Executive Summary This special PRS was entirely focused on two NPRRs, NPRR1097(ERCOT forced outage report) and NPRR1120(Firm Fuel Supply Service).   The NPRR1097 discussion dealt with  whether the Resource Entity should be in the report (resolution = no) and what language to use to allow state governmental entities to see outage data right away during an…

Executive Summary A long TAC that got very interesting at the end.  There was a quick heads up on the upcoming cold weather event (ERCOT will most likely be okay, but will possibly procure more NonSpin and also requests that resources enter outages as soon as possible, particularly gas supply related outages and derates.) There…
