SummaryRetail Activity• Overall Activity – Activity continues to follow recent trends. A Mass Transition occurred during February; 99.75% of the customer transitions were
complete within 2 days and all transitions were complete within 5 days.• Transaction Performance Measures – Generally good performance in February. One system issue did cause some measures to fall below the
98% target.• Advanced Metering – Over 2.4M ESIIDs are now settled using advanced meter data with around 99% having actual data available for initial
settlement.
Wholesale Activity • Settlements & Billing Performance – Perfect performance in February.• Settlement Dollars – Excluding the extreme weather event, the average dollars transacted were similar to prior months since go-live (around $7M).
The extreme weather days averaged around $65M with the highest day (2/2/11) at $190M.• Reliability Services – February RUC Make Whole Payments to generators were much higher than seen in prior months, but were offset by even
higher RUC Clawback Charges which resulted from the high prices on the cold weather days. • Capacity Services – due to the weather events, capacity service costs for February were substantially higher with the most dramatic increases in
Responsive Reserve and Non-Spinning Reserve.• Congestion Management – Due to the weather events, congestion payments for February were substantially higher than prior months, totaling over
$80M• Verifiable Costs – Approximately half of the available capacity is supported by approved verifiable costs.• DAM Resettlement - ERCOT resettled the DAM for 2/8/2011. The resettlement was necessary to achieve revenue neutrality in the Balancing
Account Closure process because of a procedure failure in ensuring that the 2/8 RTM Settlement Point Price corrections were used by the 2/8 DAM Settlements.
• Market Short-pay - Multiple RTM Invoice short-payments by Abacus Resources Energy LLC causing partial payments to the market. To-date, the total Abacus short-payment is in the amount of $731,420. The default uplift to the market will occur no earlier than September 2011.
• Market Extracts and Reports – Over 1.7M extracts/reports posted during February; over 15.6M extracts/reports downloaded• Disputes – Dispute volumes have increased somewhat but continue to be lower than anticipated.• REPs and QSEs Added/Terminated
– 1 new REPs – 3 terminated REP– 2 new QSEs – 1 terminated QSEs
