The grid, as it stands.
Live conditions across 8 grid operators. Every utility-scale US power plant, mapped by fuel and by state. Every data centre on record. And close readings of the interconnection rules that decide what gets built.

What this site is
Four datasets, one grid
Each one carries the date it was last updated on every page.
Directory
Every US power plant
The full 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
- Operating plants
- 14,659
- Planned projects
- 1,595
Directory
Data centres, honestly counted
No complete roster of US data centres exists. This is every facility on record, labelled row by row, and presented as a floor rather than a census.

The rules, read closely
Interconnection is where projects die, and the rules live in filings nobody outside the docket reads. Each piece is a close reading of the rules themselves.

What the filings actually say
Close readings of the orders, tariffs and rules that decide interconnection.
ERIS vs NRIS: which interconnection service should your project request?
Neither service conveys transmission service. The difference is whether your plant gets studied — and upgraded — so it can be designated a Network Resource.

The 2025 allocation cycle slid a year. There is no 2026 TPD allocation, and Cluster 15 cannot seek deliverability until March 2027.

A $2.24bn premium that narrows to $1.35bn, 1,400 fewer rebuild miles, and roughly $230m a year in consumer energy savings.
