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. Further details about the Resettlement Statement are included in the table below: Affected Operating Day February 8, 2011 Description of reason for Resettlement ERCOT revenue neutrality Affected Settlement Charge Types DACRRSAMT, DACRRSRTAMT Publication Date of Previous Settlement Statement February 10, 2011 Publication Date of Resettlement Statement March 9, 2011 Invoice Date of Resettlement Statement March 9, 2011 Resettled Charge Types Resettlement Amount Day-Ahead CRR Shortfall Amount per owner (DACRRSAMT) $642,979.07 Day-Ahead CRR Short Ratio Real-Time Amount per owner (DACRRSRTAMT) $109,032.56 CONTACT: If you have any questions, please contact your ERCOT Account Manager.
