    (a) Program Authorized.--The Secretary of a military department may 
carry out a pilot program under which the Secretary will enter into 
energy savings performance contracts under the authority of section 801 
of the National Energy Conservation Policy Act (42 U.S.C. 8287) for the 
purpose of achieving direct energy savings and secondary savings in 
mobile assets of the Armed Forces under the jurisdiction of the 
Secretary and other nonbuilding applications of the military 
department.
    (b) Implementation Report.--Not later than two years after entering 
into the first energy savings performance contract under the pilot 
program, the Secretary of the military department concerned shall 
submit to Congress a report describing the implementation of the pilot 
program, including the number of energy savings performance contracts 
executed, the types of mobile assets and other nonbuilding applications 
covered, and the direct energy savings and secondary savings achieved.
    (c) Definitions.--In this section:
            (1) Mobile asset and nonbuilding application.--The terms 
        ``mobile asset'' and ``nonbuilding application'' mean--
                    (A) any class of vehicles, devices, or equipment 
                that--
                            (i) is transportable under the power of the 
                        applicable vehicle, device, or equipment by 
                        land, sea, or air; and
                            (ii) consumes energy from any fuel source 
                        for the purpose of--
                                    (I) that transportation; or
                                    (II) maintaining a controlled 
                                environment within the vehicle, device,

            (2) Secondary savings.--The term ``secondary savings'' 
        means additional energy or cost savings that are a direct 
        consequence of the energy savings that result from the energy 
        efficiency improvements that were financed and implemented 
        pursuant to an energy savings performance contract. The term 
        includes--
                    (A) energy and cost savings that result from a 
                reduction in the need for fuel delivery and logistical

        preparedness and resilience initiatives? If so, what are these 
        obstacles and do they require congressional action to increase 
        security on installations?
            (5) What opportunities exist for effective public private 
        partnerships or contracts with industry to address and mitigate 
        the effects of these conditions?
Department of Defense Energy Security Act of 2015 This bill authorizes military departments to carry out pilot programs to enter into energy savings performance contracts through FY2041, for the purpose of achieving direct energy savings and secondary savings in: (1) certain mobile assets of the Armed Forces that consume energy for the purpose of transportation or maintaining a controlled environment within the vehicle, device, or equipment; and (2) any federally owned equipment used to generate electricity or transport water. Under an energy savings performance contract, a private party agrees to fund energy-efficient upgrades in the federal government and the federal agency agrees to pay the private party from reductions in the agency's energy costs. The U.S. Army must report on research since October 1, 2010, on energy efficiency of tactical vehicles. The Department of Defense (DOD) may carry out research to improve military vehicle technology to increase combat vehicle fuel economy or reduce fuel consumption. DOD shall establish an online, centralized repository for all DOD operational energy-related research and development efforts. The bill establishes a Department of Defense Alternative Fuel Vehicle Infrastructure Fund for installing and operating alternative fuel dispensing stations for DOD's alternative fueled vehicles and other related infrastructure. DOD must establish a program to develop and support projects designed to foster secure and reliable sources of energy for military installations, including incorporation of advanced energy metering, resilient energy, energy storage, and redundant power systems. DOD must report on: (1) the costs and benefits associated with requiring 25% of National Guard and Reserve facilities to have at least a 21-day on-site power storage capacity to assist civil authorities in case of man-made or natural disasters; (2) energy efficiency language in the most recent aerial refueling tanker contract and the Logistics Civil Augmentation Program contract; and (3) DOD's strategy and initiatives to mitigate the impact of expected increased water shortages, instances of wildfire, increased drought, flooding due to sea level rise, and coastal erosion from storm surges to ensure optimal military readiness.
