Thirty-five Years of Renewable Energy Project Experience at Fort Huachuca, AZ
Fort Huachuca, Arizona, located 60 miles (96 km) southeast of Tucson, has had 35 years of experience with various renewable energy systems. This article discusses lessons learned from the successes and failures over the past 35 years, including: an indoor pool solar water heating system installed in 1980; a solar domestic hot water system installed in 1981; a grid connected photovoltaic (PV) system installed in 1982; transpired air solar collectors (Solarwalls™) installed in 2001; daylighting installed in 2001; a 10-kW wind turbine installed in 2002; a 1 MW wind turbine installed in September 2011; PV powered outdoor lighting installed in 1994; a prototype Dish/Stirling solar thermal electric generator installed in 1996; two 30-kW building integrated photovoltaic systems installed on new membrane roofs in January 2009; a 42.84 kW photovoltaic system that was moved from the Pentagon in June 2009 and was operational in early November 2009 on a truck shed roof at Fort Huachuca; and a utility owned 13.6 MW (AC) photovoltaic system installed in 2014. Also discussed is an experimental solar attic system that collects the hot air in an attic and uses a heat exchanger and tank to produce solar domestic hot water. This article discusses the design, installation, metering, operations, and maintenance of these systems, and also work in progress on the installation of commercial, off-the-shelf 3-kW Dish/Stirling solar thermal electric generators and solar thermal/natural gas-to-electric systems at a central plant. Discussions also include biogas (methane from a wastewater digester) and biomass (a wood chip boiler) recently installed at a central heating/cooling plant.
