Aging energy infrastructure has made it increasingly difficult for naval installations to be adequately prepared to meet their missions. In March 2020, the U.S. Navy set an accelerated course for resilience by implementing a new energy strategy, the Installation Energy Resilience Strategy (IERS), which is focused on the delivery of uninterrupted, reliable, and high-quality power necessary to meet the evolving mission requirements outlined in the National Defense Strategy.Within IERS, the Navy stated the need to optimize the use of every available authority to accelerate thedelivery of secure and reliable energy- and importantly, have assured energy whenever or wherever it is required. The new strategy also adopted a resilience policy set to enable key military bases to go off-grid for at least two weeks by late 2025. This effort ensures installations are independent of public utilities.
