  1. SunZia Project Description • Proposed 500kV transmission line with strategic interconnections for export to Western markets • The SunZia transmission route will connect New Mexico with Arizona: ~ 350 miles • Right-of-way applied for will permit up to two, 500kV (AC) lines • Ultimate transfer capacity: 3,000 megawatts (MW)

  2. Project Overview

  3. SunZia Participants • Project owner is SunZia Southwest, LLC (a Delaware LLC) • Entities negotiating the SunZia Memorandum of Agreement (MOA) include: • Utility companies • Private development companies (like SWPG) • Financial investors • Target date to execute MOA: January 1, 2008

  4. SWPG and MMR • SWPG is… • a privately owned project development firm, based in Phoenix, active in the Southwest since 1999 • a developer of generation facilities, including 2,360 MW Panda Gila River Project; 1,000 MW Bowie Power Station • a WECC member • SWPG’s owner, MMR, is… • a privately owned construction services firm, based in Baton Rouge, LA, with annual sales of $300 million • experienced in the development and construction of power generation facilities of over 20,000 MW in 31 states and 4 continents

  5. Interstate Transmission • RETA coordinates with Regional Transmission Initiatives to “…plan…and negotiate with entities within and outside the state for the establishment of interstate transmission corridors.” • Arizona Renewable Energy Standard of 2006: Regulated electric utilities must provide 15% of total megawatts sold from renewable resources by 2025 (RES Rules: A.A.C. R14-2-1801) • SunZia will deliver power generated by renewable resources to Western markets

  6. Project Activities • Conducted feasibility studies • Studied power-flow interconnections/potential impacts • Product of past Southwest Area Transmission (SWAT) planning • Performed preliminary route screening • Developed regulatory support • Conducted Open Season for participation • Initiated WECC project rating process

  7. Project Activities • Continued meetings with… • Governor Richardson’s staff, Public Regulation Commission, EMNRD, and NM Congressional delegation • Governor Napolitano’s staff, Corporation Commission, Chair of Transmission Line Siting Committee, and AZ Congressional delegation • SWAT and Federal Energy Regulatory Commission • Bureau of Land Management – NM and AZ

  8. Preliminary Route Screening • Identified potential collector points for wind and solar energy resources • Identified study area/corridor primarily in southwestern NM and southeastern AZ • Inventoried regional environmental resources • Identified potential transmission line routes

  9. Access to Renewables

  10. Project Schedule • Estimated Project Completion Dates: • Phase 0 – Development Agreement • Initiate 06/2006 • Complete 12/2007 • Phase 1 – Siting and Permitting • Initiate 01/2008 • Complete 12/2011 • Phase 2 – Design and Construction • Initiate 07/2009 • Complete 12/2012

  11. Milestones • Initiated Development Agreement – March 2007 • Established project company: SunZia Southwest, LLC and project management roles • Developed budget and schedule • Drafted Memorandum of Agreement (MOA) • Execute Development Agreement – January 2008 • Initiate NEPA/Scoping Process – January 2008 • Obtain Record of Decision, Right-of-Way Permits, and other permits – December 2011 • In-service – December 2012

  12. Opportunities for New Mexico • Provides access to Western markets for renewables • Provides points of connection for future RETA-supported collector transmission systems • Improves reliability and power transfer throughout the Western Interconnect
