What is firm power?

Firm power is electricity you can rely on at any hour, regardless of the weather. Because the Kronos machines run continuously, they deliver it as a built-in feature — not a statistical average.

Firm power
Available on demand, any hour
Vs intermittent
Not weather-dependent like wind/solar
Kronos machines
Steady-state — firm by construction
Who needs it
Data centers, cities, defense installations

Firm power is capacity you can dispatch whenever it is needed — day or night, calm or windy. It is the opposite of intermittent generation, whose output follows the weather. Grids and large continuous loads need a firm foundation underneath the variable sources.

Because the Kronos machines run steady-state rather than intermittently, they supply firm, dispatchable power as a structural property. That is why the burner targets loads that must be served around the clock — data centers, cities, and defense installations — and why a large synchronous fusion plant also provides grid inertia that inverter-based renewables do not.
