Stirling Solar Array - Tooele Army Depot

Tooele, UT United States

The solar arrays will be exposed to harsh weather conditions throughout the year. Hot-dip galvanizing was chosen for this project due to its longevity and durability. There are many exposed steel components on the solar array supports and HDG provides protection for the edges and corners as well as the inside of the tubular sections. The dishes are guaranteed to last at least 25 years and by utilizing galvanizing for corrosion protection, the dish supports will be maintenance free for decades exceeding the project’s life expectancy.

On August 18, 2013, General Martin E. Dempsey, Chairman of the Joint Chiefs of Staff, and Katherine Hammack, Assistant Secretary of the Army for Installations, Energy and Environment, attended the ground breaking ceremony of the $9.6 million solar power renewable energy project at the Tooele Army Depot. The Army Depot provides storage, inspection, maintenance and testing of training stocks as well as war reserve ammunition. The depot also designs, develops, manufactures and fields specialized equipment used in the maintenance and demilitarization of munitions all over the world.

The Department of Defense has made a commitment to clean energy by setting a goal of three gigawatts of renewable energy on Army, Navy, and Air Force installations by 2025. The Army’s goal is to produce one gigawatt of electricity which is one third of the Defense Department’s goal. The Tooele Depot is one of 16 Army commands in the country working to achieve “net zero” status by producing at least as much energy as they consume. This goal is not only to be better stewards of the nation’s resources, but also a cost savings as well as reduce the installation's vulnerability to domestic terrorism.

This 1.5 megawatt solar array system is one of the military’s first utility-sized renewable energy projects. It is expected to generate 30% of the Army Depot’s energy which is equivalent to supplying power to 300–400 homes. This will reduce the Depot’s energy consumption from the local utility at a cost savings of an estimated $260,000 annually. The system includes 430 state of the art dish collectors with parabolic mirrors that spread across 17acres powered by a Stirling generator which converts the sun’s heat into electrical energy. They have two drives that move the dishes vertically and rotationally and are linked to the location by GPS enabling them to track the sun at all times.

The Department of Defense made a historical commitment to clean energy by setting the goal for military installations to develop renewable energy projects to produce 3 gigawatts of energy by 2025. This new direction throughout all three branches of the military may open the market to more similar projects like the one at the Tooele Army Depot. The aesthetic durability of hot-dip galvanizing is not only economical but environmentally friendly making it the most green alternative corrosion protection. The decades of maintenance free coating protection of HDG reduces the carbon footprint caused by paint maintenance. Utilizing hot-dip galvanizing is the most viable option to protect the assets of these renewable energy projects for many years into the future.
