Secure Power Enclave Definition: A local section of an electric T&D network containing both power generation and critical infrastructure facilities that can, when necessary, be islanded to operate independently of the rest of the T&D network.
Secure Power Enclaves provide:
Although both have the capability to electrically island, Secure Power Enclaves are not microgrids. Unlike microgrids, Secure Power Enclaves are an intrinsic part of the regional electric transmission and distribution grid and have no Point of Common Coupling with the grid. Secure Power Enclaves provide electricity resilience to more facilities than microgrids and can better serve critical infrastructure further apart and under different ownership. Secure Power Enclaves can also be used in coordination with microgrids to provide a layered defense against threats.
The December 2018 National Infrastructure Advisory Committee (NIAC) report
“Surviving a Catastrophic Power Outage” recommended enclaves as a way to ensure
that communities have the ability to continue providing critical services during long-term power outages. Other studies have also shown the need for enclaves. Secure Power Enclaves using technology developed by OnGrid Options, LLC is the only method now available to implement enclaves.
