Process

4

Process for Updating EOP

• Review
• Continuous opportunity for stakeholder feedback
• Working groups (ORWG, BAOC, for example)
• RMS submissions
• SPP Staff will review periodically, at least annually
• SPP Staff will facilitate changes required

5

Process for Updating EOP

• Review
• Balancing Authority Operating Committee
• Review prior to posting for 14‐day general review
• Stakeholder feedback can be funneled through BAOC
• Utilize RMS for:
• Concerns
• Questions
• Issues

6

Process for Updating EOP

• Posting
• Spp.org
• Integrated Marketplace/Marketplace Documents
• This will be changing soon – stay tuned
• Two versions
• Current, in‐use version
• Redline, or draft, version (if applicable)

7

Process for Updating EOP

• Posting updates prompt notifications to:
• MOPC
• MWG
• GECTF
• ORWG
• BAOC
• Considering adding RCWG and/or GWG
• BAOC to provide at least 2/3 consent for transition
• After approximately 14‐day review, in‐use version is

replaced with updated draft version

Coordinated Activities

11

Severe Weather Alerts – Section

• SPP may take steps to assist in optimizing fuel supply:

– Conserve fuel in short supply by de‐committing resources and coordinating outages – Have participants update CROW and commitment status in Markets UI/API to reflect changes, as needed – Appeal to Stakeholders to use alternative fuels – Optimize operations to increase availability of generation – Optimize units that have limited operations hours

12

Severe Weather Alerts – Section 9.2 (cont’d)

• SPP will also consider:

– Requesting steps to ensure adequate reserves are available – Requesting steps to ensure adequate fuel supplies are available – Identifying changes in operating reserve capacity for the period

13

Energy Emergency Alert (EEA) – Section 6.3

• If an EEA 1 is declared, SPP BA will:

– Identify and curtail non‐firm sales – Commit all available resources – Identify outages that can be postponed or delayed

14

EEAs – Section 6.3 (cont’d)

• In an EEA 2, SPP BA will:

– Notify MPs of imposition of emergency ratings on resources – Utilize OEC to get assistance from RSG – Put all generation on‐line that is available – Prepare for potential load shedding – Curtail non‐firm sales – Implement plan for curtailable/interruptible loads

15

EEAs – Section 6.3 (cont’d)

• In an EEA 3, SPP BA could:

– Direct TOPs to implement load shedding plans

16

Fuel Supply and Inventory – Section 5.1

• Intent is to provide SPP with enough information in a timely

manner to properly evaluate overall fuel inventory

• Provide information that is not readily available through
• ther methods, such as CROW or Markets UI/API

17

Conservative Operations – Section 9.1

• Conditions are such, or expected to be such, that some

extraordinary measures may be necessary to maintain reliable operations – Early committal of resources – Bridging of resources – Delaying/postponing outages, if possible – Additional status updates, as needed

18

Conservative Operations – Section 9.1

• Notify Stakeholders, neighboring BAs and RC the need to operate in

Conservative Operations environment, via notifications listed in Section 4.7.

• Operate to conservative transfer limit values.
• Operate to selected double‐contingencies.
• Operate with greater unit commitment notification timeframes, including

making commitments prior to Day Ahead Market.

• Operate with increased operating reserve requirements
• Operate with increased reliability margin
• Operate with timely coordination calls, at least daily, to share reliability

information with impacted entities.

19

Notifications and Alerts

20

Communications – Sections 4.8

• Telephone call to the appropriate SPP operations desk
• Email to shiftsupervisordesk@spp.org
• CROW; updated with the outage and/or de‐rates with the

appropriate reason for status change

• ICCP
• Markets UI/API; updated to reflect any changes
• Monthly reliability call (restricted to TOPs only)

21

Alerts and Other Notifications

• RCIS is good site to access Reliability Coordinator notices

– TOPs and others should subscribe to follow notifications

22

Energy Emergency Alerts (EEA) – Section 6.3

• SPP could issue an Emergency Capacity Shortage Notification

– Section 6.3.1.2

• Load management alerts (EEA 2) could include notifications

to:

– Reduce load through public appeals – Implement load management systems – Implement voltage reduction – Implement curtailment of interruptible loads and exports

• Load management alerts (EEA 3) might include:

– Load shedding, as needed, on a pro‐rated basis at TOP level

Information & Data

24

Stakeholder Information

• Fuel Supply and Inventory, Section 5.1
• Interruptible and Curtailable Loads, Section 6.3.2.6
• Islanding or restoration information
• Loss of Necessary Applications, Section 9.4

– Systems – Data

• Reporting Issues

– Loss of load or customers

Summer Preparedness Scenario #1

26

Severe (Hot) Weather Pattern

• Assumption: Severe Weather Alert has been sent earlier

and is still in effect.

• SPP identifies a weather pattern that indicates SPP BA

will be experiencing significant load increase and potential fuel and/or resource issues due to extreme hot weather.

27

Severe (Hot) Weather Pattern

• Conditions indicate potential for:

– Stranded capacity due to transmission outages – Unexpected resource outages – Forward looking Studies indicate normal operations could lead to increased risk of sufficient BA capacity for affected period

28

Conservative Operations

• SPP has assessed the situation and determined there is

a need to enter into Conservative Operations, such that extraordinary measures may be necessary to mitigate the additional risk during the impacted period.

• SPP will issue a notification to participants of the intent

to operate under Conservative Operations mode.

29

Conservative Operations ‐ Notification

• SPP will identify the period in which the situation is

expected to last.

• SPP will identify the actions expected:

– Entities shall look at preparations of resources to ensure resource availability, as much as possible. – Entities should notify SPP of any expected fuel issues during the impacted period.

*Resource plans cannot reflect some of the conditions we need to know.

30

Conservative Operations‐ Notification

• Participants shall suspend any outages that may be

reasonably postponed or delayed until after the impacted period, unless they do not impact the situation or if the outage would somehow enhance reliability.

• All such decisions should be coordinated with SPP RC,

especially during these operating conditions.

31

Conservative Operations ‐ Notification

• SPP will identify the period in which the situation is

expected to last

• SPP will identify the actions expected

– Entities shall look at preparations to make resources available, as needed – Entities notify SPP of any expected fuel issues during the impacted period – Participants postpone or delay any outages until after the impacted period

32

Conservative Operations – Possible Actions

• SPP will consider committing units prior to the DA

Market and DA RUC to allow for fuel procurement

• SPP can decide to bridge units if the risk to re‐starting a

unit is significant

• SPP will provide daily status updates

33

Conservative Operations Alert

• Screenshot of Conservative Operations Alert email

34

Conservative Operations Alert

• Who gets the Alert:

– MPs email list – GOP RC email list and TOP RC email list – Neighboring BAs and RCs

• Mechanisms

– Emails – MUI posting – OASIS posting – RCIS posting

Summer Preparedness Scenario #2

36

Severe (Hot) Weather Pattern

• Heavy North to South flows
• Weather forecasts identify increased likelihood of

tornados in SPP BA Area

• Studies indicate normal operations could lead to

insufficient BA capacity for affected period

37

Energy Emergency Alert (EEA)

• SPP BA has identified circumstances in which SPP

forecasts its inability to maintain reserves

• SPP BA requests the SPP RC initiate an EEA 2
• SPP BA will initiate the following:

– Public appeals to reduce demand – Voltage reduction – Interruption of non‐firm end use loads in accordance with applicable contracts – Demand‐side management – Utility load conservation measures – All available generation on line

38

Energy Emergency Alert (EEA)

• SPP BA has identified circumstances in which SPP

forecasts its inability to meet demand

• SPP BA requests the SPP RC initiate an EEA 3

– Public appeals to reduce demand – Voltage reduction – Interruption of non‐firm end use loads in accordance with applicable contracts – Demand‐side management – Utility load conservation measures – May include implementing Load Shedding plans

39

Energy Emergency Alert Level 3 (EEA)

• SPP BA requests the TOPs shed load

– Load Shedding plans – Load shed calculator – Notification of TOPs – Feedback from TOPs to acknowledge relief for each
