Data Centers in Virginia, Georgia and Tennessee

An independent, primary-source series on data center policy in Virginia, Georgia, and Tennessee, maintained like a legal treatise with an update service. Volumes are revised as county votes, regulatory filings, and state budgets change the record, and the latest version of each is the current text. Every volume has a permanent DOI that resolves to its newest version.

The series covers state fiscal policy, utilities and generation, transmission, water, gas supply, county land-use decisions, and the organizations on every side. Every work is built from filings, orders, dockets and minutes, and is free to read under a CC BY licence. 50 works. Suggested starting points are marked with a star. Looking for a particular county or city? See data centers by Virginia locality. Op-eds, trade pieces and coverage of the work are at the end of the page.

Statewide references

The fiscal and inventory foundation, the argument that runs across the county cases, and the census of who took part.

Utilities, generation and transmission

Who builds the power, who reviews it, and who pays for the wires.

Water

What the withdrawal rules reach, what they record, and where a utility-supplied data center disappears from the record.

Virginia county case studies

Fourteen localities, read from their own packets, minutes, ordinances and agreements.

Georgia and Tennessee

Statewide reports and the federal record for the two companion states.

Jobs and construction labor

What the employment record shows about who builds and staffs data centers, and building trades membership from federal union filings.

One essay above the research threads, page-referenced to the deposited works.

Datasets

Registers, replication materials and source manifests behind the reports.

Commentary and coverage

Op-eds and trade pieces drawn from this research, newest first, and outside reporting and research that cite it.

Commentary

  1. Researcher: Valley Link is now $5.1 billion and 2031. PJM's own rules give the counties a question to ask.

    PJM's Nov. 3 materials raise Valley Link from $3 billion to $5.1 billion and move all 14 of its projects past their June 1, 2029 date; the Joshua Falls to Yeat line now shows Jan. 17, 2031. PJM's operating agreement says that when a developer misses a milestone and the project is delayed, PJM "shall re-evaluate the need" for it. The counties along the route and their landowners can put five questions to PJM in writing before its board acts.

  2. PJM's Tx Owners Would Lock In What a Data Center Pays

    The transmission owners' plan would have whoever buys transmission service for a data center sign on for 10 to 20 years and promise a minimum payment, backed by a letter of credit. It never asks whether that payment covers the local lines and substations the data center requires; a footnote keeps those costs in the rate shared by everyone in the zone. PJM reviewed over $9 billion of such supplemental projects in 2024.

  3. Who goes dark first, data centers or us?

    Botetourt County's website promises that homes, schools, hospitals and emergency services come before Google's data center when power runs short. The county can make that promise and has no power to keep it: Appalachian Power would do the cutting, and no Virginia rule tells it whether homes go dark before data centers. The commission should write the county's answer into a rule the utility has to follow, and DEQ should write the generator trade into Google's air permit, with every emergency run reported in public.

  4. A noise limit on data centers is only as good as its measurement

    A Loudoun supervisor said the county's average readings beside the Vantage campus never passed 55 dB(A); a resident half a mile away measured 70 to 80 decibels. Neither disproves the other. Every noise ordinance decides which frequencies count, which samples count, how they are averaged and where the meter stands, usually without saying so. Of the 75 Virginia instruments adopted as law, 42 carry no numeric decibel limit at all.

  5. Virginia Decides Who Pays for Data Center Hookups but not the Upgrades

    The SCC's July 31 order makes a large new customer pay up front for its own hookup to the grid and puts off the expensive part: the supplemental upgrades its arrival makes necessary, which reach every Dominion customer through a transmission charge. Dominion planned $1.28 billion of those local projects for 2026. The order already lists the fix.

  6. Researcher: The data center jobs are real. So is everything else on the ledger.

    A reply to Dwayne Yancey's Sept. 29 column on data center jobs. The 50-jobs figure is the number Virginia's tax exemption requires, union membership in data center metros grew faster than employment, and the rest of the ledger, from Botetourt's Google agreement to transmission, water and the exemption's unmeasured effect, has never been added up.

  7. FERC Leaves Fuel Question to States; Virginia's Order Doesn't Answer it

    The SCC certificated a 944 MW DOM Zone peaker on PJM's capacity shortfall without stating its capacity factor or what it costs to get gas to it. FERC leaves that question to state regulators; three weeks after Virginia's hearing closed, Dominion's fuel subsidiary signed for 20 years of Mountain Valley capacity, and neither record mentions the other.

  8. The Realtors' new data center study says nine Virginia counties have none. Virginia permitted them.

    The National Association of Realtors' Sept. 9 study sorts the nation's counties by how many data centers each has. It files Stafford County under "No Data Centers" six months after Virginia issued Amazon an air permit there, along with eight more Virginia localities holding state permits for named sites. The count comes from OpenStreetMap, and the study's own two versions of it put one county in five in a different group.

  9. The thousand-dollar line

    Loudoun priced the fix at $1,000 in 2016 and passed on it, citing competitive disadvantage. A decade later, Prince William raised its residents' 18 recommended sound values by 6 decibels each — and that weakened standard is now the strictest thing Virginia has.

  10. Researcher: Buckingham will host more of this power line than any county in Virginia, and it has the least say about it

    Buckingham hosts more of the Valley Link line than any other Virginia county — more than Louisa, Orange, or Culpeper, all of which have data centers. Tested against 2,000 random corridors, the route runs through data-center counties more often than chance would allow. Nobody aimed it there, and nobody in Virginia can undo it.

  11. Local governments cut out the public

    Botetourt, Wythe, and Pulaski each disclosed on schedule. The problem is the schedule — information arrives after a project has accumulated enough commitments to make reversal expensive.

  12. Half of a 765-kV Line in PJM is a Postage Stamp; the Other Half Stops at the Zone Line

    PJM's Schedule 12 allocates half the cost of a data-center-driven transmission line by geography and half by ignoring it — nothing in the tariff conditions on where the burden actually falls.
