SCED Issues

1. EMS Hardware insufficient for user base and functionality– INF prioritized production hardware for EMS – will use for EMS 3B

2. SCADA mapping resulted in all Combined Cycles MW telemetry levels set to 0– Corrected in SCADA load on Friday 12/14; still needs to be verified

3. Interface table for Constraint Names incorrect so SCED is not able to process constraint names & shift factors

4. MPs sending Incorrect values for CC configuration causes SCED failure– Working with EMS team to implement data check and MPs to send valid

configuration values5. MPs sending HSL < LSL resulting in SCED failure

– Working with MPs to resolve and adding validation in EMS to set LSL = HSL when telemeter HSL<LSL

6. MPs sending resource status of off when actual telemeter MW output is > 0– SCED sets basepoint = 0

7. MPs sending invalid resource status (e.g. 050)– SCED ignores the unit

8. DC TIE Telemetry missing and DC Tie calculation not working– Adding telemetry and EMS team resolving calculation function

Joint effort between ERCOT and MPs to resolve most of these will enable reasonableness declaration
