  2. TEPPC(Transmission Expansion Planning & Policy Committee)http://www.wecc.biz/committees/BOD/TEPPC/default.aspx • Reports directly to the WECC Board • RTEP (Regional Transmission Expansion Planning) • Approximately $14 Million grant from DOE • Regional Interconnection Wide Transmission Plan • 10-Year Regional Transmission Plan • Final report due September 2011 • Bottoms up process • Utilizes SCG Foundational Transmission Project List • Scenarios developed through SPSG & FERC 890 process • 20-Year Regional Transmission Plan • Final report due September 2013 • Utilize new Long Range Transmission Tools • SPSG will develop long range resource scenarios

  3. Approved new Charter on March 25, 2010 Addresses funding of RTEP (DOE award of $14M) Defines the SCG and SPSG Action Item: CCPG representation on TEPPC (Green/Easton) Draft Protocol (Approval set for April 26) Defines RTEP process Identifies deliverables & responsibilities of each group SPSG, SCG, PCC, and NGOs Changing to biennial cycle Approved Alberta Electric System Operator (AESO) as a Subregional Planning Group TEPPC documents available through the following link. http://www.wecc.biz/committees/BOD/TEPPC/04262010/default.aspx?InstanceID=1 TEPPC(Continued)

  7. Subregional Planning Group Coordination Group (SCG)http://www.wecc.biz/committees/BOD/TEPPC/SCG/default.aspx • Ad-hoc group that provides list of transmission projects incorporated in the Subregional transmission plans to TEPPC for a starting point in the study program • SCG Foundational Project List is due to TEPPC in April • Draft Charter • Draft Transmission Criteria • Draft Transmission Matrix • Draft Committed and Potential transmission maps • Draft Report ALL draft documents can be found by this link http://www.wecc.biz/committees/BOD/TEPPC/SCG/04212010/default.aspx?InstanceID=1

  8. SCG Charter • Responsibilities • Foundational Transmission Project List • Coordination & Communications between SPGs • 10-year Reliability assessment (not in first deliverable 2011) • Voting • Consensus based • If no consensus is reached, a majority vote by the members • Enacted until decided not necessary • Next Meeting: ? (met on April 21st)

  9. Foundational Transmission Project List • “The SCG foundational transmission project list is a subset of the projects currently in the SPG’s 10-year plans and represents those projects that have a very high probability of being built over the next ten-years and are needed under a wide variety of future resource development scenarios. The foundational transmission project list provides TEPPC with a basic set of transmission facilities that TEPPC can use as a starting point for their own studies”

  10. SCG Transmission Criteria(draft) • Subregional/Regional Transmission • All 500kV transmission lines • 345 kV considered backbone network facilities • 230 kV transmission lines with subregional significance • Committed Projects or Potential Projects

  11. Under construction Needed to meet reliability standards Required to meet WECC Loads and Resources Class 0 and Class 1 Project demonstratedfirmfinancial commitment Public statement, Inclusion in approved IRP, Major equipment orders, Executed contracts, Approved regulatory cost recovery, ROW acquired or purchasing, ISD within study timeframe All other subregional/regional projects not meeting the committed project criterion are classified as “Potential” SCG Committed Projects(draft)

  12. Committed Projects Map

  13. Potential Project Map

  14. Transmission Project Matrixfor CCPG

  15. Scenario Planning Steering Group (SPSG) • Purpose: Multi-stakeholder group to develop future resource scenarios to supplement the regional transmission planning process • 25 Member group • DOE required 1/3 representation from state/provincial group (8 Total) • Board approved membership • Required by Department of Energy under the FOA • Information can be found at the following weblink • http://www.wecc.biz/committees/BOD/TEPPC/SPSG/default.aspx
