• Joint dispatch of electricity via SPP's wholesale market under a single set of rules • An expansion of SPP's Regional State Committee to include state commissioners from the
Mountain West region • Staged approach with RC services going live before the BA and Market. • Additional information available at https://www.spp.org/mountain-west/
When asked, Mr. Aclin noted that as of now, there are no plans to share regulation over the DC ties. There is also an effort underway to review and revise drafts of the SPP governing documents by May 2018. These documents include, but are not limited to, the SPP Tariff and Market Protocols. The process of adding new members to the Board and various working groups is now being discussed at the Board and Corporate Governance Committee level. Additional updates will be provided at the next meeting of the BAOC. EI Frequency Excursion – Daniel Baker, SPP, shared information with the group regarding an Eastern Interconnect frequency excursion, which occurred on March 14, 2018, due to the loss of a 2000 MW unit in the North Eastern area of the United States. NERC has been leading efforts to track and improve frequency response, including a Generator Operator Survey which was sent in November 2017. The results of this survey should be available later this year. Although SPP’s response to this event was favorable, SPP could benefit from stronger language in its Criteria regarding governor response. Mr. Baker reviewed the impacts to and response from the SPP Balancing Authority during this event. Before the event, our ACE was +350 and dipped to -50 after the event. He also provided data on the overall response of SPP’s fleet by fuel type.
NERC Standards Update - Shannon Mickens, SPP, presented comments on the following:
BAL-002-3 - A 45-day formal comment period for BAL-002-3 - Disturbance Control Performance (DCS), Contingency Reserve for Recovery from a Balancing Contingency Event is open through 8 p.m. Eastern, Monday, May 7, 2018. Ballot pools are being formed through 8 p.m. Eastern, Friday, April 20, 2018. An initial ballot for the standard and a non-binding poll of the associated Violation Risk Factors and Violation Severity Levels will be conducted April 27 - May 7, 2018.
With regard to FERC’s directed modifications to BAL-002-2, the order stated: “Accordingly, we direct NERC to develop modifications to Reliability Standard BAL-002-2, Requirement R1 to require Balancing Authorities (BA) or Reserve Sharing Groups (RSG): (1) to notify the reliability coordinator of the conditions set forth in Requirement R1, Part 1.3.1 preventing it from complying with the 15-minute ACE recovery period; and (2) to provide the reliability coordinator with its ACE recovery plan, including a target recovery time. NERC may also propose an equally efficient and effective alternative.”
BAL-003-1.1 - A 30-day formal comment period for Project 2017-01 Modifications to BAL-003-1.1 Standards Authorization Request (SAR), is open through 8 p.m. Eastern, Tuesday, July 18, 2017.

However, this project could be postponed until the Standards Efficiency Review (SER) activities are completed.
Function Model Review – The Functional Model Advisory Group (FMAG) met February 28, 2018 and is inquiring of the industry if the Model is still relevant and if areas of the Model need to be revised. Mr. Mickens requested that everyone review the Model and provide feedback on whether or not any portion of it needs to be revised.
Additional information regarding the NERC Standards can be found in the attached NERC Notes. See Attachment 2 – NERC Notes.
Load Shed Test Update – Margaret Adams, SPP, informed the group that there was excellent response to the updated schedule (tests moved to every 11 weeks on Wednesdays). The test held in January showed continued improvement in participation and response. She provided an updated on the open action item to add a test that contained errors. Ms. Adams mentioned that she was working with the Shift Engineers and others to conduct a test with those requirements later this fall. She also mentioned that other tests for a partial restore and adding to an original load shed request is being developed.
Agenda Item 4 – AGC Control Modes for Units Supplying Regulation
Mark Eastwood (CUS) discussed his concerns with routine plant maintenance affecting regulation capability of resources. The Protocols were reviewed regarding the selection of regulating resources at 20 minutes prior to each Operating Hour and the expectations of these resources to be prepared to provide that regulation for that hour. Reliability issues regarding resources not able to perform this regulation when selected were discussed. Also, for routine maintenance, suggestions and best practices were shared, including contacting the SPP real-time desk to provide a heads up, performing shorter maintenance items during hours when not selected for regulation, communicating with day-ahead staff regarding offers and regulation selection in order to plan for and accommodate routine maintenance.
Agenda Item 5 – Open Discussion
The committee provided updates and comments on issues impacting their locations such as mergers, audits and EMS upgrades.
Several members requested that the PowerPoint presentation be included in the posted meeting material prior to the meeting. Kim Gorter agreed to post a ‘draft’ copy of the PowerPoint presentation with the meeting material if a final version is not available.

Project 2015-10 Single Points of Failure TPL-001 The SPCS and the SAMS conducted an assessment of protection system single points of failure in response to FERC Order No. 754, including analysis of data from the NERC Section 1600 Request for Data or Information. The assessment confirms the existence of a reliability risk associated with single points of failure in protection systems that warrants further action. Additionally, the two directives from FERC Order No. 786 (p. 40 and p. 89) and updates to the MOD reference in Requirement R1, Measure M1 and the Violation Severity Levels sections have been added to the scope of the project.

Mountain West and SPP based their agreed upon terms and conditions on input from a wide range of stakeholders, state commissioners, company executives, and customers. These provisions include:
• East and west balancing authority areas
• East and west planning regions that will follow the same transmission planning processes
• Cost allocation of transmission expansion specific to each planning region
• Joint dispatch of electricity via SPP's wholesale market under a single set of rules
• An expansion of SPP's Regional State Committee to include state commissioners from the Mountain West region
• Staged approach with RC services going live before the BA and Market.
• https://www.spp.org/mountain-west/
EI Frequency ExcursionDaniel Baker
9
Eastern Interconnect lost 2000 MW
• Eastern Interconnect lost 2000 MW in the North East and frequency dipped 0.065 Hz in our area measured through ICCP. (4-10 sec samples)
• PMU data shows a frequency dip of 0.115 Hz closer to the location of event.
• This corresponds with 0.0575 mHz/MW inertia response of Eastern Interconnect.
• Our ACE was such that our AGC (RTGEN) didn’t adjust setpoints because of low ACE, so the Generation response measured for our BA between 20 and 52 sec in event should result in prime mover governor response. (speed droop). Our generation increased with 50-55 MW as result of prime mover response.
Frequency Control
• Primary – Actions provides to arrest and stabilize frequency. (governor response, load response)
• Secondary – Balancing Authority actions to return frequency to schedule. (AGC, Reserve Sharing Group Deployments)
• Tertiary Control – Balancing Authority or Market Dispatch instructions
Eastern Interconnection Concern
• The EI has experienced problems where Resource FR is “withdrawn” by outer loop controls attempting to maintain AGC setpoint
• NERC has been leading several efforts to track and improve Frequency Response
2012 NERC FRI report highlighted this decline in response
NERC BAL-003 Measurements(Also related M4 reliability metric)

Status of BAL-002-3 (SC Meeting)• Redline revisions have been made to Requirement 1 subpart 1.3 and
subpart 1.3.1 -- Subpart 1.3 - deploy Contingency Reserve, within system
constraints, to respond to all Reportable Balancing Contingency Events, however, it is not subject to compliance with Requirement R1 part 1.1 if the Responsible Entity
Subpart 1.3.1 - is (i) a Balancing Authority or (ii) a Reserve Sharing Group with at least one member that the Responsible Entity is a Balancing Authority experiencing a Reliability Coordinator
declared Energy Emergency Alert Level or is a Reserve Sharing Group whose member, or members, are experiencing a Reliability Coordinator declared Energy Emergency Alert level, and
has depleted its Contingency Reserve to a level below its Most Severe Single Contingency, and
has, during communications with its Reliability Coordinator in accordance with the Energy Emergency Alert procedures, (i) notified the Reliability Coordinator of the conditions described in the preceding two bullet points preventing the Responsible Entity from complying with Requirement R1 part 1.1, and (ii) provided the Reliability Coordinator with an ACE recovery plan, including target recovery time.

AGC Control Modes for Units Supplying RegulationMark Eastwood, Margaret Adams
46
4.4.2.1 Managing Regulation Control Status Prior to Operating Hour(3) No later than 20 minutes prior to the Operating Hour (OH), SPP will notify MPs with available qualified regulating Resources as to whether they have or have not been selected to regulate for the upcoming OH;
(a) MPs with selected Resources that are physically capable of providing regulation must submit a Resource Control Status = “Regulating” at least 10 minutes prior to the OH to ensure that the Resources will be available to clear Reg-Up and/or Reg-Down in the first Dispatch Interval of the upcoming OH.
47
4.4.2.2.3 Control Status
• Regulating (2) – Indicates that the Resource is on-line and capable of following a Dispatch Instruction, Contingency Reserve Deployment Instruction, and/or Regulation Deployment.
• Manual (3) – Indicates the Resource is on-line but not capable of following a Dispatch Instruction. (1) Start-up(2) Shut-down(3) Testing(4) Experiencing, or recovering from, a unit trip(5) Generating at an output to which the Resource is not capable of responding to a Dispatch Instruction(6) Condensing(7) Experiencing environmental, control or mechanical issues(8) Qualifying Facility exercising its rights under PURPA to deliver its net output to its host utility.
48
4.4.3.3 Regulation Deployment
• MPs providing Reg-Up and/or Reg-Down Service during the OH have an obligation to report to SPP when their Resources are no longer capable of providing the service due to physical problems with the associated Resources through submission of the applicable Resource Control Status.
• If the problem persists into the next OH, that MP must update its Resource Offer by submitting a Reg-Up Service and Reg-Down Service Dispatch Status as “Not-Qualified”.
49
Best Practices
• Update SPP before xx:40 for the next OH
• Time maintenance, where possible, according to Reg selection timeframes For example, perform a 30 minute maintenance
task from xx:00 through xx:30 during an OH in which the resource was not selected for Reg
