The following proxies were recognized: Jim Jacoby (AEP) for Jason Atwood (NTEC) and David Mindham (ITC) for Marguerite Wagner (ITC).

(Attachment 1 – 01b SSC Agenda 08-08-18_REVISED) Background materials for this meeting can be found on the SPP website at: http://www.spp.org/spp-documents-filings/?id=20425

SSC Agenda Item 2 – Review Minutes of 07/13/2018 Meeting

MOTION: Bary Warren (SouthCentral MCN/GridLiance) made a motion to approve the minutes from the July 13, 2018, SSC meeting. The motion received a second from Bob Tallman (OKGE). The motion was unanimously approved. (Attachment 2 - SSC Meeting Minutes July 13 2018).

SSC Agenda Item 3 – Review of Past Action Items

Clint Savoy (SPP) reviewed the past action items with the group.

SSC Agenda Item 4 – RR 308

Clint Savoy (SPP) introduced Richard Dahl (MRES) to the group. Mr. Dahl proceeded through a presentation that was submitted along with the MRES comments on RR 308. The group continued to discuss the issues related to the exemption from transmission service charges and unreserved use penalties for the first 4 hours of an unplanned event, which was the purpose of RR 308. SPP staff voiced

concerns about sufficient justifications that could be used in a filing to revise the Tariff for unreserved use and transmission service charge exemptions. The group proposed that SPP staff should ask for help with justifications from stakeholders. Chair Jim Jacoby (AEP) asked for a straw poll to reaffirm the SSC policy that customers should be exempt from both transmission service charges and unreserved use charges for the first 4 hours of an unplanned transmission outage as originally approved by the SSC at its meeting on May 2, 2018. The results of the straw poll reaffirmed the original policy as previously approved. The group will propose and continue to discuss potential justifications for the Tariff revision at the next scheduled SSC meeting.

Clint Savoy (SPP) led the group in a discussion of the market impacts of the events that occurred on January 17, 2018.

SSC Agenda Item 6 – SSC Review of Physical Interconnections on the Seam

Bary Warren (SouthCentral MCN) requested that the group be provided information about existing and new physical interconnections along SPP’s seams. This would give SSC members information to consider when discussing about impacts on SPP planning and operations processes, JOAs, M2M, MISO Regional Transfers, seams cost allocation, etc. ACTION ITEM: SPP staff to present information about physical seams interconnections.

SSC Agenda Item 7 – Enhancements to the SPP-MISO CSP

Adam Bell (SPP) provided an update on the effort to implement enhancements to the SPP-MISO CSP. Mr. Bell reported that the next SPP-MISO IPSAC will be a net conference scheduled for August 27. During the IPSAC meeting SPP and MISO will be providing specific examples of how the interregional cost allocation would work if the joint model were removed regional models were used for calculating benefits instead.

SSC Agenda Item 8 – Review of 2018 SPP-AECI JCSP Final Report

The following proxies were recognized: Harold Wyble (KCPL) for Katy Onnen (KCPL), Jeff Knottek (CUS) for Tina Gaines (EDE), and Marguerite Wagner (ITC) for Jason Atwood (NTEC) [If Mr. Atwood were unavailable at the time of a vote]. The agenda was reviewed and was revised after David Kelley (SPP) requested the addition of an item for an update on the status of the Morgan Transformer Project. (Attachment 1 – 01b SSC Agenda 07-13-18_REVISED) Background materials for this meeting can be found on the SPP website at: http://www.spp.org/spp-documents-filings/?id=20425


MOTION: Bary Warren (SouthCentral MCN/GridLiance) made a motion to approve the minutes from the June 6, 2018, SSC meeting. The motion received a second from Jason Atwood. The motion was unanimously approved. (Attachment 2 - SSC Meeting Minutes June 6 2018).



SSC Agenda Item 4 – Update on Morgan Transformer Project

David Kelley (SPP) provided an update to the group on the status of the Morgan Transformer Project, which was approved through the 2016 SPP-AECI Joint Coordinated System Planning (“JCSP”) study. Mr. Kelley informed the group that the goal is to refile the method of regional cost allocation at the FERC by

the end of July. Because the proposed filing included considered benefit metrics that are not generally used when approving projects, several stakeholders encouraged Mr. Kelley to provide the same update to the SPP Markets and Operations Policy Committee (“MOPC”). Mr. Kelley agreed to provide the update to MOPC if the Chairman agreed to place the item on the agenda.

SSC Agenda Item 5 – RR 308 SPP Comments/Feedback from RTWG

Clint Savoy (SPP) provided an update on RR 308. Following the endorsement by the SSC at its May meeting the Revision Request was posted and comments were submitted by SPP staff and by Missouri River Energy Services (“MRES”). Those comments were submitted in time to be reviewed by the Regional Tariff Working Group (“RTWG”) and considered prior to taking action on RR 308. Because the SPP staff comments and proposed changes to the SSC endorsed revision request would alter the policy of the Tariff revision from what was endorsed by the SSC, the RTWG requested direction from the SSC on whether or not the group supported the RR as revised by SPP staff. The item was discussed and will be added to the agenda of the next SSC meeting. ACTION ITEM: SPP Staff to draft potential arguments for unreserved use exemption for first 4 hours of an event.

SSC Agenda Item 6 – Update on RR 313

Clint Savoy (SPP) provided an update on RR 313. Following the endorsement by the SSC at its June meeting the Revision Request was posted and comments were submitted by MRES. Those comments were submitted in time to be reviewed by the Business Practices Working Group (“BPWG”) and considered prior to taking action on RR 313. Although SPP staff disagreed with some of the MRES revisions, the BPWG approved RR 313 incorporating the proposed revisions submitted by MRES in its comments. The Revision Request will be reviewed by the secondary working groups – RTWG, Operating Reliability Working Group (“ORWG”), and Transmission Working Group (“TWG”) – before being presented to MOPC. ACTION ITEM: Post BPWG-approved RR 313 for review by the SSC.

SSC Agenda Item 7 – SPP-AECI JCSP Stakeholder Feedback

Clint Savoy (SPP) provided an overview of the stakeholder feedback received related to potential enhancements of the SPP-AECI JCSP study. Mr. Savoy reported that SPP and AECI are already discussing ways to incorporate that feedback into the JCSP process. Jeff Knottek (City Utilities of Springfield, MO) suggested that in order to prevent a one-off filing any time there is an approved project that results from an SPP-AECI JCSP an action item for the SSC should be added to develop a mechanism to regionally cost allocate seams projects to be included in the Tariff. ACTION ITEM: Develop Tariff mechanism for seams projects cost allocation.

SSC Agenda Item 8 – RTOC Update

David Kelley (SPP) provided the group a report on the recent activities of the Regional Transfers Operating Committee (“RTOC”), which meet to review the processes and events that impact the settlement agreement between SPP and MISO in FERC docket EL14-21 for the integration of Entergy into MISO. Dustin Betz (NPPD) requested SPP staff provide the SSC with a presentation on the provisions of the settlement agreement related to the MISO transmission service taken by NRG. ACTION ITEM: Summarize the provisions of the NRG transmission service charge in settlement agreement and history of payments.

SSC Agenda Item 9 – SSC Charter Review

Clint Savoy (SPP) reminded the group that it was time for the annual review of the SSC Charter. Mr. Savoy reported that Staff had reviewed the charter and did not propose any updates. ACTION ITEM: SSC Members review the SSC Charter and propose revisions as necessary.


William Ragsdale (SPP) provided the Monthly Market-to-Market update to the group.
