Agenda 1b. Review of Robert’s Rules of Order
CLARITY ▪ ASSURANCE ▪ RESULTS
AGENDA 1
Consent Agenda 1b. Review of Robert’s Rules of Order
Parliamentary Procedures Based on Robert’s Rules of Order, Newly Revised, 10th Edition Establishing a Quorum In order to make efficient use of time at MRO Committee meetings, once a quorum is established, the quorum will be considered to be in effect until the meeting is adjourned. 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
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 a Motion already resolved
Reconsider Yes Allowed only by member who voted on the prevailing side of the original motion. Second by anyone.
End debate 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.
Record each member’s vote on a Motion
Request a Roll Call Vote No Takes precedence over main motion. No debate allowed, but the members must approve by majority.
Postpone discussion until later in the meeting
Lay on the Table Yes Takes precedence over main motion. Used only to postpone discussion until later in the meeting.
Postpone discussion until a future date
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.
Remove the motion for any further consideration
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.
Request a review of procedure
Point of order No Second not required. The Chair or secretary shall review the parliamentary procedure used during the discussion of the Motion.
Agenda 1b. Review of Robert’s Rules of Order
CLARITY ▪ ASSURANCE ▪ RESULTS
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.
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
(Recommendations from EFC, not necessarily Mr. Robert)
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. The results of the vote (other than Unanimous Consent) are determined by dividing the votes in favor by the total votes cast. Abstentions are not counted in the vote and shall not be assumed to be on either side. For any votes on motions taken during the meeting, the motion shall be considered passed with 2/3 affirmative vote of the parties casting votes. For any votes on motions taken via e-mail or an electronic meeting, the motion shall be considered passed with 2/3 affirmative vote of the parties casting votes
Agenda 1b. Review of Robert’s Rules of Order
CLARITY ▪ ASSURANCE ▪ RESULTS
“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 e-mail vote to pass, the requirement is a simple majority of the votes cast during the time period of the vote as established by the Committee Chair.
Majorities. Robert’s Rules use a simple majority (one more than half) as the default for most motions. MRO does also.

d. MISO: Mr. Anthony Rowan gave a verbal update to the committee on summer
weather readiness. NOAA forecasts warmer than normal temps in the upper Midwest. There has been some severe weather in MISO south already. The summer peak load forecast is slightly below last summer’s forecast. Gas supply is sufficient and MISO has daily calls with pipeline companies to receive daily updates. There have been no new transmission-related issues and no new IROLs.
SPP-RTO: There was no report from SPP-RTO.
SaskPower: Mr. Cordell Wrishko gave a verbal report to the committee. SPC is expecting
normal weather for summer and a peak load forecast of 3500 MW. No concerns or problems are anticipated for this summer. There are no gas supply concerns anticipated. Reservoirs are above average at this point with recent rainfall. Hydro capacity is currently 855 MW installed.

Two units (units 1 and 3) of a three‐unit coal plant were operating at about half load when 1500 MW of generation tripped off elsewhere.
The interconnection frequency dropped to 59.79 Hz.
In response to the dip in frequency, both operating coal units rapidly increased their output.
Unit 1 responded with a 205 MW/minute ramp rate while unit 3 responded with a 169 MW/minute ramp rate.

Investigation of the unit trips with the original design engineer and distributed control system (DCS) vendor, it was determined that the accumulation of plant modifications and incremental tuning (addressing many isolated issues over time) changes during the past fifteen years had altered plant response.
The DCS was no longer “in tune” with the physical plant.

The stroke times on FD and ID fans were captured. It was found that their control curves needed to be modified to align with the physical system changes that had occurred over time to improve stability.
The GO worked with the DCS vendor to schedule load ramps and testing to further tune control curves for the fans and other equipment. This was similar to performing an initial control system commissioning.

Accumulated effects of plant modifications and incremental tuning changes may significantly alter plant response over time.
Eventually, the digital model in a DCS may no longer correspond to physical reality or system requirements.
It is cost effective to obtain unit load data and perform baseline “re‐tuning” every 5‐10 years (depending on frequency of modifications) or as part of any major modification project.

Of the 13 wind plants that were on‐line, nine did not ride through the six voltage disturbances during the event. The simultaneous trip of these wind plants was reclassified as a credible contingency.
The transmission operator worked with the wind plants to identify and document their ride through capability.
As wind plants reconfigured the ride through controls they were removed from the credible contingency.
Subsequently the modified wind plants all rode through a similar event on March 3, 2017.

During Event 1, wind plant owners noted that 130 turbines tripped due to the repeated voltage fluctuations during a particular event. The turbines tripped due to voltage ride‐through parameters that were set to disconnect or reduce turbine output when a specified number of voltage excursions were detected within a given time frame.
One wind plant owner noted that 11 turbines tripped due to failed crowbar components in the wind turbine during Event 2

During Event 2, one wind plant owner noted that 12 turbines tripped due to the failure of the wind turbine auxiliary uninterruptible power supplies (UPS) devices. The owner is investigating the cause of these particular UPS failures.
During Event 4, multiple wind plant owners indicated that the voltage ride‐through tolerance for their turbines was insufficient for the magnitude of the voltage disturbance. Those ride‐through capabilities ranged from:
Less than 0.80 per‐unit for 0.08 to 0.2 seconds
Between 0.80 and 0.90 per‐unit for up to 60 seconds

Wind generation owners should review and verify the voltage ride‐through capabilities of their equipment, clearly communicate those capabilities to their BA and connected TOPs, and ensure that the models provided to the BA and TOPs correctly reflect those capabilities.
If BAs and TOPs are notified by the wind generation owners that units lack ride through capability, BAs and TOPs should communicate to their RC and BAs, TOPs, and RC should consider in their daily resource plan the potential for the loss of these resources during transmission faults on the power system. BAs, TOPs, and RCs should take appropriate mitigating measures.

To: MRO Operating Committee
From: Terry Oxendale, Planning Coordinator, SPP RTO
Subject: Reliability Coordinator Report- Summer 2017 Conditions to Date-SPP RTO
Action: Information and Discussion
The actual peak load realized so far and the 100% peak forecast as a comparison. o So far, our peak realized load was 50.7 GW o Projected 2017 RC area peak load is expected to be 51.6 GW o We’ve realized 98% of our forecasted summer peak load forecast
Any unusual or unanticipated congestion that occurred, including any critical forced outages.
o No significantly challenging, or unanticipated congestion concerns or observations thus far.
Max simultaneous wind output vs. nameplate and whether this was a new high output. o Max simultaneous wind output thus far is 16.4 GW back in April, but we nearly
matched that again in June. This is the second year in which an appreciable amount of summer wind continued past the normal spring season. This output is roughly 75% of nameplate rating for wind in our area.
Any weather related outages to the BES that required mitigation or congestion management.
o We’ve only had a single “summer” storm system that was extremely localized in the KCPL area, but transmission congestion was not a result. Other storm outages within our system have been easily mitigated with current resource dispatching. The lingering concern would be a perfect storm of high N-S flows through our system (internal flows as well as parallel loop flows from external impacts), DC tie maxed export to ERCOT, and target outages in the southeastern most portion of our system. We have good experiential knowledge of how to prepare and mitigate this situation, so this is only an awareness, but not necessarily a concern.

BES performance Summer 2017
• No unusual summer performance issues as yet Early season storm systems resulted in some forced transmission
outages, but none that resulted in any unusually challenging congestion management events.
No capacity or fuel issues Normal, to relatively mild summer temperatures, with one period in
which the north experienced a short high-heat period, while southern portion was cooler. Combined with high wind injection and high south-north flows, resulted
in an unusual, but easily managed congestion management event in the Oklahoma/Missouri area of our footprint.

BES performance Summer 2017• 2017 peak load set July 20th, at ~50.7 GW. 2017 Forecast peak load ~ 51.6 GW. So far, we’ve hit ~ 98% of our forecast seasonal peak. No reliability (transfer or capacity) issues on this day.
• Aside from the short high-temp period in the northern portion of our footprint, no unusual or unanticipated congestion this.
• For this summer, peak wind output was set June 12th, at ~13.1 GW This was 80% of nameplate ratings of ~16.4 GW. Was not a new wind peak (2017 peak set Feb 9th, at ~13.3 GW)
• No weather related outages that resulted in extraordinary congestion management activities. Have has instances of weather related forced outages, but none of
significant consequence.

Standing Committee Reports Special Protection System Working Group Report
Dave Kempf, GRE, Chair Date: July 26, 2017 To: MRO Operating Committee From: Dave Kempf, GRE, Chair Subject: Special Protection System Working Group (SPSWG) Report Action: None - Information and Discussion Operating Committee (OC) Members: Following is a summary of the activities of the SPSWG for 2017 year to date: New RAS Reviews: The SPSWG met once via teleconference/webex on June 9, 2017 to discuss a new Remedial Action Scheme being proposed in the Buffalo, ND area. The SPSWG provided feedback to the RAS owner (OTP) and these suggestions/additions have been added to the report for clarity. The SPSWG will hold a follow-up call with OTP in early August to finalize the review of the new Buffalo scheme. The scheme is expected to be placed in service this fall of 2017. Status of 2017 Existing RAS Reviews:
Manitoba Hydro - Northern Cross Tripping The SPSWG review was completed on June 7, 2017. The SPSWG had requested several clarification be made to the report to provide clarity. These enhancements were added to the RAS documentation by MHEB staff. Rich Quest (MRO) sent out a notification to MHEB staff informing them that the review is complete and meets the MRO documentation and procedure requirements of RAS reviews.
Xcel Energy - NOB-GR SPS (Nobles Co - Lakefield Junction area)
The SPSWG review was completed on April 10, 2017. The SPSWG had provided several comments and clarification requests to the RAS owner (NSP) to assure that the report was coordinated with the other entities involved (GRE and ITC). All comments and clarifications have been included in the report documentation by NSP staff. Note: This RAS will be retired upon the commissioning of the 345 kV Lakefield Junction-Huntley line scheduled for late 2017. The effectiveness of this reinforcement has already been included in the 4/10/17 RAS study documentation. NSP will notify MRO of the effective date of the retirement.
Ottertail Power Co. – Big Stone RAS Retirement
On June 30, 2017, OTP provide documentation that supports the retirement of the Big Stone RAS. The RAS was originally installed to open all 230 kV breakers at the Big Stone substation during certain breaker failure contingencies at that substation to prevent potential thermal overloads and stability issues in the area. Several significant reinforcements have occurred in the area that have increased the outlet capabilities of the Big Stone generator. This retirement study will be reviewed at the same August conf call that is scheduled for the Buffalo RAS review.
Saskatchewan Power - Boundary Dam Phase Shifting (pending)
Xcel Energy - Mankato Energy Center (pending)
American Transmission Co. - Port Edwards (pending)
RAS Criteria per PRC-012-2: At the June 9, 2017 SPSWG conf call, the SPSWG reviewed the NERC BOT-approved PRC-012-2 standard that is awaiting FERC approval, regarding limited impact RASs. Requirement 4.1.5 basically states that a limited impact RAS does not require redundancy to cover a single point of failure. A limited impact RAS is defined as: A RAS designated as limited impact cannot, by inadvertent operation or failure to operate, cause or contribute to BES Cascading, uncontrolled separation, angular instability, voltage instability, voltage collapse, or unacceptably damped oscillations. Using this NERC-approved Standard assumes that the FERC will approve the Standard as is or with slight modifications. The Buffalo RAS is a limited impact RAS. If the FERC modifies the redundancy requirement for limited impact RASs, it will not affect the Buffalo SPS since it has redundancy, but we will need to consider any potential Commission revisions during future RAS reviews.

NERC Committee Report
Terry Bilke, MRO Rep on NERC Resources Subcommittee
Date: July 28, 2017
To: Midwest Reliability Organization Operating Committee
From: Terry Bilke, MISO
Subject: NERC Resources Subcommittee Report
Action: No
The North American Electric Reliability Corporation (NERC) Resources Subcommittee (RS)
met July 25-27 at BC Hydro offices in Vancouver, BC. The complete meeting package is posted
on the RS website. The following are highlights:
The Frequency Working Group (FWG) selected events from the previous quarter to be used
for the BAL-003-1 (Frequency Response). The events will be posted on the Balancing
Authority Submittal Site (BASS). Information on the site can be found here.
The FWG approved the next revision of its events selection guide.
The FWG discussed errors induced in the calculation of Interconnection Frequency Response
(M-4 in State of Reliability Report) by sometimes capturing gross output and other times net.
The group is looking at creating a job-aid to collect better data.
The RS approved a proposal by the Reserves Working Group (RWG) on data-collection on
DCS events. With the new BAL-002 standard, only non-compliant events are reported.
Besides the number of events and % of events compliant, another key piece of information
needed for the State of Reliability Report is the number of events > Most Severe Single
Contingency (MSSC). The recommendation is to request BAs voluntarily submit their CR
Form 1 (the forms used for calculating DCS compliance) each quarter. Target date to begin
concurrent with the effective date of the new standard (i.e. 1/1/2018).
The Inadvertent Interchange Working Group (IIWG) reviewed the trend in Inadvertent
Interchange balance size. NERC has an obligation to report to FERC in 2018 the impact of
BAL-001-2 on inadvertent balances. The analysis not only looked at current balance, but if
the BA has been trending in the right direction over time. The IIWG will reach out to the
BAs trending in the wrong direction as well as those with large balances that are not drawing
them down. Balances are generally declining in the East.
NERC RS website was updated and reorganized generally around the different balancing
standards.
The RS is updating its Primary Frequency Response Guideline to address BES-connected
inverter based resources.
The RS approved updates to the Frequency Event Selection Process Document. Terry
suggested that the RS use the framework in the document to automate event selection for
BAL-003 and M-4. There is presently too much human intervention in the event selection
process, which can lead to sampling bias.
Staff updates
o Steve Crutchfield (OC liaison) noted Dave Devereaux (IESO) appointed as chair of
the NERC ORS. Lloyd Linke and David Zwergel will be chair and vice chair of
NERC OC. OC working on several reliability guidelines and lessons learned.
o Darrel Richardson discussed the SAR for BAL-002 and the two SARs for BAL-003.
The BAL-003 SAR submitted by NWPP suggesting a generator-level standard was
referred to the NERC OC for opinion. NERC decided that the other BAL-002 and
BAL-003 will be reposted for nominations. Work to begin no earlier than late
September. Those that submitted in the initial period do not need to resubmit
nominations.
o Nicole Segal (ERSWG). ERSWG will be working on forward-looking measures.
Reviewed inertia data captured under ERSWG. No significant observations as yet except
that there appears to be more than sufficient inertia in the East. Goal is to present annual data
and trends. One key piece needed in this effort is the size of the event in each Interconnection
against which inertia needs to protect.
Reviewed the M-4 (frequency response) metrics and submeasures. There is additional
refinement needed on some of the submetrics. In particular, the “C prime” metric gives the
wrong impression for the East. Even though frequency is arrested in the East and stabilized
at the “B value”, there is always going to be variability of frequency, so half the time
following an event, there will be frequency that is seen below B.
Terry Bilke gave an update on the University of Tennessee-Knoxville’s (UTK) Rate of
Change of Frequency (ROCOF) tool in FNet. Primary benefits of this notification are using
the ROCOF for situational awareness (an unusual observation has occurred), trending over
time as a proxy of inertia, and possible input to improve the FNet loss estimate (another
awareness benefit). Beyond the notification of ROCOF, the reports also note if the frequency
excursion is a MOD-027 opportunity. Terry recommended NERC capture Interconnection
load and ROCOF(s) along with events in their M-4 dataset.
Terry presented frequency performance metrics for the Interconnections from 2015 to
present. The uptick in TECs in the East has subsided. Part of this report reviewed “noisy”
frequency days (RMS1 outliers). As a trial, a representative from each of the
Interconnections reviewed 3 recent outlier days. Several lessons were learned. Terry will
work with a team to develop a process to work with the NERC ORS to review RMS1 outliers
as learning opportunities.
ERCOT, HQ, and WECC still plan to perform some type of Time Error Correction upon the
retirement of BAL-004. Terry Bilke is working with the RS chair and the RS members from
the East to reach out to Balancing Authorities on a BAL-004 transition plan for the East. A
webex was held in April with Easter Interconnection BAs to discuss current issues to include
interest in continuing some form of TEC as well as a supplementing Inadvertent Interchange
payback approach intended to reduce the number of TECs. All BAs that responded to the
survey (representing 71% of the East load) wanted to continue TEC in some form or another.
There will be a follow-up webex to present a recommended approach based on survey
results.
Reviewed an RS process document regarding the housekeeping and compliance support tasks
for modification of BA footprints as well as BA startup and retirement. The RS document
was intended to ensure proper CPS limits and RS tools (e.g. ACE monitoring, Inadvertent
Interchange reporting) worked for changes in BAs. The allocation of frequency response is a
new issue that needs to be addressed, to include situations such as the point which pseudo-tie
changes are factored into the process. Bill Kunkel will be on the team to update the
document to address these new issues.
Generator Survey. The NERC OC agreed to allow the RS conduct a series of generator
surveys this year to capture governor response information for specific events. The first
survey in the East will likely be later this year.
Staff gave an update on the Inverter Task Force. This effort was initiated due to loss of large
blocks of solar resources in the West due to transmission faults. Manufacturers are willing to
make necessary changes, but it is important to get the requirements properly stated with
regard to ride-through, normal operating ranges, reconnection logic, etc.
The next RS meeting will be Oct 31–Nov 2, 2017 at Tucson Electric’s headquarters in
Tucson, AZ.
Quiet period during holidays of 2015, process change beginning about week 66 (coincident with
bias setting change), uptick in frequency noise due to prevailing fast time beginning February.
TECs settled out following a webex with Eastern Interconnection BAs.

Date: July 26-27, 2017 To: Midwest Reliability Organization Operating Committee From: Rich Quest, MRO Subject: NERC System Protection and Control Subcommittee Report
The NERC SPCS met in Toronto on July 26 & 27. A second Canadian representative, a representative from SPP, and an industry expert in generation were added to the roster. The roster has now been culled of extraneous members, has representatives from each region, and added industry representation for currently assigned work. Industry experts are given three year terms, at the end of which continued participation is evaluated by the regional subcommittee members. It was emphasized that regions should put forth representatives based on Protection System expertise. The existing guidance document for PRC-023 was modified to address issues for which it was rejected by the ERO. A guidance document for PRC-024 is in an advanced stage. Technical methods for determining voltage settings have been formalized. During the development of guidance, flaws in the existing standard were revealed. These are associated with the determination of voltage at the “Point of Interconnection”. The guidance proposes use of nominal voltages, while the standard requires the use of voltages determined by the latest location specific Transmission Planner study. This requirement presents a moving target to the Generator Owner with zero response time allowed for changing settings. It also imposes no requirements on the Transmission Planner. The guidance document proposes the use of “Nominal Voltage”, which effectively alters the effect of the standard. Neither approach to determining the POI has any effect on the setting methods proposed, and in either case some revision to the standard would be required. A discussion of proposed changes to PRC-025 was given by a drafting team member. Those changes are currently posted for comment. A web meeting will be held in late August to approve any final changes to the two guidance documents above for presentation to the Planning Committee.

Note of Interest
Productive Meeting, we worked in small groups to produce content to the previously constructed outline for V5.0 of the CE Manual. This is by no means completed, but gives a great spring-board to begin the conversations internal, and then bring both the suggested content and meaning/thoughts behind them to the industry through a series of out-reach webinars to gain both education, engagement, and feedback from the industry as to the forthcoming changes to the program to better serve the industry. The October Meeting and the CC Meetings between will be primarily focused on two issues the remainder of the year, first with the SOCCED Deployment, and the CE Program V 5.0 creation and roll-out.
Meeting locations have been severely restricted due to travel budget issues for both NERC and the members, we will no longer “match” the OC’s Meeting Location by default, as the majority of our future meetings will be in Atlanta at the NERC Offices for the foreseeable future.

NERC Performance Analysis Subcommittee (PAS) Report Report Jaimin Patel, MRO Representative
Date: July 14, 2017 To: MRO Operating Committee From: Jaimin Patel, MRO Representative on NERC PAS Subject: NERC Performance Analysis Subcommittee (PAS) Report Action: None - Information and Discussion Operating Committee Members: Since the last OC meeting, the PAS met on June 20-21, 2017 at Montreal, QC for a face to face meeting. The next meetings of the PAS will be held on August 16-17, 2017 in Atlanta, GA. During its recent meeting, the PAS focused on reviewing the existing State of Reliability (SOR) report elements and performance metrics. Following is a brief summary of the discussion:
1. Compliance Process (CP) 1 and 2 (Chapter 5): It was proposed to remove this chapter from SOR report. However, PAS members believe this chapter should remain in SOR report adding more contexts to associate standard compliance and its impact on reliability.
2. BES Security Metrics (Chapter 7): There was significant discussion and effort by NERC in the development of this chapter. Seeking additional direction from NERC on the development of security metrics for next year SOR.
3. Event Analysis (Chapter 6): Request to submit suggestions for additional Event Analysis metrics using existing data will be made to EAS and PAS. MRO suggested,
Considering new graphs to show more sensitivity with respect to non EMS Displaying the attributes assigned to events during cause coding Reporting Cat 1h EMS events through a tool similar to MIDAS (Misoperations
Information Data Analysis System)
4. SRI (Chapter 3): Momentary and sustained outages are included in current SRI calculation. It was discussed in the meeting to recreate SRI calculation a) excluding momentary outages and b) including DC equipment outages. MRO suggested calculating SRI without momentary outages should be given top priority.

The MRO Operating Committee (OC) provides a forum for discussion and aggregation of bulk power system operational issues and best practices. The OC provides MRO stakeholders and staff with collective and diverse expert opinions on interconnected system operations to help the industry arrive at informed decisions to improve reliability. Areas that the OC and its sub-groups focus on include: system protection, special reliability assessments, event analysis reviews, Bulk Power System mis-operations, frequency response trending, along with NERC and regulatory data requests. The OC reviews and provides comments on proposed Regional and NERC reliability procedures and guidelines.

Membership Pursuant to Policy and Procedure 3 (Organizational Groups), membership of organizational groups shall be determined based upon experience, expertise and geographic diversity and to the extent practicable, shall include a balanced representation of the sectors. As such, the MRO OC is comprised of two members from each sector, providing a balanced representation of the sectors.
III. Key Objectives
• Review and provide comments on reliability assessments prepared by the MISO, SPP-RTO, and MRO Canadian reporting areas from an operational perspective.
• Review any NERC and other reliability assessments from an operational perspective.
• Review event analysis detailed reports and review and approve larger scale detailed event reports (Category 3 and higher) to assure the appropriate analysis is performed and that any lessons learned are identified and shared with the industry.
• Provide input and guidance on system protection and control matters including Standards development, mis-operation reviews, and reviews of special protection schemes.
• Participate in and represent the MRO region in all NERC groups, as required, that report to the NERC Operating Committee.
