SHORT DESCRIPTION:  Real-Time Market Resettlement for Operating Day July 7, 2016

INTENDED AUDIENCE:  QSE and CRRAH Settlement Personnel

DAY AFFECTED:  July 7, 2016

LONG DESCRIPTION:  On July 7, 2016, ERCOT experienced issues with the Energy Management System (EMS), which caused corrupt data (including Emergency Base Point data) to be passed through downstream systems including the Settlements System. ERCOT has completed corrections to the Emergency Operations Settlement for the outage period on July 7, 2016 (i.e., intervals 11:45 - 13:30) and used the Real-Time Metered Generation (RTMG) in place of Emergency Base Point data under ERCOT Protocols Section 6.6.9(4).
