  1. Report onLessons Learned – Hurricane RitaNovember 10, 2005 ROS Meeting Austin Control Center (MET Center)

  2. It is better to be missed than hit… • ERCOT was not significantly impacted by hurricane RITA. • ENTERGY was significantly impacted; and ERCOT is attempting to learn from their experience. • ERCOT does not yet have a response.

  3. ERCOT is able to setup and execute Block Load Transfer rapidly • ERCOT was able to quickly implement block load transfers within the market structure • Registration – Financial qualification was done quickly through picking an existing representative in ERCOT. We were able to push through the database in 1 day what normally takes 3-4 days. Registered delivery point as a new NOIE LSE. The LSE pointed to an existing QSE. Set EZID as a wholesale delivery point. Nothing went to MOS. • We are required by protocol to have metering at BLT’s– Centerpoint and TXU got meters installed and registered EZIDs at ERCOT very quickly.

  4. Backup Center activation • Several QSE’s/TDSP’s activated their emergency backup centers/plans. • Some QSE’s have backup centers • Some delegate another service provider to provide services • In general, this was successful. • One center did not successfully communicate during the storm period. • Storm impact was minimal

  5. Loss of Communications • ERCOT implemented a plan for loss of communications • ERCOT procured satellite telephones for the event. • It was not needed during this event

  6. ERCOT Can expect timely government action if needed • Actions: • Governor issued order suspending eminent domain requirements for temporary facilities • On 9/27 PUCT issued order suspending CCN requirements and allowing ERCOT TDSPs to extend service in area • DOE agreed to issue order maintaining ERCOT’s FERC exemption for these emergency connections

  7. ERCOT does NOT have an effective method of forecasting load in either Commercial or Operational systems • We should expect high UFE amounts on and around projected hurricanes landfall • We should expect high errors in the ERCOT operational load forecast.

  8. ERCOT has sent a list of questions to Entergy… • What did you learn from your experiences with hurricanes this summer? • What would you do differently when preparing for hurricanes in the future? • Do you have an existing emergency plan that deals with hurricanes? Can you share it? • Did you shut down plants in preparation for the storm?  Should you have? • What advice can you give us on how to prepare? • Should we have a special emergency plan for hurricane preparation? • Do you set distribution relays to one-shot near the coast? • Can you advise us on how to plan for fuel curtailments/issues? • Do you believe additional units should be gotten on line, or should we reduce the number of units online so we can get under the load? • What did you do with staff?  Did you put people in critical locations?
