Urgent: No
Sections: Appendix 10
Description: This Verifiable Cost Manual Revision Request (VCMRR) adds a procedure to Appendix 10 for setting the variables used in the Mitigated Offer Cap (MOC) for hydro Generation Resources: setting Variable O&M (VOM) to the Real-Time System-Wide Offer Cap (RTSWCAP) and the incremental heat rate value to zero. These settings ensure that the MOC for such Resources is at least equal to or greater than the RTSWCAP.
Reason: ERCOT Board/PUCT Directive
