Interdependent critical infrastructure and generation assets tend to cluster around communities (i.e., load centers) and can be combined into an Secure Power Enclave as shown in the graphic above.
Secure Power Enclaves can support facilities on either the transmission or distribution grid including at transmission voltages. Microgrids, by contrast, are typically connected through Points of Common Coupling only to the distribution network at lower voltages. Microgrids within a community, however, can be embedded within a Secure Power Enclave.
Secure Power Enclaves provide several unique security advantages:
The potential for a layered defense goes even deeper than the regional grid and a Secure Power Enclave. It could also include microgrids within the Secure Power Enclave as well as hardening of facilities, especially critical infrastructure, served by the Secure Power Enclave, as illustrated below. Community microgrids, in particular, could be useful to this layered defense.
