| Generator | Technology / statusWhether a generator or project is operating, planned, on standby or retired, as its source reports it.Definition ↗ | NameplateA generator’s rated maximum power, in MW. Capacity is a rating, not how much electricity it produced.Definition ↗ · MW | Ownership basisHow a generator's owners were established: from EIA-860's ownership schedule (reported), from EIA's rule that a unit absent from a complete schedule is wholly owned by its operator (derived), or unknown.Definition ↗ |

None of this plant’s units is in EPA’s continuous monitoring programme for this year, so no CEMS data exists for it. That is not a claim of zero emissions: units outside the programme file nothing here. Source
No confirmed status or capacity changes among comparable units. Missing monthly assertions and units outside the baseline have no like-for-like comparison.
