ERCOT stakeholders have approved a protocol change (NPRR1229) aimed at compensating market participants when a generator is tripped due to a constrained management plan or ERCOT-directed instruction. This decision, made during the Technical Advisory Committee's April 23 meeting, faced opposition from consumer groups who argued that it shifts costs away from direct assignment of congestion costs. Despite the objections, the measure passed with a vote of 20-8, highlighting a divide between consumer interests and those advocating for the change.

Additionally, the TAC discussed the transition of the Large Flexible Load Task Force into the Large Load Working Group, which will focus on integrating large loads into the ERCOT system. The committee also endorsed a $119 million project by Oncor to upgrade a transmission line in West Texas, addressing reliability issues. Other items on the agenda included changes to the requirements for Mexico's state-owned electric utility and the implementation of a new authentication flow for certain ERCOT applications.
