PUCT's first five year review of the ERCOT system-wide offer caps closed to comment on September 17th
The Public Utility Commission of Texas has opened Project 59550, the quinquennial review of the system-wide offer cap programs under 16 TAC Section 25.509(d). Commission staff filed a memorandum on August 20th, 2026 asking interested parties to answer questions about whether the caps and the emergency pricing program should change. The memorandum states that calendar year 2026 marks the first review period for these programs. It also states that ERCOT has never activated the emergency pricing program since it was adopted. Comments were due by September 17th, 2026, and the project's filing index now stands at 20 filings.
How to take part
Anyone may file comments under control number 59550 through the commission's Interchange filer, or send a paper copy to Central Records in Austin. No lawyer and no standing are required. The memorandum asks each filer to attach a standalone executive summary as the last page. The September 17th, 2026 deadline has passed. The filings already made stay open to read in the Interchange under control number 59550.
