nameplate capacity

nameplate capacity is generator's rated maximum output, the attribute that sets Form EIA-860's 1 MW reporting threshold and drives the tens-of-thousands-row operable generator sheet covering the entire US fleet above that cutoff. In Datadory's catalog of 1,744 datasets, EIA Form EIA-860 coverage and estimated_size are working examples.

What is nameplate capacity?

A generator's rated maximum output, the attribute that sets Form EIA-860's 1 MW reporting threshold and drives the tens-of-thousands-row operable generator sheet covering the entire US fleet above that cutoff.

In this catalog it appears concretely: - EIA Form EIA-860 coverage — "every plant at or above 1 MW nameplate". - estimated_size — "the Operable generator sheet alone carries tens of thousands of rows covering the entire US fleet above 1 MW".

estimated_size is the second reference point worth knowing: "the Operable generator sheet alone carries tens of thousands of rows covering the entire US fleet above 1 MW". Reading the two together shows how much variation sits underneath one shared label.

Why does nameplate capacity matter when choosing a dataset?

A table is only as good as the column you actually need. If this field is absent, sparsely populated or defined inconsistently across rows, no amount of surrounding richness rescues the analysis, so it deserves its own line in your evaluation checklist.

The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and EIA Form EIA-860 coverage lets you inspect the real artifact before any budget is committed.

How do you evaluate nameplate capacity in a data source?

Treat every claim of this attribute as testable:

  1. Open EIA Form EIA-860 coverage and confirm its record — "every plant at or above 1 MW nameplate" — against the files you actually receive.
  2. Open estimated_size and confirm its record — "the Operable generator sheet alone carries tens of thousands of rows covering the entire US fleet above 1 MW" — against the files you actually receive.

Frequently asked questions

What is an example of nameplate capacity?

EIA Form EIA-860 coverage is the clearest example in this catalog. Its record states: "every plant at or above 1 MW nameplate". Across all 1,744 datasets Datadory averages a quality score of 7.81 out of 10, so a named example can be weighed rather than trusted blindly.

Is data described as "nameplate capacity" free to use?

Treat access and permission separately. 82.4% of the 1,744 datasets in this catalog are free to access, but 235 are freemium and 61 are paid outright, so confirm both the price and the license on the exact distribution before building on it.

How do I verify a source really provides nameplate capacity?

Open EIA Form EIA-860 coverage next to estimated_size and compare the promise with the download. Field definitions are verified for 1495 of 1,744 datasets (85.7%), which makes that check fast inside the catalog and manual outside it.
