  1. Increasing Access to the GridNIPPCSeptember 8, 2005 Brian Silverstein VP, Operations and Planning Bonneville Power Administration

  2. Increasing Access to the Grid • Expand the Pie • Increase Utilization • Coordinated Planning

  3. 2001: Network Constraints

  4. Infrastructure Program • To address the region’s transmission needs, BPA developed a transmission infrastructure program in 2001 to focus on: • Maintaining reliable transmission service to population centers. • Restoring or enhancing transfer capability across key paths. • Providing margin so the system can be maintained. • Evaluating and investing in non-wires alternatives.

  5. Infrastructure Accomplishments • First major line construction in the Northwest since 1987. • Invested more than $1 billion over four years. • Two 500-kV lines completed, one under way. • Modernized the nation's largest direct current terminal (Celilo Converter - 3100 MW). • Several projects to upgrade local load service.

  6. Status of BPA Infrastructure Additions W a s h i n g t o n Grand Coulee-Bell 500 KV Transmission Line Project April 2003-Dec 2004 Completed Underway Substation Project Completed BPA Transmission Lines Indian Reservation On Hold Proposed Substation Project Completed Olympic Peninsula Reinforcement 1-5 Corridor Generation Addition Northern Idaho Reinforcement Kangley-Echo Lake 500 KV Transmission Line Project July 2003-Dec 2003 Schultz Series Capacitors March 2003-Nov 2004 Puget Sound Area 500/230 KV Transformer Schultz-Hanford Area SW Washington NW Oregon Reinforcement Raymond-Cos West of Mcnary West of Slatt M o n t a n a Portland Area Reinforcement 3 Celilo Modernization Winter 2001-June 2004 Pearl Transformer Project Dec 2002-Dec 2003 Albany Eugene Rebuild I d a h o O r e g o n Swan Valley Goshen Rebuild Anderson Ranch Mountain Home Rebuild Southwest Oregon Coast Reinforcement Lower Valley Reinforcement

  7. 2005: Network Constraints

  8. Non Wires Solutions • Potential Measures • Demand response • Energy efficiency • Distributed generation • Appropriately sited large generation • Objectives • Find least-cost solutions to transmission limitations • Provide equivalent reliability to a transmission fix • Benefits of transmission deferral • Time value of money • Option value of delaying costly investments

  9. Path Utilization Example

  10. Increase Utilization • Flow-based ATC methodology • Constraint Schedule Management • New products and services • Conditional firm • Redispatch • Better remarketing of unused rights • Strategic use of nonfirm and short-term firm

  11. Transmission Buying Strategy for Wind Peak Output Buy When Needed Sell When Not Needed Average Output

  12. Integrated Planning Concept • Objective: Achieve an adequate and least-cost plan in a functionally separated industry. • Premise: Most commitments to long-term transmission, particularly those that require expansion, are tied to utility power purchase agreements. • Concept: Establish a coordinated planning cycle that links individual utility resource planning with a region-wide transmission open season. • Benefits: • Improves our ability to develop transmission when needed. • Provides for a regional adequacy assessment.
