Presentation Overview

• Renewables Portfolio Standard (RPS) program overview
• Progress toward RPS targets
• Project development barriers
• Solutions for achieving RPS in a cost-effective and
  timely manner

Overview of 20% RPS Program
All California retail energy sellers must procure 20%
renewable energy by 2010
• All RPS-obligated retail sellers* must have procured an
  incremental 1% of retail sales (from baseline year) in renewable
  energy per year until 2010
• 20% obligation starts in 2010 and continues indefinitely
• California has a further goal of 33% by 2020
• RPS satisfied by MWhs generated on system-side of meter and
  delivered to CA, when applicable
• Bundled contracts only now, but potentially tradable RECs soon
*RPS-obligated entities include: Investor owned utilities, energy service providers, small and multi-
jurisdictional utilities, and community choice aggregators. Municipal utilities (not regulated by the
CPUC) have a voluntary RPS obligation.

RPS Program Goals
RPS policy reflects statutory goals

• Statutory goals of the RPS include:
   – Diversifying California’s electricity supply for reliability, public
     health and environmental benefits
   – Promoting stable electricity prices by hedging against volatile
     natural gas prices
   – Stimulating sustainable economic development
   – Developing competitive procurement process to obtain least-
     cost, viable MWhs in a short time frame (“cost, risk, time”)

Status of RPS Procurement
Recent RPS solicitations have been robust
• CPUC has approved ~166 contracts for over ~13,000 MW of new
  and existing eligible renewable energy capacity
    – ~5,000 MW of long and short term contracts currently under review
• ~1080 MW of projects under long-term contracts have come online
  since 2003, 50% out-of-state
• ~1000 MW of projects under short-term contracts have come online
  since 2003; 99% out-of-state
• Participation in RPS solicitations is increasing:
    – Greater participation from larger and more experienced developers
    – Dramatic increase in number of solar PV bids
    – 2009 RPS solicitation resulted in 100,000 GWh of bids
    – Shortlisted 2009 bids would meet half of IOUs’ 33% target

RPS Procurement Process

    CPUC                                      IOU rank bids
                     IOUs hold                                         IOUs negotiate
approves RPS                                    pursuant to
                       annual                                           bids, execute
 procurement                                “least-cost, best-
                    solicitation                                          contracts
    plans                                   fit” methodology

                   • Independent evaluator oversees solicitation, bid evaluation, and
                   • Utilities can also sign bilateral contracts

 Once the IOU executes contract, must submit to the CPUC for approval

Project Development Barriers
RPS solicitations attract larger projects, which face
project development risk and take time to develop

• Of 140 approved contracts, 23 have been terminated and 10 are
  delayed (have missed commercial online date)
• CPUC identifies and tracks the development barriers for each
  approved RPS project
• Significant project development barriers:
     - Transmission                                   - Technology maturity
     - Permitting (CEC and County)                    - Fuel supply
     - Site control (e.g., BLM application process)   - Equipment procurement
     - Project financing                              - Military radar
     - Developer experience

CPUC Working on Solutions
CPUC is working to create multi-agency solutions to
known barriers
•   Tradable Renewable Energy Credits (TRECs)
     –   Increases procurement options and increases competition

•   Renewable Energy Transmission Initiative (RETI)
     –   Identifies most cost-effective renewable resource zones and transmission to access them

•   33% Implementation Analysis
     –   Analyses costs and tradeoffs between various 33% RPS scenarios

•   More robust long-term procurement planning methodology
     –   Streamlining inputs and assumptions in utility procurement scenarios to understand their
         fossil needs in relation to all other demand and supply-side energy programs

•   Programs aimed at smaller system-side DG projects
     –   To hedge against risk and timing of larger-scale RPS projects, programs for smaller RPS-
         eligible projects emerging

Renewable Auction Mechanism
CPUC may offer new simple, streamlined opportunity
for system-side DG consistent with RPS goals
• Key program design elements of RAM include:
     – Standard Contract
          o Simple contract based on the IOUs’ existing feed-in tariff contract.
          o Terms and conditions are set before the auction and cannot be negotiated.
     – Market-Based Pricing
          o Sellers compete for a contract in a renewable auction mechanism.
          o Bids are selected by least-cost price first until the auction capacity cap is reached.
          o Price (and contract) is not negotiable and is paid as bid.
     – Project Viability
          o Minimum viability criteria to participate in the auction, e.g. 100% site control,
            developer experience constructing a project of similar technology and size.
          o Project development security, performance assurance (for >5 MW projects).
          o Project must be online within 18 months.
