The Gist NPRR1081 was filed by ERCOT and the independent market monitor (IMM) as a response to the unexpectedly low prices (i.e. less than $9000/MWh) during the first day of Winter Storm Uri. The thought being that if firm load is being shed the prices should be set to the value of lost load (VOLL). …
The Gist ERCOT noticed that RegUp was being double counted in the regulation up component of Controllable Load Resources (CLRs). This resulted in overpayment to some QSEs (around $13k total). This NPRR fixes that double counting Important Actions 1/13/22 CNPRR1113 introduced to PRS and quickly passed on the combo ballot Reference NPRR1113 (ERCOT) Meeting Notes…
The Gist NPRR1109 Declares that recently (within the last three years) can reenter the ERCOT grid without a full set of interconnection studies if ERCOT feels it is appropriate and there have been no material changes to the resource since retirement. This was placed in the protocols on an urgent basis to allow a resource…
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…
