Joint Region Marianas Energy Analysis: Military Consumption, Conservation & Renewable Energy on Guam

The Department of the Navy (DON) has taken great strides to decrease its facilities’ energy consumption in order to meet Federal and Department of Defense (DOD) energy conservation initiatives. In response to the Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007 the U.S. Navy has made it a priority to decrease its consumption of oil and fossil-fuel generated energy. Among other initiatives, the Navy is currently working towards a goal to reduce shore-based energy consumption by 50 percent, to generate half of shore-based energy requirements by alternative sources, and to achieve net zero status for half of all its installations by 2020. These strategic goals, ultimately, enable the Navy, Department of Defense, and the U.S. to move towards energy independence and to operate in a more sustainable manner. In an effort to meet DON Goals, the Joint Region Marianas (JRM) has implemented an energy conservation program that has included an energy awareness campaign, energy conservation retrofits on less efficient facilities, and the introduction of minor amounts of renewable energy applications. Despite these efforts, however, the region has seen only modest improvements in energy use intensity. Additionally, region-wide gross floor area has increased by almost 15 percent from FY03 and the region-wide energy consumption has increased by approximately eight percent within the same time period. This report provides a high-level analysis of JRM energy consumption over a 1 U.S. Department of the Navy, “A Navy Energy Vision for the 21st Century,” 6-10. ten year period, a detailed analysis of consumption trends by facility type, and identifies specific buildings that currently consume excess energy; resulting in a potential energy savings to the region of approximately 85 million KWh. Additionally, this report analyzes potential partnership opportunities with Guam Power Authority (GPA) as well as other strategies to increase the generation of renewables both on-base and off-base in order to meet DON strategic energy reduction goals. The analysis is broken down into four primary sections: current energy consumption patterns, detailed facility type analysis, energy conservation and savings potential, and renewable strategies
