5. TEPPC Economic Studies Activity
Funding Opportunity Announcement

Key Provisions
 Create interconnection-wide, long-term, scenario-based
  transmission plans
      Identify alternative transmission system configurations
      Quantify reliability and cost implications
      Address technology and policy uncertainties
 Deliverables due in June 2011 and June 2013
 Establish a multi-constituency steering group to guide
  scenario development
      1/3 State representatives
      Non-traditional stakeholders
 Fund non-profit and non-governmental organization (NGO)
  participation in planning processes

December 18, 2009        APS & SRP 4th Quarter Stakeholder Meeting   55
5. TEPPC Economic Studies Activity
Overview of WECC response

What the proposal is:
 Extraordinary opportunity to expand the capability of planning
  processes in the West
 An extension of existing TEPPC planning process
      Ability for broader input from other stakeholders into planning processes
      Ability to study a broader range of scenarios
         Determine impact of policy and technology drivers




December 18, 2009        APS & SRP 4th Quarter Stakeholder Meeting            56
5. TEPPC Economic Studies Activity
Overview of WECC response

What the proposal is (continued):
 Improved coordination of subregional groups and WECC
  planning processes
 Ability to provide input to other critical processes
      Siting – Rating – Cost Allocation
 Process in which decision authority remains with TEPPC and
  the WECC Board




December 18, 2009        APS & SRP 4th Quarter Stakeholder Meeting   57
5. TEPPC Economic Studies Activity
Overview of WECC response

What the proposal is NOT:
 Radical shift in WECC processes
 Change in planning governance
 Significant long-term funding commitment by WECC and
  membership
 WECC involvement in siting or cost allocation processes
 No commitment to fund non-WECC activities beyond the DOE
  funding period
