• Schedule

• Questions and answers


NERC Antitrust Guidelines

• It is NERC's policy and practice to obey the antitrust laws to avoid all conduct that unreasonably restrains competition. This policy requires the avoidance of any conduct that violates, or that might appear to violate, the antitrust laws. Among other things, the antitrust laws forbid any agreement between or among competitors regarding prices, availability of service, product design, terms of sale, division of markets, allocation of customers or any other activity that unreasonably restrains competition.

• It is the responsibility of every NERC participant and employee who may in any way affect NERC's compliance with the antitrust laws to carry out this commitment.


Public Meeting Guidelines

• Participants are reminded that this meeting is public. Notice of the meeting was posted on the NERC website and widely distributed. Participants should keep in mind that the audience may include members of the press and representatives of various governmental authorities, in addition to the expected participation by industry stakeholders.


• Discuss stakeholder comments from first posting

• Explain drafting team’s rationale for applicability

• Present summary of revised EOP-010-1

• Outline upcoming milestones to meet filing schedule

Objectives


Order No. 779

• FERC Order directs NERC to file standards that address the impact of Geomagnetic Disturbances (GMDs) in two stages:

Operating Procedures (file by January 2014)

Vulnerability assessments and mitigation plans (file by January 2015)


Stage 1: Operating Procedures

• Standard(s) that require entities to implement Operating Procedures to mitigate the effects of GMDs

• Requirements should allow procedures to be tailored based on entity-specific factors such as geography, geology, or topology

• Consider coordination of procedures across regions

• Adoption by the NERC Board of Trustees (Board) by November 2013

Comment Responses












mailto:[email protected]


• Question 1 asked for feedback on the applicable functional entities in the draft standard

• Comments include: Review applicable functional entities

Provide a justification for 200 kV lower-bound threshold for Transmission Operator (TOP) applicability

Clarify applicability related to Bulk Electric System (BES) definition

Applicability


• Question 2 asked for feedback on Requirement R1 which requires RCs to have a GMD Operating Plan

• Comments include: Clarify the RC’s responsibility for providing space weather information to

avoid duplication with IRO standards

Improve clarity of Requirement R1 and Measure M1

Reliability Coordinator (RC) Requirements


• Question 3 asked for feedback on Requirement R3 which requires applicable entities to have GMD Operating Procedures

• Comments include: Clarify TOP’s responsibility for receiving space weather information

Include use of the defined term “Operating Process”

Support the flexibility that the standard provides to entities for developing procedures based on entity-specific factors

Requirements for Transmission Operators


• Question 4 asked for feedback on requirements to update GMD procedures periodically and maintain copies in control rooms

• Commenters viewed Requirements R2, R4, and R5 as administrative and duplicative, meeting Paragraph 81 criteria

Administrative Requirements


• Question 5 asked for any additional feedback Recommendations to extend the six-month implementation period

Importance of system studies to develop Operating Procedures

Suggestions for alternate wording

General Comments


Whitepapers posted: http://www.nerc.com/pa/Stand/Pages/Project-2013-03-Geomagnetic-Disturbance-Mitigation.aspx













• The RC has responsibility and authority for reliable operation within the Reliability Coordinator Area (RCA) NERC Functional Model provides ahead-of-time and real-time tasks

IRO-001 standards codify responsibility and authority

• Scope includes a wide-area view with situational awareness of neighboring RCAs Including RC meets Order No. 779 guidance to address the coordination of

Operating Procedures across regions (p. 38)

Reliability Coordinator


• Like the RC, the TOP has the responsibility and authority for reliable operation of the transmission system within a defined area NERC Functional Model provides ahead-of-time and real-time tasks

TOP-001 standards codify responsibility and authority

• The RC and TOP can provide the necessary level of coordination while preserving the latitude to act based on localized conditions

Transmission Operator


• The drafting team agreed with comments that there was no reliability benefit to including Balancing Authority (BA) in Stage 1

• Actions taken by the BA to mitigate effects of GMD are included in real-time balancing functions

• The BA responds to the direction of the TOP and RC RC and TOP Operating Plans, Processes, and Procedures would address the

real-time actions for the BA to take during GMD events

Rationale for Omitting Balancing Authority


• Generator Operator (GOP) is not included in the revised Stage 1 standard GOP will be considered for applicability in Stage 2

• Procedures to mitigate the effects of GMD events on Generation assets need to be supported by equipment-specific studies Monitoring equipment may be required to trigger operator actions

• Cannot assume all GOPs have studies and monitors to comply with Stage 1 standards

• GOPs with established procedures are not precluded from actions by EOP-010-1

Rationale for Omitting Generator Operator


• EOP-010-1 is applicable to TOPs with networks that include power transformers with high side wye-grounded windings with terminal voltage greater than 200 kV

• Applicability statement determines which TOPs are included in the standard based on the network operated Does not specify equipment to be protected by Operating Procedures

Not limited to BES equipment

200 kV Lower-Bound Threshold


• The drafting team views 200 kV as the minimum network voltage for a reliability benefit from GMD Operating Procedures

• Transmission line resistance, length, and DC resistance in wye-grounded power transformers influence GIC in the system Geomagnetic latitude and deep earth conductivity also influence the

impact of GIC in the system. Detailed studies are required to account for these factors.

200 kV Lower-Bound Threshold Continued


• Whitepaper presents the drafting team’s analysis: GIC modeling example where excluding 230 kV circuits results in errors in GIC

estimation

GIC modeling example where adding 161 kV and 115 kV networks has minimal impact on GIC estimation and reactive power absorption

Listing of peer-reviewed research

200 kV Lower-Bound Threshold Continued

Summary of Revised EOP-010-1

• Applicability is changed to

Remove BA

Clarify TOP with a high side wye-grounded winding with terminal voltage greater than 200 kV

• Requirement R2 added requiring RCs to disseminate space weather information as specified in the RC’s Operating Plan

Becomes effective upon retirement of IRO-005-3.1a Requirement R3

• Removes three administrative requirements

• Wording changes improve clarity of requirements and measures

• Implementation Period remains six-months


Schedule

• Comment Period: September 4 - October 18, 2013
