35 Balancing Authority ACE Limit Proof-of-Concept Field Trial Examples of circumstances when BAAL was exceeded and actions taken if appropriate On a monthly basis, each Balancing Authority will review its performance for the prior month and identify any periods where the ACE exceeded the low BAAL ( BAAL Low ), the high BAAL ( BAAL High ), the low ATL or high ATL for more than 30 consecutive clock-minutes. To help the RBCSDT gain a better understanding of the circumstances that all Balancing Authorities may be faced while operating under BAL-007, each Balancing Authority will provide a brief explanation of the circumstances related to any periods where the duration of consecutive clock-minutes exceeded 30 minutes. In the event that no period exceeded 30 minutes in the prior month, but the longest duration exceeded 25 minutes, the Balancing Authority will provide a brief explanation of the circumstances related to that longest-duration event. Limit Exceeded (Enter one of the following: BAAL high, BAAL low, ATL high, ATL low) Clock-minute of ACE exceeding the BAAL or ATL (mm/dd/yy hh:mm) Clock-minute of ACE returning within the BAAL or ATL (mm/dd/yy hh:mm) Time Zone Total duration of ACE exceeding the BAAL or ATL (minutes) Event associated with a DCS- Reportable Event? (0=No, 1=Yes) Event associated with a resource loss other than a DCS- Reportable Event? (0=No, 1=Yes) Brief explanation of circumstances and notable actions taken if applicable BAAL Low 03/06/ :11 03/06/ :39 MST 0: Wind speed decreased intra-hour causing generation to decrease with frequency trending below 60 Hz. Forecast did not indicate an decrease in wind speed. Operator deployed inc resources, but wind speed continued to fall, so operator initiated curtailment of G-NF schedules to return ACE to zero. BAAL Low 03/31/ :03 03/31/ :31 MST 0: Wind stopped, wind generation ceased to exist
