Power by county

Tennessee: data center power by county

Browse the 95 counties in Tennessee with a data center power and grid screening profile. Compare substation counts and highest grid access voltage by county, then open a county for its full outlook.

State overview

Counties with a profile: 95 counties
Industrial retail rate (state industrial average): 6.7¢/kWh

The industrial retail rate is a state industrial average and applies to every county below. The per county figures are substation count and highest grid access voltage, which do vary by county.

Map

The same county map as the national page, framed to Tennessee. Switch layers to compare substations, grid access voltage, and more; the color scale is the national one, so a county reads the same shade here as nationally. Click a county to open its profile.

How to read this

Each color is one measured quantity for that county, shown so you can read it and judge for yourself. Click a county, or choose one from the picker, to open its panel. The color scale is the national one, so a Tennessee county reads the same shade here as on the national map.

OverlayExisting data centers

Where data centers already stand. Off by default, and shown purely as background: the markers are context a reader can weigh, and this map draws no conclusions from them.

OverlayFreight rail

In-service freight mainline, the track heavy equipment like transformers and generator sets actually moves over. Off by default and shown purely as background: whether a line runs near a specific site is something to read off the map for yourself, not a judgment this map makes for you.

Sort by any column to browse. The order is a view of the data, not a ranking, and the list opens alphabetically by county. Select a county for its serving utilities, market, interconnection queue, and sources.

What this is

These are screening-grade grid profiles for Tennessee, describing the public power picture around each county rather than any specific parcel. They are a starting point for siting diligence, not a substitute for an interconnection study. To screen a specific address, run it through the site tool.
