The extensive audit of Texas data center grid connections is on track, as regulators take action throughout the state. Currently, work is progressing on evaluating all large-load projects in ERCOT’s interconnection process. The Public Utility Commission of Texas (PUCT) and ERCOT are collaborating to discuss the next steps.

The current audit was designed to help the state safeguard residential ratepayers from the high price of infrastructure expansion. The regulatory review is for over 474GW of connection requests, where 90 percent is due to data center loads. Further, it is being planned as a compliance-based exercise, which is aimed at making data centers foot the bill for their own water usage. It also focuses on ensuring they supply their own water and reduce the effects on neighboring properties.

In June, Governor Greg Abbott first announced plans to immediately protect ratepayers when expanding data centers, with campuses such as Apollo data center by Cipher rising. Recently, the governor ordered that any facility that did not meet state requirements would not be connected to the grid. The instruction also seeks to lay the benchmarks for independent system operators with large industrial loads.

Outlook on the Texas Data Center Grid Audit

The Texas data center grid audit has been deemed an important safeguard for the safety and quality of life for community members. The governor’s office says this is based on insights from the recent mandate. After the audit, the state will severely limit transmission capacity allocation to what the grid can handle safely.

Once the audit is done, the state will be able to allocate transmission capacity strictly based on what the grid can handle safely. ERCOT also plans to review eligible facilities in accordance with its recently approved batch connection program. Our first priority is to keep Texans safe and healthy,” Gov. Abbott said.

The development of the rules addresses another snag that occurred during an unprecedented surge of industry demand, the governor making it official: “Texans must always come first” before any other projects to advance data centers are considered.

Project Overview

• Project Value: Managing 474GW of power requests
• Location: Texas
• Developer: PUCT & ERCOT
• Status: Comprehensive audit under execution

Scope

• Statewide audit of all data centers seeking grid connection
• Review of independent power and water supply utilization
• Assessment of facility ownership and controlling interests
• Implementation of a new batch connection framework

Project Highlights

• Protection of residential ratepayers prioritized
• Strict denial of grid access for non-compliant facilities
• First instance of an independent system operator adopting large-load batch rules
• Evaluation of community and property footprint impacts

Key Developments

• Gov. Greg Abbott issued official audit directive
• ERCOT approved new grid connection rules in June
• Over 474GW of connection requests currently pending
• PUCT and ERCOT instructed to gather detailed compliance data

Key Challenges

• Connection requests exceed five times the state’s record peak demand
• Massive 90 percent data center load straining grid planning
• Ensuring large facilities do not burden local water supplies
• Identifying and also funding necessary transmission upgrades

Outlook

• Data center projects await ERCOT batch study results
• Also regulatory scrutiny over hyperscale expansion likely to continue
• Grid access also depends entirely on strict audit compliance
• Also broader stakeholder framework development remains active
