Equity share: each plant's output times the stake.Covers 1 of 1 plant with a stake: US plants with an EIA monthly series.0% of the output is from 0 plants recorded as wholly owned.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.
