5 Agenda 2. Review Roberts Rules of Order AGENDA 2 2. Review Roberts Rules of Order Parliamentary Procedures. Based on Robert s Rules of Order, Newly Revised, 10 th Edition Establishing a Quorum. In order to make efficient use of time at MRO Committee meetings, once a quorum is established, the meeting will continue; however, no votes will be taken unless a quorum is present at the time any vote is taken. Motions. Unless noted otherwise, all procedures require a second to enable discussion. When you want to Procedure Debatable Comments Raise an issue for discussion Move Yes The main action that begins a debate. Revise a Motion currently under discussion Reconsider a Motion already resolved End debate Record each member s vote on a Motion Postpone discussion until later in the meeting Postpone discussion until a future date Remove the motion for any further consideration Request a review of procedure Amend Yes Takes precedence over discussion of main motion. Motions to amend an amendment are allowed, but not any further. The amendment must be germane to the main motion, and cannot reverse the intent of the main motion. Reconsider Yes Allowed only by member who voted on the prevailing side of the original motion. Second by anyone. Call for the Question or End Debate No If the Chair senses that the committee is ready to vote, he may say if there are no objections, we will now vote on the Motion. Otherwise, this motion is not debatable and subject to majority approval. Request a Roll Call Vote No Takes precedence over main motion. No debate allowed, but the members must approve by majority. Lay on the Table Yes Takes precedence over main motion. Used only to postpone discussion until later in the meeting. Postpone until Yes Takes precedence over main motion. Debatable only regarding the date (and time) at which to bring the Motion back for further discussion. Postpone indefinitely Yes Takes precedence over main motion. Debate can extend to the discussion of the main motion. If approved, it effectively kills the motion. Useful for disposing of a badly chosen motion that cannot be adopted or rejected without undesirable consequences. Point of order No Second not required. The Chair or secretary shall review the parliamentary procedure used during the discussion of the Motion. Notes on Motions Seconds. A Motion must have a second to ensure that at least two members wish to discuss the issue. The seconder is not required to be recorded in the minutes. Neither are motions that do not receive a second. CLARITY ASSURANCE RESULTS

6 Agenda 2. Review Roberts Rules of Order Announcement by the Chair. The Chair should announce the Motion before debate begins. This ensures that the wording is understood by the membership. Once the Motion is announced and seconded, the Committee owns the motion, and must deal with it according to parliamentary procedure. Voting Voting Method When Used How Recorded in Minutes When the Chair senses that the Committee is substantially in agreement, and the Motion needed little or no debate. No actual vote is taken. The minutes show by unanimous consent. Vote by Voice The standard practice. The minutes show Approved or Not Approved (or Failed). Vote by Show of Hands (tally) To record the number of votes on each side when an issue has engendered substantial debate or appears to be divisive. Also used when a Voice Vote is inconclusive. (The Chair should ask for a Vote by Show of Hands when requested by a member). The minutes show both vote totals, and then Approved or Not Approved (or Failed). Vote by Roll Call To record each member s vote. Each member is called upon by the Secretary, and the member indicates either Yes, No, or Present if abstaining. The minutes will include the list of members, how each voted or abstained, and the vote totals. Those members for which a Yes, No, or Present is not shown are considered absent for the vote. Notes on Voting Abstentions. When a member abstains, he is not voting on the Motion, and his abstention is not counted in determining the results of the vote. The Chair should not ask for a tally of those who abstained. Determining the results. A simple majority (one more than half) of the votes cast is required to approve an organizational group recommendations or decision. Unanimous Approval. Can only be determined by a Roll Call vote because the other methods do not determine whether every member attending the meeting was actually present when the vote was taken, or whether there were abstentions. Electronic Votes. For an vote to pass, the requirement is a simple majority (one more than half) of the votes cast during the time period of the vote as established by the Committee Chair. Majorities. Per Robert s Rules, as well as MRO Policy and Procedure 3, a simple majority (one more than half) is required to pass motions. CLARITY ASSURANCE RESULTS

8 Agenda 3a. Approve March 13, 2018 Meeting Minutes a. The Operating Committee (OC) reviewed the minutes from the October 26, 2017 meeting. The minutes from October 26, 2017, were approved as written. b. Review and approve Operating Committee nominations. Kevin Bornhoft, Corn Belt Power Cooperative, term ending December 31, 2018 was approved as a part of the consent agenda. Kevin will be an atlarge member filling the open municipal seat. c. Review and approve PRS Charter. A request was made during the consent agenda discussion for MRO staff to hold a conference call with the OC Chair and Vice-Chair to jointly establish the next quarterly OC agenda. MRO will arrange for this prior to the May 22, 2018, OC meeting. 4. Other Business a. Reliability Impacts from Behind the Meter Inverter-Connected Generation Dick Pursley discussed the recent Canyon 2 fire disturbance in WECC that resulted in the loss of approximately 900 MW of solar resources. The majority of the solar plants tripped due to sub cycle transient overvoltages and subsequent instantaneous inverter protective action. A significant number also entered momentary cessation during and following the fault event. A detailed report can be found on the NERC website under the event analysis page. b. Integration of entities from SPP-RE Dan Schoenecker gave an update: Some of the SPP entities have reached out and visited MRO in the past few weeks. The current transition date is July 1, There is an Introduction to MRO Workshop scheduled for May 22, 2018, to provide SPP-RE registered entities with an overview of the organization, an update on transition efforts and an opportunity to meet MRO staff and tour MRO offices. The OC group is invited to the meeting and reception. Dan Schoenecker is attending the SPP Spring Workshop and SPP Board meeting on 3/29. There have been NERC calls with SPP regarding coordination of and access to databases, etc. MRO has added a page on the MRO website to allow sharing of information during the SPP integration. MRO is also looking at some possible governance changes with boards and committees. Additional staff will be hired to accommodate the expanded Region. There are currently nine new positions posted.

MRO OC Work Impact- This topic was covered above, and any feedback from the OC group would be appreciated. d Work plan- Risk Strategy- The OC group was asked to think about identifying risks in 2018 along with things that the OC group could be involved in. Dan Schoenecker identified several for consideration and the group agreed that DER (Distributed Energy Resources) should be a top priority. 5. Chair s Report- Ron Gunderson A request was made to change the next OC meeting date to Aug 7 th, pending PC meeting approval. A meeting notification will be sent out if the PC is also able to change the date. SPP-RE registered entities that will be transferring to MRO will be encouraged to attend any of the upcoming OC/PC meetings as a guest going forward during the transition. 6. Review of Event Analysis a. Review of Events since Last Meeting- John Seidel gave a brief overview of the events since the last meeting. b. Recommendations and Lessons Learned- Bill Kunkel and Dick Pursley- Ron Gunderson asked if there was any training MRO could provide regarding Lessons Learned and what are the expectations of registered entities. The new MIDAS taskforce that is being formed to develop a guidance doc on proper MIDAS submittals should be completed by the end of the year. c. MRO Metrics Review- John Seidel went over the BES event metrics. d. Draft Category 1h. EMS Event Reporting Form- Bill Kunkel reviewed the new brief report template that will be used for EMS-related outages. This template will be specific to EMS-related outages. 7. Reliability Coordinator Reports; The three reliability coordinators within MRO were requested to provide a brief update on Winter 2018 conditions. a. MISO: Mr. Raja Thappetaobula discussed MISO 2018 winter performance. Severe cold weather was experienced in the early and mid-january. The MISO South region experienced record peak loads on January These record loads along with forced generation outages resulted in a maximum generation event. The event was managed by implementing DSM and Emergency Energy Purchases. A new MISO wind peak output was also set on January 17 with an output of 15,038 MW. CLARITY ASSURANCE RESULTS

10 Agenda 3a. Approve March 13, 2018 Meeting Minutes b. SPP-RTO: Mr. Terry Oxendale discussed the SPP-RTO winter performance. Wind output of about 15,500 MW was realized in March and at one point was serving 59% of the SPP-RTO footprint load. During high wind output days, curtailments continue to cause some large powerflow swings on the system. Five minute dispatch may be slowed down during these times to reduce the volatility on the system flows. Both MISO and SPP_RTO are working to smooth out this operational issue. c. SaskPower: Mr. Cordell Wrishko discussed the winter performance on the SPC system. An all-time winter peak load record was set on December 29, 2017 with 3792 MW of load. In general, the weather has been near normal this winter in Saskatchewan and the system has performed well. 8. Spring Reliability Conference- The group reviewed the draft agenda topics and speakers for the upcoming Spring Reliability Conference. Draft Agenda/Speakers: Keynote: Lloyd Linke- NERC Reliability Issues Steering Committee Human Performance and Skilled Workforce- James Merlo, NERC Transmission Voltage Control Challenge- Chuck Lawrence ATC SPP-RTO: Operational Characteristics- Derek Hawkins, SPP-RTO EMS Applications and the Impact of Unavailability- Venkat Tirupati Managing Generation Availability in Real Time- Kevin Vannoy, MISO Substation Equipment Failure Modes and Mechanisms, NERC It was requested that we add the following to feedback forms: - Topics for webinars - Topics for conferences 9. Risk Assessment and Mitigation Updates- Ben Lewiski and Jeff Norman RRA Follow up items: Market dispatch models Joint ownership concerns- best practices, could be a webinar or topic for Reliability conference. Trends from violations/lessons learned. Real time assessments: TOP R13 waiting to be approved. OC could review and put thoughts into the document.

Review of Events Since Last Meeting MRO Staff Date: May 22, 2018 To: Subject: Action: MRO Operating Committee (OC) Event Analysis Report in MRO Region Information Only Operating Committee Members: The following is a summary of new event analysis reports that have been submitted to MRO since the last OC meeting on March 13, New Events Reported Since the Last OC Meeting: Since the last OC meeting on March 13, 2018, there were no EMS-related brief reports received One category 1.a brief report was submitted for a Bulk Power System (BPS) event through May 10, March 23, 2018 Event in the Minnesota: This event is pending cause-coding with the entity. Event Category: 1.a # of BES facilities Interrupted: 3 MW of Generation Lost: 0 MW MW of Load Lost: 0 MW # Misoperations: 1 Details: A fault occurred on the Lakefield Junction to Nobles 345kV line. The fault was initiated by galloping due to a storm in the area. Relay records indicate arcing occurred between the Lakefield Junction and Nobles 345kV line and the Lakefield Junction to Dickinson County 161kV line. Because of the nature of the fault, the distance elements at Nobles did not see the fault. The ground time over-currents (TOC) timed out on 345/161 kv Transformer 10 at Nobles and operated before the line relays TOC could operate to isolate the line. This was due to a miscoordination that existed between Transformer 10 and the line s TOCs. The line tripped out 6 cycles later. Two reclose attempts (one automatic and the other manual) were attempted to put the line back inservice but they both failed. The line was put back in-service the next day morning.

14 Agenda 6a. Review of Events Since Last Meeting Mis-coordination between Nobles Transformer 10 51N elements and the Nobles to Lakefield Junction 67G1T elements was responsible for the Transformer 10 misoperation. Transformer 10 and Transformer 9 settings were revised and the changes have been implemented in the field. The 161 kv line ground distance elements performance is still under evaluation.

The RC is responsible for reviewing and approving new, modified, or retiring RASs. The PC is responsible for the periodic review of existing RASs on a five year cycle to assure they are still effective for the identified system conditions and to assure they coordinate with any other RASs that might interact with them. The effective date of this transition is January 1, MRO staff held a conference call with MISO staff on April 23, 2018, to coordinate the transition of RASs within their footprint. Of the 30 active RASs within MRO, roughly half are within the MISO tariff footprint. Several of these will be retired in 2018 upon completion of system reinforcements and changes that are nearing completion. Additionally, five Manitoba Hydro RASs will transition to MISO for any RC reviews that may be necessary and two Minnkota Power RASs will transition to MISO via contracted PC and RC services. MISO staff has indicated that they will budget for a stakeholder group to be formed in 2019 to perform RAS reviews. Until that time, the MRO SPSWG will continue to perform RAS reviews as necessary through the remainder of 2018 and MRO staff has corresponded with SPP-RTO staff regarding the transition of the five RASs that are within SPP-RTO. More discussion is still needed to determine this transition date. Therefore, CLARITY ASSURANCE RESULTS
