Power & ratepayers

Every megawatt figure about a data center sits over a denominator, and that denominator is somebody's grid. A real impact study names the grid and cites the source. It then states what the campus load does to the households on the same wires.

Whose grid this is

What those systems already carry

The disclosed campus draws ~148 MW — at a 0.9 load factor, ~1,166 GWh/yr, the numerator of every share above. The draw is itself an [inference].

The campus against consumer prices

The demand → consumer-price read needs an instrument-grounded campus load — an air permit or a filed disclosure. This site's load is a screening bracket, so the read is withheld rather than computed off an inference — the gap panel below names the instrument that would ground it.

• Grid foundation layer (#94). The state, Dayton Power & Light Co, and PJM denominators are now all connector-sourced — Ohio retail from EIA (shared with #91), per-utility retail from the EIA-861 file, and PJM annual demand from EIA-930. The campus is a single load equal to a material fraction of its serving utility's entire retail sales. Denominator vintages differ (utility EIA-861 2024 / BA EIA-930 2024 / state EIA 2025 (1-year spread)): the EIA state seriesid route publishes ahead of the EIA-861 bulk file and the EIA-930 annual sum, so the three shares are not struck against one common year.

The cited service chain with its full citations, the cohort-price qualification, and the load report's inference chain are in the grid annex.
