2
• FERC Approval of EOP-010-1
• EOP-010-1 Comments Addressed by FERC Order 797
• EOP-010-1 Implementation Date
• Review of EOP-010-1 Requirements
• GMD Planning Standard TPL-007 in Development
• Next Steps

3
• NERC Standard EOP-010-1 developed to address the first stage of
FERC Order 779 which was released in May 2013.
• Order 779 directed NERC to develop GMD Standards in two stages to mitigate impacts of GMD events.
– Stage 1 – Standard to address the impacts of GMDs on BES.
– Stage 2 – Standard that require BES operators/owners to conduct initial and on-going assessments of potential benchmark GMD events.
• NERC GMD Task Force continues work on Planning Standard TPL-
007 to address stage 2.
• NERC Issued EOP-010 to address stage 1.
– Received NERC approval in November 2013.
– FERC NOPR (Notice of Proposed Rulemaking) issued in January 2014.
• FERC Approved EOP-010-1 on Thursday June 19 th , 2014 at their
June open meeting.

4
• FERC Order No. 797 (Docket No. RM14-1-000) Issued on June 19,
2014, approved EOP-010-1.
• Several commenters on the NOPR supported approval without modification.
• Other commenters raised issues regarding:
– The applicability of EOP-010-1
– Effectiveness of GMD operational procedures
– Implementation plan
– Other issues
• FERC approved the violation risk factors and violation severity levels associated with EOP-010-1.
– R1, R2, and R3 all have a VRF of Medium.

5
• FERC agreed with NERC that EOP-010-1 should only be applicable to RCs and
TOPs.
– Commenters suggested that more entities (GOPs, BAs) having a transformer with a high side wye-grounded winding with terminal voltage greater than 200kV be subject to standard.
– FERC stated NERC petition and White Paper provided adequate justification for standard to only be applicable to TOPs.
• Commenters suggested operational procedures alone are not sufficient to mitigate the impacts of GMD Events.
– FERC noted that procedures are not a complete solution to the risks of a GMD on the BES.
– However, procedures are an important first step and can be implemented quickly and more comprehensive protections will be addressed in stage two standards (TOP-007).
• One commenter suggested that a six month implementation period is not enough.
– FERC stated that no other commenters expressed this concern.
– FERC stated TOPs do not need to wait for the RC to develop an RC GMD Plan prior to the
TOP developing its own GMD Operating Procedure.
• Commenters expressed concern that EOP-010-1 does not address electromagnetic pulses (EMPs) and that NERC did not provide enough time for public discussion.
– FERC stated that Order 779 specifically excluded EMPs from the scope, and that NERC provided ample time for public discussion.

• FERC approval of EOP-010-1 occurred on June 19 th , 2014.
• EOP-010-1 states the standard will be effective:
– “The first day of the first calendar quarter that is six months after the date that this standard is approved by an applicable governmental authority”
– Six months from June 19 th , 2014, is December 19 th , 2014.
– The first day of the next calendar quarter is January 1 st , 2015 .
• One caveat to the effective date of EOP-010-1 is the effective date of R2. EOP-010-1 R2 replaces IRO-005-3.1a, R3.
– IRO-005-3.1a R3 is pending approval for retirement.
– EOP-010-1 R2 will not become effective until the day after the ret irement of IRO-005-3.1a R3.

7
• GMD Plan development in response to EOP-010-1
• R1: Each Reliability Coordinator must develop a GMD Operating
Plan that:
– Coordinates GMD Operating Procedures in its RC Area.
– Includes activities to mitigate GMD events.
– Includes a process to review GMD Operating Procedures of
Transmission Operators in RC Area.
• R2: Each RC must share forecasted and current space weather information as stated in RC’s GMD Operating Plan.
• R3: Each TOP must develop a GMD Operating Procedure to mitigate GMD events that includes:
– Steps to receive space weather information.
– System Operator response actions to preset conditions.
– Conditions for terminating the Operating Procedure.

8
• Intended to prepare MISO for GMD events.
• Gathered ideas for this plan from multiple sources.
• Utilized steps and procedures from:
– MISO RTO-OP-053-r8.1 Geo-Magnetic Disturbance Procedure
– MISO RTO-OP-018-r9.1 Conservative System Operations Procedure
– NERC GMD Task Force GMD Operating Procedure Template
– Discussion with other RTO/ISOs
• GMD Plan will detail MISO actions:
– Relay details received from NOAA
– Enter Conservative Operations
– Follow mitigation steps

9
• Any TOP subject to EOP-010-1 (TOP area includes a power transformer with a high side wye-grounded winding with terminal voltage greater than 200 kV) needs to have a GMD Operating
Procedure.
• All TOP Operating Procedures must be coordinated by their RC.
• In order for MISO to review TOP Operating Procedures and be ready for standard implementation on 1/1/15, all TOP GMD
Operating Procedures should be submitted to MISO by November
2014.
• A TOP GMD Operating Procedure Template is available here: http://www.nerc.com/comm/PC/Geomagnetic%20Disturbance%20Task
%20Force%20GMDTF%202013/Template_TOP.pdf

• Requires a planning assessment of the system for its ability to withstand a Benchmark GMD Event without causing a wide area blackout, voltage collapse, or large load loss.
– Applicability: PCs, TPs, TOs, GOs
– Need system models— DC (GIC calculation) and AC (power flow)
– Transformer information-- internal winding resistance
– Substation grounding information
• Studies that may be necessary to perform a GMD assessment:
– Transformer GIC Impact Calculations
– Power Flow System Studies – calculate reactive power loss
– Impact of Harmonics on Protection and Control
– Generator Impact Studies

11

• MISO to provide a draft version of its GMD Operating Plan
• MISO to work with the Emergency Preparedness Power
System Restoration Working Group (EP/PSRWG) to develop a process to review GMD Operating Procedures of
Transmission Operators in its RC Area.
– Process required per R1 of EOP-010-1.
– MISO proposes using a similar process established for reviewing
System Restoration Plans per EOP-006.
– Review process needs established by fall 2014.
• TOPs begin developing their own GMD Operating Procedures per R3 of EOP-010-1.
– GMD Operating Procedures need to be submitted to MISO by
November 2014 for MISO to review per new review process.
– MISO needs approximately 30 days to review all GMD Operating
Procedures prior to January 1 st , 2015 effective date.
