OD 9/18/2022 About $2.8M RENA was observed on OD 9/18. Most of the RENA was related to the DAM oversold on the RT constraints. DAM oversold on the RT constraints: There was about $1.3M DAM oversold on the RT constraint MWHI58: NUECES_WHITE_2_1 during OD 9/18. LDFs at a nearby PUN were the major contributor to the observed DAM oversold on this constraint, as the PUN net load changed significantly due to its resource outages. 5 PUBLIC
