Department of Defense Energy Security Act of 2015

Summary: Department of Defense Energy Security Act of 2015   This bill authorizes the Department of Defense (DOD) to 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;  conduct a program to develop and support projects designed to foster secure and reliable energy sources for military installations, including incorporation of advanced energy metering, renewable energy, energy storage, and redundant power systems; and  develop associated cost and benefit metrics.  The DOD Alternative Fuel Vehicle Infrastructure Fund is established in the Treasury to support installing and operating alternative fuel dispensing stations for DOD's alternative fueled vehicles and other related infrastructure.   DOD shall:   report on 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; and  submit a plan for integrating energy storage, micro-grid technologies, and on-site power generation systems at military installations at risk of power interruptions due to geographic location, dependence on connections to the electric grid, or other factors. 

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Department of Defense Energy 
Security Act of 2015''.

SEC. 2. AUTHORIZATION FOR RESEARCH TO IMPROVE MILITARY VEHICLE 
              TECHNOLOGY TO INCREASE FUEL ECONOMY OR REDUCE FUEL 
              CONSUMPTION OF MILITARY VEHICLES USED IN COMBAT.

    (a) Research Authorized.--The Secretary of Defense, acting through 
the Assistant Secretary of Defense for Research and Engineering and in 
collaboration with the Secretary of the Army and the Secretary of the 
Navy, may carry out research to improve military vehicle technology to 
increase fuel economy or reduce fuel consumption of military vehicles 
used in combat.
    (b) Previous Successes.--The Secretary of Defense shall ensure that 
research carried out under subsection (a) takes into account the 
successes of, and lessons learned during, the development of the Fuel 
Efficient Ground Vehicle Alpha and Bravo programs to identify, assess, 
develop, demonstrate, and prototype technologies that support 
increasing fuel economy and decreasing fuel consumption of light 
tactical vehicles, while balancing survivability.

SEC. 3. REQUIREMENT TO ESTABLISH REPOSITORY FOR OPERATIONAL ENERGY-
              RELATED RESEARCH AND DEVELOPMENT EFFORTS OF DEPARTMENT OF 
              DEFENSE.

    (a) Repository Required.--Not later than December 31, 2016, the 
Secretary of Defense, acting through the Assistant Secretary of Defense 
for Research and Engineering and in collaboration with the Assistant 
Secretary of Defense for Operational Energy Plans and Programs and the 
Secretaries of the military departments, shall establish a centralized 
repository for all operational energy-related research and development 
efforts of the Department of Defense, including with respect to the 
inception, operational, and complete phases of such efforts.
    (b) Internet Access.--The Secretary of Defense shall ensure that 
the repository required by subsection (a) is accessible through an 
Internet website of the Department of Defense and by all employees of 
the Department and members of the Armed Forces whom the Secretary 
determines appropriate, including all program managers involved in such 
research and development efforts, to enable improved collaboration 
between military departments on research and development efforts 
described in subsection (a), enable sharing of best practices and 
lessons learned relating to such efforts, and reduce redundancy in such 
efforts.

SEC. 4. SECURE ENERGY INNOVATION PROGRAM.

    (a) In General.--The Secretary of Defense shall conduct 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, renewable energy, energy storage, and 
redundant power systems.
    (b) Metrics.--The Secretary of Defense shall develop metrics for 
assessing the costs and benefits associated with secure energy projects 
proposed or implemented as part of the program conducted under 
subsection (a). The metrics shall take into account financial and 
operational costs associated with sustained losses of power resulting 
from natural disasters or attacks that damage electrical grids serving 
military installations.

SEC. 5. AUTHORITY TO USE ENERGY SAVINGS INVESTMENT FUND FOR ENERGY 
              MANAGEMENT INITIATIVES.

    Section 2919(b)(2) of title 10, United States Code, is amended by 
striking ``, to the extent provided for in an appropriations Act,''.

SEC. 6. ESTABLISHMENT OF DEPARTMENT OF DEFENSE ALTERNATIVE FUELED 
              VEHICLE INFRASTRUCTURE FUND.

    (a) Establishment of Fund.--There is established in the Treasury a 
fund to be known as the ``Department of Defense Alternative Fuel 
Vehicle Infrastructure Fund''.
