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
7
Minimum Run Time• A Resource’s 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 MP’s 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
8
Maximum Run Time• A Resource’s 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 MP’s 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 resource’s physical min down time begins when the resource is
de-synchronized and ends when the resource is physically able to synchronize again. • The MP’s 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 is
evaluated by SCUC for commitment purposes

Resource Offer Commitment ParametersStart-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 resource’s 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 resource’s 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-Intermediate Time Example
If the Resource’s De-Commit Time is 10:00 AM, the Intermediate Start-Up Offer price would apply for Resource commitments between 4:00 PM and 8:00 PM. The Hot Start-Up Offer price would apply for Resource commitments prior to 4:00PM.

Resource Offer Commitment ParametersSummary•The MP’s submitted Min Run Time should be the Resource’s physical min run time minus the Sync-to-Min time and Min-to-Off time
•The MP’s submitted Max Run Time should be the Resource’s physical max run time minus the Sync-to-Min time and Min-to-Off time
•The MP’s submitted Min Down Time should be equal to the physical min down time.
•The MP’s submitted time-related start-up parameters should be equal to the physical start-up time plus Sync-to-Min and Min-to-Off Time.
