Dispatchability Versus Intermittency

Intermittent resources produce on nature's schedule; dispatchable resources produce on the operator's. A grid needs enough of the latter.

Two ends of a spectrum

Intermittent generation, wind and solar, produces when the resource is available. Dispatchable generation produces when instructed, up to its rating. Most grids blend both: cheap intermittent energy plus enough dispatchable capacity to keep supply matched to demand every second. The mix determines reliability.

The burner (MetroVolt) is designed as a dispatchable resource. Its fuel is stored, its confinement is steady-state, and its direct-conversion output can, in principle, be trimmed on command. That places it firmly on the dispatchable end, alongside gas and nuclear but without their water footprint or carbon.

Why the balance matters

As intermittent share rises, each remaining dispatchable megawatt becomes more valuable because it must cover a larger and more variable residual. Under-provisioning dispatchable capacity risks shortfalls; over-provisioning wastes capital. A water-light, sitable dispatchable resource widens where that capacity can be placed.

Honest gate

Dispatchability here is a design property. The achievable dispatch band and ramp are unproven because the plug regime is far beyond any operated device, and single-unit availability (0.86 to 0.995) trails Tier III (0.99982). MetroVolt is a candidate dispatchable resource pending its 2032 test.
