2 14 MW power plant at the Nellis Air Force Base (south Nevada). ~30 million kilowatt-hours (30MWh) of electricity annually. Expected to reduce carbon dioxide emissions by 24,000 tons/year. Contraction cost: $100 million. Land: 140 acres (570 dunam). The company that owns the panels is leasing the land at no cost, and Nellis is agreeing to buy the power for 20 years at about 2.2 cents/kWh, instead of the 9 cents they are paying to Nevada Power, saving the Air Force $1 million each year. None of the $100 million cost came from the Air Force. North America’s Largest Solar-Electric Plant Switched On (28/12/2007) The Need/Challenge: 10TW Renewable Energy
