State Profile and Energy Estimates

Changes to the State Energy Data System (SEDS) Notice: In October 2023, we updated the way we calculate primary energy consumption of electricity generation from noncombustible renewable energy sources (solar, wind, hydroelectric, and geothermal). Visit our Changes to 1960—2022 conversion factor for renewable energy page to learn more.

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.

dWood and wood-derived fuels, municipal solid waste from biogenic sources, landfill gas, sludge waste,
agricultural byproducts, and other biomass.
