0.61 to 0.84 Gigawatts: What One MetroVolt Delivers

City-scale firm power from a machine that fits behind existing fences.

On its conservative ledger a MetroVolt unit exports 0.61 GW of electricity — round-the-clock, fuel-secure, carbon-free. With the gated channeling credit the same machine books 0.84 GW. That is roughly a half-million-plus American homes from one compact plant.

The science

The plant ledger is computed line by line at the frozen point (Table 22, deposited): 2,409 MW fusion; charged-particle and radiation streams harvested by the multi-modal direct-energy-conversion train; bottoming cycle on the balance; 1.18 GW gross; 0.61 GW net after all plant loads, at engineering gain Q_eng 2.1. The channeled posture lifts gross to 1.34 GW and net to 0.84 GW (Q_eng 2.7).

Both postures obey the same discipline as the physics: no efficiency is booked beyond its cited heritage, and the sustainment power that runs the plasma is charged fully against output.

Why it matters

0.61 GWe firm is a fleet-planning number: it replaces a retiring coal or gas unit on a similar grid interconnect, without the fuel logistics and without the emissions. The upside case is the same interconnect earning 38% more — a growth option embedded in every unit sold.

Straight answersThese are simulation-derived values at the frozen point, contingent on the confinement gate; the near-thermal fallback (0.4–0.5 GWe) is published with equal prominence in the series.
