2. 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)

3. Project Overview

4. 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

5. SWPG and MMR SWPG is… SWPG’s owner, MMR, 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

6. 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. R )
SunZia will deliver power generated by renewable resources to Western markets

7. 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

8. 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
