Baseload Versus Firm Capacity

Baseload describes how a plant is run; firm capacity describes what a grid can count on. The burner is designed for both roles.

Two words that are often confused

Baseload traditionally means a plant run flat-out around the clock because it is cheap to run and slow to change. Firm capacity is the reliability attribute described elsewhere in this category. Historically the two overlapped, since coal and fission plants were both baseload and firm. On a high-renewables grid they separate: the valuable trait is not running flat all the time but being available and adjustable when needed.

The burner (MetroVolt) can serve as a baseload machine, sitting at high output continuously to anchor a data-center campus or a city district. But its design intent is broader: to move within its operating band so it can also firm a renewable-heavy grid rather than only fill the bottom of the load curve.

Steady-state is a physics choice

A tandem mirror is an inherently steady-state confinement scheme: unlike a pulsed tokamak, it is designed to hold a continuous burn. That makes continuous baseload operation natural and avoids the duty-cycle penalties of pulsed machines. Direct energy conversion likewise runs continuously rather than in thermal cycles.

Design-stage caveat

Continuous operation is a design property being studied in simulation, not a demonstrated one. The open plug-confinement and regime gates (the plug operates 166 to 830 times beyond any existing device) mean sustained steady-state burn has not been post-dicted from experiment. Treat baseload capability as a target of the 2032 test unit, not a present fact.
