California Renewables Portfolio Standard Implementation

This document discusses the implementation of the California Renewables Portfolio Standard by the Senate Energy, Utilities, and Communications Committee. It provides an overview of Southern California Edison's (SCE) leadership in renewable procurement, their commitment to buying solar energy, and their efforts in transmission development. The document also highlights the changes in renewable procurement since 2002 and the eligible renewable procurement activity. It concludes with regulatory and legislative actions required to support the state's renewable energy goals.

  1. Implementation of the California Renewables Portfolio Standard Senate Energy, Utilities, and Communications CommitteeHon. Christine Kehoe, Chair February 6, 2007 Stuart R. HemphillDirector of Renewable & Alternative Power

  2. Overview • Since the 1980s, SCE has been the nation’s leader in renewable procurement • SCE buys about 13 billion kWh per year, more than any other utility, which represents about 1/6 of the nation’s renewable energy • SCE buys over 90 percent of the solar energy produced in the U.S. • SCE continues to lead the way in renewable procurement • Since 2002, SCE has conducted 3 solicitations for renewable power and is completing a fourth • SCE has signed 23 new contracts, representing annual deliveries of up to 13 billion kWh • SCE has championed innovative technologies and creative commercial relationships • SCE leads the development of much-needed transmission • SCE will advance $1.8 billion to construct transmission to access 4,500 MW of Tehachapi wind resources • SCE is seeking CPUC authority to study the feasibility of building transmission to access resource rich areas in Western Nevada, Mammoth Lakes, the Salton Sea area, and San Bernardino County

  3. Renewable Percentage in 2002 Renewable Procurement 100% = 11,656 GWh Biomass (10%) Wind (22%) 2002 renewable procurement percentage = 15.6% Solar (7%) Small Hydro (9%) • Purchases 475 GWh • SCE-owned 529 GWh Geothermal (52%) Note: The RPS compliance percentage is calculated by dividing current year’s (2002) renewable procurement by prior year’s (2001) retail sales.

  4. Renewable Procurement Changes Since 2002 Annual Energy (GWh) 10,401 (15.2% Increase) Returning Direct Access Customers 2006 renewable procurement percentage = 16.8% 2,080 (15.2% Increase) 973 (8.3% Increase) Note: The RPS compliance percentage is calculated by dividing current year’s (2006) renewable procurement by prior year’s (2005) retail sales.

  5. Eligible Renewable Procurement Activity 2002 to Present 23 Contracts 13,181 GWh • Alta Wind Power (4,890 GWh) • Calpine (1,779 GWh) • Stirling Energy Systems (1,779 GWh) • Coso (1,608 GWh) • Contracts with large projects account for most renewable procurement • Contracting with smaller projects requires significant effort, but contributes relatively less to the State’s goals

  6. Projected Annual Renewable Production from Contracts Signed Since 2002 Annual Energy (GWh) 8,180 7,260 New Renewable Projects 6,300 Existing Renewable Projects 5,350 4,410 3,290 2,450 2,020 1,440 1,060 700 Completion of Tehachapi segments 1 – 11 will add 4,500 MW of transmission capacity Notes: Assumes no contract expansion options are exercised. Does not include contracts currently under discussion.

  7. CAISO Interconnection Queue By County, in MW (Summer Maximum) • Source: CAISO Website http://www.caiso.com/14e9/14e9ddda1ebf0.pdf • Data before December 2005 is estimated. * Note: Includes all counties in SCE’s service area, including additional counties not identified in figure. FERC’s rules govern CAISO requirements for fees, study requirements, and timelines It is relatively easy and inexpensive for generators to enter the queue, but exiting generators cause restudies and delays

  8. Regulatory and Legislative Actions to Support State’s Goals • Prompt regulatory approval of transmission projects and renewable contracts • Tehachapi • CPUC approval of CPCN for segments 1 – 3 by March 2007 • CPUC approval of CPCN for segments 4 – 11 by January 2009 • Timely CPUC approval of SCE advice letter seeking authority to recover costs for transmission feasibility studies • Implementation of expedited CPUC process for reviewing and approving new renewable contracts • Collaborate with CAISO and FERC to promote renewable development • Facilitate early interconnection of renewable projects • Revisit interconnection queue policies • Consider legislation authorizing regional (WECC) RECs for California RPS compliance to increase supply and development opportunities and reduce overall program cost • Continue to allow counterparties to develop mutually acceptable contract terms consistent with current market conditions • Developers need flexibility to accommodate different technologies and business arrangements • Prescriptive contract terms chill innovation, reduce project viability, and increase customer costs
