Where the fields line up
3 shared fields — join on these.
| Field | OpenEI energy data | data.gov federal open data catalog |
|---|---|---|
title | Human-readable dataset name in the catalog record - the primary triage key when a query returns hundreds of DOE submissions. | Dataset title as published by the source agency - the primary human-readable key for triage. |
description | Abstract describing what the submission contains and how it was produced, written by the publishing program. | Dataset abstract as written by the publishing program, usually stating method, vintage and intended use. |
license | The publishing program's own usage declaration for the submission, normalized during delivery so rights resolve through your Datadory agreement. | Usage declaration stated by the publishing agency where one applies; normalized during delivery so usage rights resolve from your Datadory agreement. |
Coverage, side by side
| OpenEI energy data | data.gov federal open data catalog | |
|---|---|---|
| Geographic | Primarily United States - national, state, county and site level - plus some global resources such as country-level wind supply curves | United States across federal, state, county and city publishers, with occasional global-extent records |
What each contains
Pick by fit, not by loyalty.
| OpenEI energy data | data.gov federal open data catalog | |
|---|---|---|
| Publisher | NREL / US DOE Open Energy Information (Open Energy Data Initiative) | data.gov / US GSA |
| Subject | DOE-program energy datasets: grid and power-systems studies, storage, load profiles, renewables siting | Government-wide discovery index spanning federal agencies plus state, county and city publishers |
| Records | About 2,591 catalog records out of roughly 2,821 advertised submissions from 300-plus providers | 552,271 indexed datasets as of August 2026 |
| Volume behind the catalog | 4.8 petabytes of files, more than 123 million downloads | Set by each publishing agency; every record points upstream to its owner |
| Geographic coverage | Primarily United States - national, state, county and site level - plus some global resources such as country-level wind supply curves | United States across federal, state, county and city publishers, with occasional global-extent records |
| Field dictionary | 11 documented columns, definitions verified | 14 documented columns, definitions verified |
| Formats | CSV, Parquet, JSON, HDF5, PDF, GeoTIFF | JSON, CSV, XML, XLSX, ZIP, HTML |
| Best for | Power-systems modeling, load profiling, storage research, renewables siting | Cross-agency discovery: emission factors, patents, manufacturing programs, municipal records |
Or take both in one feed
Yes - as spine and net rather than as substitutes.
Build the energy-domain spine from OpenEI's curated collections: load profiles, grid studies, siting and storage data in one coherent shelf. Then sweep data.gov for what DOE does not publish - NAICS-6 emission factors for supply-chain carbon work, patent records tracing component innovation, state and municipal records the initiative will never carry. Because NREL collections appear in both catalogs - SMART-DS synthetic network models and the wind turbine gearbox benchmarking data are visible from either side - reconcile the overlap on persistent identifiers, most of which are DOIs, before counting anything twice.
One caution from the records: data.gov's relevance ranking mixes patent noise into topical queries, so filter on organization and theme before drawing conclusions from hit counts. And expect asymmetric depth - a data.gov hit on a grid study resolves to the same files OpenEI catalogs natively, while the reverse trip lands you in a much larger, much flatter index.
Or take both in one feed: Datadory delivers them alongside the rest of the 22-record Electrical Components & Equipment slice, normalized to their documented field dictionaries and validated against sample rows, on the schedule your team sets - daily, weekly, or hourly.

Fair questions
Is OpenEI energy data better than data.gov federal open data catalog?
Different instruments, so better depends on the question. For DOE-published energy work - roughly 2,591 curated records covering grid studies, storage, hourly load profiles and renewables siting, backed by 4.8 petabytes - OpenEI wins outright. For cross-agency discovery across 552,271 US government datasets, data.gov does. Both clear the 7.81 catalog average; sample both, pick by fit.
Do OpenEI energy data and data.gov federal open data catalog contain the same datasets?
Partly. Both publish DCAT-US metadata, and NREL material surfaces in both - SMART-DS synthetic electrical network models and wind turbine gearbox benchmarking data are reachable from either catalog. The overlap reconciles on persistent identifiers, usually DOIs; outside DOE-published energy data the two barely intersect.
Which is bigger, OpenEI energy data or data.gov federal open data catalog?
Depends on the axis. By catalog records, data.gov: 552,271 indexed datasets as of August 2026 against roughly 2,591 OpenEI records - about two orders of magnitude. A big index and a deep one.
What fields do the two dictionaries share?
A DCAT-US spine: title, description, keyword tags, publisher organization, a modification date, a persistent identifier that is usually a DOI, and distribution entries carrying file format and media type. OpenEI documents 11 columns; data.gov documents 14, adding bureau and program codes, a contact point, a popularity score and a second catalog-checked timestamp.
Can I get both OpenEI energy data and data.gov federal open data catalog from Datadory?
Yes - sample both and pick by fit, or take both in one feed. Datadory normalizes each to its documented field dictionary (11 columns on the energy side, 14 on the federal index), attaches sample rows for validation, and ships them next to the rest of the 22-record electrical components & equipment slice, delivered daily, weekly, or hourly.
