National Wind Coordinating Committee Planning Meeting June 3

National Wind Coordinating Committee Planning Meeting June 3 -4, 2003 Portland, Oregon Dean Perry Chair - SSG-WI Planning WG 1

Overview • Overview of SSG-WI Planning work • How it is related to NWCC Draft Transmission Planning Principles Paper 2

What is SSG-WI? • A seams coordination forum sponsored by the 3 proposed RTOs in the West (Principle 8. ) • Steering Group and WGs are open, everyone is ENCOURAGED to participate • SSG-WI PWG – Those now involved include state agency representatives, resource developers (wind and coal), marketers, IOUs, public utilities (Principle 2. ) • RTOs make final decisions and implement 3

SSG-WI Planning Function • SSG-WI does transmission Planning (identifies needs, runs studies, identifies solutions)- - conceptual ideas, pre- to early- WECC process (Principle 3. ) • Doing “congestion relief” planning (to expand current capability), not “reliability” planning (to maintain current capability). Utilize reliability planning of individual entities as input. (Principle 7) • Focus is on forecasting future uneconomic congestion and developing alternative solutions (transmission and non-transmission) • Looking West-wide, not Subregional (Principle 1. ) • Analyze historical congestion – Report on SSG-WI Web Site 5

SSG-WI Planning Function • SSG-WI supports WECC project review procedures and WECC reliability criteria and standards • SSG-WI does not sponsor projects or implement projects • SSG-WI will support state siting and permitting processes as requested • Plan to issue Annual Transmission Reports – First report scheduled for release in September 2003 6

2003 Planning Study • 2008 – – based upon resources to be on line by Jan 2004 plus others on-line during 2004 – hydro and gas price sensitivities – Transmission energized by 2008 – Identify potential areas of transmission congestion • 2013 – – looking at 3 resource scenarios: coal, renewable, and gas (Principle 4) – hydro and gas price sensitivities – Identify areas of congestion & evaluate alternative solutions 7
