20 Palo Verde By the Numbers Initial construction permit May 1976 Began commercial operation Unit 1: January 1986 Unit 2: September 1986 Unit 3: January 1988

21 Palo Verde By the Numbers Largest power generator in the U.S. Total output 4,030 net megawatts Meets the electrical needs of approximately 4 million people around the clock

22 Palo Verde By the Numbers For the same electrical generation from solar or wind, you would need approximately: 125 square miles of photovoltaic panels or parabolic troughs (about the size of Mesa) 531 square miles for wind generators (about the size of Phoenix and Glendale combined) Sources: Global Energy Decisions, U.S. Department of Energy, Electric Power Research Institute

23 U.S. Electricity Production Costs , In 2008 cents per kilowatt-hour Costs Coal Gas Nuclear Petroleum Production Costs = Operations and Maintenance Costs + Fuel Costs. Production costs do not include indirect costs and are based on FERC Form 1 filings submitted by regulated utilities. Production costs are modeled for utilities that are not regulated.

31 Conserving Water Unlike other sites, Palo Verde has no lake, ocean or river so recycled wastewater is utilized City of Phoenix s 91st Ave Wastewater Treatment Facility Tolleson Wastewater Treatment Facility

32 Conserving Water Palo Verde s Water Reclamation Facility can recycle up to 90 million gallons of wastewater daily Average daily cooling water usage during the summer is 80 million gallons Average daily water usage for the year is 65 million gallons This is about the same total cooling water use as a coal-fired power plant per megawatt-hour

38 Transporting New Fuel Prior to each refueling outage, fuel assemblies are delivered by truck One fuel assembly per canister About 10 canisters per truck truckloads Following inspection, new fuel assemblies are stored in the Fuel Building

39 Used Fuel Storage Fuel assemblies are removed from the reactor and moved under water into the used fuel pool and stored in racks.

40 On-Site Dry Fuel Storage Palo Verde Goal: Always have full core offload capability Spent fuel pools have reached maximum capacity Established additional dry fuel storage facility Fuel is sealed inside leak-tight steel canister Steel canister inside concrete cask Casks sit on concrete pads outdoors Storage facility has full security measures
