註釋Military bases require large volumes of electricity to execute their critical missions, but their reliance on the commercial grid and a decades-old backup power paradigm can put their critical missions at risk. Already, DoD experiences multi-day power outages and pays a high cost for these outages in dollars and mission risk. The triggers for outages severe-weather, physical terrorism, and cyber-attacks -- are only expected to increase in the near future. Against that backdrop, some bases are moving towards more advanced energy security solutions. Instead of solely relying on the existing paradigm of having one standalone generator tied to each building with a critical load, they are putting in place the building blocks of smart microgrids. They are making that move because they are able to achieve "triple play" benefits -- more energy security and independence from the commercial grid, lower power costs, and an enhanced ability to integrate renewable energy. This reflects a real change in DoD's approach to energy security. That change is enabled by improvements in technology cost and performance. This alternative to longstanding energy practice is finally viable, at DoD and in other commercial settings. While renewable energy can certainly enhance energy security, the current cost of energy storage (e.g., large-scale batteries) means that intermittent sources of renewable energy (wind and solar) cannot yet cost effectively provide the primary source of energy security for critical loads. Our analysis demonstrates that microgrids provide more energy security for less money than the Services are currently paying for standalone generators. The Services do not need to pay a premium for energy security. From a business perspective, DoD is currently underinsuring many non-critical loads on its military bases, including its R & D laboratories, industrial facilities, and many other important functions, and paying more for critical load insurance than need be
