The Gist NPRR930 clarifies the process that ERCOT can use to delay or cancel outages.  It first has to post an Advance Action Notice (AAN) a minimum of 24 hours before adjusting a resource’s outage schedule.  Further, resources can change their outage types to Forced to prevent ERCOT from adjusting their outage schedule.  Finally if…

The Gist NPRR1106 allows ERCOT to deploy ERS when Physical Responsive Capacity (PRC) falls below 3000MW and is projected to stay below 3000MW for at least 30 minutes.  This is a significant change to the ERS product, as previously ERS was only deployed in emergency situations (PRC < 2300MW) which were very rare. Important Actions…

The Gist NPRR1101 was filed by ERCOT as a response to complaints made by generators to NPRR1093 (allow loads to provide NonSpin).  It directs ERCOT to create ~500MW buckets of NonSpin, randomly composed of load resources and off-line generation resources.  Market consensus was that this fixed the perceived unfairness of deploying generators carrying NonSpin before…

The Gist NPRR1107 sets out how generators are to pay for all the weatherization inspections for the first year of inspections.  The Public Utility Commission required that generators pay for all the costs that ERCOT incurs for the increased weatherization inspections that they are doing in the wake of Winter Storm Uri.  The original NPRR…

The Gist NPRR1084 was filed by ERCOT in response to concerns regarding generation outages during Winter Storm Uri.  It originally would require the entry of all forced outages and derates into the outage scheduler, regardless of the size or duration of the outage or derate within an hour of the start of the outage.  It…

The Gist NPRR1105 allows ERCOT to instruct TDSPs to implement voltage reduction prior to declaring EEA1 (previously ERCOT could not do so until EEA2).  ERCOT was instructed to file this NPRR by the PUC Commissioners.  There was much discussion about whether it was a good idea to deploy Voltage Reduction early in an emergency, as…

The Gist In the wake of the Green Hat scandal in PJM, ERCOT decided to strengthen its entry requirements and review of market participants with this NPRR.  It creates a new background check and perform more rigorous credit scrutiny of market participants, particularly changing its creditworthiness assessment.  It currently needs to be adjusted to account…

The Gist NPRR1098 requires new DC Ties to provide reactive support similar to that provided by generators.

The Gist NPRR1099 allows ERCOT to move Resource Nodes when Points of Interconnection change or when resources retire.  There was initially some pushback due to the concerns that changing resource nodes can greatly impact the value of associated CRRs, but those were assuaged by ERCOT’s 11/24/21 comments (to NPRR1099 and OBDR034) which limited ERCOT’s ability…

The Gist Originally implemented as an interruptible load service (and called ERCOT Interruptible Load Service -EILS-,  ERS is an emergency service that ERCOT can deploy when Physical Responsive Capability (PRC) drops below 3000 MW (Previously ERS was deployed during EEA1 and 2, but NPRR1106 changed this to PRC<3000MW).  Providers of ERS can either be loads…
