  1. ATC Update W. Shannon Black Sacramento Municipal Utility District Chair, WECC MIC MIS ATC TF With contribution from: Abbey Nulph Bonneville Power Administration Transmission Services Member, WECC MIC MIS ATC TF

  2. Balloting Results66% Needed to Pass • MOD-01 Umbrella 59% • MOD-04 CBM 38% • MOD-08 TRM 63% • MOD-28 Area Interchange 63% • MOD-29 Rated System Path 57% • MOD-30 Flowgates 44%

  3. Response to the BallotTwo Tracks: CBM and All Others • CBM (38%) needed a major rewrite • Primary drafters are from the Midwest and actually use CBM • All Other standards needed only minimal rewrite

  4. Current Status: CBM • Target: NERC Board Adoption – November 13, 08 • Respond to Comments - August 25, 08 • Posting for 30-day Pre-Ballot Review - August 26, 08 • Initial Ballot - September 25, 08 • Respond to Comments - October 31, 08 • Recirculation Ballot - November 1, 08 • NERC Board Adoption - November 13, 08 • To FERC - >

  5. Current Status: Other • Target: NERC Board Adoption - September 1, 08 • 30-day Pre-Ballot Review - June 20, 08 • Initial Ballot - July 21, 08 • Respond to Comments - August 20, 08 • Recirculation Ballot - August 21, 08 • NERC Board Adoption - September 1, 08 • To FERC - >

  6. Implementation Steps to Consider: MOD-01 • ATCID: Someone needs to write this document • TSP to “prepare and keep current” an ATCID • “How…implemented” R3.1 • “Such that…calculations can be validated.” R3.1. • “Manner…TSP…will account for counterflows” R3.2.2. • “Identity of [parties]” exchanging data R3.3 & R3.4. • “Allocation method” for multiple lines / parties R3.5. • “How outages are considered in ATC calculations” R3.6 • MOD-01 M3. • The TSP shall provide its current ATCID that contains all the information specified in R3. (R3)

  7. Implementation Steps to Consider: MOD-01 • Tell your People • Modelers • Must use specific assumptions. R6 / R7. • OASIS / I.T • Software and protocols • Must ensure calculation at prescribed intervals. R8 • You must post your ATCID. R5. • Changes your web page? (OASIS / NAESB)

  8. Implementation Steps to Consider: MOD-01 • Prepare for Data Exchange Agreements • Within 30 days of [Party’s] making a request, TSP must provide the data requested: • 16 items that can be requested • Subject to confidentiality • Subject solely to use in ATC calculations • Suggest pre-screen now • As frequently as once per hour. R9 & R9.2.

  9. Implementation Steps to Consider: MOD-04 • CBMID: Someone needs to write this document • TSP to “prepare and keep current” a CBMID • Telling LSE’s “How” CBM was: • 1) established, 2) set aside, 3) how to use it • Share the data • R2. TSP to “make available its current CBMID” • M2. “…shall have evidence to show that it made current CBMID available….”

  10. Implementation Steps to Consider: MOD-08 • TRMID: Someone needs to write this document • TO shall “prepare and keep current” an TRMID • Identify how 9 “uncertainties” were used. R1. • The method of allocation • The actual calculation • Share the data if asked • TSP, RC, PC, TP, TOs. R3 • Do it all again each 13 months!

  11. Implementation Steps to Consider: MOD-28Abstain

  12. Implementation Steps to Consider: MOD-29 (Rated System Path) • Tell your People • Modelers (TOs) determining TTC • Must use 10 specific assumptions. R1 • In a particular fashion. R2. • Essentially a list of “If…then” statements • Share the data R4. • Make sure you use the stated algorithm for ETCs. • R5 / R6 / R7 / R8.

  13. Implementation Steps to Consider: MOD-30 (Flowgate) • Tell your People • Modelers (TOs) creating the system model and determining TFC • Must update the model (and provide it to the TSP): • Once per day for today thru day 30 R3.2 • Once per month for months 2-13 R3.3 • Must define how source/sink and POR/POD information is used w/in the model R1.2 / R4 • Must identify Flowgates such that “at a minimum the first three limiting Elements and their worst associated Contingency combinations with an OTDF/PUF ≥5%... are included as Flowgates” R2.1 • Must update list of Flowgates and TFC values at least once per year R2.2 / R2.5

  14. Implementation Steps to Consider: MOD-30 (Flowgate) • Tell your People • Providers (TSPs) calculating AFC • Make sure to use the stated algorithm for ETCs R6 / R7 • Make sure to use the stated formula for AFCs R8 / R9 • Must recalculate AFCs (using the provided model): • Once per hour for Hourly AFC R10.1 • Once per day for Daily AFC R10.2 • Once per week for monthly AFC R10.3 • Must use the stated algorithm for conversion of AFC to ATC, though this conversion is no longer required R11

  15. The following slides are for my reference only if needed during the discussion. They are not part of this presentation.

  16. First Round Failure • Standards Failed Initial Ballot • NERC received significant comments • 370 plus!! • Dominant “No” vote was on procedure • “Standards should have been presented for comment after the standards drafting team made revisions, instead of proceeding directly to balloting.” • NERC Request for Extension. RM05-17, P. 8., April 17, 2008.

  17. Implementation Steps to Consider: MOD-04 • Tell your People • LSEs and Resource Planners • Must select a method from a menu. R3 / R4. • TSPs & TPs that maintain or establish CBM • Re-calculate it every 13 months. R5 / R6 • Allocate it per path or Flowgate. R5 / R6 • Tell the LSEs R7 / R8 • Share the data R9 • Settlements • You have to waive certain fees if CBM is used R11
