Cycle 4 Survey Update

• There were varying degrees of response to the Cycle 4 Survey

– QSEs with Resources and TDSPs had 100% response to the Cycle 4 Survey

– 84% of QSEs have responded to the survey (up from 72% initially)

– 73% of LSEs have responded to the survey (up from 67% initially)

• This limited response is driving several metrics to red

– QSEs without Resources are red for MP1, MP12, and MP13

– LSEs are red for MP19

• ERCOT Account Managers will continue their outreach efforts to MPs who were non-responsive to the Cycle 4 Survey or who reported negative answers

• The survey will remain open through August 15th

• Updates to the Cycle 4 Survey can be submitted using the excel form found on the metrics website (same process as previous surveys)
