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…
The Gist ERCOT produces network models based on information contained in the ERCOT model database and the outage scheduler. When transmission entities upgrade lines they often have to lower the rating of the lines while they work on the upgrade. Occasionally the transmission entities enter the transmission downgrade into the network model but do…

The Gist NPRR863 put the concepts of ERCOT Contingent Reserve Service (ECRS) and Fast Frequency Response (FFR, a subset of Responsive Reserve Service) into the ERCOT protocols, but was not implemented immediately. This project implements parts related to FFR. The main issue with this project, and why it is a separate topic, is that it…
The Gist ERCOT produces the LTLF once a year in January with forecasts of energy usage and peak demand for the next ten years. In 2022, for the first time, ERCOT included a solar rooftop component in the forecast. The goal for 2023 is to include an electric vehicle component.. Important Actions 1/12/22 ERCOT presents…
