  1. Wyoming’s Renewable Energy Resources and the TransWest Express Project National Grid: The West’s Renewable Energy Future Joint CCPG-SWAT-SIERRA Meeting August 20, 2008

  2. The West’s Renewable Energy Future -Contribute to the current debate on the West’s renewable energy future • Renewable Energy Drivers • Population & Demand Growth • Renewable Portfolio Standards • Greenhouse Gas • Report Findings • Wind and solar are two most-viable renewable energy options • Long distance transmission lines from Wyoming can be justified by Desert SouthWest’s demand and Wyoming’s high quality wind resources • Report is available at http://www.nationalgridus.com/

  3. Wyoming’s Wind Potential - Non-solar Renewable Energy potential

  4. Wyoming’s Wind Potential - Compared to Thermal Solar potential

  5. Delivered Energy Cost Estimate of Alternatives

  6. Summary and Conclusions • Need for renewable energy supplies in the DSW is especially acute • Regional, state, and possible federal legislation have created a demand between 58,000 and 115,000 GWh for the DSW region • The West is blessed with adequate renewable energy sources to meet this energy gap specifically wind and solar energy • The most significant barrier to developing wind resources is lack of transmission • The best quality Wyoming wind can be delivered at lower costs than California wind, lower costs than local CSP, and at costs competitive with natural gas fired generation

  7. TransWest Express 3,000 MW 500kV bi-pole HVDC 900 miles from SE WY to Marketplace Hub in NV 2013- 15 in-service date CAPEX $3.08 B Levelized delivery cost (2008$) $15/MWh (100% LF) $29/MWh (51% LF) Focused on regional needs TransWest Express Project- Project summary

  8. TransWest Express Project • Anschutz Corporation acquired the rights to TWE in July 2008. • Denver-based Anschutz has been actively involved in energy development projects in Wyoming and through the West. • National Grid, which has led development for last two years, is withdrawing from the project. • Arizona Public Service, who first created the project in 2005, will continue to participate in the project and may have a future equity position.

  9. Thank you
