FinalPreliminary
Capacity factor by year
Net MWh ÷ (summer MW × hours), gas/coal/oil units. Each year uses that year's EIA-860 ratings; the hollow dot is the latest 12 months.
Heat rate by year
Electric fuel MMBtu × 1000 ÷ net MWh (Btu/kWh, HHV), fossil units only; CT + CA counted as one combined-cycle block.

Fuel capability
Gas-fired turbines (CT/GT/CA/CS) that can also burn liquid fuel. EIA-860 Schedule 3 for capability, EIA-923 for actual burn.
StatusLikely still dual fuel

Time gas → oilup to 6 h (EIA 6H)
Time oil → gasup to 6 h (EIA 6H)
⚠ EIA-860 vs 923: 923 shows liquid fuel burn but 860 reports 0 MW net summer capacity on oil.
Generators
EIA-860 (annual) with EIA-860M updates through Sep 2026. EIA-923 reports generation by plant, prime mover and fuel, not by unit, so unit-level output isn't shown.
