior • No evidence that economic outages approved by ISO-NE exacerbated reliability issues or resulted in increased electricity clearing prices • Supply offers for gas-fired units were affected by timing inflexibility of electric market • Electricity markets provided only weak incentives for units, especially gas units, to be available during the Cold Snap

  6. Cold Snap Task Force • Formed at March 19, 2004 FDWG-EGWI meeting • Three meetings held to date: • April 5 • April 15 • April 29 • Broad Stakeholder Representation • ISO-NE • NEPOOL Members • Natural Gas Industry • Various NE State Agencies

  7. Cold Snap Task Force • Several straw proposals presented to begin addressing the market timeline issues and associated system reliability concerns • Cold Snap Working Group formed to deal with possible market changes to be implemented for winter 2004/2005 • Possible Alternative: Move up the “Market Process” by 12 (?) hours – Straw Proposal #1

  8. Next steps • Schedule next working group meeting(s) • Continue development of market timeline straw proposal, including market impacts • Detail all technical impediments to be resolved • Develop trigger mechanisms • Develop communication plan • Prepare for Cold Snap Task Force and NEPOOL Markets Committee in June

  9. ISO-NE Priority Items for Winter 2004/2005 • Formalize interaction between ISO Operations and Natural Gas pipeline operations • Communication protocols • Sharing of operational information • Notification of major events • Address market timeline issues under “event driven” conditions • Maximize use of existing dual fuel capabilities • Verify existing capabilities • Document facility specific operating issues • Address permit limitations
