Continuity of Operations

Continuity of operations is the discipline of keeping mission-critical loads powered through faults, outages, and long grid absences.

COOP as a power problem

Continuity of operations (COOP) treats power as something the mission cannot lose, not as a utility bill. The measure of success is simple: critical loads stay energised across a defined set of disruptions, from a momentary sag to a multi-week loss of the outside grid. Aegis is positioned as the source that carries the long tail of that requirement, where diesel reserves would otherwise run out.

Layers of assurance

COOP is built in layers so that no single failure reaches the critical load. The outside utility, when present, is the first layer. Aegis in a redundant set is the firm on-site layer. A storage buffer bridges the seconds around transitions and the minutes around a unit trip. The innermost layer is aggressive load management that sheds non-critical demand to protect the mission core.

• Utility feed — used when available, never depended on
• Aegis N+1 — firm on-site generation, years of fuel
• Storage — sub-minute bridging and transition ride-through
• Load shedding — protect critical load by dropping the rest

Where the fuel independence pays off

The distinguishing COOP property is duration. Fuelled generation is limited by what is in the tanks and what a convoy can replenish under contested conditions. Aegis carries years of energy as on-site fuel inventory, so the continuity window is set by maintenance and availability rather than by resupply.

This is bounded by the availability gate: a design-stage estimate of 0.86–0.995 means unplanned outages are expected, so COOP for Aegis is explicitly a redundancy-and-storage architecture, not a single-unit promise.
