Nashville TN / mayoral executive order / state preemption workaround / 5 MW threshold

Plain-English version: Nashville's mayor cannot legally declare a moratorium himself — Tennessee preempts that power at the state level. So instead of a ban, O'Connell signed an executive order (Executive Order 59) that does two things. First, it tells every city department — planning, water, codes, public health — to study how large data centers affect power use, water use, traffic, air quality, and neighborhoods, and to use whatever existing authority they already have to slow or condition those projects. Second, and more important politically, the order formally puts the mayor's office behind the separate moratorium ordinance already moving through Metro Council. An 'executive order' here is closer to a signal-and-coordinate document than a legal ban — but it removes any ambiguity about which way City Hall is leaning. The order defines a 'large' data center as anything over 20,000 square feet or more than 5 MW of electrical demand — a deliberately low threshold that catches almost every serious project. The trigger was a proposed data center near the Nashville Zoo that drew hundreds of residents to a Planning Commission meeting days earlier.
