    Utah Army Depot Follows Path to ‘Net Zero’0

    Two renewable energy projects expected to go online by the end of next year will help Tooele Army Depot near Salt Lake City become a “net zero” energy installation by 2020. The Army Corps of Engineers recently installed the depot’s second wind turbine, which will generate almost 2 megawatts of power when the $6.5 million project is complete later this year. The two turbines will generate nearly 60 percent of the depot’s energy needs, reported USACE Public Affairs. The first turbine has a 1.5-megawatt capacity. Nearby, a 1.5-megawatt solar array, consisting of 429 Stirling engine solar dishes spread across 15 acres, is scheduled to be fully operational in 2017. The $10.7 million array will provide about 25 percent of the installation’s electricity. Other planned renewable sources, including battery storage systems, a microgrid and backup generators, will enable Tooele to operate independently of the grid by 2020. Those efforts will cost $5.1 million and produce 1.2 megawatts of power. The Corps’ work at Tooele is part of the Army’s Energy Conservation Investment Program, which is designed to increase renewable energy consumption on installations.

    Air Force to Test Performance of Microgrid at JB Pearl Harbor-Hickam0

    The Air Force Research Laboratory is conducting a microgrid demonstration project at Joint Base Pearl Harbor-Hickam in Hawaii to test whether the 154th Wing of the Hawaii Air National Guard can function independently of the power grid for extended periods of time. AFRL will incorporate a number of energy-harvesting and storage technologies under the five-year, $20 million cooperative agreement, including hydrogen vehicles and equipment, waste energy usage, wind power harvesting and solar panels, reported the AFRL Materials and Manufacturing Directorate. The effort builds upon a previous cooperative agreement that established advanced hydrogen production and hydrogen-powered vehicles and equipment at the base …

  • Air Force’s Vehicle-to-Grid Technology Passes Milestone0

    The Air Force earlier this month completed its final vehicle-to-grid (V2G) certification testing for a fleet of plug-in electric vehicles at Los Angeles Air Force Base, proving the vehicles could both receive and supply power to the electrical grid and operate without interfering with the installation’s mission. The fleet has the capability to direct power to and from the electrical grid when the vehicles are not being driven. Bidirectional charging stations at the base can charge a vehicle from the local utility grid as well as discharge a vehicle’s onboard battery to support its V2G capability …

  • Utility’s Guilty Plea to Environmental Violations Could Jeopardize Power Supply to N.C. Bases0

    Duke Energy, the only major electricity supplier in North Carolina, is negotiating with the Environmental Protection Agency for a waiver from a federal statute barring defendants that commit criminal violations from engaging in business with federal entities. If an agreement can’t be worked out, the nation’s largest electric utility would be barred from serving military installations and other federal facilities in North Carolina, Duke said in federal court on Tuesday …
