Highest grid access

161 kV

Substations in county

49

Industrial retail rate

10.1¢/kWhState-level EIA-861 industrial average. The map colours by this, not by a per-county rate.

Per-utility rates in county

2 of 5 serving utilities: 1.6 to 10.4¢/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

4 projects, 583 MW

Proposed generation

101 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

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 Water already withdrawn locally, not water available for a new load.

Construction labor near site

25,885 employed in construction within ~120 km (33 of 39 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 Jackson

Below, Jackson in Illinois is described from public data as a starting point for siting diligence. Jackson reaches 161 kV at its highest mapped voltage, a transmission class that can carry a substantial interconnection where capacity exists. With 49 substations mapped, Jackson offers interconnection points across many locations.

Jackson falls inside the MISO market (Midcontinent Independent System Operator), which governs how its interconnection requests and capacity move. The rate for Jackson is the 10.1 cents per kWh state industrial average (EIA-861), the same figure the map colours by. Across Jackson, reported per-utility industrial rates cover 2 of 5 serving utilities: 1.6 to 10.4¢/kWh, offered only as context beneath the state figure.

Jackson has 4 interconnection-queue projects on record, totalling 583.4 MW of requested capacity. Jackson has 101.3 MW of planned or under-construction generation on file in EIA-860M. The balancing authority covering Jackson carries a grid carbon intensity of 981.982 lb CO2 per MWh in eGRID.

Reported freshwater withdrawals for all uses in Jackson are 73.87 million gallons per day in the USGS 2015 compilation, existing demand rather than water free for a new load. Around Jackson, some 25,885 people work in construction within about a 120 km commute (BLS QCEW), a measure of reach, not of available crews.

These numbers for Jackson are screening-grade context for the whole county, drawn from public data with the gaps left visible. Read the figures for Jackson, Illinois 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 Jackson, Illinois is an address-level interconnection study; the county figures here only narrow where to look. For Jackson, Illinois, the source log below records where each figure comes from and when it was pulled, keeping the provenance visible.
