Renewable Energy Transmission Planning Process Keith Casey Vice President, Market & Infrastructure Development Southwest Renewable Energy Conference May 21, 2010
CAISO New Transmission Planning Process • ISO Board of Governors approved Revised Transmission Planning Process (RTPP) on May 18, 2010 • State-wide planning approach • New criterion for “policy-driven” transmission (e.g., 33% RPS) • Whole system planning instead of single-project approach • FERC Order 890 compliance • Final proposal addresses the following • Opportunities for independents to build transmission • ISO decides when competing proposals apply to different siting authorities • Expedient processing of generation interconnection agreements • FERC filing planned for June 1, 2010
1/1/10 3/31/10 12/31/10 3/31/11 • 2010/2011 cycle – • Phase 1 • ISO unified planning assumptions & study plan • Regional & sub-regional collaboration 2010/2011 cycle – Phase 2 April 2010 – March 2011 Comprehensive Planning for ISO Balancing Authority Area • 2010/2011 cycle – • Phase 3 • ISO receives and evaluates proposals to build designated plan elements Renewable Access Plan for ISO Area 2010/2011 Comprehensive ISO Transmission Plan 2011/2012 cycle – Phase 1 January – March 2011 2011/2012 cycle – Phase 2 April 2011 – March 2012 CAISO Transmission Planning Process • Proposal will create an annual three-phase planning process Slide 3
