Load-Following & Firm Power

Aegis is designed as a firm baseload source; storage and load management handle fast swings the plasma cannot follow.

Firm, not fast

Aegis is a firm source: it aims to hold a steady output around the clock, independent of weather or time of day. It is not a fast-ramping peaker. A fusion plasma changes operating point on the timescale of its control systems, not in milliseconds, so the installation pairs firm generation with faster resources to follow load.

Division of labour

Firm baseload comes from Aegis. Fast transients — a large load switching on, the islanding swap — are absorbed by storage. Sustained demand changes are met by dispatching more or fewer units and by managing deferrable load. This layered approach gives the installation both stability and responsiveness without asking the plasma to do something it cannot.

• Aegis: firm, steady baseload
• Storage: sub-second to minutes transient response
• Unit dispatch: coarse steps for sustained changes
• Load management: shape demand to available generation

Weather independence

Unlike wind or solar, Aegis output does not depend on weather, season, or daylight. That is the core of ‘firm’: the source is available on demand, limited only by maintenance and the availability gate, which is why redundancy matters and why storage covers the fast edges.

These are design-stage operating characteristics of the burner: it is characterised as a weather-independent firm source whose limits are maintenance and the availability gate, with fast behaviour delegated to storage and dispatch rather than to the plasma. This is why Aegis is described as a firm anchor rather than a dispatchable peaker: it is best used to carry the steady mission base, with storage and dispatch handling the edges, and it is honest about not being a fast-cycling machine.
