NOTICE DATE:  March 9, 2011
NOTICE TYPE:  W-A030911-01 Settlement
SHORT DESCRIPTION:  Notification of Day-Ahead Market Resettlement for Operating Day February 8, 2011
INTENDED AUDIENCE:  QSE and CRRAH Settlement Personnel
DAY AFFECTED:  Operating Day February 8, 2011
LONG DESCRIPTION:  ERCOT issued Real-Time Market (RTM) Settlement Point Price corrections for February 8, 2011, on February 9, 2011. The price corrections were accurately reflected in RTM Settlements for February 8, 2011. However, the corrected prices were not put into ERCOT's Settlement System until after Day-Ahead Market (DAM) Settlement for February 8, 2011, was complete. Therefore, the published DAM Statements and Invoices for Operating Day February 8, 2011, included CRR Shortfall Charges that were calculated using the incorrect Real-Time Settlement Point Prices. To ensure ERCOT remains revenue neutral after the Monthly Refunds to Short-Paid CRR Owners and the Monthly CRR Balancing Account Closure, ERCOT will resettle the DAM for Operating Day February 8, 2011.
