Nameplate capacity, operating generatorsFull nameplate rating of the operating generators, before ownership shares. MW measures rated power; annual output is energy in MWh.Definition ↗
3,953.4MW
Source & method
Sum of operating nameplate MW over published plants whose reported balancing authority code is this BA; a reporting relationship, not a footprint
2024 inventory · reported · derived · valid · final
Net generationEnergy produced over the stated period after the plant’s own use, including signed storage output. Plant output is not allocated to owners or buyers.Definition ↗

1 plants with operating capacity have no EIA-923 row for the year; their output is unknown, not zero
EIA-930Hourly electricity demand, generation and interchange. Reported values are the authority’s filings. EIA-adjusted values account for non-physical commercial transfers; EIA-imputed values replace missing or anomalous reports with estimates. Every demand report EIA replaced is left out of every sum and mean here; a replaced generation or interchange report is left out when it is whose magnitude is at least 1.5 times the largest unreplaced magnitude of that authority and year, since zeros and imports are real there. The estimate is never used in its place.Definition ↗ reports for this authority, 2023-10 to 2026-09 (UTC months). Mean MW over the hours reported; a dot marks a month with under 90% of hours.
Reported demand; every hour EIA marked is left out and counted, and EIA's adjusted and imputed series are in the download table, never substituted here.

Display names and aliases (pipeline/config/crosswalks/aliases.csv)
Display names verified against each organization's own website; EIA legal names retained as aliases
A display name is the name an organization uses for itself; the EIA name stays searchable and on the record. Each row cites the page that shows the name.
