Target of 20 percent renewable energy for the state Each Electrical Corporation (IOU) shall increase its
procurement of eligible renewables by at least 1% of retail sales per year to reach 20% portfolio by 2017
Local Publicly Owned Utilities are directed to: Prepare individual plans to comply with RPS Implement Legislative intent while taking into
account effect on rates, reliability, financial resources, environmental benefit and report to customers annually
Applies to Community Choice Aggregators and ESPs (CPUC rulemaking to specify requirements)
Seeks to address problem of the lack of power purchase agreements

AB 995/SB 1194 (Wright/Sher, ‘00) Extended collection of Public Goods Charge (PGC) of $135 million per year over ten years, beginning 1/1/02.
AB 57 (Wright, ‘02) Directs utilities to file annual procurement plans to the CPUC
SB 1038 (Sher/Bowen, ‘02) Authorizes expenditures of PGC, funding for new facilities tied to RPS (almost $70 million/year)
SB 1078 (Sher, ‘02) Creates RPS

By June 30, 2003 the CPUC shall adopt by rule, in consultation with the CEC:A process to provide criteria for rank ordering
and selection of least cost and best fit renewable resources
Flexible compliance rulesStandard Terms and Conditions to be used by
utilities in contracting for renewables, including performance requirements for renewable generators
A process for determining market prices
RPS: CPUC Implementation RoleRPS: CPUC Implementation Role
15
Prepare renewable procurement plan--
“least cost best fit”: Assesses “annual or multiyear portfolio supplies
and demand to determine optimal mix of renewable generation resources with delivery characteristics that may include peaking, dispatchable, baseload, firm, and as-available capacity.”
Employs CPUC’s processes to meet Annual Procurement Targets, including least-cost best-fit, compliance flexibility, and (possibly) renewable diversity.
Describes a bid solicitation.

16
Within 90 days of being deemed credit worthy, the utility would conduct solicitations to implement CPUC approved procurement Offer standardized contracts, for at least 10 years Contracts at or below market price considered
reasonable Any costs above market price can be supplemented
with PGC funds, to the extent funds are available, within caps
If unable to procure 1% in given year, 3 years to make up
Rank order resulting bids by least cost best fit Propose to CPUC which contracts to accept Sign contracts CPUC approves

17
Certify facilities as “eligible renewable energy resources”
Establish criteria for “incremental” output from existing geothermal facilities
Design and implement an accounting system to verify retail sellers’ compliance with the RPS
Verify that generation is counted only once in this or any other state
Develop comprehensive renewable electricity generation resource plan by December 1, 2003

25% of funds may go to any particular project Integrate PGC payments allowed by SB 90 with

RPS: Implementation RPS: Implementation QuestionsQuestions
Verification and Accounting? Tags? Munis/ESPs? PGC/ Market Price:
What will the market price be? Will FERC and the courts accept it?
Will the PGC funds be adequate to meet the RPS? How will PGC funds be allocated among utilities/
others? How will projects that already have PGC awards be
integrated?
