663NPRR Ancillary Service Insufficiency Actions This Nodal Protocol Revision Request NPRR specifies the actions ERCOT will take to ensure sufficient Ancillary Service capacity exists in the event that ERCOT is unable to procure enough Ancillary Service capacity to meet its Ancillary Service Plan through the DayAhead Market DAM In summary Supplementary Ancillary Service Market SASM and Hourly Reliability Unit Commitment HRUC will be used and in the event that Ancillary Service is still insufficient Ancillary Service will be assigned to Qualified Scheduling Entities QSEs with Generation Resources based on available capacity. 708NPRR . Clarifying ERCOT Actions During Energy Emergency Alerts. . This Nodal Protocol Revision Request (NPRR) revises the Energy Emergency steps to include concepts discussed during the 4/2/15 Energy Emergency Alert (EEA) workshop # 3 which will improve the management of EEA. Specifically, this NPRR explicitly adds the ability for operators to consider whether sufficient Resources are available to recover reserves within an acceptable timeframe following a disturbance before declaring an EEA; separates and clarifies the triggers for entering each step of the EEA plan from the operational goals while operating within each level of EEA; and formalizes an amount of Physical Responsive Capacity (PRC) for operators to target when determining Load shed amounts in EEA Level 3. NPRR654 . Discontinue Ancillary Service Requirement Methodology Assessment Report. . This Nodal Protocol Revision Request (NPRR) proposes the discontinuation of the posting requirement for the Ancillary Service Requirement Methodology Assessment Report, ERCOT Market Information List . 696NPRR . Price Correction Process Following a SCED Failure. .  This Nodal Protocol Revision Request (NPRR) establishes a price correction policy which uses the last good price for Settlement until ERCOT no longer requires manual action to stabilize the system following a SCED failure.  ERCOT provides notice to Market Participants of the occurrence of a SCED failure by declaring a Watch in accordance with paragraph (1) of Section 6.5.9.2.  Once the system has stabilized following a SCED failure and ERCOT no longer requires manual intervention, ERCOT will cancel the Watch in accordance with paragraph (4) of Section 6.5.9.2.  By correcting prices for Settlement Intervals corresponding to the active Watch period, Market Participants will have transparency to known prices which reflect the last good SCED execution. .
