33% RPS Implementation and Barrier Analysis

Purpose: 33% RPS ImplementationChallenges Will Be Examined And Solutions Proposed Resource planning in the regulatory arena often fails to
assess implementation challenges
Environmental Review, Supply Chain Adequacy, and Contracting and Regulatory Issues each have implementation consequences
The 33% RPS examples are an opportunity to present the Commission with the challenges and propose potential solutions
3
Environmental Issues That Drive Timelines – Some Examples Examples of Environmental or Permitting Concerns
DPV2 Transmission Line West of Devers segment (tribal land) Arizona segment (another state’s approval required)
Sunrise Powerlink Transmission Line Legal and permitting risk of routing options through
Anza-Borrego Desert State Park vs. National Forest land
Ivanpah BrightSource Solar Thermal CEC and BLM coordination required to meet both
agencies’ requirements takes additional time
4
Environmental Issues Considered at Three Points – Initial Buildout
5
Environmental Screen Will Affect Initial Buildout RETI metrics by CREZ offer values that can
influence initial buildout choices RETI metrics include:
Footprint within CREZ and transmission ROW Category 1 and Category 2 lands Significant species & wildlife corridors
6
Environmental Issues Considered at Three Points – Final Buildout
7
Implementation Screen Will Support Final Buildout Use RETI as a foundation
Support RETI with supplemental qualitative information, e.g. –
Cumulative impacts (agricultural land, specific habitat types, cultural resources)
Land uses adjacent to transmission corridors requiring expansion

Environmental Issues Considered at Three Points – Implementation Analysis
9
Environmental Issues Drive Implementation Timelines Use team experience to identify potential significant
implementation challenges in the environmental process
Approval timelines by key agencies: CPUC (transmission), BLM and CEC (solar)
Effects of multiple concurrent proceedings on agency timing and workload
Availability of mitigation lands for specific habitat types
Solar PEIS scoping comments offer insight into major concerns and permitting challenges
Challenges arising in ongoing CEC and CEC/BLM proceedings (Ivanpah BrightSource, Carrizo Ausra, Stirling Solar Two)
10
Implementation Challenges Arise From Other Sources As Well Supply Chain Challenges
Contracting and Regulatory Challenges
Others?
11
Supply Chain Issues Introduce Implementation Challenges
Manufacturing capacity of renewable technologies will require expansion
Manufacturing capacity for major transmission construction may be limited
Some transmission system equipment needs to be specifically ordered with long lead time
Delays in delivery of capital in rapid expansion phases is common
12
Contracting and Regulatory Issues Introduce Challenges
The chicken and egg problem of T and G contracting, financing and construction
High contract failure rate creates planning difficulties
LTPP determination of need and other regulatory changes may increase long term contracting certainty
