Capacity Factor And Availability

Capacity factor is how much energy a plant actually delivers; availability is how often it can. For firm service, availability is the harder target.

Two different fractions

Capacity factor is annual energy delivered divided by energy at full nameplate. Availability is the fraction of time the plant is able to run when called, whether or not it is dispatched. A peaker can have low capacity factor but high availability. For a firm baseload burner the two are close, because the design intent is to run near full output whenever it is available.

The burner (MetroVolt) targets high capacity factor by running steady-state. The limiting term is availability: forced outages, planned maintenance, and any trip of the plasma or the direct-conversion train subtract from it.

The availability gap

This is the load-bearing grid gate. The design-stage availability estimate is 0.86 to 0.995. A hyperscale Tier III data center expects 0.99982. That is 30 to 100 times more downtime than the most demanding load will tolerate from a single source. It does not sink the case, but it defines it: MetroVolt is not, today, a sole Tier III source, and the design must lean on redundancy, fleet operation, and a grid tie.

Closing this gap is an explicit objective of the test program. Until measured on hardware, treat the numbers above as targets from simulation and reliability modeling.
