Data center operators in Texas already operate under one of the most consequential state-level regulatory frameworks in the country. SB6 — signed in June 2025 and effective immediately in ERCOT — shifted interconnection costs and reliability obligations onto large-load customers, including virtually every data center above 75 megawatts. Now, on August 19, 2026, a new federal bill has been introduced that would add a direct electricity tax on data centers at the national level.

Taken together, the two measures signal that the era of data centers as lightly regulated, massive electricity consumers is ending — and Texas, despite its pro-business reputation, is at the forefront of that change.

"Texas, and ERCOT in particular, is experiencing more demand and requests for power capacity than any other region in the country, and other states are already moving in a similar direction, many with even more restrictions and stiffer economic consequences." — Curt Holcomb, JLL, on SB6

Layer One: Texas SB6 — What It Actually Does

SB6 is not symbolic. It changes the economics of data center development in Texas in concrete ways. The law applies to large-load customers interconnecting within ERCOT — which covers most sizable data centers — specifically targeting loads of 75 MW or more. Its key provisions, effective for non-critical large loads interconnecting on or after December 31, 2025, include:

SB6 Key Provisions (Effective Dec 31, 2025)

Large-load customers must shoulder a greater share of grid-connection costs, including a flat initial transmission screening study fee of at least $100,000
Interconnection applications must include proof of site control and evidence of financial commitment to build required infrastructure
Operators must disclose on-site backup generation capable of serving at least 50% of on-site demand to utility partners and ERCOT
During emergency conditions, ERCOT may direct facilities to curtail load or operate existing on-site backup (with reasonable notice)
Non-critical large loads must incorporate remote-disconnect capabilities for emergency load shedding
PUCT and ERCOT directed to establish uniform standards for demand-response and reliability services

SB6 does not impose a universal on-site backup generation mandate — that's an important nuance. But the disclosure requirement and the emergency curtailment authority represent a meaningful shift from the prior status quo, where data centers had what one analyst described as "a fairly cushy ride" with broad latitude in how much contracted power they actually consumed.

Actual consumption of contracted power typically ranges from 50 to 60 percent for traditional data centers, though AI-focused facilities can be much higher. SB6 is, in part, a corrective to that pattern — aligning utility revenues more closely with the capacity they must maintain.

The PUCT is still writing the rule details into 16 TAC § 25.194, with adoption anticipated in September 2026. That rulemaking process will determine the final contours of the financial security requirements — currently proposed at $50,000 per MW — and the full scope of the disclosure obligations.

Despite the burdens, industry reaction has been relatively measured. Alex Cordovil, research director for physical infrastructure at the Dell'Oro Group, expects limited pushback: "We expect data centers to take the lead in many cases, especially when offers like this can place them in a more favorable position to secure some of the power they need. Data centers seem to be very open to being better grid players, offering support to the grid when it needs."

Layer Two: The Federal Electricity Tax Bill — August 19, 2026

On August 19, 2026, Data Center Knowledge reported that a new House bill had been introduced that would impose a federal electricity tax on data centers. The bill — which creates a new federal revenue stream tied directly to data center energy consumption — represents the first serious federal-level tax proposal aimed specifically at the data center sector.

The timing is notable. The bill lands just 16 days after Governor Abbott's August 3 directive halting new grid connections, and in the same week that ERCOT filed its "good cause exception" request ahead of the PUCT's August 20 meeting. The convergence of state and federal regulatory activity — at the exact moment Texas's data center market is going through its biggest transition — is not coincidental. It reflects a national pattern: as AI-driven electricity demand explodes, governments at every level are moving to capture revenue and impose accountability.

Why the Federal Angle Matters

A federal electricity tax would apply regardless of state-level regulatory environment. Texas — with its pro-business posture and independent grid — has positioned itself as a haven from the heavier regulation that data centers face in other states. A federal tax would partially erode that advantage by adding costs that every state's data centers would face equally.

How the tax would be structured — per-kilowatt-hour, per-megawatt-hour, based on total load or peak demand — and what rate would apply are still uncertain at this stage. But the principle is clear: data centers are becoming a targeted revenue source for governments facing massive infrastructure costs driven by AI demand.

Texas Is Not Alone — The National Picture

The regulatory wave extends well beyond Texas. New York Governor Kathy Hochul signed Executive Order 62 on July 14, 2026 — the nation's first statewide moratorium on new hyperscale data centers of 50 MW or more, directing the Department of Environmental Conservation to hold pending permits in abeyance while the Department of Public Service prepares a Generic Environmental Impact Statement. President Trump publicly criticized Hochul for the move.

Illinois Governor JB Pritzker directed the state's Department of Commerce and Economic Opportunity on June 5 to pause processing of Data Center Investment Program agreements starting July 1, after the Illinois General Assembly failed to advance legislation on data center energy and water disclosure and cost allocation.

Florida Governor Ron DeSantis signed Senate Bill 484 in May 2026, effective July 1, which defines large-scale data centers as facilities with anticipated monthly peak load of 50 MW or more, prohibits utilities from shifting service costs to residential and small-business ratepayers, requires public disclosure of development deals, bars ownership by "foreign countries of concern," and preserves local zoning authority to deny projects outright.

BloombergNEF described the Abbott directive as extending "a pattern of gubernatorial data center restrictions in 2026" — a pattern that now includes states representing a significant share of the national data center market. The Texas directive is distinct in its scale (the 474 GW queue is unmatched anywhere in the country), but the direction of travel is national.

What Texas Operators Need to Watch

State

SB6 Rulemaking

PUCT is writing final rules into 16 TAC § 25.194. Adoption expected September 2026. Key items: the $50,000/MW financial security requirement, full disclosure obligations, and backup generation reporting specifics. Operators should track this closely — the final rules will determine actual compliance costs.

Federal

Electricity Tax Bill

House bill introduced August 19, 2026 proposing a direct federal electricity tax on data centers. Structure, rate, and scope still undefined. If enacted, would apply to all U.S. data centers equally — eroding Texas's cost advantage. Operators should model the potential impact regardless of legislative odds.

State

Abbott Audit / Batch Zero

ERCOT's Batch Zero study is paused pending the PUCT August 20 open meeting and the outcome of ERCOT's good cause exception request. How the audit is scoped — what information is required, how long review takes, what "fails" look like — will determine whether projects can move forward.

State

2027 Legislative Session

The 90th Texas Legislature convenes in January 2027. Troutman Pepper Locke identifies this as the "next opportunity for statutory changes to data center regulation." PUCT has indicated it will seek expanded statutory authority. The Abbott audit's duration will influence what legislative changes are proposed — and whether they go beyond SB6.

The Market Signal

JLL's Curt Holcomb captured the broader shift succinctly: "Texas isn't the only state moving to tighten control over power supply... In lieu of legislation, utilities in some states are instituting restrictive rules or requiring substantial upfront payments from customers seeking additional power capacity."

Alan Howard, senior analyst for data center infrastructure at Omdia, offered a more sanguine take: "Personally, I don't think these kinds of regulations are bad as they drive builders to be more thoughtful about their approach, but they can certainly be a pain in the neck for the industry."

The underlying dynamic is clear: data centers have grown faster than the regulatory frameworks that govern them. SB6, the Abbott audit, the federal tax proposal, and parallel moves in New York, Illinois, and Florida are all symptoms of the same phenomenon — governments catching up to an industry that has fundamentally reshaped electricity demand in ways that were not anticipated when existing regulations were written.

For Texas — which has bet its data center future on being the most business-friendly option in a tightening national landscape — the question is whether these new layers of regulation are a manageable cost of doing business, or the beginning of a structural shift that changes the math on Texas as a data center destination. The next 12 months — through the Abbott audit, the September PUCT rulemaking, the federal tax bill's legislative trajectory, and the January 2027 legislative session — will provide the answer.
