Industrial retail rate

8.9¢/kWhState-level EIA-861 industrial average. The map colours by this, not by a per-county rate.

Per-utility rates in county

6 of 8 serving utilities: 6.2 to 9.2¢/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

15 projects, 2,921 MW

Proposed generation

1,432 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

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 Water already withdrawn locally, not water available for a new load.

Construction labor near site

40,970 employed in construction within ~120 km (23 of 24 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 Portage

Below, Portage in Wisconsin is described from public data as a starting point for siting diligence. Portage reaches 345 kV, a high-voltage transmission class, at its strongest mapped point of grid access. With 20 substations mapped, Portage has a moderate spread of interconnection points.

Portage falls inside the MISO market (Midcontinent Independent System Operator), which governs how its interconnection requests and capacity move. The rate for Portage is the 8.9 cents per kWh state industrial average (EIA-861), the same figure the map colours by. Across Portage, reported per-utility industrial rates cover 6 of 8 serving utilities: 6.2 to 9.2¢/kWh, offered only as context beneath the state figure.

Portage has 15 interconnection-queue projects on record, totalling 2,920.53 MW of requested capacity. Portage has 1,432 MW of planned or under-construction generation on file in EIA-860M. The balancing authority covering Portage carries a grid carbon intensity of 981.982 lb CO2 per MWh in eGRID.

Reported freshwater withdrawals for all uses in Portage are 79.79 million gallons per day in the USGS 2015 compilation, existing demand rather than water free for a new load. Around Portage, some 40,970 people work in construction within about a 120 km commute (BLS QCEW), a measure of reach, not of available crews.

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