Note: All values in this chart are an approximation of the fuel consumption of a “generic”
natural gas generator based on the size of the generator and the operating load being placed
on it. Actual consumption may increase or decrease based on multiple factors such as the
equipment brand/manufacturer specifications, fuel quality, equipment condition, and
individual operating environment. Consumption of natural gas can be converted to other
common units by taking (X) cu.ft./hr. * 1031 BTU / cu.ft. (natural gas) = BTU/hr * 0.00001 =
therms/hr
