Live conditions across 8 grid operators. Every US power plant that reports on EIA-860M, mapped by fuel and by state. Every data centre with a citable public record. And close readings of the interconnection rules that decide what gets built.
What this site is
Each one is assembled from named public sources and carries its own as-of date on every page.
Live
Load, fuel mix, real-time prices and alerts for eight markets, copied from each operator's own published files. Where an operator publishes nothing, the page says so instead of showing a zero.
On the record
Directory
The EIA-860M operating inventory, split into fuel families and a page per state, with county, unit count, operating year and status on every plant. Planned projects are kept on separate pages so an operating count is never inflated.
On the record
Directory
No complete public roster of US data centres exists. This is the union of two open sources — county and city permit GIS, and OpenStreetMap — labelled row by row, and presented as a floor rather than a census.
On the record
Insight
Interconnection is where projects die, and the rules live in filings nobody outside the docket reads. Each piece is a close reading of named primary documents, with every figure traceable to one of them.
On the record
Power plants
EIA-860M for 2026-07. Each family has a national map and a page for every state that has one.
Most searched: nuclear power plants in the United States, nuclear power plants in Illinois, Texas wind farms.
Insight
Every number in these pieces is sourced to a FERC order, an ISO tariff, a state rule or a planning report, and linked.
Neither service conveys transmission service. The difference is whether your plant gets studied — and upgraded — so it can be designated a Network Resource.

Provenance
Grid operators’ own published files, EIA-860M, county and city permit GIS, OpenStreetMap, and the FERC, ISO and state-commission dockets the insight pieces read. Every page carries its sources and its as-of date above the fold.
Where a source publishes no capacity, no coordinate or no operator, the page shows a dash. Missing data is shown as missing rather than filled in, and a stale export is labelled stale.
All of this is assembled from open records. What the site adds is coverage, structure and provenance. Read what it does not contain.
