Arizona Nuclear Profile 2010 Arizona profile

Arizona total electric power industry, summer capacity and net generation, by energy source, 2010
Primary energy source	Summer capacity (mw)	Share of State total (percent)	Net generation (thousand mwh)	Share of State total (percent)
Nuclear	1,937	14.9	31,200	27.9
Coal	6,233	23.6	43,644	39.1
Hydro and Pumped Storage	2,937	11.1	6,831	6.1
Natural Gas	13,012	49.3	29,676	26.6

Petroleum	93	0.4	66	0.1
Total	26,392	100.0	111,751	100.0
¹Municipal Solid Waste net generation is allocated according to the biogenic and non-biogenic components of the fuel; however, all Municipal Solid Waste summer capacity is classified as Renewable. * = Absolute percentage less than 0.05. - = No data reported. Notes: Totals may not equal sum of components due to independent rounding. Other: Blast furnace gas, propane gas, other manufactured and waste gases derived from fossil fuels, non-biogenic municipal solid waste, batteries, chemicals, hydrogen, pitch, purchased steam, sulfur, tire-derived fuel, and miscellaneous technologies. Other Renewable: Wood, black liquor, other wood waste, biogenic municipal solid waste, landfill gas, sludge waste, agriculture byproducts, other biomass, geothermal, solar thermal, photovoltaic energy, and wind.

Operator: Arizona Public Service Company

Location: Palo Verde is located in Maricopa County, on a 4,050-acre site near Wintersburg, Arizona.

Construction Cost: Palo Verde units 1 and 2 cost $8.001 billion (2007 USD). Cost data for Unit 3 is not available.²

Reactor Descriptions: All three of the Palo Verde units are Westinghouse two-loop pressurized water reactors.

Cooling System: The plant uses reprocessed sewage water for its mechanical draft cooling towers.
