- Proposed generation
- 17 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
- 716 lb CO2/MWh
- Water withdrawals
- 33 Mgal/dAll uses, freshwater. Water already withdrawn locally, not water available for a new load.
- Construction labor near site
- 246,202 employed in construction within ~120 kmA 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.
