The Texas Public Utility Commission (PUC) is in the process of drafting a rule that will establish a formal procedure for market participants to request exemptions from ERCOT's reliability requirements. This initiative follows the approval of a change to ERCOT's Nodal Operating Guide, which introduced new voltage ride-through requirements for inverter-based resources. The proposed rule aims to facilitate appeals to the PUC regarding ERCOT's decisions, while ensuring that existing exemptions and unrelated protocols remain unaffected.

Additionally, the PUC's Division of Compliance and Enforcement is addressing around 130 violation findings related to entities that have failed to submit their emergency operations plans (EOPs) or annual updates. Following a directive to investigate non-compliant entities, DICE has identified a number of companies that have met compliance deadlines, and most cases have been resolved through corrective action plans. The focus remains on ensuring reliability over cost considerations in the evaluation of exemption requests.
