By two hours before the close of the PX Day-Ahead Market on the day ahead of the Trading Day, the ISO will notify SCs of the Energy Requirements from any Reliability Must-Run Units which the ISO requires to run in the Trading Day, except in those instances where a Reliability Must-Run Unit requires more than one day’s notice, in which case the ISO may notify the applicable SC more than one day in advance of the Trading Day;
SP 3.2.1.2	By One Hour Before Close of the PX Day-Ahead Market, One Day Ahead
By one hour before the close of the PX Day-Ahead Market on the day prior to the Trading Day, SCs that have been notified that a Reliability Must-Run Unit is required to run in the Trading Day will inform the ISO whether the RMR Owner will take payment from the market or under the RMR Contract.
SP 1.1.2	By 6:00 am, One Day Ahead

SP 1.1.4	By 8:00 am, One Day Ahead
By 8:00 am on the day ahead of the Trading Day (for example, by 8:00 am on Tuesday for the Wednesday Trading Day), and for each Settlement Period of that Trading Day, Firm Transmission Rights owners will notify the ISO, via the Secondary Registration System or other means established by the ISO, of any transaction of Firm Transmission Rights and of any changes in SCs' rights to schedule the use of Firm Transmission Rights at particular Inter-Zonal Interfaces.

(f)	the ISO will validate (in accordance with the SBP) all SC submitted schedules for self-provided Ancillary Services, Inter-Scheduling Coordinator Ancillary Service Trades, and Ancillary Services bids which were part of their Preferred Day-Ahead Schedules;
(g)	the ISO will validate (in accordance with the SBP) all contract usage templates received from SCs for scheduled uses of Existing Contract rights and Firm Transmission Rights;

(k)	the ISO will validate that all SC submitted Preferred Hour-Ahead Schedules are compatible with the RMR requirements of which SCs were notified for that Trading Day and with the SCs’ elected option for delivering the required Energy.
SP 3.3.1.1	Pre-validation
At 10 minutes prior to the deadline for submittal of the Preferred Hour-Ahead Schedules, Adjustment Bids, schedules for self-provided Ancillary Services, Inter-Scheduling Coordinator Ancillary Service Trades, and Ancillary Services bids (the “submittal”), the ISO shall conduct a pre-validation of the stage two validation described in the SBP.  The purpose of this is to allow the SCs, particularly those involved in the Inter-Scheduling Coordinator Energy Trades, to identify and resolve any validation problems.  The ISO will immediately communicate the results of the pre-validation of each SC’s submittal to that SC via WEnet.

SP 3.3.1.2	Invalidation
Except with respect to invalidated contract usage associated with Existing Contract rights or Firm Transmission Rights, invalidation of the submittal results in rejection of the submittal.  SCs will be notified of any invalid contract usage via an invalidated contract usage template issued, via the WEnet, by the ISO.  Invalidation of contract usage will not cause the rejection of the SC's submittal; instead, invalid contract usage will be treated as new firm uses of ISO transmission service without the priorities and protections afforded the scheduled use of Existing Contract rights and Firm Transmission Rights.  SCs may check at any time prior to two hours ahead of the relevant Settlement Period whether or not their submittals will pass the ISO’s validation checks (which are undertaken at two hours ahead of the Settlement Period).  It is the responsibility of SCs to perform such checks since Preferred Hour-Ahead Schedules, Adjustment Bids, schedules of self-provided Ancillary Services, Inter-Scheduling Coordinator Ancillary Service Trades and Ancillary Services bids which are invalidated cannot be resubmitted for the Hour-Ahead Market after two hours ahead of the relevant Settlement Period.  The ISO will immediately communicate the results of each SC’s two hour ahead validation to that SC via WEnet.  If the usage or sum of the usages associated with an Existing Transmission Contract results in the contract being over-scheduled, the usages will be adjusted such that a usage in excess of the ETC rights will be considered a New Firm Use (NFU) and will be exposed to Congestion charges. 
Units it requires to become the subject of a Reliability Must-Run Contract which had not previously been so contracted to the ISO.  None of the Generating Units owned by Local Publicly Owned Electric Utilities are planned to be designated as Reliability Must-Run Units by the ISO as of the ISO Operations Date but are expected to be operated in such a way as to maintain the safe and reliable operation of the interconnected transmission system comprising the ISO Control Area.  However, in the future, Local Publicly Owned Electric Utilities may contract with the ISO to provide Reliability Must-Run Generation.
SP 1.1.7	Annual Reliability Must-Run Forecast - Technical Studies
The ISO will perform off-line technical studies, adopt existing procedures developed by PTOs and/or develop new operating procedures to identify the Reliability Must-Run requirements for various levels of system Demand.
SP 1.2	Designation of Generating Unit as Reliability Must-Run
The ISO will have the right at any time based upon ISO Controlled Grid technical analyses and studies to designate or disqualify a Generating Unit as a Reliability Must-Run Unit.
SP 1.3	Scheduling of Reliability Must-Run Generation
The ISO will notify SCs of any Reliability Must-Run Units which the ISO requires to run during a Trading Day no later than two hours before the close of the PX Day-Ahead Market for that Trading Day, as described in SP 3.2.1.1
