Grid operator and reliability

ERCOT. Most of Texas is ERCOT; the Panhandle and eastern edges sit in SPP and MISO, and El Paso is on the Western grid.

NERC area Texas RE-ERCOT: anticipated reserve margin 28.2% for summer 2026, against its reference level of 13.75% (+14.4 points). NERC rates the area elevated risk; later years: High from 2029.

Recent public decisions

• September 18, 2026, Public Utility Commission of Texas: Large load interconnection standards adopted under Senate Bill 6. The Commission adopts new 16 TAC 25.194 under Project No. 58481, implementing PURA 37.0561 as enacted by Senate Bill 6, effective October 8, 2026. The rule applies to a large load customer not energized by that date that seeks a new interconnection of 75 MW or more at a single site, certain expansions, or co-location with a generation resource. Before being included in an ERCOT interconnection study, the customer must sign an intermediate agreement, make required disclosures, and post financial security of $50,000 per MW of requested peak demand. Under the later standard interconnection agreement, the security is the greater of $50,000 per MW of contracted peak demand or the costs allocated for system upgrades. The preamble leaves parts of the standard large load interconnection agreement, including the timeline for returning security, to a separate rulemaking, and says transmission cost recovery will be addressed in Project No. 58000. Texas Register, October 2, 2026, Adopted Rules, 16 TAC 25.194 (TRD-202604027)
• September 14, 2026, ERCOT: Data center energizations paused pending state verification and audit. ERCOT's Batch Zero update to its Board says Governor Abbott's August 3, 2026 directive asked the Commission and ERCOT to complete a comprehensive verification and audit of data centers in the interconnection process. In response, ERCOT paused the Batch Zero study process and paused approvals to energize data centers and crypto mining facilities of 75 MW or more. Conditional classifications sent to transmission providers on September 3, 2026 included 204 projects (66.4 GW) as base load and 158 projects as studied load, and excluded 373 projects (302.2 GW). Final inclusion will follow the verification and audit, to be provided in December. ERCOT says it is still determining the impact on the study timeline, which PGRR 145 originally set to finish by April 9, 2027. The item was for information only, with no Board action requested. ERCOT Board of Directors, Item 14: Batch Zero Update (September 14-15, 2026)
• August 3, 2026, ERCOT: Batch Zero classification delayed after Governor's letter. ERCOT says it received a letter from Governor Greg Abbott directing it to conduct a verification process before advancing any data center large loads. As a result, it will not notify distribution and transmission service providers by August 7, 2026 of how any large load is classified in the Batch Zero Interconnection Study. Ahead of the Commission's August 20, 2026 open meeting, it will file a request for a good cause exception to the Batch Zero timelines and processes in its Planning Guide. The notice does not mention energization approvals; it says ERCOT will consult with the Commission on next steps. ERCOT Market Notice M-A080326-01, Update Regarding Batch Zero Timelines and Processes
• May 18, 2026, ERCOT: ERCOT asks to adjust its 2026 long-term load forecast before using it. ERCOT filed with the Commission a proposal to adjust its 2026 preliminary long-term load forecast before using it in transmission planning and resource adequacy studies, including the 2026 Triennial Reliability Assessment. The preliminary forecast projects peak load of 278,003 MW in 2029 and 367,790 MW in 2032. ERCOT offers two options: an adjustment based on how many computational large loads actually energized when expected, or use of the Batch Zero load forecast. It recommends the Batch Zero option, which it says would not be finalized until mid-August 2026. The notice is a proposal; the Commission was scheduled to consider it at its June 18, 2026 open meeting, in Project No. 59772.

What this page cannot tell you about a bill

In the competitive retail areas of the ERCOT region, a home buys electricity from a retail electric provider. The provider buys electricity from generation companies, and it buys delivery service from the transmission and distribution utility whose power lines serve the home, such as Oncor. The Public Utility Commission sets those utilities' transmission and distribution rates. Municipal utilities and electric cooperatives (with a few exceptions such as Lubbock), and utilities outside the ERCOT region, kept the older structure in which one utility provides generation, delivery and retail service (Texas Sunset Advisory Commission, PUC and ERCOT Staff Report (November 2022), Introduction: Texas Electricity Primer). A statewide residential average blends every utility's residential customers, and nothing on this page shows how much any project or power line added to a household's bill. EIA publishes the averages by state: Electric Power Monthly, Table 5.6.A.
