Once the replication system completed processing the data sets that caused the delays in processing last week, the backlog in replication of data to the data warehouse continued to decrease and publication of data extracts has now resumed to normal levels. ERCOT is closely monitoring the replication system and will continue working with its vendor to identify the root cause of the issue. Further updates on these efforts as well as steps taken to mitigate the risk of reoccurrence will be reported at the appropriate stakeholder forums in January.
