Gross output of plants with a stake
17 of 18 plantsOutputGross: each plant's whole output, whatever the stake. Equity share: each plant's output times the stake.Covers 17 of 18 plants with a stake: US plants with an EIA monthly series.under 1% of the output is from 16 plants recorded as wholly owned.15 plants: operator, wholly owned per EIA-860.Not included: 3 plants it operates without a recorded stake.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.
