  1. Transmission Needs for 33% RPSBarry Flynn May 16, 2012

  2. Introduction Overview of importance of transmission costs Enough transmission approved to reach 33% RPS goal Deliverability upgrades - one major driver of new transmission

  3. Transmission Costs Are On Pace to Increase Significantly Over the Next 10 Years Represents 10-15% increase in electric bills

  4. Approval Status of Key New Renewable Transmission Facilities $5.5 B (Renewable w Permit shown in slide 3) $2.1 B (Renewable w/o Permit shown in slide 3)

  5. Renewable Capacity in CAISO’s Generator Interconnection Queue versus Need for 33% RPS Source: CAISO Board of Governors Briefing Memo, May 9, 2012

  6. Illustrative Annual Wind Generation Profile

  7. Contracting Capacity from 3P/Market is Significantly Less Costly than Building DNUs

  8. Concluding Remarks Transmission costs are becoming a major component of total electric supply costs. The current process will probably lead to building transmission beyond that needed to meet 33% goals. The CAISO has excessively stringent criteria to determine renewable resource deliverability. The State needs to find more cost effective ways to meet Resource Adequacy goals.
