Data Centres: Boom and Backlash

Virginia forces water draw into daylight

A new Virginia law will make water utilities report data-centre use separately from 2027, landing as Google fights to keep one Botetourt County site's draw sealed after a court forced its release.

IndustryDeveloping
Key takeaway

Virginia will make utilities publish data-centre water draw, closing the gap voluntary disclosure leaves open.

A new Virginia law, reported on 25 June and prospective to 2027, will require waterworks to break out data-centre sales from household and industrial customers, ending the aggregation that has hidden site-level draw. 1 A utility that today reports one lumped figure will have to name what its data centres take.

The mandate lands on an awkward record. Google markets itself as the only hyperscaler that publishes per-site water figures, yet its Botetourt County subsidiary spent months fighting a freedom-of-information request for that exact site data, needing a November 2025 court order to release it. 2 A Google director had argued in an affidavit that the numbers could let rivals infer the campus's size and design. The figures a judge finally prised loose, a draw rising from 2 to 8 million gallons a day, 7 to 30 times the utility's largest existing customer, never appeared in Google's own sustainability report.

The company had earlier answered the water question on its own terms, pledging $17m in replenishment as its Dalles, Oregon site faced a steep rate rise . That is the gap the law closes. Voluntary disclosure lets an operator choose the framing, the baseline and the offset; a statutory per-class report does not. Google's Botetourt fight shows what a company will do to keep a single site's number sealed even while branding itself the transparent one, which is why the 2027 mandate matters more than any pledge.

Deep Analysis

In plain English

Starting in 2027, Virginia's water companies will have to say exactly how much water data centres are using, separately from homes and factories. Right now that number gets lumped in with everyone else's, so nobody outside the company can see one site's actual draw. The law arrives just as Google has been fighting in court to keep exactly that kind of number secret for one of its Virginia sites, even though the company publishes its own water figures elsewhere, on its own terms, whenever it chooses.

Deep Analysis
Root Causes

The disclosure gap exists because water utilities have historically billed data centres inside an aggregated industrial-customer class, so no single invoice ever isolated one campus's draw; Virginia's law is a billing-classification fix, not a new water right or a discharge limit, which is why it took a legislative change rather than a permit condition to close it.

Google's Botetourt objection rested on a specific competitive-harm theory, that a precise gallons-per-day figure lets rivals infer a campus's size and cooling architecture, a concern its own voluntary aggregate reporting was structured specifically to avoid triggering.

What could happen next?
  • Consequence

    Utility-level reporting from 2027 will let Virginia regulators and journalists compare data-centre water draw across sites for the first time, ending the aggregation that let voluntary corporate figures go unchecked.

  • Precedent

    Other water-stressed states can adopt the same utility-reporting mechanism without waiting for a hyperscaler to volunteer site-level data.

Causes and effects
This Event
Virginia forces water draw into daylight
Statutory per-class reporting removes the aggregation that lets operators publish flattering company-wide figures while site-level draw stays hidden.
Different Perspectives
Global hyperscale operators
Global hyperscale operators
Operators are still filing gigawatt-scale campuses and Meta is proceeding with its $10bn Lebanon, Indiana site despite the county-level bans nearby, betting Q2 capex outruns the patchwork of restrictions. Industry framing casts New York's freeze, Oregon's surcharge and Indiana's bans as taxes and levies that push build-out toward faster-permitting jurisdictions such as India and the Gulf.
EirGrid
EirGrid
EirGrid set a 900 MW instantaneous demand-loss ceiling because a single voltage dip can trip many data centres onto backup power at once, risking imbalance above 1,150 MW. It wrote the limit into a standing procedure rather than waiting for an emergency to force one.
US host communities and ratepayers
US host communities and ratepayers
Prince William residents backed the 8-0 denial of Dulles South over the Occoquan watershed, drinking water for eight million people, while Oregon's approved tariff cuts residential bills 1.3% by charging large loads 29% more. Their position: consent and cost-attribution belong in law, not left to a developer's or a utility's discretion.

Hassan Allam Digital Infrastructure, an Egyptian conglomerate rather than a foreign hyperscaler, reportedly secured a domestic hyperscale licence with a $400m first phase, per single-source reporting still to be verified. It reads as home-grown sovereign compute ambition, building national capacity rather than importing a US or Gulf operator's campus.

Damac Digital keeps building toward roughly 6,000 megawatts of hyperscale capacity across 13 countries while Virginia taxes power and New York weighs a freeze. Every dollar or month of delay a US state adds is capacity a Gulf developer can site somewhere with faster permitting and no equivalent levy.

Santa Fe County commissioners voted unanimously on 2 July to freeze any data centre over one megawatt, citing the acequia irrigation commons that has shared scarce water since Spanish colonial rule. They expect the low threshold to draw the same Fifth Amendment challenge RCM Hill brought against Hill County, Texas.
