FinalPreliminary

Capacity factor by year

Net MWh ÷ (summer MW × hours), primary-fuel 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.

Heat rate applies to fuel-burning (thermal) units only.
