Why Nashville is a market at all
Nashville is a headquarters and healthcare market. HCA Healthcare is here, and with it a dense cluster of hospital operators, revenue cycle companies and clinical software businesses that between them make health information the defining workload of this metro. Vanderbilt anchors research and academic computing, Bridgestone Americas and Asurion anchor corporate IT, and Oracle's campus commitment attached a large technology employer to a city that had not previously had one at that scale.
That mix produces enterprise colocation demand with a compliance shape to it: regulated data, retention obligations, audit requirements, and a preference for a building somebody can drive to. It does not produce a wholesale market. The multi-tenant layer here is small, it is aimed at cabinets, cages and small private suites, and a requirement measured in megawatts will exhaust it quickly.
The geography helps in two specific ways. Nashville is roughly equidistant from Atlanta, Chicago and Dallas, which makes it a workable recovery position for a primary in any of them, and Middle Tennessee is a low natural hazard region by the standards of the southeast: far enough inland to be out of the hurricane conversation, and without the seismic exposure of the west.
The rule that changed in July 2026
On 21 July 2026 the Metro Council unanimously passed two things at once: Nashville's first comprehensive data center zoning framework, and a temporary moratorium halting the acceptance, processing, approval and issuance of zoning, building and grading permits for data centers in Davidson County while the framework beds in.
The framework matters more than the moratorium, because the moratorium expires and the framework does not. It bans data centers larger than 500,000 square feet outright, confines the rest to heavy industrial land, requires a special exception process with a public hearing for the ones that remain, and imposes buffers around homes, schools, hospitals and the zoo. A proposed campus beside the Nashville Zoo is what prompted the whole exercise.
Read that as a ceiling on what this market can ever become inside the county line. A 500,000 square foot cap takes the campus-scale product off the table in Davidson County entirely, which pushes anything larger into the surrounding counties, where the utility is usually a different company. For a buyer that is not necessarily bad news: it means the multi-tenant buildings inside the city are unlikely to find themselves competing with a hyperscale campus for the same substation. It does mean that any expansion plan measured in megawatts belongs in a conversation about the ring, not the core.
What it means to be in TVA territory
The Tennessee Valley Authority is a corporate agency of the United States government. It generates power and sells it wholesale to about one hundred and fifty local power companies, which are the only entities that sell electricity at retail in its service area. In Davidson County that company is Nashville Electric Service, a municipal utility. In the fast growing counties around the city it is more often an electric cooperative. Tennessee has no retail electric choice, and the valley is not part of a regional transmission organisation, so there is no wholesale market price, no capacity auction and no competitive supplier at any point in the chain.
Two layers therefore sit between a data center and its energy cost, and they behave differently. TVA sets wholesale rates through its own board rather than through a state commission, which means the venue where large load pricing is decided is federal and is not the Tennessee Public Utility Commission that a buyer might reasonably expect to look at. The local power company then applies its own retail schedule on top, and those schedules differ from one utility to the next. Two buildings twenty miles apart can sit under different retail tariffs from different sellers, both buying from the same federal wholesaler.
The practical consequence for a tenant is that the answer to "what does power cost here" is genuinely building specific, and an operator who answers it at the metro level is either simplifying or does not know. It also means a large new service is negotiated with a local utility whose scale is municipal or cooperative, against a wholesale contract it does not control. Ask early, because the answer takes longer to obtain here than in a market with one investor-owned utility and one commission.
Ask which local power company serves the building, not which state it is in, and ask for the specific retail rate schedule the facility is billed on. Then ask how the operator's own recovery works: whether power is billed to you at metered consumption, at a committed draw, or blended into the rate. In a territory with no competitive supply, those two answers together are your entire power cost story, and neither of them is visible from a metro average.
Three do not. There is no permit collector pointed at Davidson County or the counties around it, so the public filing record is not shown here. Our facility inventory does not extend to this market, so there is no verified building count. And the interconnection layer counts a building only when its city sits on an explicit list, so Nashville and its suburbs are counted nowhere rather than counted wrongly. The fourth is here. The announced capacity below is collected by hand, and every figure in it was read on the page it links to before the row was written, which is also why some widely quoted numbers for this market are in the note under the table rather than in it. Announced is not built, and built is not available. See how we verify capacity for what each collection proves.
What has been announced in Nashville
Announcements are not filings. Nobody has to build what they announce, the figure is the one the developer chose to publish, and the date moves. They are here because megawatts are what a requirement is measured in, and because the size of what is coming changes who will take your call. Every figure below was read on the page it links to.
| Capacity | Operator | Project | What was announced |
|---|---|---|---|
| 50 MW | DC BLOX | Nashville campus, Grassmere Park | A 24 acre site at 648 Grassmere Park beside the Nashville Zoo, filed as two buildings of 40 MW and 10 MW with a substation. The company has since said it is working through the size and scope of the project, and its own site now shows only the smaller 10 MW building, so treat the 50 as the filed plan rather than the current one. Filed development plan, since narrowed |
| 12 MW | RadiusDC | Nashville I | 102,500 SF on about 12 acres in the Trinity Hills area of north Nashville, broken ground 4 September 2025 and due to open in 2026. The largest colocation facility in Nashville proper when it completes. Critical power |
Both rows predate the rule that now governs them. On 21 July 2026 the Metro Council unanimously passed Nashville's first data center zoning framework together with a temporary moratorium on accepting, processing or issuing zoning, building and grading permits for data centers in Davidson County. The framework bans data centers above 500,000 square feet outright, confines the rest to heavy industrial land, requires a special exception hearing, and imposes buffers around homes, schools, hospitals and the zoo. The DC BLOX site next to the zoo is what prompted it. Read anything announced in this county before that date as subject to a process that has since changed. Read the reporting.
Announced capacity is collected by hand from trade reporting and company statements, and each figure links to the report it came from. It is kept apart from the permit record above and never added to it: one is a document a jurisdiction issued, the other is a plan a company published. Neither is availability.
Where the multi-tenant buildings actually are
Downtown and the Gateway corridor
The carrier-facing end of the market, and the right starting point when the requirement is network led or when latency to the city itself matters. Expect enterprise-scale rooms rather than large blocks, and expect the network advantage to be the reason you are paying for the address.
The southeast corridor
Between the airport and the Brentwood office belt, which is where a good deal of the metro's purpose-built colocation sits and where Flexential holds a position. Suburban floor plates, easier loading and parking, and a straightforward drive from most of the corporate campuses south of the city.
Antioch and the southern suburbs
Cheaper land inside Davidson County, which is where newer multi-tenant development in the city has tended to land. Worth testing when the requirement is production capacity rather than interconnection, and worth asking about delivery dates rather than assuming them.
Rutherford, Williamson and Wilson counties
Outside Nashville Electric Service and generally inside a cooperative, which changes the retail tariff and sometimes the answer on large loads. This ring is where campus-scale proposals in Middle Tennessee tend to go, and almost none of that is leasable colocation.
When Nashville is right, and when it is the wrong choice
Nashville is the right answer for a Middle Tennessee business, and it is a particularly good answer for a healthcare organisation that wants regulated workloads in a building its own staff can reach. It is a credible recovery site for a primary in Atlanta, Chicago or Dallas, and the hazard profile supports that argument rather than undermining it.
It is the wrong choice if you need depth of supply or depth of network. The multi-tenant inventory is thin enough that two operators declining a requirement can end a search, and the interconnection ecosystem is not in the same class as the markets that exist to serve networks. It is also the wrong market in which to assume that a large announced project nearby will loosen anything for you: capacity built for one tenant does not become colocation, and in this territory it may well tighten the local utility's position rather than ease it.
Establish the local power company and the retail schedule before you discuss anything else, because in TVA territory that is the fact that fixes your cost and it is building specific. Ask whether the operator's power recovery is metered, committed or blended, and ask what happens if TVA's wholesale rate moves during your term, since that pass-through is the mechanism through which a federal board's decision reaches your invoice. Ask what is energised in the room you are being shown today rather than what the building is designed for. If you are being offered space outside Davidson County, ask the utility question again from scratch, because the answer changes at the county line. And test growth honestly: ask what the operator can add in the same room in eighteen months, not what the campus could theoretically support.
