Levelized Cost of Electricity (LCOE)

LCOE is the lifetime cost per unit of electricity generated. Kronos publishes a full LCOE ladder rather than a single headline number.

What

Lifetime cost ÷ lifetime electricity, in $/MWh

Kronos ladder

FOAK $84–92 → NOAK $48–84 → fleet $48–56

Required PPA

$56–92/MWh

Not claimed

the sub-$40/MWh band (unreachable here)

Levelized cost of electricity (LCOE) expresses a power plant's total lifetime cost — capital, fuel, operations, financing — divided by all the electricity it generates, in dollars per megawatt-hour. It is the standard way to compare generating technologies on a like-for-like basis.

Kronos publishes a ladder, not a headline: a first-of-a-kind LCOE of $84–92/MWh, falling to $48–84/MWh at nth-of-a-kind and $48–56/MWh at fleet scale, with a required power-purchase price of $56–92/MWh and a physical floor near $18–30/MWh. Equally important is what Kronos declines to claim — the sub-$40/MWh figures common in fusion marketing are treated as unreachable for this architecture. The cost decline follows Wright's law, helped structurally by the low-neutron availability advantage.
