BC Hydro became the RC of record for their footprint on September 2, 2019.

RC West became the RC of record for their entire RC footprint on November 1, 2019.

SPP West remains in shadow operations and is scheduled to go live on December 3, 2019 for SPP West RC expanded footprint.

The Chairs of ORS and RS presented overviews of the activities of their respective Subcommittees at each other’s recent meetings. The groups will continue to look at ways to assist each other with their work plans.

As part of the 2019 ORS Work Plan, the ORS reviewed:

Time Monitoring and GMD Reference Documents – The task team provided a final draft of changes that the ORS reviewed and expects to endorse at the November meeting. The documents will be provided to the NERC OC for endorsement at the next OC meeting

Dynamic Transfer Reference Document – The ORS and RS presented a final revision of the document which the ORS endorsed. The Pseudo Tie Coordination Reference Document and Dynamic Tag Exclusion Reference Documents have be incorporated into this single Reference Document. The document will be provided to the NERC OC for endorsement at the next OC meeting

In addition to the initial Work Plan, the following documents were also drafted and endorsed as indicated by the ORS:

Endorsed: Revisions to the NERC RC Hotline protocols to account for the additional RCs in the Western Interconnection

Endorsed: A new NERC Emergency Conference Call procedure. The procedure will serve as a mechanism to initiate a conference call with RC management in the event of significant and unexpected system conditions to allow for strategic discussions and information sharing.

Drafted revisions to the RCIS Reference Document. The document is being reviewed and updated to ensure consistent and relevant information sharing practices amongst the RCs and tailored appropriately for each Interconnection.

The ORS added new members Tim Beach (RC West), Darren Wilkie (AESO) and John Norden (ISONE) to the ORS Executive Committee.

ORS continues to receive updates from the EIDSN Steering Committee pertaining to the IDC Tool enhancements. Specifically, the Parallel Flow Visualization (PFV) project, which is intended to improve the data quality used by the IDC during curtailment of Eastern Interconnection transactions. For next steps, ORS anticipates that OC approval will be sought in early to mid-2020 for go-live of PFV in October of 2020 following additional parallel operations and testing of PFV.

The group discussed the role of the Eastern Interconnection Frequency Monitor. TVA has filled this role for many years. ORS will review the TVA procedure and consider at the February meeting whether the monitoring is providing a reliability value and should continue or if it should cease. If

Reliability and Security Technical Committee Update and Transition Plan (Item 7)

David Zwergel, RSTC Vice Chair reviewed the information presented at the Joint Meeting regarding the RSTC. Sector elections run through December 20, 2019 and At Large nominations will open December 30 through January 10, 2019. He noted that there are a lot of questions to be considered? What will be the length of meetings? Frequency of meetings? What do the report outs look like? Will each subcommittee report at each RSTC meeting? Do we need any forums? Do we need to have closed sessions for sensitive date/reports? He opened the floor for input from the OC on the transition plan and RSTC related questions/comments:

Set up a catalog of reoccurring items that require approvals versus one-off items. Subcommittee chair and vice chairs develop this list and return in March, 2020 to report out to OC.

RSTC meeting structure – how do operations observers focus on operations issues rather than having to be in the meeting the full time for planning and security issues?

How do we integrate/align the OC, PC and CIPC strategic plans?

What will the meeting schedule look like?

Consider reviewing the first couple of meetings to assess effectiveness.

Meeting Minutes – Operating Committee – December 10-11, 2019 12

A lot of topics are converging between the three committees and we have an opportunity to look at various aspects (operations, planning and security) of each topic for discussion.

Communicating with members and observers will be important.

How will the RSTC deal with specific issues of operations, planning or security? Consider empowering the subcommittees to have more autonomy.

How will the RSTC stand up task forces? Where will they find the people to form the task forces?

Each new task force need clearly defined scope with sunset provisions. WECC Reliability Coordinator Update– James Hanson, WECC staff (item 8)

James provided an update on the activities relating to the RC initiatives in WECC. The map shows the RC areas for December 3, 2019.

RC updates at each Operating Committee meeting OC Work Plan Update (Items 9a, 9b, 9c, and 9d) Chair Zwergel asked each subcommittee chair to review their proposed 2020 Subcommittee work plan. Chair Chris Pilong reviewed the ORS proposed work plan. Peter Brandien made a motion to approve the OS work plan. The motion passed without dissent. Chair Pruitt reviewed the RS proposed work plan. Luke Weber made a motion to approve the OS work plan. The motion passed without dissent. Vice Chair Sink noted that the PS work plan will significantly change with the transition of PS Activities to the PCGC. The OC will table this work plan. Chair Hydzik reviewed the EAS proposed work plan and noted that the EAS has a number of reoccurring work plan items. David Cullum made a motion to approve the OS work plan. The motion passed without dissent. Reliability Issues Steering Committee (RISC) Status Report (Item 10) Chair Zwergel presented an update on the activities of the RISC. The RISC presented its 2019 report to the NERC Board in November, 2019. The report was accepted by the Board. He noted that the RISC identified current and future risks to the BPS. They had a reliability summit earlier this year and conducted a survey

Meeting Minutes – Operating Committee – December 10-11, 2019 14

to get input on the report. The goal was to make the report more concise and actionable. It is anticipated that the RSTC will work on mitigating the risks identified in the RISC report. Lessons Learned – Rime Ice (Item 11) Wayne Guttormson, Sask Power, gave a presentation on their December 4, 2018 Islanding Event for the OC. Several grid transmission lines, generating units, and bulk delivery points tripped off as part of this event, due to extreme and widespread rime ice conditions. Heavy fog, no sun, mild temperatures and light wind conditions persisted across Saskatchewan for days. The intensity and persistence of these conditions resulted in the formation of large amounts of rime ice on transmission lines, through gradual accretion. Rime ice forms when water droplets in fog freeze onto cold surfaces. Rime ice is more brittle that clear ice and is typically knocked off by movement of the conductors due to wind. Overhead shield wires on transmission lines are more susceptible to rime ice build-up compared to phase conductors, since they do not carry power. Heavy accumulation of rime ice on a shield wire can cause it to sag down to the phase conductors. Outages typically occur due to contacts between the shield wires and the phase conductors. These outages are often temporary and the line may be restored to service once the line is de-energized and fault is cleared. However, transmission line structures can also be damaged when shield wires break, due to force exerted on the structure when the tension of the wire is suddenly released and this resulted in multiple permanent transmission line outages. The SaskPower system remained stable, with external interconnections and most bulk delivery points restored within hours. The intensity and persistence of this rime ice condition is rare for such a widespread area, and is beyond what industry would consider. Transmission line shield wires are at risk to fail, especially for older lines, and storm damage to wires increases future risk of breakage. Effective emergency response and preparedness plans are critical. SaskPower’s corporate process that is used to manage the response to emergency incidents proved to be extremely beneficial. Effective communication (internal and external) is a key to success, and material availability is crucial. Joint Meeting Topic discussion (Item 12) Chair Zwergel recapped the Joint OC/PC meeting topics and opened the floor for discussion by the OC. The Joint meeting topics were:

1. Welcome – John Moura, NERC

1 - Relaying and Protection Systems January 11, 2019 Oscillation Event (Item 13) Tim Fritch, TVA provided an overview of the oscillation event. On January 11, 2019, a steam turbine at a combined cycle power plant in Florida experienced a faulty voltage measurement to its turbine control system that resulted in oscillations that persisted for around 18 minutes before the plant operator manually removed the unit from service. The turbine experienced oscillatory behavior that occurred near a 0.25 Hz frequency (a four-second periodic behavior) that interacted with the natural system modes of the Eastern Interconnection (EI). For this reason, the oscillation propagated through the entire EI and was observed by Reliability Coordinators across the EI. This disturbance report documents the analysis of this disturbance and provides key findings and recommendations for industry moving forward.

TPs, PCs, and RCs should continue oscillation studies to understand current and future system modes

Current modes: real-time operations

Future modes: planning assessments, changing resource mix, dispatch patterns, technologies, etc.

Improved observability of inter-area oscillations

Additional PMUs in certain areas needed (being added)

Standardized data formats for off-line engineering analysis

PLU and other cyclic controls should not be set to coincide with reciprocal of system mode frequency (f = 1/T)

Redundancy in turbine control system needed

Operator training – appropriate actions during oscillation events

Operating procedures for taking appropriate action to mitigate or eliminate sustained/undamped oscillations

Interconnection-wide oscillation tools needed

Interconnection-wide PMU-quality data set needed

Timely/effective source location is crucial for mitigation

RC coordination with neighboring RCs and GOPs

OC Strategic Plan review team (Item 16) Vice Chair Hils reviewed the updated OC Strategic Plan document. Bill Chambliss made a motion to approve the updated document. The motion passed without dissent. NERC Operating Reliability Data (ORD) Confidentiality Agreement and Data Confidentiality (Item 17) Keith Carman discussed the origins of the ORD and reminded the OC that there were many issues that the Western Interconnection entities worked out years ago in the development of the Peak RC administered Universal Data Sharing Agreement (UDSA). With Peak now dissolved the UDSA has also dissolved. In the development of a replacement agreement for the UDSA the Western Interconnection entities evaluated the ORD as a replacement for the UDSA, but the WECC entities saw issues/gaps with the ORD. A request was made to NERC to modify the ORD to address any perceived gaps and on a parallel path the Western entities began work on a UDSA replacement agreement The Western Interconnection entities developed a replacement agreement called the Western Interconnection Sharing Agreement (WIDSA), the WIDSA is held by the California ISO and all Western TOP’s and BA’s have executed the WIDSA. Candice (NERC Legal) is seeking guidance on whether or not the ORD needs to be updated in light of the fact that the WIDSA has been finalized. Cyber security is important and the ORD may not sufficiently address the issues. Keith recommends that we document what we have done/observed and pass this on to the RSTC

Meeting Minutes – Operating Committee – December 10-11, 2019 21

for them to follow through. Keith will write this up and provide it to NERC Staff for follow up by the RSTC. Chair Zwergel/Stephen Crutchfield will add this to the transition plan for the RSTC.

Takeaways

Battery Energy Storage Systems (BESS) will be installed in much greater numbers as Hybrid systems – where BESS is paired with a solar or wind site to store the excess energy that can be generated during peak irradiance or peak wind.

The BESS may be AC or DC connected.

A Hybrid system can mirror a synchronous generator by not only generating energy, but also Essential Reliability Services (ERS) – frequency response, ramping and voltage support.

They’re not coming, they’re here

Next Steps

Meeting Minutes – Operating Committee – December 10-11, 2019 29

Modeling Hybrid systems which will vary dependent on whether the BESS is AC or DC connected.

Market structure that may need enhanced products to allow the BESS to provide all services for which it is capable, possibly up to and including selling load (charging) and to provide those services at an economically favorable rate.

Policy changes that may be required for distribution-level DER to aggregate and bid the aggregated services into a market and also give the BA/TOP authority to operate those resources.

Consider holding additional workshops to focus on modeling, Market structure and policy. IRPTF: Completed document:

Reliability Guideline: Recommended Improvements to Interconnection Agreements for Inverter-Based Resources

Draft Documents:

White Paper: Terminology for Fast Frequency Response and Low Inertia Systems – NERC IRPTF Perspectives

As the BPS transitions to higher penetrations of IBR’s, synchronous inertia will decrease. The high initial rate of change of frequency (ROCOF) caused by decreasing system inertia drives the need for fast frequency response (FFR).

The IRPTF developed a whitepaper to provide fundamental reference materials related to lower system inertia conditions, the increasing ROCOF observed during high inverter-based resource conditions, the need for FFR in some interconnections, and the interrelationship between all factors that affect BPS frequency control.

White Paper: Coordinated Review of NERC Reliability Standards, and Applicability and Clarity of Standards to Inverter-Based Resources

The IRPTF undertook an effort to perform a comprehensive review of all other NERC Reliability Standards to determine if there are any potential gaps or improvements needed related to inverter-based resources. IRPTF volunteers reviewed all of the current and future enforceable reliability standards, identified potential gaps or improvements, and presented findings to the entire IRPTF. The IRPTF reviewed these findings and finalized a set of recommendations. These findings and recommendations are documented in the subject whitepaper.

The IRPTF requested to have OC reviewers for the two White Papers listed above. David Cullum, Darrel Yohnk, Jeff Harrison, Tom Pruitt and Luke Weber volunteered to review the documents and provide comments. The review team will provide comments by the end of January, 2020. System Planning Impacts from Distributed Energy Resources Working Group (SPIDERWG) (item 19b) Chair Kun Zhu provided an overview of the SPIDERWG activities.
