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.

Public plants 13,347

Active plants currently in the public catalog.

ZIP locations 41,488

Nationwide ZIP centroids available for canonical near pages.

Current EIA 860 2024

Plant and generator inventory vintage loaded in the app DB.

Current eGRID 2023

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.

2024

EIA 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.

2024

EPA 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.

2023

GeoNames 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.

How 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.

EIA Form 860 2024

Defines plant identity, plant location, generator inventory, sector, and ownership context.

EIA Form 923 2024

Provides generation and fuel totals that shape plant pages and browse-page mix bars.

EPA eGRID 2023

Provides emissions totals and intensity where EPA data is available for the plant code.

GeoNames ZIP centroids 2026

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.

Generator rows 34,855

Raw generator detail imported for the current plant vintage.

Ownership rows 5,496

Ownership shares imported for the current plant vintage.

Generation rows 17,964

Fuel-level generation rows in the current generation vintage.
