The Invisible Tax: The Company Town, Metered Monthly

Loudoun County, Virginia calls itself "Data Center Alley," and it is not a boast so much as a census: the largest concentration of data centers on earth sits in its soil, drawing power on a scale that has bent the whole state's electricity system around it. Which makes Loudoun the cleanest place in America to answer a plain question — when the machines need a bigger grid, who pays for it? For years the honest answer was: everyone, quietly. This winter, Virginia's regulators changed that answer, and how they changed it tells you exactly what had been happening.

Here are the facts of record. In its 2025 review of Dominion Energy, the Virginia State Corporation Commission approved rate increases that will raise the average residential bill by $11.24 in 2026 and another $2.36 in 2027, pushing the typical household toward about $165 a month — while noting the increase was far below what Dominion asked for. In the same proceeding, ratepayers and advocates argued the request was "designed primarily to subsidize data centers," and the Commission acted on the concern: it approved a new GS-5 rate class for customers drawing 25 megawatts or more — in Loudoun, that means data centers — taking effect January 1, 2027, and it required those large users to cover a minimum of 85% of their contracted distribution and transmission demand and 60% of generation demand. In plain terms: the machines will now have to pay for a large share of the infrastructure built specifically to serve them, rather than folding it into everyone's bill.

Read those two facts together and the "economic development" story cracks. A data center is sold to a county as an economic engine, and it does pay real local taxes. But it is also, by design, one of the least labor-intensive industrial facilities ever built — an enormous, permanent electricity load matched to a handful of on-site staff. So the promise ("jobs, growth, tax base") and the demand ("a new substation, a transmission overhaul, gigawatts of capacity") are wildly out of proportion, and for years the difference was amortized across the residential rate base — the invisible tax of the headline. The utility gets a guaranteed return on every mile of line it builds; the data center gets its capacity; the household gets a bigger bill and a press release about jobs it will never hold.

Did AI do this, or did we?

No algorithm wrote a rate case. This was a regulatory arrangement built by people: a utility with a profit incentive to build and socialize, a data-center industry with every reason to keep its induced costs in the general pool, and a "company town" politics in which the two largest players negotiate and the town council is mostly invited to watch. What is genuinely new — and worth stating plainly, because this desk does not only report the capture — is that the arrangement was caught and partly corrected on the record. The SCC's cost-allocation reform exists because advocates did the unglamorous work of reading the filings and proving where the money was going. The invisible tax became visible, and once it was visible it became harder to justify. That is the system working, late and under pressure, but working.

What we are not claiming: that Virginia has solved it (the 2027 rules are a floor, not a fix, and the residential bill still rose), or that data centers pay nothing (they are large ratepayers and taxpayers). The documented concern is the default setting — that absent someone forcing the issue in a rate case, the physical infrastructure of the AI build-out gets built on the public's monthly bill, under an "economic development" banner sized for a factory that no longer employs a town. Loudoun is the case file. The national mechanism — how this same cost-shift runs in states without Virginia's scrutiny — is in our companion piece, The Infrastructure Subsidy.

The company town is an old American story. The only new part is that the company is a building full of GPUs, the wage is a rate hike, and the ledger is your utility bill. Our Energy lane reads that ledger line by line.
