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.

PWR = Pressurized Light Water Reactor.
Note: Totals may not equal sum of components due to independent rounding.
Source: Form EIA-860, "Annual Electric Generator Report," and Form EIA-923, "Power Plant Operations Report."

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.
