Survival rules in the energy storage battlefield

Should batteries and tactical energy storage be included in pre-positioned war reserve materiel?

Batteries and tactical energy storage should be included in pre-positioned war reserve materiel to ensure today’s modernized joint force is electronically equipped for success, Defense Logistics Agency Land and Maritime officials say in a white paper published last month (DLA common access card required to view).

Can long-duration energy storage (LDEs) meet the DoD's 14-day requirement?

This report provides a quantitative techno-economic analysis of a long-duration energy storage (LDES) technology, when coupled to on-base solar photovoltaics (PV), to meet the U.S. Department of Defense’s (DoD’s) 14-day requirement to sustain critical electric loads during a power outage and significantly reduce an installation’s carbon footprint.

Can a non-LDEs solution provide 100% survival probability over a 14-day outage?

Given that currently non-LDES solutions do not provide military installations a 100% survival probability over a 14-day outage (14) (6), requiring an LDES-based solution to achieve 100% is unrealistic. There is a trade-off between survival probability and costs (i.e., NPV).

Is there a trade-off between NPV and survival probability?

There is a trade-off between survival probability and costs (i.e., NPV). Higher survival probability, closer to 100%, can always be achieved by increasing the sizes of the DERs but often at a significant cost. Our approach was to use the modified version of REopt in an iterative fashion.
