Recycled Power Plant Equipment Bolsters America’s Premier Space Launch Services Provider—United Launch Alliance—in its Energy Efficiency, Saves on Energy Spend

DECATUR, Ala. – Nov. 11, 2015 – Thanks to motor-speed regulating machines sourced from another
company’s facility, Alabama-Decatur Energy announced a recent energy efficiency upgrade at its plant that
supplies thermal utilities to customer United Launch Alliance (ULA). This upgrade will significantly drive
down ULA’s energy use at their Decatur rocket factory.

Alabama-Decatur Energy, which is a part of GDF SUEZ Energy North America, supplies utilities to space
launch services provider ULA via steam, chilled water and compressed air to heat and cool the complex,
regulate rocket manufacturing chemical processes and operate pneumatic tools. In collaboration with ULA,
Alabama-Decatur installed two ABB 1,500-horsepower variable frequency drives to regulate the speed of
the motors on two of the plant’s 1,425-ton chillers. Prior to installation of the variable frequency drives, the
chillers’ motors ran on full power 24 hours a day to power ULA’s 1.6 million-square-foot facility that
manufacturers Atlas V and Delta IV launch vehicles.

When Alabama-Decatur Energy Plant Manager Kevin Miller learned from a colleague that the equipment
was available for reuse from another plant in the fleet that had been decommissioned, he realized the
machines could reduce the operating costs at ULA.

“The collaboration between ULA and Alabama-Decatur Energy is a testament to ULA’s commitment to
innovation through increased focus on sustainability and energy efficiency. The team at Alabama-Decatur
Energy worked to decrease our energy consumption in our Decatur factory,” said Craig Langford, director
and general manager of program operations.

With an eye toward conserving energy and cost reduction, Alabama-Decatur Energy and ULA’s power and
facilities professionals teamed up to examine, craft and implement the upgrade.

“I knew this would help us be more competitive in helping ULA become more energy efficient as well as
drive ULA’s energy costs down,” Miller pointed out. “I see this project as part of our long-term customer
focus. We think of it as an industrial-scale example of Reduce, Reuse and Recycle.”
