| Rumored | Former DP&L Hutchings Power Station site Miamisburg, Montgomery County, Ohio |
The City of Miamisburg says its nine-month data center moratorium, adopted Sept. 1, 2026, came after community concerns that a large-scale data center could be built at the site of the former DP&L Hutchings Power Station. The city says the property was bought in 2021 by Frontier Industrial Corp., a Buffalo-based developer. No developer or application for a data center is named; the city describes it as a potential development. What the sources say“The moratorium follows community concerns surrounding the potential development of a large-scale data center at the former DP&L Hutchings Power Station.” — City of Miamisburg, OH |

| Approved | Spalding Investments data center campus Spalding Investments, LLC Griffin, Spalding County, Georgia |
Spalding County commissioners approved rezonings and special exceptions with conditions in October 2025 for a data center campus by property owner and developer Spalding Investments, LLC on 127.45 acres bordered by High Falls Road, South McDonough Road and Highway 16/Arthur K. Bolton Parkway. The developer first proposed eight two-story buildings and later reduced them to six, totaling 1.42 million sq ft, because of the flight path of the new Griffin-Spalding County Regional Airport. DatacenterDynamics (January 2026) still describes eight two-story data centers; the Griffin Daily News reports the redesign to six buildings with the same total floor area. In August 2025 the developer's attorney gave an estimated value of $1.5 billion, including computers, and a closed-loop 16,000-gallon water system. Not the same project as Project Spalding (Montana Property Group LLC, 132.9 acres, approved July 2025), which is a Census record. What the sources say“In June, the Spalding County Planning Commission recommended approvals of a proposed rezoning and special exception for an 8-building data center campus on 127.45 acres bordered by High Falls Road to the north, S. McDonough Road to the east, and Hwy. 16/Arthur K. Bolton Parkway (AKB) to the south.” — The Griffin Daily News “Rezonings and special exceptions with conditions for the second data center campus were approved by commissioners in October.” — The Griffin Daily News “Spalding Investments LLC had filed to develop eight two-story data centers on 127 acres in Griffin, while Montana Property Group LLC's Project Spalding campus could total 2.55 million square feet (236,900 sqm).” — DatacenterDynamics “Spalding Investments, LLC, the property owner and developer, is building six two-story data centers on the property for a total of 1.42 million square feet.” — The Griffin Daily News |

Stages use the Census definitions: rumored means land deals or reports of interest with no formal application; proposed means an application, a rezoning request or a public announcement of a specific site. Dates are each source’s publication date. Checked Oct 23, 2026. Entries report what the cited sources have published; they are not confirmation that any company plans a project, and many early-stage proposals never proceed.
Why the Census counts so few rumored projects
The Census currently lists 6 rumored projects. That is not a count of every early-stage data center plan in the country. A project enters the Census only once it can carry a full record, and most rumors never get there: the company is often unnamed, local officials may be under a nondisclosure agreement, and the first public trace is a land deal or a moratorium vote rather than an application.
The watchlist exists so those projects are not invisible in the meantime. It uses the same stage definitions, a lighter evidence standard, and keeps its entries separate so the Census’s own figures stay comparable over time.
The watchlist: common questions
Why aren’t these projects in the Census?
A Census record needs several reliable sources and a sourced value for every fact it shows. Early-stage projects rarely have that: developers work under code names and nondisclosure agreements, and the first public sign is often a land purchase, an annexation vote or a moratorium. The watchlist records what can be documented now, to a lighter standard, and says so.
What does it take to get on the watchlist?
A specific project (a named developer or a specific site) and either one government record describing it, or two independent sources, which can be two news outlets or one news outlet plus the developer itself. Every entry quotes each source.
When does an entry move into the Census?
When it meets the Census standard: enough reliable sources to build a full record with a sourced timeline. Entries are removed if the reporting turns out to be wrong.
