2008 Annual Report
Report Objectives In accordance with a Synchronized Study
Plan, identify economically beneficial transmission expansion needs and information that would be useful in the conception and design of new projects
Study Plan results from stakeholder requests and prioritization of requests with significant implications for interconnection.
Study Themes
● 2008 study themes Higher penetration of renewables (w/ &
w/o higher conservation) - 2017 Implications of carbon emissions
reduction using carbon adder – 2017 Update of production cost data base
and gas price sensitivity analysis – 2012 Completion of analysis of 2007 actual
and scheduled flows on major paths
Study Framework
● Try to achieve consistent improvement in data, models, & methodology
● 2008 study is the first full blown study building on pilot studies conducted in 2007.
● Major advance: use of NREL meso-scale wind & solar data to locate and profile resources
Study Results
Relative to 2017 base case:
● 15 % renewables scenario 5% reduction in CO2 emissions 18% reduction in gas use
● 15% renewables/20% energy efficiency results in further 17% reduction in C02 44% in gas use 5% reduction in coal Increased congestion east to west
Study Results, contd.
● 15% renewables/20% energy efficiency/$20/ton C02 adder Further 3% reduction in CO2 Further 8% reduction in gas generation 50 % increase in production costs 5 paths were consistently congested
across cases; similar to historical analysis
Transmission Paths
Flow on selected transmission paths, particularly those that connect regions, were compared between cases

Caveats re: 2017 cases
● Coal & gas prices held constant
● CO2 reductions sensitive to order in which renewables, energy efficiency, CO2 applied
● Congestion dependent on location of assumed new renewables, and conventional generation
● Renewables marginal cost = 0. Capital costs to be incorporated next cycle
Motion: Approve 2008 Annual Report of the Transmission Expansion Planning Policy committee
DOE 2009 Congestion Study
● DOE’s 2006 study resulted in designation of NIETCs. DOE received significant input from WCATF. DOE meeting of W-I and E-I in March, 2009 examined Congestion metrics Results from WECC/DOE funded historical
path analysis Featured WECC/TEPPC/SPG transmission
planning process.
● DOE to “update,” no new corridors
2009 Study Plan
● 23 study requests from 9 organizations received in November 1, 2008 – January 31, 2009 open request window
● Themes continue to expand upon aggressive renewable programs and greenhouse gas reduction polices
● Also impacts of specific transmission line proposals. Final study plan to be adopted in June.

Regional Planning Task Force
● RPTF formed by TEPPC on March 19 to oversee development of a white paper which conceptualizes enhanced western transmission planning and to prepare for, and respond to a Funding opportunity Announcement (FOA) expected from DOE in response to the America Recovery and Reinvestment Act.
Requested Board Guidance
● Support for WECC/TEPPC response to the DOE funding request according to guidelines adopted by TEPPC Flexibility to address specific requirements in
the funding request WECC staff required to support the response
process

● Renewable Planning Whitepaper
● Scenario Based Planning
● Next Steps
Stimulus Bill Language
That for the purpose of facilitating the development of regional transmission plans, the Office of Electricity Delivery and Energy Reliability within the Department of Energy is provided $80,000,000 within the available funds to conduct a resource assessment and an analysis of future demand and transmission requirements after consultation with the Federal Energy Regulatory Commission: Provided further, That the Office of Electricity Delivery and Energy Reliability in coordination with the Federal Energy Regulatory Commission will provide technical assistance to the North American Electric Reliability Corporation, the regional reliability entities, the States, and other transmission owners and operators for the formation of interconnection-based transmission plans for the Eastern and Western Interconnections and ERCOT: Provided further, That such assistance may include modeling, support to regions and States for the development of coordinated State electricity policies, programs, laws, and regulations:…”
Stimulus Bill Synopsis
Calls for DOE to:● Conduct a resource assessment and an
analysis of future demand and transmission requirements (with consultation from FERC)
● Provide Assistance to NERC, WECC, States, Transmission entities To form interconnection-based transmission
plans assistance may include modeling, support to
regions and States for the development of coordinated State electricity policies, programs, laws, and regulations
Stimulus Bill Synopsis
The language does NOT:
● Require a single transmission plan (master plan) be created
● Give authority to any entity to take action on any product created from this funding
● Change any governance structure for the Western Interconnection
DOE Identified Needs
● A body of analysis that identifies new or greatly-upgraded lines required under a wide range of potential futures
● Analyses must be transparent, and produced through collaboration among industry experts and representatives from states, federal agencies, and key NGOs
● Collaboration is essential to achieving results that key stakeholders will regard as objective and sufficient.
Status of DOE Execution
● Request for proposal not out yet
● Funding period is 5 years Money out of DOE by end of FY 2010 Cost Sharing Requirement Activity must be perpetual
● Have to show how they would coordinate their work with other entities (e.g., WGA, NREL)
Proposal Inclusions (from DOE)
● The body of work that should be done over the first 5-year period
● An organizational framework for accomplishing it
● Schedule for the work● Funds required from DOE and other sources● Other inputs required from DOE or other
federal sources● How the transition to non-federal funding
would be managed
Regional Planning Whitepaper
Purpose● Provide a framework for the WECC/TEPPC
response to provisions relating to interconnection-wide transmission planning
● Inform stakeholders about efforts to prepare a response to an anticipated DOE request for proposal
● Seek stakeholder involvement in these efforts so that the Western Interconnection is ready to submit a comprehensive funding request
Regional Planning Whitepaper
Status
● First meeting of task force to discuss details and solicit verbal feedback
● Drafting continues (3rd round)
● Next draft will be released for wider distribution
Regional Planning Whitepaper
Guiding Principles1. Does not require institutional changes2. Process will be FERC Order 890 compliant3. WECC TEPPC will provide expertise, guidance, analysis,
and options to project sponsors, Sub-Regional Groups, and stakeholder requests that come in through the WECC/TEPPC/SPG planning processes
4. WECC/TEPPC will not prescribe the specific facilities to be built, but rather will provide the critical intelligence to state and federal decision-makers about overall west-wide needs and solutions
5. The planning process will include extensive outreach opportunities for stakeholders to participate, interact and comment throughout plan development.
26
Scenario Based Regional Planning
● Instead of trying to predict the future, we quantify needs under potential futures Quantify effects of policy, societal values,
economy on the electric power industry
● Look for common solutions among many needs
● Decision support for policy activities
Scenario Planning Paradigm
28
What will change
● Increase the breadth and depth of TEPPC regional planning activities
● Breadth Many more generation/load scenarios Additional tools and study methodologies More involved parties
● Depth Direct tie back to policy decisions Total cost comparisons
What will NOT change
● Evolving TEPPC coordination with other committees
● Process compliance with FERC 890
● Role of subregional planning groups
● No endorsement of specific projects
Next Steps
● Support for WECC/TEPPC response to the DOE funding request according to guidelines adopted by TEPPC Flexibility to address specific requirements in
the funding request WECC staff required to support the response
process
●Continue drafting process Incorporate today’s discussion
