aCapacity factors are a measure of how often electric generators operate over a specific period of time,
using a ratio of actual output (net generation) to the maximum possible output over that same time period
(using time-adjusted capacity). A small number of operating generators can lead to volatile capacity factor
values, including capacity factors exceeding 100%.
— = Not applicable.
bUsage factors are a measure of how often electric generators operate over a specific period of time,
using a ratio of actual output (gross generation) to the maximum possible output over that same time period
(using time-adjusted capacity).
Where shown, (s) = Percent value less than 0.05.
cDistillate fuel oil, residual fuel oil, petroleum coke, jet fuel, kerosene, other petroleum, waste oil, and
propane.
Note: Data are for utility-scale facilities only.
dWood and wood-derived fuels, municipal solid waste from biogenic sources, landfill gas, sludge waste,
agricultural byproducts, and other biomass.
