Where we are, and where we are going…. 25% 33% 50% 3

Vision to 2030 SB 350, De León Increases the 33% RPS to 50% RPS Paves the way for transformation of the California ISO into a regional organization Requires integrated resource plans Requires a study on low-income customers access and barriers to clean technologies 4

Vision to 2020 Electricity sector is about 20% below 1990 GHG emission levels From 2008 to 2013: – Renewable capacity almost doubled – Coal generation reduced by more than half – GHG emissions reduced by a quarter 5

California Coal Use Includes Imports

California’s Transmission Planning for Renewable Energy: RETI and RETI 2.0

29 The Renewable Energy Transmission Initiative (RETI 1.0) Initiated June 2007 Ease designation of future transmission line corridors Identify transmission projects Expedite siting and permitting - transmission line and renewable generation 30 Competitive Renewable Energy Zones (CREZs) 80,000 MW potential statewide ~66,000 MW in California’s Mojave and Colorado Deserts.

30 RETI 1.0 Process Phase 1 – Identification of CREZs Phase 2 – Refinement of CREZs Phase 3 – Work on priority CREZs Stakeholder Participation, including: Transmission Owners/Providers Renewable Energy Developers Electric Retail Providers Federal, State, and Local Government Agencies Native American Tribal Governments Landowners Environmental and public interest organizations Balancing Authorities and Utility Regulatory Commissions Other interested parties

31 RETI 1.0 Output Informed… Renewable procurement and transmission permitting at the CPUC Renewable generation and transmission planning decisions at the POUs Renewable permitting and transmission corridor designation at the CEC Transmission planning process at the CAISO Transmission planning for the DRECP
