CRR Shortfalls Jim Galvin
CRR Shortfalls and Balancing Account • Nodal Market rules were designed to make all attempts to “make whole” CRR holders in the Day Ahead Market (DAM) • Market rules will create a short fall in a given hour for CRR holders when there are insufficient “Congestion Rents” collected • Congestion Rents fund the CRRs as well as CRRs that are paid to ERCOT (CRRs on the counter flow of congestion) • CRR Balancing Account (CRRBA) is funded in any hour that Congestion Rents exceed CRRs to be paid • At the end of each month, the CRRBA is utilized to “make whole” any CRR holders who were short paid in the month • After make whole, any funds remaining in the CRRBA are given back to Load Meeting Title (optional)
Balancing Account Components • Day Ahead Congestion Rent • Sum of all Day-Ahead Energy Purchase and Sales, RMR Day-Ahead Energy and Day Ahead to Real Time Obligation settlement • Day-Ahead CRR Credit Total (green elements from previous slide) DACRRCRTOT • Credits for Day-Ahead Obligations and Options including refund amounts and Day-Ahead Flow Gate Rights • Day-Ahead CRR Charge Total (red elements) DACRRCHTOT • Charges for Day-Ahead Obligations including refund charge Meeting Title (optional)
De-Rated CRRs • CRRs that have source-sink path where either the source or the sink are a resource are subject to de-rate • Source-sink pairs with resources can de-rate the Hedge Value of the CRR based on Shift Factors for the resource on the path constraint • Source-sink pairs that are Load Zone to Hub, Load Zone to Load Zone or Hub to Hub are not subject to de-rate • CRRs are fully funded; however, shortfalls based on lack of Congestion Rents will exist for CRR holders who are owed money in the settlement interval • De-rated CRRs with resource as source or sink are subject to both de-rate and shortfall Meeting Title (optional)
CRR Short Fall Estimate • The following slide will examine the estimated payout to Load from the Balancing Account and the CRR’s short paid due to under collection of Congestion Rents (under-funded Balancing Account) • Table represents Channel 1 data (Initial Settlement) and provides Nodal-to-Date view Meeting Title (optional)
