|Table 4.13. Fuel-Switching Capacity of Operable Generators: From Natural Gas to Petroleum Liquids,|
|by Type of Prime Mover, 2012 (Megawatts, Percent)|
|Prime Mover Type||Number of Generators||Net Summer Capacity||Fuel Switchable Net Summer Capacity Reported to Have No Factors that Limit the Ability to Switch to Petroleum Liquids|
|All Fuel Switchable Prime Movers||1,880||129,604||37,510|
|Notes: Petroleum includes distillate fuel oil (all diesel and No. 1, No. 2, and No. 4 fuel oils), residual fuel oil (No. 5 and No. 6 fuel oils and bunker C fuel oil), jet fuel, kerosene, petroleum coke (converted to liquid petroleum, see Technical Notes for conversion methodology), waste oil, and beginning in 2011, synthetic gas and propane. Prior to 2011, synthetic gas and propane were included in Other Gases.
In 2011, EIA corrected the NAICS codes of several plants which resulted in a net capacity shift from the electric utility sector to the commercial sector.
