Notes: 'Associated Net Summer Capacity' is defined as the net summer capacity of the generators that are associated with the operation of this environmental equipment. In some cases respondents have reported equipment late. Counts and capacity may have changed from prior publications of this table because of late reporting. Coal includes anthracite, bituminous, subbituminous, lignite, waste coal, refined coal; and coal-derived synthesis gas. Petroleum Liquids includes distillate and residual fuel oils, jet fuel, kerosene, waste oil, and beginning in 2011, propane. Petroleum Coke includes petroleum coke-derived synthesis gas. Other Energy Sources consists of wood and wood waste products, biomass, blast furnace gas and Other Fossil Gas. Source: Form EIA-860, "Annual Electric Generator Report." |
