  1. Status Report on 2007–2016 Long-Term Reliability Assessment Mark Lauby August 16, 2007

  2. 2007 LTRA Schedule • Drafting LTRA • Open Meeting • Goals: • Increased Transparency • Identify Enhancements • Finalize Draft • PC Review • Board Approval • Release • Ongoing • August 16 • August 31 • Sept. 11-12 • Mid-October • October 15

  3. 2007 LTRA Emerging Issues

  5. General Observations • Difficulty evaluating resource adequacy, especially in organized markets • Reluctance to commit to long-term resource plans • Difficulty judging impact/effectiveness of renewables and demand-side programs • Dependence on gas still high; interruptible transportation contracts a big issue • More transmission projects announced, but concerns whether they will be built

  6. Specific Observations • Margins tight in: • New England • MRO-US • ERCOT • A significant increase in wind farms, • Only 1,800 MW in 2007-2016 peak generation • The remainder is considered energy-only • 11,621 MW of new nuclear power capacity: • ERCOT (6,176 MW) • FRCC (1,125 MW) • SERC (4,320MW) • WECC – RMPA • WECC – CA-MX • WECC – AZ-NM-SNV

  7. Key Observations • The U.S. DOE has identified two draft National Interest Electric Transmission Corridors (NIETC) • Some States have expressed objections • More Transmission Projects proposed (2007–2011) • Transmission/ancillary services to accommodate wind energy • Investments in Connecticut improving reliability

  8. Key Findings & Conclusions • Continued Dependency on Natural Gas in New England, Florida & California • Bulk Power System Expansion Plan Uncertainty makes Long-Term Reliability Assessment Opaque • Grid Investment Needed to Integrate Intermittent Resources • Regulatory Action impact Reliability Projects

  9. High-Level Scenarios Reliability Impacts of … • Significant penetration of wind energy • High integration of demand response • Natural gas unavailability due to supply or delivery limitations • Possible reductions in capacity as a result of emissions restrictions

  10. Questions and Suggestions • Any issues or concerns not being addressed? • Additional scenarios to be considered? • Other suggestions?
