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
Background
1
- 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.
Existing Long-Term Renewable Resources

California Renewable Energy Resources Act (SBX1-2) Procurement Requirements
SBX1-2 Procurement Requirements
10
- 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
SBX1-2 Procurement Requirements
11
- 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
- ther eligible renewable energy products that do not qualify
within Category 1 or 2
SBX1-2 Procurement Requirements
12
- 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

Current Activities to Procure New Renewable Resources
Long-Term Procurement Activities
17
- 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
Long-Term Procurement Activities
18
- 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
Long-Term Procurement Activities
19
- 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
Short-Term Procurement Activities
20
- 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
Market Challenges for Procuring Renewable Resources
Market Challenges for Renewable Resources
22
- 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
Renewables Market
23
- 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)

Regulatory Rulemaking for SBX1-2 Implementation
Regulatory Rulemaking Processes
28
- 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
Compliance Requirements for Publicly Owned Utilities Under SBX1-2
Enforcement Program
30
- 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
Procurement Plan
31
- SBX1-2 also requires each POU to develop a renewable resources
procurement plan
Must be prepared annually Identify mechanism(s) to be used for procurement Status update on projects under development
- RPU to develop its initial renewable resources procurement plan
in 2012
- Will bring to Board by July 2012
