Commitment Reminders

• DA Market, DA RUC, and ID RUC processes use the
  Current Operating Plan (COP) for determining if a
  Resource has satisfied submitted Commitment
  Parameters
• Commit Times are communicated as Start or
  Stop notifications
• Indicates when SPP expects the resource to be at
  minimum
• PLEASE NOTE During SMT, the COP True-Up process
  is performed after DA RUC and run every two hours
  throughout an OD
• DA Market will be affected by EIS Market
  commitments
• Example Resource with Max Run Time of 24 hours
  but shows as online for a week due COP True Up
• DA Market will decommit the resource

Resource Offer Commitment Parameters

• Minimum Run Time

• A Resources physical min run time begins when
  the resource is synchronized and is the amount of
  time a resource must remain synchronized. (Sync
  to Off)
• The MPs submitted Min Run Time used by the
  Market should be the physical min run time minus
  the Sync-to-Min time and Min-to-Off time
• SCUC does NOT consider Sync-to-Min and Min-to-Off
  when evaluating Min Run Time for commitment
  purposes

Resource Offer Commitment Parameters

• Maximum Run Time

• A Resources physical max run time begins when
  the resource is synchronized but has a limit for
  how long it can remain synchronized. (Sync to
  Off)
• The MPs submitted Max Run Time used by the
  market should be the physical max run time minus
  the Sync-to-Min time and Min-to-Off time
• SCUC does NOT consider Sync-to-Min and Min-to-Off
  when evaluating Max Run Time for commitment
  purposes

Resource Offer Commitment Parameters

• Minimum Down Time

• A resources physical min down time begins when
  the resource is de-synchronized and ends when
  the resource is physically able to synchronize
  again.
• The MPs submitted Min Down Time used by the
  market should be the physical
• min down time of the resource.
  (completely offline)
• SCUC automatically adds Sync-to-Min and
  Min-to-Off time to the value entered for Min
  Down Time
• This sum represents the effective Min Down
  Time, which isevaluated by SCUC for commitment
  purposes

Resource Offer Commitment Parameters

• Start-Up Parameters
• In the Start-Up Offer, MPs submit a hot,
  intermediate and cold start-up price
• In the Resource Offer, MPs submit two
  time-related parameters
• Hot-to-Cold Time
• Hot-to-Intermediate Time
• These parameters are used to determine which
  start-up price is applied

Resource Offer Commitment Parameters

• Hot-to-Cold Time
• A resources physical hot-to-cold Time begins
  when the resource is de-synchronized and
  represents the amount of time required before the
  next synchronization after which a cold start-up
  offer will apply.
• The MP-submitted Hot-to-Cold Time should be equal
  to the sum of the physical hot-to-cold time, the
  Sync-To-Min Time and the Min-To-Off Time
• No programmatic summing of parameters is
  performed in determining start-up times for
  applying start-up price

Resource Offer Commitment Parameters

• Hot-to-Intermediate Time
• A resources physical hot-to-intermediate Time
  begins when the resource is de-synchronized and
  represents the amount of time required before the
  next synchronization after which an intermediate
  start-up offer will apply.
• The MP-submitted Hot-to-Intermediate Time should
  be equal to the sum of the physical
  Hot-To-Intermediate time, the Sync-To-Min Time
  and the Min-To-Off Time
• No programmatic summing of parameters is
  performed in determining start-up times for
  applying start-up price

• Hot-To-Cold Time Example
• If the Resources De-Commit Time is 1000 AM, the
  Cold Start-Up Offer price would apply for
  Resource commitments after 800 PM.

Markets UI Resource A (MP-submitted) Hot-to-Cold
Start-Up Time 10 hours

• Hot-To-Intermediate Time Example
• If the Resources De-Commit Time is 1000 AM, the
  Intermediate Start-Up Offer price would apply for
  Resource commitments between 400 PM and 800 PM.
  The Hot Start-Up Offer price would apply for
  Resource commitments prior to 400PM.

Resource A physical hot-to-intermediate time 4
hours Sync-to-Min Time 1 hour Min-to-Off Time 1
hour
Markets UI Resource A (MP-submitted) Hot-to-Inte
rmediate Time 6 hours

Resource Offer Commitment Parameters

• Summary
• The MPs submitted Min Run Time should be the
  Resources physical min run time minus the
  Sync-to-Min time and Min-to-Off time
• The MPs submitted Max Run Time should be the
  Resources physical max run time minus the
  Sync-to-Min time and Min-to-Off time
• The MPs submitted Min Down Time should be equal
  to the physical min down time.
• The MPs submitted time-related start-up
  parameters should be equal to the physical
  start-up time plus Sync-to-Min and Min-to-Off
  Time.
• These parameters are used to determine which
  Start-Up price to use
