A Political Compromise Becomes National Policy
On June 30, 2026, Governor Abigail Spanberger signed Virginia's biennial budget into law, encoding a precedent that data center operators had spent years lobbying against: a consumption tax on electricity. The previous political equilibrium—substantial sales and use tax exemptions in exchange for data center investment—had held for two decades, turning Northern Virginia's "Data Center Alley" into the world's largest concentration of computing infrastructure, hosting roughly 13 percent of global data center operational capacity, according to Virginia's own Joint Legislative Audit and Review Commission (JLARC). What broke that equilibrium was not a sudden change of heart about the industry's value. It was arithmetic. The alternative on the table was worse.
What HB 30 Actually Creates
Virginia's HB 30, enacted through the 2026 Special Session I budget process, imposes a tax of $0.011 per kilowatt-hour of electricity consumed at each Virginia data center beginning July 1, 2026. The tax applies to electricity supplied by utilities, competitive retail providers, and crucially, power generated on-site—covering behind-the-meter generation that had previously escaped any levy. Facilities must have at least one megawatt of electrical capacity to be covered, excluding smaller telecommunications and ISP infrastructure.
The State Corporation Commission administers collection, with the first payment due September 2026 covering July through September activity. An annual revenue cap limits deposits to Virginia's general fund at $600 million per year; any excess is held in a special nonreverting fund and returned to operators pro-rata based on their tax payments. The tax expires June 30, 2028, absent legislative renewal. Governor Spanberger described the measure as "a compromise proposal—one my administration helped craft—that builds a strong foundation for further discussions about the future of this industry in Virginia."
Evercore ISI estimated a 100-megawatt facility would face roughly $9.6 million annually in additional costs—approximately a 10-to-11 percent effective increase in electricity rates. For a 500-megawatt campus, that reaches $48 million. These are real numbers, but Evercore characterized the levy as "non-trivial but not existential for hyperscalers."
Why Regulators Had a Point
Before dismissing this tax as an overreach, it is worth engaging honestly with the pressures that produced it. Northern Virginia's data center boom has not been cost-free for other ratepayers. PJM Interconnection's 2025–2026 capacity auction cleared at a price 833 percent higher than the year prior, driven substantially by surging data center demand. Virginia's own grid projections show state electricity demand rising 183 percent by 2040 under unconstrained data center growth—compared to 15 percent without it. That incremental grid investment does not pay for itself.
The JLARC's 2024 report on Virginia data centers documented that while the industry generates $9.1 billion annually in state GDP and 74,000 jobs, the fiscal math has shifted. The state's sales and use tax exemption saved the data center industry $928 million in FY2023 alone. Meanwhile, 42 community activist groups and 12,000 petition signatures opposing data center expansion in Virginia signal that the social license to operate under the old deal is eroding. The political compromise that produced this tax was not manufactured by technocrats hostile to industry. It was a response to genuine constituency pressure the industry had failed to get ahead of.
Why the Design Falls Short
Acknowledging the legitimacy of the underlying concern does not require endorsing the specific remedy. The fundamental problem with Virginia's electricity tax is that it routes revenue into the general fund rather than dedicated grid infrastructure investment. The $600 million cap was calibrated to satisfy budget negotiators, not to address grid resilience or distribute infrastructure costs more equitably. Former FERC Chairman Mark Christie's assessment is apt: the measure "will do nothing to protect residential consumers from cost-shifting" on necessary infrastructure investments.
A consumption tax deposited in the general fund is disconnected from the actual externalities it is meant to address. It does not create incentives for efficiency investment, water conservation, or demand flexibility. Notably, the same budget separately mandated that new data centers in Virginia's Eastern Groundwater Management Area—facilities applying after January 1, 2027—use air cooling, recycled water systems, or closed-loop solutions. That cooling mandate, though limited in geographic scope, is a more direct policy instrument: it targets a specific externality with a specific behavioral requirement. The electricity tax, by contrast, is a revenue mechanism dressed in the language of energy policy.
The Precedent Every State Will Face
Virginia is a bellwether, and the industry should not mistake its strategic position. When the largest data center market in the world imposes a consumption tax and retains its equipment exemptions, it establishes a template. Ohio, Maine, and Illinois have separately moved to suspend or repeal data center tax exemptions. Analysts at Evercore ISI noted that "the combination of rising fiscal pressures and anxiety about the socioeconomic fallout from AI adoption is likely to make data centers a ripe target for new revenue proposals" across jurisdictions.
The question is not whether other states will attempt similar measures, but whether they will adopt Virginia's relatively structured approach—capped, time-limited, with refund mechanisms—or something less carefully designed. The industry's best outcome is not to fight the template, but to shape it. A consumption tax with a hard cap, pro-rata refunds for over-collection, and a two-year sunset is materially better than an open-ended exemption repeal. What it lacks is a mechanism tying revenue to grid infrastructure—an investment that would benefit data center operators, residential ratepayers, and grid reliability simultaneously.
If the industry engages constructively on that design question in Virginia's 2028 renewal debate, and in the copycat legislation that will follow elsewhere, it can convert a reactive political compromise into something approaching actual energy policy. The $600 million per year will flow to Virginia's general fund regardless. The choice now is whether the next version of this tax is smarter, or merely more expensive.
