SCE Solar PV Program

California Public Utilities Commission Workshop

July 31, 2009

  • Background and Introduction
  • Reverse Auction / RFO Process and Criteria
  • Lunch Break
  • PPA Terms & Conditions
  • In Decision (D.) 09-06-049, the Commission adopted a Solar PV Program for SCE that will result in 500 MW of new renewable energy generating capacity in SCE’s service territory over five years
  • SCE’s Solar PV Program consists of the following:
    • 250 MW DC owned and maintained by SCE (UOG), plus
    • 250 MW DC owned and maintained by Independent Power Producers (IPPs)
  • Pursuant to D.09-06-049, on July 20, 2009 SCE filed Advice Letter 2364-E requesting approval of a competitive solicitation process and criteria, and a standard contract
introduction and program summary
Introduction and Program Summary
  • Today’s workshop will focus on the competitive solicitation process and criteria, and standard contract for the IPP portion of SCE’s Solar PV Program

Solicitation Process

  • Reverse Auction
  • SCE to provide guidance on preferred locations
  • Clearly defined short-listing criteria
  • Standard 20-year contract based on AB 1969
  • Minimum of one auction per year the course of five years

Market Niche

  • Primarily 1-2 MW rooftop installations
  • Up to 10% of capacity ground mounted
  • All within SCE service territory
sce procurement background
SCE Procurement Background
  • SCE will rely upon its experience procuring power through competitive solicitation
    • Balances needs of all stakeholders (customers, counterparties, and SCE)
  • The proposed Solar PV Program process and criteria are modeled after the All Source RFO, a reverse auction in which SCE procures several hundred million dollars worth of energy and capacity every year
  • Background and Introduction
  • Reverse Auction / RFO Process and Criteria
  • Lunch Break
  • PPA Terms & Conditions
reverse auction rfo process overview
Reverse Auction / RFO Process Overview
  • Develop Reverse Auction / RFO package
  • Launch Reverse Auction / RFO
  • Receive indicative offers
  • Evaluate indicative offers, create short list
  • Finalize terms, interconnection studies
  • Receive binding price offers
  • Evaluate offers and select projects
  • Accept offers, execute PPAs, CPUC approval
1 develop reverse auction rfo package
1) Develop Reverse Auction / RFO Package
  • All documents will be specified in the Procurement Protocol, including:
    • Complete Reverse Auction / RFO instructions and timeline
    • Procedures and templates for submitting indicative offers
    • Conforming criteria for evaluation and selection
    • Interconnection applications and forms
    • Instructions for submitting Binding Price Offers

Step 1

desirable locations
Desirable Locations
  • SCE is required to “identify locations where distributed solar PV will be desirable, thereby optimizing the locational value of the project sites.”*
  • A list of zip codes will be posted online
    • Will be updated as new information becomes available
    • Will include SCE’s approximation of available capacity for new solar PV generation within each zip code
  • By providing this data, SCE does not warrant economic project viability or the ability of proposals to pass the interconnection screens or studies without upgrades

*See D.09-06-049, p. 42.

Step 1

2 launch reverse auction rfo
2) Launch Reverse Auction / RFO
  • Upon the Reverse Auction / RFO launch, information including a complete timeline of the procurement process will be made public through a dedicated website and other outreach
  • Q&A information will be updated subsequent to a Reverse Auction / RFO participants’ conference

RFO Launch

Website information becomes public

RFO Publicized

Press release

SCE emails its renewable energy mailing lists

RFO Conference

Q&A Session

Update Website

Post Q&A results

Step 2

3 receive indicative offers
3) Receive Indicative Offers
  • The proposal template for indicative offers will include:
    • A non-binding price in dollars per megawatt hour ($/MWh)
      • Including estimated interconnection costs and all tax incentives
    • Forecasted initial operation date
    • Project sponsors and reference projects
    • Completed Project Viability Calculator
      • With adequate information for SCE and the IE to populate a Project Viability Calculator
    • Physical details of the proposed project
      • Site location and ownership
      • Gross and net power ratings
      • PV technology, mounting and installation area
      • Single line diagram
  • SCE may follow up to clarify or obtain any necessary information
  • See following section for Conforming Criteria

Step 3

4 evaluate indicative offers create short list
4) Evaluate Indicative Offers, Create Short List
  • Select projects will be placed on a short list
    • Based on Indicative Offers and Conforming Criteria specified in Procurement Protocol
    • Subject to review by PRG
  • Complete interconnection application (fast track or otherwise) must be filed and deemed complete within ten business days of short list notification

Indicative Offers submitted

Indicative Offers which conform to criteria are placed on the short list

Short-listed parties are notified of their status

Filed interconnection applications must be deemed complete within 10 days

Step 4

conforming criteria
Conforming Criteria
  • Capacity should be primarily in the 1 to 2 MW range (DC) and built on rooftops
  • Levelized indicative offer must be below $260/MWh
  • Within SCE’s service territory and subject to a FERC jurisdictional interconnection agreement
  • Demonstrated site control by either:
    • Providing a roof lease
    • Providing a firm option to lease demonstrating the owner’s agreement that the PV system will be and can be installed

Step 4

conforming criteria cont
Conforming Criteria (Cont.)
  • Project must not participate in the California Solar Initiative (CSI) program or net energy metering (NEM)
    • Signed statement by roof owner acknowledging familiarity with CSI and NEM, committing not to apply for either program with respect to a Solar PV Program project
  • Must be scheduled to begin operation within 18 months of contract execution
  • Seller must have sufficient experience with large commercial and industrial roof-mounted PV installations
  • The system must be a commercially proven PV system and use UL-rated components

Step 4

5 finalize terms interconnection studies
5) Finalize Terms, Interconnection Studies
  • To the extent that any variations to the PPA terms are necessary, they will be finalized at this stage
    • Terms and conditions of the standard 20-year PPA are not intended to be subject to negotiation, but changes will be considered for unique circumstances and within time and resource constraints
  • Projects must complete an interconnection application and pass nine of ten screens or a completed System Impact Study

SCE will only continue past step 5 with proposals that are complete in all respects except for an agreement on price

Step 5

6 receive binding price offers
6) Receive Binding Price Offers
  • Eligible parties will submit a Binding Price Offer in response to the SCE reverse auction
    • One flat price, in $ per MWh (no escalation permitted)
    • Time-Of-Delivery periods and energy payment allocation factors will be incorporated into payment calculations
  • SCE reserves the right (but is not obligated) to accept any Binding Price Offer according to the terms presented

Step 6

7 evaluate offers and select projects
7) Evaluate Offers and Select Projects
  • SCE will select the lowest Binding Price Offers, subject to:
    • Local interconnection constraints
    • Maximum 10% of program capacity can be ground mounted
    • 250 MW total program target
    • Costs including time-of-use factors are not to exceed SCE’s utility owned Solar PV Program’s levelized cost of electricity (LCOE) ($260/MWh)
  • SCE is considering a multi-round reverse auction
    • Would give offerors an opportunity to improve prices to acceptable levels by submitting new Binding Price Offers
    • Offerors would be informed at time of Reverse Auction / RFO launch, through the Procurement Protocol and RFO conference, on exactly how this would operate

Step 7

8 accept offers execute ppas cpuc approval
8) Accept Offers, Execute PPAs, CPUC Approval
  • SCE will execute PPAs with selected projects
  • SCE will submit all executed PPAs to the CPUC for approval under a single Tier 2 Advice Letter

Step 8

  • Finalized timeline and dates will be released upon the Reverse Auction / RFO Launch
