RETI History

Inspired by SCE Advice Letter (approved as modified by CPUC Res. E-4052) and two CEC PIER contracts, all looking at the same issues1st of its kind statewide collaborative study effortIncludes IOUs, POUs, CPUC, CEC, CAISO, renewable developers, federal land use agencies, environmental organizations, neighboring state commissions, and other interested parties Commitment to open, inclusive, transparent process on an expedited schedule

10



RETI Objectives Provide a common forum for Commissions, utilities,

and developers to examine the location and timing of new generation/transmission projects

Provide a common perspective for evaluating different technologies competing for limited system resources

Develop tools and analysis methods to evaluate renewables

Support and cooperate with current transmission planning efforts

Statewide integrated transmission planning options to meet policy objectives

11

RETI Organization: Members


Coordinating Committee– Public Utilities Commission– Energy Commission– California ISO– POUs (SCAPPA, SMUD, & NCPA delegates)

Stakeholder Steering Committee– PUC, CEC, ISO, & POUs– Transmission Providers– Load Serving Entities– Generators– Environmental and Consumers Organizations– Permitting Agencies (Federal, State, Local)– Military

Plenary Group– All Interested Stakeholders

12

RETI Organization: Roles

Coordinating Committee– Oversees the overall RETI process– Ensures development of needed information – Keeps the process on schedule

Stakeholder Steering Committee– Primary working group– Key stakeholder representatives– 29 Members

Plenary Stakeholder Group– Reviews Steering Committee work– Provides feedback– All stakeholders and the public

13


Phase I of RETI will, in 8 months (August 2008):• Identify renewable-rich resource areas in California

and along its border • Confirm developable/commercial potential of

competitive renewable energy zones (CREZs) through engineering review, i.e. slope, road access, obvious environmental barriers, etc.

• Analyze the costs to develop each area, including:GenerationTransmissionCapacity valueGrid integration costsLeast cost/best fit principles

RETI Scope of Work

14


RETI Scope of WorkMost important aspects of Phase I:• We aren’t reinventing the wheel – we’re pulling

together and building on pre-existing work• Focus on actual commercial potential – not

another high level view• Consistent assumptions applied across the region• Stakeholders drive the process by validating the

work of an independent consultant through consensus input

• Goal is to rank CREZs through stakeholder consensus to reflect commercial potential, economics, and hard to quantify environmental, technological, and other concerns

15


Phase II - Transmission owners and other interested parties will develop high level transmission pathways for the highest ranking CREZs using existing transmission planning organizations/institutions

Phase III – Goal is to use existing transmission planning institutions to collaboratively design transmission plans of service that will result in applications to construct new RPS transmission infrastructure

Steering & Plenary Committee Meetings (9/20/07)• “Kick-off” meetings to establish RETI process

Steering Committee Meeting (10/29/07)• Questioned what stakeholders need from RETI• Established Sub-Committee to develop CREZ

selection/prioritization criteria

Next Steering Committee Meeting (12/17/07)• Consider proposed CREZ criteria• Discuss capacity and energy valuation factors• Address what stakeholders need from RETI
