  2. Types of Renewable Resource Studies in 2008 • Individual Utility Studies • PNM’s 2008 Collector System Study • State Study Requirements • Colorado Senate Bill 100 • Nevada RETAAC Study • Arizona Corporation Commission BTA Renewable • Subregional Study • SWAT Renewable Transmission Taskforce 1/28/09 FERC / WestConnect Webinar

  3. 2008 Colorado SB 100 Study Tom Green, Public Service Company of Colorado 1/28/09 FERC / WestConnect Webinar

  4. 2. Colorado Senate Bill SB 07-100, codified at C.R.S. § 40-2-126 Senate Bill 100 Status2 • Dec 18, 2008 CPUC workshop on SB-100 plans to allow stakeholder input and feedback on priority. • Jan 12, 2009 CPUC workshop for stakeholder response • Feedback from CPUC on priority of CPCN’s on transmission plans • Future CPCN process for SB-100 projects 1/28/09 FERC / WestConnect Webinar

  5. SB-100 Transmission Plan 230kV 345kV Ault Zone 1 Pawnee Cherokee Missile Site Smoky Hill Daniels Park Zone 2 Lamar Comanche Zone 3 Zone 5 Zone 4 Calumet Vilas 1/28/09 FERC / WestConnect Webinar

  7. Renewable Energy Transmission in Nevada Brian Whalen Transmission Planning Manager WestConnect Planning Webinar with FERC January 28th, 2009

  8. WHY? RPS and NV Energy’sGreen Attitude 6 new projects (135 MW) in-service 2007-08 8 geothermal projects (~280 MW) under development 2 of the U.S.’s largest solar plants now in Southern Nevada Plan to add 200 to 400 MW of wind. Joint Ventures in place. Current portfolio consists of 36 projects totaling 586 MW 1,000 MW by end of 2012 8

  9. Solar Power Mojave Desert, centered in Southern CA and extending into Southern NV is the U.S. prime solar resource Nevada is a leader in solar power per capita Solar technologies improving Cost per kWh is relatively high but declining 9

  10. Local NV Energy Initiatives Public Utilities Commission of Nevada approved permitting of both 250 miles of 500 kV and 40 miles of 345 kV, plus siting studies for over 600 miles of new backbone transmission 10

  11. State / NV Energy Initiatives “RETAAC” Renewable Energy Transmission Access Advisory Committee Global resource mapping tool for NV developers Land use Exclusion area Resource areas Transmission Phase II Investigation of funding alternatives Merchant New State Agency Existing State Agencies Open season Recommendation of specific collector systems to pursue.

  12. RETAAC BLM & NVE queues 4 types of resources Trunk line development Multi- stakeholder Effort BLM NDOW Municipals IOU IPP State Agencies Environmental Groups 12

  13. Regional / Federal / NV Energy Initiatives • WestConnect/ SWAT renewablesstudies (presented by P. Krzykos) • Nevada Siting Issues • Significant Constrained Areas (environmental or government use) • > 80% of Nevada is controlled by Federal Government • Nevada has BLM, USFWS, DOE, DOD, BIA, DOI, … • Problems with any single agency can stop an entire project. • Potential Solutions • Draft DOE §386 Corridor Process • 1/3 of total in Nevada (2000 miles) • Federal master agreements

  15. PNM’s 2008 Collector System Study Tom Duane, Public Service Company of New Mexico 1/28/09 FERC / WestConnect Webinar

  16. Total Wind Guadalupe/Willard/Duran: 2450 MW Gladstone 1200 Stage 4 Continue transmission expansion into wind resource zones Complete wind collector system for up to 2400 MW Total Cost for Stages 0-4: ~$670M BA Guadalupe 650 200 Willard Belen 400 700 250 Duran 100 New 345 kV line Existing 345 kV line 150 Existing 115 kV line Ft. Craig New station Existing station Proposed wind project Existing or committed wind project VL Tap • Expand Willard, Duran and Guadalupe 345 kV stations • Build Duran – Guadalupe 345 kV (two lines) (55 mi) • Build Willard – Duran 345 kV (second line) (50 mi)

  17. Total Wind Guadalupe/Willard/Duran: > 4000 MW (?) Gladstone 1200 Stage 5+ Integration with High Plains Express BA >1000 200 Willard Belen 400 >1000 250 Duran 100 New 345 kV line Existing 345 kV line 150 Existing 115 kV line Ft. Craig New station Existing station Proposed wind project Existing or committed wind project VL Tap • Build HPX 500 kV lines (may not need two circuits from Guadalupe to Ft Craig) • Install 500/230 kV transformer at Gladstone • Install 500/345 kV transformer at Guadalupe • Install 500/345 kV transformer Ft Craig • Install 500/345 kV transformer at Duran

  18. SWAT Renewable Transmission Task Force Peter Kryzkos, Arizona Public Service 1/28/09 FERC / WestConnect Webinar

  19. Potential Resource Location

  20. SWAT Renewable Transmission Task Force 2009 Study Plan • Renewable potential in Arizona • Update queue • Interconnection queue has exceeded Arizona Renewable Energy Assessment results in some areas • Arizona solar queue is now ~12,000 MW • Utilize regional renewable data (NREL, etc.) • Update potential transmission circuits in Arizona • Refine conceptual corridors based on resources and development potential 1/28/09 FERC / WestConnect Webinar

  23. National Renewable Energy Laboratory (NREL) Concentrating Solar Power Prospects in Arizona Taken Directly from NREL website: http://www.nrel.gov/csp/images/1pct_csp_az.jpg 1/28/09 FERC / WestConnect Webinar

  24. Quality of Wind Resources In Arizona *Developed by DOE and NREL • At 50m elevation, Class 4 or higher is typically used for utility scale wind generation (NREL). • At 80m elevation, Class 3 areas could have higher wind power class because of possible wind shear (NREL) • Arizona has predominately Class 3 or lower wind resources Taken Directly from the United States Department of Energy website: http://www.eere.energy.gov/windandhydro/windpoweringamerica/maps_template.asp?stateab=az

  25. SWAT Renewable Transmission Task ForceRefining Solar Resource and Transmission Potential in ArizonaAs and Example + • Overlay SWAT RTTF conceptual transmission and injection points with solar resource data • Combine with information from interconnection queue of regional utilities Taken Directly from NREL website: http://www.nrel.gov/csp/images/1pct_csp_az.jpg

  26. 8835 MW 530 MW 845 MW 1510 MW Conceptual Refined Arizona Solar Resource Zones DRAFT 1/28/09 FERC / WestConnect Webinar

  27. SWAT Renewable Transmission Task ForceNext Steps • Refine renewable potential / locations • Analyze regional renewable resource data • Evaluate interconnection queue information • Refine injection points and transmission corridors • Conduct these efforts throughout SWAT footprint • Evaluate transmission plans for 20% (2018 case year) of total projected renewable generation built and potentially a 40% (2025 case year) scenario. • Technical Study 1/28/09 FERC / WestConnect Webinar
