Keesler Energy Manager Billy Stevenson and Reggie Lechner, Keesler energy management control systems operator, analyze base power consumption in 2014. Following the award of an Energy Savings Performance contract in 2019, the Mississippi base has now implemented four energy conservation measures. Thanks to the conservation upgrades, the base expects an annual savings of 113,840 million British Thermal Units, a 15.8 percent reduction in energy consumption and $3.4 million in water savings.
