Active plants currently in the public catalog.
Trust
Current sources and data freshness
The site is built from imported public datasets rather than scraped marketing copy. The source vintages below reflect the database currently deployed to the public app.
Emissions can lag plant and generation vintages because EPA eGRID and EIA releases do not move in lockstep.
Nationwide ZIP centroids available for canonical near pages.
Plant and generator inventory vintage loaded in the app DB.
Emissions vintage loaded in the app DB.
Official datasets
Each public page type is backed by a specific source family.
EIA Form 860
16,132 rows
Federal plant and generator inventory used to define which plants exist and how they are structured. Plant identity, location, generator rows, operating status, sector, and ownership context. Public plant pages are filtered to active plants after import.
2024EIA Form 923
17,964 rows
Federal generation and fuel consumption reporting. Annual generation totals and fuel mix composition on plant and browse pages. Generation rows are not a one-to-one match with public plant pages; they aggregate reported fuel lines.
2024EPA eGRID
12,612 rows
EPA plant emissions and intensity dataset. CO2, SO2, NOx, and CO2-rate context on plant and nearby pages. eGRID typically lags EIA plant and generation vintages, so emissions can be one release behind.
2023GeoNames US postal codes
41,488 rows
ZIP centroid table for nationwide near-page coverage. Canonical `/near/{zip}` pages and fallback resolution for location search. Distance calculations are ZIP-centroid estimates, not rooftop measurements.
2026How they map into the site
Each dataset does a different job in the page model.
These source families are joined by plant code where possible. When they disagree or one source is missing for a plant, the site favors showing a partial but honest page over inventing a complete one.
Defines plant identity, plant location, generator inventory, sector, and ownership context.
Provides generation and fuel totals that shape plant pages and browse-page mix bars.
Provides emissions totals and intensity where EPA data is available for the plant code.
Provides nationwide search coverage and canonical ZIP-based near-page routing.
Freshness caveats
A newer page is not always a newer fact for every field on that page.
EIA Form 860 and EIA Form 923 are both annual releases, but they cover different concepts. EPA eGRID is also annual and may trail the latest EIA cycle. The site currently reflects that reality instead of backfilling fake estimates.
The current public catalog is filtered to active plants, so source row counts and public page counts are not supposed to match exactly.
Raw generator detail imported for the current plant vintage.
Ownership shares imported for the current plant vintage.
Fuel-level generation rows in the current generation vintage.
