- ERCOT is tracking over 438 GW in large-load interconnection requests, approximately 89% from data centers [3] - Non-refundable interconnection fees set at $50,000/MW with study fees of $100,000–$300,000 depending on project size [2] - Data centers must pay transmission charges once capacity becomes available, even before facilities are energized [1] - Batch Zero process applies to loads of 75 MW or greater, with Batch 1 applications opening Summer 2027

Governor Greg Abbott announced on July 26 that the Public Utility Commission of Texas and the Electric Reliability Council of Texas have enacted a series of actions requiring data centers to fully fund the costs of electric infrastructure needed to serve their operations — including new power lines, substations, and grid upgrades [4]. The measures follow Abbott's June 10 directive ordering regulators to ensure residential ratepayers are not burdened by costs driven by the rapid scale of data center development in the state
.
[5]The regulatory overhaul comes as ERCOT tracks more than 438,000 MW of large-load interconnection requests, approximately 89% of which originate from data centers [3]. Under the new framework, large loads of 75 MW or greater must post financial security before ERCOT planning studies begin, pay non-refundable interconnection fees of $50,000 per MW, and cover study fees ranging from $100,000 to $300,000 depending on project size
. Data centers must also begin paying transmission charges once capacity becomes available, even before their facilities are operational
[2]. [1]The rules are already reshaping the Texas data center landscape. Diode Ventures, a Kansas-based developer, withdrew plans for a large-scale computing facility near Cedar Creek Lake in Henderson County, East Texas, citing the new regulatory environment and community concerns [6].
The Rules #
The PUCT's new interconnection framework centers on the Batch Zero process, approved on June 18, which establishes a standardized procedure for evaluating large-load interconnection requests collectively rather than individually [3]. The process determines available transmission capacity by location through 2032, allocates capacity among qualified projects, and identifies necessary grid upgrades
.
[1]Key financial requirements include non-refundable interconnection fees of $50,000 per MW and study fees of $100,000 to $300,000 depending on project size [2]. Applicants must post financial security for any system upgrades necessary to reliably serve their load, as determined by the interconnecting utility or transmission service provider
. Forfeited security deposits will be used to offset transmission rates for other customers
[2]. [7]A separate rule adopted in March requires that generation capacity available before September 1, 2025, must remain accessible to existing Texas customers, even if primarily serving new large loads. ERCOT must vet any such arrangements [7]. Additionally, utilities are now required to standardize how they report proposed large loads into ERCOT forecasting, a measure designed to prevent unnecessary transmission overbuilding
.
[7]## Governor Abbott's Directive Abbott's June 10 directive established two hard deadlines for regulators: a joint PUC-ERCOT memorandum to the Governor's Office by July 17, and PUC action to reduce residential transmission costs by July 31 [5]. The directive instructed regulators to require data centers to 'fully fund the costs of electric infrastructure needed to serve their operations' and to pursue legislative measures including mandatory water-efficient cooling systems, electricity and water consumption reporting, and the phase-out of outdated tax incentives for data centers
.
[5]On July 26, Abbott announced the cumulative actions taken in response, including new mandates requiring data centers to reduce power quickly when directed by ERCOT and strengthened evaluation processes for data center development proposals [4].
Batch Zero Timeline #
The Batch Zero process operates on an aggressive timeline. The deadline for projects to submit required technical studies and documentation was July 10, 2026 [3]. ERCOT will notify applicants of their project classification by August 7
. By spring 2027, ERCOT will provide each Batch Zero participant with the amount of electricity that can reliably be allocated to their project
[3]. [3]Applications for Batch 1 will open in Summer 2027, with a final transmission plan expected by Fall 2027. Most projects are expected to reach operational status by 2030 [3]. The process involved over 200 hours of stakeholder discussion, workshops with approximately 500 participants each, 200 survey responses, and more than 290 written comments
.
[3]## Market Impact The regulatory shift is already having tangible effects on the Texas data center pipeline. Diode Ventures withdrew its proposed computing and cooling facility near Cedar Creek Lake, which would have utilized lake water for cooling. The company stated that 'the site under evaluation, in particular its close proximity to the rural residential community of Cedar Creek Lake, does not meet the higher standard we believe should guide data center development' [6].
The withdrawal followed significant community opposition, including a volunteer coalition called Save Cedar Creek Lake that gathered thousands of petition signatures [6]. The project's cancellation suggests Abbott's directives are providing regulatory cover for communities resisting data center siting.
PUCT Chairman Thomas Gleeson framed the regulatory stance as pro-development but conditional. 'It must do so in a manner that prioritizes affordability, reliability and the interests of the residents who depend on the grid,' Gleeson said [1].
Legislative Outlook #
The PUCT and ERCOT are seeking additional legislative authority beyond their current rulemaking powers. The agencies have requested explicit reliability-setting power over large computational loads, direct curtailment authority for ERCOT during grid stress, mandatory data center registration with state agencies, and expansion of the Lone Star Infrastructure Protection Act to cover large-load facility owners [7].
These requests align with Texas Senate Bill 6, passed earlier in 2026, which reformed interconnection and co-location rules for data centers and other large loads [8]. The combination of executive directives, agency rulemaking, and legislative action represents the most comprehensive state-level regulatory framework for data center grid access in the United States.
