A public-private partnership has helped one Air Force base reduce its energy costs and convert to 25 percent renewable energy. Nellis Air Force Base, just north of Las Vegas, took a big step in 2007 when it installed a 14.2-megawatt, 70,000-panel photovoltaic solar array that reduced carbon dioxide emissions by 24,000 tons a year. Built partly on a landfill, the field of solar panels takes advantage of two resources plentiful in Nevada: sunshine and empty land.
At its unveiling in December of 2007, the Nellis array was the largest solar panel installation in North America. (It has since been eclipsed by a Florida Power & Light plant.) The project was originally expected to produce about 30,000 megawatt-hours of electricity per year, but Steven Dumont, Air Combat Command Energy Manager, says it’s actually producing closer to 32,000 megawatt-hours, which is about 8 percent above expectations.
“It all started with a developer who called the base and subsequently called us at Air Combat Command,” he said. “[They] said, ‘We have an idea if you’re willing to give us the land. We can make it cost-effective.’”
