USING THE FILES
legend.csv defines the columns, units, formats and blank-value meanings.
CSV is UTF-8 with headers. Import identifiers, ZIP codes and phones as text. Blank differs from zero or false.
LICENSES.txt contains source attribution and applicable notices.

LIMITATIONS
- Planned projects are reported intentions, not guaranteed builds or construction leads.
- A missing record or first appearance does not establish cancellation or project start.
- Annual ownership is a separately dated reference and does not identify current owners of every planned unit.
- Generator IDs are unique within plants; multiple generators at one plant are distinct records.
- Capacity MW and stored energy MWh measure different quantities; source missingness is preserved.
- Monthly facts describe report_month; annual reference tables describe their named year. Source blank cells remain blank. Code definitions and forms: https://www.eia.gov/electricity/data/eia860/ and https://www.eia.gov/electricity/data/eia860m/.
