Emergency Operations Plan (EOP) Update Process
- -Kim Gorter
EOP Update Process
- BAOC receives redline version for review (14-days)
- Incorporate any changes and forward to Stakeholders (MWG,
GECTF, RCWG, ORWG, and BAOC) for 14 day review
- Stakeholder changes are made and reviewed by BAOC with 2/3
majority required for final redline version
- Final redline version is posted with a Publish Date and adjacent
BAs and RCs are notified.
- On Publish Date, IN USE version is created from the redline
version.

Does the EOP update process allow enough time for review and input?
Short-Term Reliability Unit Commitment (STRUC)
- -Yasser Bahbaz
Short Term RUC - STRUC
- Runs every 15 minutes for 180 minutes window.
- 150 minute commitment period
- Committable window
- 30 minute near window (RTBM window)
- Not committable
- The intent of the study is to give intra hour granularity and more frequent
evaluation of the system in terms of generation needed to commit.
STRUC
- Will, in the future, provide an enhancement to the Quick Start
resources and how they are dispatched in real time.
- STRUC will be the study to indicate to RTBM whether a Quick
Start qualified and registered resource should be dispatched by RTBM
- For now, Quick Start either opt-in or out of STRUC.
- Resources Opting-in will be committable by the study
- Resources Opting-out will not be committable by the
study
Network Topology
- RTBM window
– State estimator topology
- Commit window
– Apply Outages on top of SE topology – Restore the Outages which end in the intervals. – Restore all Market Units not isolated by other equipment
- utages so that they are available for commitment by ST-RUC.
Unit Commitment
- Resources are committed based on,
– Ability to start within the study window – Start Cost and No load – Needed products qualification – Existing commitments in COP are respected by STRUC – Ability to recuperate cost in the desired commitment window
- 15 – 180 minutes
- Headroom
- STRUC Headroom = Hourly base headroom converted to quarters
Example: 900MW Hourly requirement = 225MW STRUC Requirement from
- ne 15-minute interval to the next
Product Clearing
- Energy:
- 15-minute ramp is used to dispatch resources within the study
- Regulation
- 5 minute ramp to clear Regulation Up and Down
- STRUC uses existing Regulation Selection and,
- May select additional qualified resources if not DESELECTED
- Spin/Supp
- 10-minute ramp is used to dispatch resources within the study

Resource Management
State Non-committable Window Committable Window Not in COP for entire study and observed SCADA Echo SCADA MW if the resource is not in startup and shutdown window. Fix at 0MW if the resource is not in startup/shutdown window. The resource is not committable by STRUC. Not in COP for first few intervals and
- bserved SCADA
Echo SCADA MW if the resource is not in startup and shutdown window. Scenario 1: If the resource is not eligible for ST-RUC commitment (i.e. not flexible), then echo SCADA MW until the interval in which startup profile is applied for the future planned commitment. Scenario 2: If the resource is eligible for ST- RUC commitment (i.e. flexible) in intervals in which there is no planned COP, then ST-RUC can commit (or advance the future commitment) the resource. If STRUC decides not to change the commitment (due to economic reasons), then the resource is dispatched at 0MW till the interval in which the future planned commitment. There is no startup profile built in this case. In COP for the entire study but SCADA is 0 Fix at 0MW Fix at 0MW. The resource is not committable by STRUC. In COP for the first few intervals and SCADA is 0 and resource is committed again in STRUC window. Fix to 0MW Fix at 0MW in the intervals until next start. After that, follow COP and the resource is committable and dispatchable. In COP and submitted CMODE=3 Echo SCADA MW Follow COP and the resource is committable and dispatchable.
Commitment Expectations
- Intra hour blocks for short term ramp needs for Energy and
Operating Reserves
- Control flowgates more reflective of near real time conditions
- Extending or early starting resources with commitments for
congestion management or meet needed demand for market products
- Allow SPP operators to hold off commitments longer for
resources that are flexible, based on start up times, until closer to real time to further ensure the need for the commitment.

Wind Integration Study
- 60% Wind Penetration Wind Output and Siting.
25
Wind Integration Study results
- The Steady-state thermal and voltage analysis confirms the need
for approved ITP projects
- Additional transmission needs beyond what was approved in the ITP
process was discovered
- Some approved ITP projects should be expedited and placed in-service
sooner than the projects scheduled in-service date
- The Voltage stability analysis shows that renewable penetration
levels are approaching current limits
- All N-1 constraints were resolved, albeit with substantial
curtailments
- Ramping analysis indicates that in general, SPP has enough
ramping capability to sustain 60% penetration

Plan For Summer Assessment
- Similar to 2015/2016 Winter Assessment
– Thermal and voltage analysis – June 1st through September 30th – 2 models per week with outages
- Sunday & Wednesday
- Additional sensitivities as time permits
- Single Seasonal Model
- Includes all outages lasting longer than designated time threshold
- Used by other ISO/RTO
- Transfer Limit Analysis
- Major corridors
- PV Screening/Analysis
- Test only a few incremental transfer points
- Worst violation limits studied in more detail
- Loss of major gas pipeline
- Additional contingencies in N-1 analysis
Operations Season Assessment Task Force
- Updating our process going forward
– How often? – What sensitives? – Initial input by members? – Feedback/result mitigation by members?
What are the primary reliability concerns we must prepare for with more non-synchronous generation and less conventional generation?
Emergency Operating Plan (EOP) Overview
Types of Alerts
In order of severity:
Severe Weather Alert Conservative Operations Notification Energy Emergency Alert (EEA) (EEA1, EEA2, EEA 3)
Image: web.distran.com
Goal of Alert System
SPP’s Alert System
Provides SPP timely info:
- For evaluation
- Not readily available
via other methods Provides stakeholders ways to heighten awareness and provide direction
Which season tends to affect your operations the most?
Severe Weather Alerts
Section 9.2
Severe (Hot) Weather Pattern
- Weather forecasts
identify increased likelihood of extreme heat in the SPP BA
- Studies indicate
normal operations should not lead to insufficient BA capacity for affected period
46
Do you have a plan for updating your resource offers based upon anticipated fuel supply issues for the upcoming season?
Conservative Operations
Section 9.1
Condition Indications
Potential for: Forward-looking studies indicate normal operations could likely lead to increased risk of sufficient BA capacity for affected period
Stranded capacity due to transmission outages Unexpected resource outages
Image: mrtremblaycambridge.weebly.com
Conservative Operations
Assess situation Determine need to enter into Conservative Operations Issue notification to MPs
SPP Actions
SPP will identify: Period in which situation is expected to last Expected MP actions
Conservative Operations
Conditions are such, or expected to be such, that some extraordinary measures may be necessary to maintain RELIABLE operations
EARLY committal
- f Resources
UPDAT ATE! E! Additional UPDATES (as needed) BRIDGING of Resources
KEEP GOING
Delay/Postpone Outages (if possible)
Conservative Operations
Environment in which SPP is operating to/with:
- A. Conservative transfer limits values
- B. Selected double-contingencies
- C. Greater unit commitment notification timeframes
- D. Increased Operating Reserve requirements
E. Increased reliability Margin F. Timely coordination calls
MP Actions
Resource Offers cannot reflect some conditions SPP needs to know
What fuel types are most vulnerable to supply issues in your area?
Conservative Operations Alert
Who gets Alerts?
- MP email list
- Generation Operator
(GOP) RC email list
- TOP RC email list
- Neighboring BAs
and RCs
Conservative Operations Alert
Mechanisms for Alerts
- Emails
