ACTION REQUIRED:  QSEs that represent Generation Resources and Transmission Operators are to confirm their participation by sending an email to John Jarmon ([log in to unmask]) by August 7, 2015, that includes the following required information:

·         Your company’s Drill Coordinator and his/her phone number.

·         The phone number of the site from which you intend to run your Drill. These numbers will be assembled into one phone list to be used by all Drill participants, in order to facilitate inter-communication.

·         A copy of your training plan. Your plan will be forwarded to the Texas Reliability Entity (TRE).

For compliance purposes, it will be necessary to document your company’s participation.  Drill logs, attendance records, and a comprehensive training plan will be used to meet these requirements.  Your company is required to develop its own additional in-house Drill scenarios, which should include coordination and participation with neighboring TOs and QSEs.  Companies should also conduct a post-mortem critique immediately following the Drill, and apply this time toward ERCOT’s 32-hour reliability training requirement.  Finally, we would encourage the senior management of all companies to participate in the Drill.

CONTACT:  If you have any questions, please contact your ERCOT Account Manager. You may also call the general ERCOT Client Services phone number at (512) 248-3900 or contact ERCOT Client Services via email at [log in to unmask].
