|Table 4.11. Fuel-Switching Capacity of Operable Generators Reporting Natural Gas as the Primary Fuel, by Producer Type, 2011|
|Fuel-Switchable Part of Total|
|Producer Type||Total Net Summer Capacity of All Generators Reporting Natural Gas as the Primary Fuel||
Net Summer Capacity of Natural Gas-Fired Generators Reporting the Ability to Switch to Petroleum Liquids
|Fuel Switchable Capacity as Percent of Total||Maximum Achievable Net Summer Capacity Using Petroleum Liquids||Fuel Switchable Net Summer Capacity Reported to Have No Factors that Limit the Ability to Switch to Petroleum Liquids|
|Independent Power Producers, Non-Combined Heat and Power Plants||176,517||41,890||23.7||40,935||11,468|
|Independent Power Producers, Combined Heat and Power Plants||29,373||6,891||23.5||6,614||1,239|
|Electric Power Sector Subtotal||399,520||125,623||31.4||122,829||37,814|
|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.
