Status Report on Electric Renewable Resource Procurement and Renewable Portfolio Standard; Update on Senate Bill X1-2 Board of Public Utilities October 21, 2011
Background 2002: Senate Bill 1078 requiring 20% of retail sales from renewable energy by 2017. 2003: Riverside becomes first California municipal utility to adopt an RPS; 15% by 2010 and 20% by 2015. 2006: Senate Bill 107 accelerates date for reaching 20% to 2010. 2007: Riverside adopts revised RPS; 20% by 2010, 25% by 2015, and 33% by 2020. 2008: Governor Schwarzenegger issues Executive Order requiring IOUs to reach 33% by 2020. 2010: RPU serves 20.7% of its retail load with renewable energy (including large hydro from Hoover Dam). 2011: Senate Bill X1-2 passed, applying 33% by 2020 requirement to all utilities including POUs; disallows Hoover. 1

California Renewable Energy Resources Act (SBX1-2) Procurement Requirements
SBX1-2 Procurement Requirements Signed by the Governor April 2011 Defines qualified renewable energy resources: Solar, geothermal, wind, biomass, landfill gas, small hydro (< 30 MW) Does not include large hydro (> 30 MW) Establishes minimum renewable energy requirements during three compliance periods: Period 1: Average of 20 percent of retail load during 2011- 2013 Period 2: 25 percent by December 31, 2016 Period 3: 33 percent by December 31, 2020 State requirements now exceed City’s RPS 10
SBX1-2 Procurement Requirements Three portfolio categories: Category 1: First point of interconnection in California Category 2: Firmed and shaped energy scheduled into California Category 3: Unbundled renewable energy credits (RECs) and other eligible renewable energy products that do not qualify within Category 1 or 2 11
SBX1-2 Procurement Requirements Sets renewable energy requirements for each compliance period: Period 1: At least 50% from Category 1; no more than 25% from Category 3 Compliance Period 2: At least 65% from Category 1; no more than 15% from Category 3 Compliance Period 3: At least 75% from Category 1; no more than 10% from Category 3 Renewable resource contracts executed before June 1, 2010 count in full toward meeting the requirements 12

Current Activities to Procure New Renewable Resources
Long-Term Procurement Activities Participate in renewables requests for proposals (RFPs) issued by the Southern California Public Power Authority (SCPPA). SCPPA RFP for long-term renewable resources Proposals were due January 31, 2011 Over 200 proposals were received Included in-state and out-of-state renewables First-year prices for best in-state resources $85/MWh – $117/MWh Biogas proposals are subject to regulatory uncertainty Three other proposals remain under consideration by several SCPPA members 17
Long-Term Procurement Activities Meet directly with renewable resource developers Allows RPU to consider opportunities that become available during intervals between SCPPA RFPs Enables development of customized transactions Creates possibility for opportunistic procurements Provides access to market intelligence 18
Long-Term Procurement Activities Preparing to issue RFQ/RFP for development of photovoltaic project at Tequesquite Landfill 8- 10 MW capacity would produce about 0.7% of RPU’s retail load Meets content requirements for Category 1 Would come on-line by 2013, if competitive 19
Short-Term Procurement Activities Resources conducted a short-term RFP in August 2011 Short-term purchases of renewable energy products to help meet RPS requirements during Compliance Period 1 Six responses; three chosen: 20 GWh firmed and shaped wind (Category 2) – Iberdrola 20 GWh firmed and shaped wind (Category 2) – Powerex 30 GWh renewable energy credits (Category 3) – Idaho Power Incremental cost of ‘green’ attributes about $500,000 20
Market Challenges for Procuring Renewable Resources
Market Challenges for Renewable Resources Governor’s plan calls for development of 12,000 MW of distributed renewable resources Proposed in-state renewable interconnection requests at the ISO exceed 52,000 MW: 36,000 MW solar 16,000 MW wind 350 MW geothermal 90 MW biomass “30% of long -term RPS contracts (10 years or more) approved by the CPUC have been cancelled.” – August CEC report 22
Renewables Market Many renewable developers unable to obtain financing Project development risks Lack of capital sources RPU renewable projects that have not materialized Wintec Phase 2 Shoshone La Paz Other SCPPA utilities also subject to project failures/risks Shoshone (Anaheim) La Paz (Anaheim, Azusa, Burbank, Glendale, Pasadena) Raser – developer bankruptcy (Anaheim, Burbank, Glendale, LADWP, Pasadena) Biogas – regulatory uncertainty (Anaheim, Burbank, Glendale, LADWP, Pasadena) 23

Regulatory Rulemaking for SBX1-2 Implementation
Regulatory Rulemaking Processes California Public Utilities Commission (CPUC) Rulemaking Rules for IOUs May create significant precedents for publicly-owned utilities Started in June; will continue into 2012 California Energy Commission (CEC) Rulemaking Rules for publicly owned utilities Started in June; will continue through June 2012 CEC issued concept paper August 22, 2011 Impacts local control Addressing through CMUA 28
Compliance Requirements for Publicly Owned Utilities Under SBX1-2
Enforcement Program SBX1-2 requires local governing board of each POU to adopt an enforcement program by January 1, 2012 Measures that the local governing board may adopt include: Cost limitations for procurement expenditures Conditions to allow delaying compliance (e.g., circumstances that delay development or delivery of renewables) Rules to apply excess procurement from one compliance period to subsequent compliance periods POU must take all necessary action to achieve compliance Adoption of RPU’s enforcement program Consideration by Utility Board: November 18, 2011 Consideration by City Council: December 6, 2011 30
