APS operates several jointly owned facilities - Four Corners Power Plant, Cholla coal plants and the Palo Verde Nuclear Generating Station.
* The Industry and APS emissions in pounds per megawatt-hour include nuclear generation. The industry average emission data for SO2, NOx, CO2, PM10, and VOC for the period 1999 to 2001 was obtained from emission trend summaries located on the EPA emission inventory Web site at: www.epa.gov/ttn/chief/trends/index.html. The 2002 average emission data is scheduled for release from EPA in May 2004.
The industry CO2 emission data was obtained from “Emissions of Greenhouse Gases in the United States, 2001,” DOE/EIA-0573 Dec, 2002. The report can be downloaded at: www.eia.doe.gov/oiaf/1605ggrpt/index.html. The annual industry generation data was obtained from Electric Power Monthly, December 2003, DOE/EIA-0226(2003/01).
