Gross output of plants with a stake

17 of 17 plantsOutputGross: each plant's whole output, whatever the stake. Equity share: each plant's output times the stake.Covers 17 of 17 plants with a stake: US plants with an EIA monthly series.60% of the output is from 11 plants recorded as wholly owned.11 plants: operator, wholly owned per EIA-860.Ownership as recorded today; each plant's output is its whole series. A plant's group is its technology; Unspecified fuel is EIA's "All Other", hydrogen, CHP with no fuel stated and plants with no technology on record.
