1 WGA West-wide Renewable Energy Zone (WREZ) Project

2 Origin of Proposal 6/06 WGA Clean and Diversified Energy Initiative recommendations 6/06 WGA Clean and Diversified Energy Initiative recommendations 9/07 WGA/NWCC/GEA renewables and transmission summit in Ft. Collins recommendation to identify WREZs the incorporate all renewable fuels (solar, geothermal, wind, biomass, hydro, hydrokenetic, etc. 9/07 WGA/NWCC/GEA renewables and transmission summit in Ft. Collins recommendation to identify WREZs the incorporate all renewable fuels (solar, geothermal, wind, biomass, hydro, hydrokenetic, etc. Brainstorming group to explore how Ft. Collins recommendation could be implemented Brainstorming group to explore how Ft. Collins recommendation could be implemented 10/07 WREZ briefing paper 10/07 WREZ briefing paper 11/07 presentations to and sign-off from WGA Staff Council, WIEB Board, CREPC 11/07 presentations to and sign-off from WGA Staff Council, WIEB Board, CREPC 12/07 Governors proposal to Secretary Bodman for a WREZ project 12/07 Governors proposal to Secretary Bodman for a WREZ project 3/12/07 Meeting of states, DOE, FERC staff, WECC staff 3/12/07 Meeting of states, DOE, FERC staff, WECC staff

3 State Actions Affecting Renewables 8 states with RPS + 8 states with RPS + renewable policies in BC and AB 7 Governors, 1 Premier working on region carbon cap and trade system (which will increase pressure for more renewable development) 7 Governors, 1 Premier working on region carbon cap and trade system (which will increase pressure for more renewable development) State-by-state REZ efforts State-by-state REZ efforts Texas CREZ Texas CREZ CO S 91 CO S 91 CA Renewable Energy Transmission Initiative CA Renewable Energy Transmission Initiative AZ Black & Vetch study AZ Black & Vetch study NV Governors renewable and transmission task force NV Governors renewable and transmission task force Other Other State-only work misses regional opportunities and could balkanize the renewable energy market State-only work misses regional opportunities and could balkanize the renewable energy market Existing CO2 power purchase or power plant siting limitations

4 Overview of WREZ Phases 1. Identification of WREZs Technical analysisTechnical analysis Stakeholder ground truthingStakeholder ground truthing 2. Conceptual transmission from WREZs 3. Coordinated procurement for renewables (beyond current budget period) 4. Institutional options to facilitate interstate transmission for renewables (beyond current budget period)

5 Critical Elements in Phase 1 (identification of zones) Technical work Technical work Technology characterization; resource assessment; supply curves; delineation of WREZ boundaries Technology characterization; resource assessment; supply curves; delineation of WREZ boundaries Transparency/communication: Maximum stakeholder input to identifying WREZs Transparency/communication: Maximum stakeholder input to identifying WREZs Web based GIS Web based GIS Easy electronic stakeholder input Easy electronic stakeholder input Iterations between technical work (e.g., B&V type work, stakeholder input, and WREZ technical committee/work groups) Iterations between technical work (e.g., B&V type work, stakeholder input, and WREZ technical committee/work groups) Build on/supplement individual state REZ work Build on/supplement individual state REZ work

6 Critical Elements in Phase 2 (conceptual transmission from zones) LSE fuel choice is prime determinant LSE fuel choice is prime determinant After identification of REZs, LSE (and states/provinces) need tools to: After identification of REZs, LSE (and states/provinces) need tools to: Prioritize REZ options Prioritize REZ options Compare with other options Compare with other options Identify synergies with other LSEs Identify synergies with other LSEs Integrate with existing sub-regional and WECC transmission expansion planning processes Integrate with existing sub-regional and WECC transmission expansion planning processes

7 Phase 2: Pushing and Pulling on the Transmission Expansion String New Approach: Expanding options LSEs consider User-friendly model to: Enable LSEs and others to evaluate REZ options from their perspective Compare with other generating options Identify synergies among LSEs to reach specific zones Historical Approach: Push on the string by: Transmission planners evaluating lines to renewable resource areas (e.g., exercise Order 890 transmission planning protocols); Increasing rate of return on transmission investments Designating corridors and pre-empting state siting law

8 Thinking on REZ Structure Steering Committee Advisory Committee Technical Committee Workgroup

9 Tentative (speculative) Schedule Kick-off meeting in May Kick-off meeting in May Governors explain project Governors explain project Solicit participation Solicit participation Followed immediately by meeting of Technical Committee and formation of Work Groups Followed immediately by meeting of Technical Committee and formation of Work Groups Complete WREZ identification in November(?) and officially launch Phase 2 (conceptual transmission from WREZs) Complete WREZ identification in November(?) and officially launch Phase 2 (conceptual transmission from WREZs)

10 Relationship with WECC/Sub- Regional Planning (SPG) Work WREZ identification too late for 2008 TEPPC study cycle, but timely for 2009 study cycle WREZ identification too late for 2008 TEPPC study cycle, but timely for 2009 study cycle Much better wind and solar data being developed by NREL which will be used in WREZ project and should be used in TEPPC Much better wind and solar data being developed by NREL which will be used in WREZ project and should be used in TEPPC 2 km grid, 100 meter hub height, 10 minute wind data 2 km grid, 100 meter hub height, 10 minute wind data 10 km grid solar data 10 km grid solar data Need TEPPC and Sub-Regional Planning Group participation in Implementation of Phase 2 Need TEPPC and Sub-Regional Planning Group participation in Implementation of Phase 2 Development of model to evaluate WREZs from LSE resource planner perspective Development of model to evaluate WREZs from LSE resource planner perspective Incorporation of WREZ info into TEPPC data base Incorporation of WREZ info into TEPPC data base Participation in Work Groups and Technical Committee Participation in Work Groups and Technical Committee
