Industrial retail rate

8.7¢/kWhState-level EIA-861 industrial average. The map colours by this, not by a per-county rate.

Per-utility rates in county

4 of 10 serving utilities: 1.9 to 11.3¢/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

6 projects, 1,220 MW

Proposed generation

None on file (EIA-860M)Units 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

872 lb CO2/MWh

Water withdrawals

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 Water already withdrawn locally, not water available for a new load.

Construction labor near site

1,875 employed in construction within ~120 km (9 of 13 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.

Grid conditions in McPherson

Read on for the public power picture of McPherson in South Dakota, assembled for data center siting. At 345 kV, McPherson carries high-voltage transmission at its strongest mapped point. McPherson contains 10 mapped substations, a moderate footprint spread across the service area.

Wholesale activity over McPherson clears through the SPP market (Southwest Power Pool), whose footprint sets how interconnection requests and capacity are handled. McPherson carries the state industrial average retail rate of 8.7 cents per kWh from EIA-861, applied statewide. For McPherson, the per-utility spread is 4 of 10 serving utilities: 1.9 to 11.3¢/kWh, which qualifies but never replaces the state average.

The federal EIA-860M inventory files no planned or under-construction generation in McPherson, South Dakota, a real zero rather than a gap. In eGRID, the balancing authority over McPherson shows 871.526 lb CO2 per MWh.

For McPherson, the USGS 2015 compilation records 3.22 million gallons per day of all-use freshwater withdrawals, not water available to a new load. McPherson sits within commuting range of roughly 1,875 construction workers (BLS QCEW, about 120 km), most already committed elsewhere.

Every figure for McPherson here is screening-grade and describes the county as a whole, not any single parcel within it. None of the figures for McPherson, South Dakota settles a site on its own; each one qualifies the others, and all of them come from public federal and state datasets. Settling a site in McPherson, South Dakota requires a study of the specific parcel, a step beyond the county-level picture drawn here. Sources and data dates for McPherson, South Dakota are logged directly below, so each figure on this page can be traced back to its public dataset.
