DoN: Three Pillars of Energy Security
Reliability
The percentage of time energy
delivery systems (utilities) can
serve customers at acceptable
regulatory standards.
Resiliency
The ability of a system to anticipate,
resist, absorb, respond, adapt,
and recover from a
disturbance.
Efficiency
The use of the minimal energy
required to achieve the
desired level of service.
Energy Security

Holistic Energy Security Approach
Islanding microgrid capabilities
Potential community microgriding capabilities
Critical assets powered by dedicated base energy sources
ESPCs / UESCs make buildings and utilities more efficient producing long-term cost savings
Long-term PPAs can provide cost stability for the DON and help to incentivize the diversification of regional energy sources

Power Matters for the Warfighter
8
The Department of Defense “should explore alternate and renewable
energy sources that are reliable, cost effective, and can relieve the
dependence of deployed forces on vulnerable fuel supply chains. …The purpose of such efforts should be to increase the readiness and reach of
our forces.”

Marine Corps Air Station (MCAS) Yuma Microgrid
In December 2016, The Department of the Navy, U.S. Marine Corps and Arizona Public Service (APS) announced the completion of a 25-megawatt microgrid built on MCAS Yuma.

• The microgrid makes MCAS Yuma 100 percent resilient to external grid failures
• It also provides enough backup power to cover the entire base's current and projected energy requirements, ensuring no disruptions to the base's mission.

Marine Corps Air Station (MCAS) Yuma Microgrid
This created a smooth transition from grid power to
the base's own microgrid power, and prevented MCAS Yuma from experiencing any losses in their mission during
an outage.
MCAS Yuma was able to avoid the extensive time and effort associated with mandatory
maintenance checks of mechanical and electrical
systems (e.g. boilers, pumps, fire alarms, and cooling
towers) after a power outage.
In March 2017, a fault on the commercial electric grid caused areas of Yuma to lose power. • The microgrid automatically detected this fault, started up, and fed
enough power to meet the base's load while correcting the frequency to the grid.

An approximately 7 MW solar system and 6 MW, 18 MWh battery system on the local grid • Cutting edge battery system
– Extremely high energy density– Long life-span– 100% recyclability– Long and short term generation asset
NB Ventura County: Solar and Battery Storage
• The project will provide both the DON and Ventura County community with energy resiliency and storage reliability
• The system can cover over 65% of the base’s peak loads for hours at a time

Ongoing Efficiency Projects (ESPCs)
Naval Amphibious Base (NAB) Coronado:• Began as a MCON project: ~$91M• Capital Investment: $70M• Annual Estimated Cost Savings: $5M • Total Energy Savings: 321,115 (MMBTU/yr)
Naval Station Guantanamo Bay:• Fence-to-fence analysis of needs• Maximizing cost savings• Reducing petroleum reliance via smart
grid, distributed energy (batteries, PV, combined heat and power plant, HVAC upgrades)
Marine Corps Recruiting Depot Parris Island:• Capital Investment: $91M• Annual Estimated Cost Savings: $6.9M • Total Energy Savings: 384,962 (MMBTU/yr)• Total Water Savings: 74,597 (kGal/yr)• It will install a cogeneration (power & steam) plant,
photoelectric power generation, and power storage. It will also replace lighting and plumbing fixtures, boilers, chillers, HVAC systems, and control systems.
