Highest grid access

69 kV

Substations in county

17

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

7 of 10 serving utilities: 1.9 to 9.4¢/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

None on record

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

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 Water already withdrawn locally, not water available for a new load.

Construction labor near site

20,646 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.

Grid conditions in Lake

Everything here about Lake, South Dakota comes from public federal and state records, with the gaps left visible. The highest mapped voltage in Lake is 69 kV, a sub-transmission class that usually serves distribution rather than a single large load. With 17 substations mapped, Lake has a moderate spread of interconnection points.

Lake falls inside the SPP market (Southwest Power Pool), which governs how its interconnection requests and capacity move. The rate for Lake is the 8.7 cents per kWh state industrial average (EIA-861), the same figure the map colours by. Across Lake, reported per-utility industrial rates cover 7 of 10 serving utilities: 1.9 to 9.4¢/kWh, offered only as context beneath the state figure.

Across the covered feeds, Lake, South Dakota carries no interconnection-queue project, from either real quiet or a feed not yet loaded. EIA-860M lists nothing planned or under construction for Lake, South Dakota, which is a national filing and so a real zero. The balancing authority covering Lake carries a grid carbon intensity of 871.526 lb CO2 per MWh in eGRID.

Reported freshwater withdrawals for all uses in Lake are 2.11 million gallons per day in the USGS 2015 compilation, existing demand rather than water free for a new load. Around Lake, some 20,646 people work in construction within about a 120 km commute (BLS QCEW), a measure of reach, not of available crews.

These numbers for Lake are screening-grade context for the whole county, drawn from public data with the gaps left visible. Read the figures for Lake, South Dakota together rather than one at a time: grid access matters less without substations near it, and a quiet queue reads differently inside an organized market than outside one. The next step for Lake, South Dakota is an address-level interconnection study; the county figures here only narrow where to look. For Lake, South Dakota, the source log below records where each figure comes from and when it was pulled, keeping the provenance visible.
