ERCOT Retail Outages and Transaction Processing Notices as of September 2004
Recap • ERCOT Client Services (Retail and Wholesale) continues to work with COPS (communications team) to make improvements to market notices. • At the Sept RMS meeting, ERCOT was requested to share additional information on duration. • Today we will share information about duration and a recommendation will be made for future reporting to RMS.
Durations and Effect on Metrics Reminder: NAESB outages, when ERCOT is not receiving inbound transactions, would be reflected in market metrics. The transactions are time stamped when received by NAESB. • An 814_04 response to an 814_03 would be an example of one that would be timed LONGER because of NAESB being down and could result in protocol non-compliance. • If a REP sends an 814_01, and ERCOT is not receiving, the clock hasn’t started NAESB outages, when ERCOT is not able to push transactions, then the clock is still running for the MP on the response transaction to ERCOT. • The 814_03 in the above example would be time stamped out by ERCOT and the clock would be running for the 814_04 back to ERCOT. Anytime ERCOT is holding transactions in the internal ERCOT systems it will be reflected in the metrics reported to the MP and PUCT and be on ERCOT’s time.
