Prior to the start of the drill, did you have the external phone lists you needed? Also describe any problems with phones, fax, emails, radios, etc. All participants agreed that all the contact numbers for the drill were correct and provided to them in a timely manner. There were minor issues with the Hotline calls. A few participants stated issues with static. ERCOT operators re-initiated the calls to ensure all participants received the messages. This did not cause any major issues for any of the participants.

8. ERCOT Recommendations For Future Drills

9. 9 Hurricane Drill 2014 Participants utilize Coordinators that are not shift workers. Coordinator’s disseminate all information supplied by ERCOT to all personnel scheduled to participate in the drill (have fully informed backups) For the drill to be meaningful for all participants, communication with ERCOT regarding simulator access is essential (please respond to emails requesting you to contact the ERCOT Coordinator for user name, password, and test dates for accessing the simulator). Market Participants are welcome to submit in-house scenarios for each event. ERCOT will evaluate all requests and incorporate as many as possible. Participant RSVPs and information needs to be returned to ERCOT no later than the scheduled dates. ERCOT will develop more detailed training material for use of the simulator.
