Current SB-100 Transmission Plan10-22-2009 New Ault-Cherokee 230 kV ~ISD 2015-2016 New Pawnee-Smoky Hill 345 kV, ISD 2013 New Pawnee-Daniels Park 345 kV -2nd circuit ~ISD 2016-2017 New Missile Site 230 kV (ISD 2010) & 345 kV (ISD 2013) New Midway-Waterton 345 kV ISD 2011 New Lamar-Comanche 345 kV & Lamar - Missile Site 345 kV ~ISD 2016-2017 New San Luis Valley-Calumet-Comanche 230 & 345 kV lines ~ ISD 2013 New Lamar –Vilas 345kV ~ISD 2016-2017

  7. High Plains Express Initiative • Two 1,280 mile, 500kV, AC lines through WY, CO, NM and AZ • 3,500 – 4,000 MW of transmission capacity • Connects Regional Projects • 11 parties participating • Under second phase feasibility studies

  8. Completion of HPX Initiative • Increased local generation • Inclusion of new renewable generation plants • Reduced carbon footprint in the local community • Cost of energy favors export of local generation • Inability to utilize all local generation • Sell generation on the wholesale market to New Mexico and Arizona
