The EPA’s Temporary Loophole Won’t Power the AI Boom

T he Environmental Protection Agency’s recently issued temporary guidance declares that “islanded” power plants — in other words, those serving only data centers and disconnected from the public grid — fall outside the Clean Air Act’s provisions. In so doing, the agency concluded such power plants shouldn’t be subject to the same regulations as electrical generation sources that are connected to the public grid.

However, this temporary guidance is just that: temporary. It’s a step in the right direction, but it’s no substitute for lasting legal certainty.

The EPA’s new guidance is meant to be a pragmatic boost for America’s AI infrastructure boom, with the goal of accelerating data-center construction, easing pressure on regional grids, and ensuring that ordinary citizens are not subsidizing the electricity demands of tech giants. “Ensuring that the United States maintains our artificial intelligence dominance is essential to national security and economic prosperity. At the same time, it is equally important that we safeguard our communities from utility price hikes,” said EPA Assistant Administrator Aaron Szabo. “This guidance will provide an avenue to do both.”

Yet this approach is inherently inadequate, as an agency’s guidance and interpretive letters are not durable law. They are simply the current administration’s view, and can potentially be withdrawn, narrowed, or reversed by the next EPA administrator. Any future president could undo this reform with the stroke of a pen. In practice, given the fragile legal assurance they provide, the EPA’s temporary guidance prevents businesses building multi-billion-dollar facilities with multiyear lead times from being able to responsibly plan for the future. Data centers are major infrastructure assets and can operate for 30 years; as such, while temporary guidance extending until the next presidential election can be somewhat useful in the moment, it is fundamentally unable to stimulate necessary investment.

The risks associated with a lack of permanence are evident. Progressive Democrats such as Senator Bernie Sanders (I., Vt.) and Representative Alexandria Ocasio-Cortez (D., N.Y.) have already gone so far as to propose a federal ban on data-center construction, while even comparatively moderate Democrats such as New York Governor Kathy Hochul have enacted statewide construction moratoriums. Given the barely-concealed presidential ambitions of Ocasio-Cortez and other leading Democratic antagonists of data centers, apolitical investors have good reason to not have full faith in the temporary guidance’s long-term durability.

AI infrastructure is already about as important to the U.S. economy as defense spending, making up roughly 2 percent of America’s GDP. It’s the most rapidly growing driver of the U.S. economy. The AI revolution has the potential to be as economically transformative as the internet, or even electricity itself.

Despite what progressives claim, building the electrical infrastructure necessary to support the AI revolution will ultimately benefit American families and businesses. But achieving that requires creating a stable legal environment in which to build.

Training and running frontier AI models requires enormous, concentrated computing power housed in giant “hyperscale” data centers that can consume hundreds of megawatts each — as much energy as is required to power entire cities. Data centers already consume 4.4 percent of U.S. electrical power; this demand is projected to grow dramatically in coming years. “The U.S. will continue to account for over half of the world’s data center capacity, and total U.S. capacity will double over the next three years,” John Dinsdale, chief analyst and research director for Synergy Research Group, told the computer publication CRN.

Such assets demand enormous upfront capital, long-term power-purchase commitments, and other irreversible site decisions. Investors, lenders, and operators need to know that the regulatory baseline will still exist years down the line. However, if rules can flip with election cycles, projects face higher risk premiums, delayed financing, or outright cancellation. Some developers may proceed under the current interpretation, only to confront costly retrofits, permit challenges, or stranded assets if this guidance is later rescinded. Others will simply wait on the sidelines, slowing the very AI and computing capacity that the policy purports to unlock.

Permanent legal certainty requires more than just an EPA legal interpretation. Congress should instead amend the Clean Air Act to clarify treatment of behind-the-meter or exclusively private generation — targeted legislation that would balance the realities of surging digital demand. Alternatively, the EPA and other agencies could conduct formal notice-and-comment rulemaking. While slower, this would produce regulations that are harder to unwind overnight and more likely to survive judicial review. Another potential solution is Consumer Regulated Electricity (CRE) — privately financed, physically “off-grid” utilities serving new large customers, such as data centers, under voluntary contracts. These systems would not impose any costs, reliability risks, or stranded-asset burdens on the existing regulated power grid.

The U.S. needs both rapid expansion of computing infrastructure and predictable rules of the road. Temporary administrative accommodations may deliver short-term political wins and modest flexibility, but they aren’t good enough. Businesses will invest at the scale required only when the law itself, not the preferences of the current White House, provides confidence that the rules will remain standing when their facilities come online. Anything less is insufficient for the task.
