Executive Summary PRS passed two contentious NPRRs (NPRR1096-battery duration for NonSpin and ECRS and NPRR1092-reduce RUC Offer Floor and remove Opt Out). There was a lot of discussion on the issues, but essentially no new views. NPRR1120(Firm Fuel Service) was discussed, and the Independent Market Monitor explained their comments (things that they would like to…
Executive Summary Today’s WMS meeting was dominated by two big debates; what should Firm Fuel Supply Service (FFSS) look like (lots of open questions listed below), and how much NonSpin and ECRS should batteries be able to carry (ERCOT is standing firm on 4 hours for NonSpin, 2 hours for ECRS). Other than that there…
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…
Executive Summary A long WMS meeting covered topics important to generators (NPRR1084- require outages for derates; NPRR1108- ERCOT to approve or deny all resource outages, possible RMR of resource owned transmission equipment), batteries (NPRR1100-Allow emergency microgridding, NPRR1096-battery duration for NonSpin and ECRS) and everyone connected to the grid (how do exceptional fuel costs affect mitigation,…

Notes Firm Fuel Service – the commission stated that they all agree…
Executive Summary The big topic today was nodal pricing of load resources. ERCOT (Sai Moorty) presented a deck outlining the issues that he sees with giving nodal prices to load resources and where ERCOT stands on the issue currently. ERCOT is currently focusing on implementing this for large single site resources. This effort will not…
Executive Summary Two big topics dominated the discussion at today’s CWG/MCWG meeting. First up was NPRR1112 (eliminating unsecured credit). Public power came out strongly against this NPRR. The need was hotly debated, and it was tabled, probably to be amended to be a lowering of the unsecured credit cap (currently at $50M). Stay tuned for…
Executive Summary Today’s Wholesale Market Working Group (WMWG) meeting focused on six main topics: NPRR1084 (Require outage reports within a half hour if over 2%), implementation of the new HCAP, a NERC presentation on the Uri outage, NPRR1100(ability to microgrid with nearby batteries if there is a transmission outage), NPRR1108 (ERCOT to not allow planned…
Executive Summary A quick, painless Protocol Revision Subcommittee (PRS) meeting. Troy gave his usual update on project statuses, still with no implementation date for FFR Advancement, which changes the ERCOT interface. Mark Ruane gave an update on securitization – a webpage with everything you need to know is at https://www.ercot.com/about/news/securitization . Three non-exciting NPRRs passed…
