Tech companies are lining up to voice support for Gov. Greg Abbott’s audit of data centers seeking to connect to the power grid, although little is known about what the audit will entail or what it means for the data center construction boom.

Since the Aug. 3 announcement, at least 43 companies — including juggernauts like Meta, OpenAI, Microsoft and Amazon Web Services — have issued public statements expressing support for Abbott’s audit, despite the governor ordering regulators to not approve any new grid connections until the audit is completed. The governor has similarly touted their endorsement of his plan.

“We share your commitment to ensuring data centers are true partners in every Texas community where we operate — protecting residential ratepayers, strengthening grid reliability and promoting responsible water stewardship,” read a letter to the governor sent Tuesday by the Data Center Coalition, a trade association representing many of the largest tech companies in the world.

Abbott directed the Electric Reliability Council of Texas, which operates the state’s power grid, to conduct the audit, but it’s unknown how long the audit will take, how long the moratorium on grid connections will last, how many data centers will be audited and how the information gathered in the audit will be used by regulators and legislators.

Without these questions answered, it’s unclear how much of this audit will address the public’s concerns about data centers, particularly their impact on energy access, water use and the environment.

Citing polling data that shows growing discontent among rural Texans toward the buildout of data centers and competitive General Election contests for governor and U.S. Senate, Texas Politics Project Director Jim Henson said the moves by Abbott and the companies raise questions about how impactful the audit and freeze of approvals will actually be.

“It’s all very performative, it’s performative on everybody’s part,” Henson said.

Abbott’s office has largely directed questions about the audit to his public statements on the topic since Aug. 3. The PUCT and ERCOT have also remained largely silent on the matter, and the PUCT scheduled an emergency meeting for Friday morning to discuss the issue.

ERCOT did say in a Monday filing it expects the audit will last “several months” and is expected to begin shortly after Aug. 20.
