Two prices decide where a data center lands: the price of power and the price of permission. On August 20, TVA set the first one. Middle Tennessee's counties keep repricing the second — and the second is the one that moves land values.
What TVA actually did
At its August 20 board meeting, TVA approved its first dedicated rate class for data centers. Any data-center load above 5 megawatts now carries a Capacity Commitment Charge, designed to recover the cost of new generation from the users driving it rather than spreading it across households. TVA expects the all-in average billing impact for data-center customers to run about 10 percent, phased in over three consecutive fiscal years, effective October 1, 2026. The same meeting produced an approved 2026 Integrated Resource Plan that projects the Valley needs 11 to 32 gigawatts of additional generation by 2040 — much of it for data centers.
Here is the read that matters for landowners: a 10 percent utility premium does not kill a hyperscale project. Power at these facilities is a cost of goods, and the operators signing these deals model it to the decimal. What the new rate does is standardize the price of electricity across the Valley. When every county pays roughly the same for power, power stops being the differentiator. The scarce input is not a kilowatt. It is a parcel near capacity, in a county that says yes.
The permission map keeps shrinking
That second price — permission — has been repricing all summer, county by county:
Metro Nashville passed its first data-center regulations on July 21, paired with a construction pause that runs through December 2026. Wilson County's commission approved a six-month countywide moratorium on July 20, which carries it into late January 2027 (Main Street Media). Maury County's commission adopted a moratorium of up to 12 months for its unincorporated areas the same week — commissioners rejected a 24-month version after the county attorney advised that courts view one-year pauses as defensible and two-year bans as exposed (Frontporch Radio, July 23). Gallatin approved a 60-day application pause in late July while a full moratorium works through its planning commission (News4 Nashville).
Two entries most people missed. Dickson County — which I had on the permissive side of my map a month ago — adopted its own six-month moratorium on July 22 by an 11-0 vote (Dickson Post). And tiny Coopertown in Robertson County has a two-year data-center moratorium at second reading on August 25, moving to shut the door before a single application arrives.
Count it up. Of the counties in my coverage area that a site selector would shortlist, the ones still fully open for data-center development now come down mainly to Montgomery and Smith, plus pockets elsewhere that have not yet acted. The permissive map is not shrinking slowly. It has lost Davidson, Wilson, Maury, and Dickson in five weeks, with Robertson and Bedford drafting.
Demand does not disappear. It relocates.
This is the part no news outlet writes, because no outlet prices land for a living. TVA's own planning documents say data-center load across the Valley doubles by 2030. That demand does not evaporate because Wilson County paused for six months. It moves — to the counties that stayed open, and to the parcels inside them that sit near transmission, substations, water, and fiber.
If you own acreage in Montgomery or Smith County near power infrastructure, your dirt repriced this summer and the market has not told you yet. The buyers who call will know exactly what the TVA rate change and four county moratoriums did to your parcel's scarcity value. You should know it first.
If you own land in a restricted county, you have a window problem, not a dead asset. Nashville's pause expires in December 2026. Wilson's runs to late January 2027. Maury's runs up to twelve months. Moratoriums are pauses, and buyers time entitlement risk the way they time interest rates — they option land during the pause and close after it lifts. The offers that arrive mid-moratorium price in the uncertainty. The question is whether you sell the uncertainty or the resolution.
The bottom line
Power is now priced uniformly. Permission is priced county by county, and it is repricing monthly. That spread — between what a megawatt costs and what a yes costs — is where Middle Tennessee land value gets made and lost right now. I track planning agendas across all 16 counties every week so my clients see these moves before the market does. If your land sits near power in a county that still says yes, know your number before someone else names it.
