RETI 1.0 (2008-2010)
RETI 1.0 was a statewide planning process to identify
transmission projects needed to accommodate
California’s renewable energy goals.
• Premise at the time:
• California law required 20% renewables by 2010;
the state had also adopted a goal of 33% by 2020.
• Development of renewable generation had slowed in
CA. Transmission was recognized as a limiting factor.
• RETI facilitated planning and permitting for transmission
to competitive renewable energy zones (CREZs)
• Broad stakeholder engagement
• B&V was the main technical and economic consultant

• Reassessed in 2013-2014
• Resource availability much more widespread and economic
• Many new wind resources in northern California
• Updates also made for performance and costs to reflect
industry advancements
• Future yearly updates planned

Thermal Project
Locations
• Solar PV not shown,
but is available across
the state (see next
slide)
• For wind, substantial
shift north, into nonCREZ areas
SOLAR PV RESOURCE (TRACKING PV)
• Widespread and
generally good quality
throughout California
• Most of resource is
outside previous CREZ
boundaries
• Worst current RPS
Calculator PV resource
still less expensive
than the best RETI 1.0!
UPDATES TO LAND USE SCREENS
• Input provided by REAT agencies to update land use
screens used in the RPS Calculator
• Last updated in 2010
• RETI Category 1 – Development prohibited
• No resources in Category 1 included in the Calculator dataset
• RETI Category 2 – these lands have restrictions or
resource conflicts unique to each area
• Calculator currently includes resources in Category 2 areas,
but can be run as a sensitivity

CREZ BOUNDARY DIFFERENCES
• RETI 1.0 CREZ Boundaries:
• Very specific, sometimes capturing specific project
boundaries and interconnection lines
• Purposefully made as small as possible (“Shrink-wrapped”)
to minimize perceived environmental footprint
• RPS Calculator CREZ Boundaries:
• Not for siting or environmental assessment - used for
categorization and assigning transmission upgrade cost
• More comprehensive coverage
• Boundaries less meaningful
• No particular advantage to being in a zone
More information on changes at:
http://www.cpuc.ca.gov/RPS_Calculator/
NEW SUPER CREZ BOUNDARIES
• All of these zones
correspond with a legacy
zone name or a zone in the
2012 RPS calculator (Los
Banos, Central Valley North)
• No new zones identified by
B&V, except Sacramento
River Valley
• Resources outsides zones
summarized by county
• Available for selection in the
Calculator
In-state boundaries with resource layers available at

RPS CALCULATOR RESOURCE UPDATES
• Black & Veatch developed new cost and
performance information from internal sources,
market data, and other literature (LBNL, DOE, CEC)
• When possible, previously-vetted information from
other Black & Veatch stakeholder projects was used

• Updates made to cost and performance based on
new design information and industry improvements
OUT OF STATE RESOURCES
• Out-of-state resources may be competitive in
certain instances
• All out-of-state of resource estimates from updated
