(a)	adjust interchange transaction schedules (ITSs) as required under Existing Contracts in accordance with the procedures in the SBP and the SP for the management of Existing Contracts;
(b)	adjust ITSs as required by changes in transfer capability of transmission paths occurring after close of the Hour-Ahead Market; and
(c)	agree on ITS changes with adjacent Control Area Operators.
DP 7.3	Supplemental Energy Bids
Supplemental Energy bids may be submitted to the ISO no later than thirty (30) minutes prior to the beginning of the Settlement Period in accordance with the format and content requirements of the SBP.  These Supplemental Energy bids cannot be withdrawn after thirty (30) minutes prior to the beginning of the Settlement Period.  The ISO may Dispatch the associated resource at any time during the Settlement Period.
DP 7.4	Intra-Zonal Congestion Management
In the hour prior to the beginning of the Settlement Period the ISO may adjust SCs’ Final Schedules to alleviate Intra-Zonal Congestion.  Except in those instances where the ISO calls Reliabiity Must-Run Units as provided in Section 5.2 of the ISO Tariff, the ISO will adjust resources in accordance with DP 8.4 and DP 8.5.

($/MWh) or the Curtailable Demand located within the Zone (or the Interconnection schedule in a Control Area adjacent to the Zone) with a non-zero capacity remaining to reduce which has the lowest Demand reduction bid price.
DP 8.3.3	Selection of Generating Unit to Reduce Generation
Where the ISO determines that it is necessary to reduce Generation in a Zone in order to relieve Inter-Zonal Congestion, the ISO shall select from the merit order stack the Generating Unit within the Zone with a non-zero capacity remaining to decrement which has the highest decremental bid price.
DP 8.4	Intra-Zonal Congestion
Except as provided in Section 5.2 of the ISO Tariff, in the event of Intra-Zonal Congestion in real time, the ISO shall adjust Generating Units and Curtailable Demands (or Interconnection schedules of System Resources in the Control Areas) to alleviate the constraints, using available Adjustment Bids and Imbalance Energy bids based on their effectiveness and in merit order.
DP 8.5	Additional Congestion Relief
In the event that there are insufficient resources which provide financial bids to mitigate Inter-Zonal and Intra-Zonal Congestion, Final Schedules which do not rely on Existing Contracts will be adjusted in real time by allocating transmission capacity on a pro rata basis.  Final Schedules which rely on Existing Contracts will be adjusted in real time by allocating transmission capacity in accordance with the operating instructions submitted under SBP 3.3.   With respect to facilities financed with Local Furnishing Bonds the ISO shall adjust Final Schedules in real time in a fashion consistent with Section 2.1.3 and 7.1.6.3 of the ISO Tariff, Appendix B of the TCA, and Operating Procedures governing the use of such facilities.
