On October 28, 2011, ERCOT issued Notice W-A100311-02 indicating that its initial determination required further analysis to determine if the Resources
would be needed for Reliability Must-Run (RMR) Service and that a final determination would be issued by December 7, 2011.
Due to recent changes on the ERCOT System that impact the RMR analysis, and due to the receipt of additional data from the impacted Transmission Service
