Industrial retail rate

6.7¢/kWhState-level EIA-861 industrial average. The map colours by this, not by a per-county rate.

Per-utility rates in county

5 of 6 serving utilities: 6.4 to 7.6¢/kWhLowest to highest industrial rate among the utilities serving this county (EIA-861 Sales to Ultimate Customers). A spread, not the county’s rate, and it covers only the serving utilities that report one.

Interconnection queue

2 projects, 360 MW

Proposed generation

183 MW planned or under constructionUnits filed with EIA as planned or under construction (Form EIA-860M). Declared intent from the federal inventory, not the interconnection queue and not guaranteed capacity.

Grid carbon intensity

982 lb CO2/MWh

Water withdrawals

11 Mgal/dAll uses, freshwater. Water already withdrawn locally, not water available for a new load.

Construction labor near site

35,505 employed in construction within ~120 km (22 of 25 counties reporting)A large build needs hundreds of skilled construction workers on site for one to three years. A county with few of them within commuting range means bussing crews in, per diem, and housing, which is real cost and schedule risk. This counts people employed in construction within about a 120 km drive (BLS QCEW), summed across nearby counties. It is not labor known to be available: most are already committed to other projects, and no public data reveals who is free.
