Renewable energy is a major focus for the U.S. Army Corps of Engineers. It reduces greenhouse emissions and dependence on fossil fuels. The Corps is using alternative energy like biofuel, wind power and geothermal. This renewable energy mix will provide 25 percent of the electricity used by the Corps.

Fort Buchanan wind turbine up, producing energy
By Debra Valine
The first of three 275 kilowatt wind turbines being erected on Fort Buchanan, Puerto Rico, is up and producing energy this week (April 19). The turbines are part of a large, multi-project renewable energy/energy reduction and Net Zero Water effort.
The U.S. Army Corps of Engineers, Engineering and Support Center, Huntsville, awarded a $34 million task order contract to Johnson Controls Government Systems, Milwaukee WI, on Dec. 22, 2012, to install wind power generation, solar photovoltaic systems, water conservation measures, and other energy conservation measures at Fort Buchanan.
Overall projected project savings is 37,867 MBtu and $2,606,258 per year. Renewable energy savings are projected to be 5,973 MBtu solar PV, domestic solar hot water 106 MBtu per year, wind power 3,244 MBtu per year, and water savings of 37,144,000 gallons per year.
While not the first wind turbine for the Army -- Tooele Army Depot has had a wind turbine since July 2009 -- it is the first for the Army under an Energy Savings Performance Contract (ESPC).
"This is a great project that has traditional energy conservation measures as well as renewable and water reduction," said Michael Norton, chief of Huntsville Center's Energy Implementation Branch.
An ESPC is a partnership between the Army and an energy services company. In consultation with the federal Government, the energy services company provides capital and expertise to make comprehensive energy and water efficiency improvements on facilities, or implements new renewable energy capability and maintains them in exchange for a portion of the generated savings.
This project supports President Barack Obama's directive that federal agencies use ESPC to make $2 billion worth of energy efficiency upgrades over the next two years, as well as supporting the Army's energy reduction goals of 30 percent energy and 15 percent water reduction by 2015.
"This project employs wind and water renewable technologies and serves as an outstanding example of combining several technologies that together result in substantial energy consumption and cost savings for the Army," said Lisa Harris, ESPC project manager for the Fort Buchanan ESPC project. "We are working with Anibal Negron, the Fort Buchanan energy manager on this project."
This first turbine on Fort Buchanan is at the South Gate. Turbines will also be erected at the old Directorate of Public Works on Fort Buchanan, and at the Roosevelt Roads location. The anticipated completion date is June 2013.
There are 10 energy conservation measures in the works that include the wind turbines, solar PV, and water conservation measures. Fort Buchanan is a NetZero installation for water conservation. Work includes air cooled chiller replacement; energy management controls system installation; heating, ventilation and air conditioning system upgrades and window/split air conditioning system retrofits; energy-efficient interior and exterior lighting including street lighting upgraded to LED; occupancy sensors; renewable energy including a 1.2 megawatt solar photovoltaic, solar thermal water heating, and 825 kilowatt wind power generation; water/sewer conservation and irrigation system; and retro-commissioning services.
