Question
How much does a fusion plant cost?
Kronos publishes a levelized-cost ladder — FOAK $84–92/MWh falling to $48–56/MWh at fleet scale — rather than a single capital number, and declines the sub-$40 figures others quote.
Kronos treats cost the way it treats physics — as a transparent range with stated assumptions. The full picture is on what will fusion electricity cost? and the LCOE and Wright's law pages.
Questions & answers
What will fusion electricity cost?
Kronos publishes a levelized cost of electricity (LCOE) ladder: first-of-a-kind $84–92/MWh, falling to $48–84/MWh at nth-of-a-kind and $48–56/MWh at fleet scale, with a required PPA of $56–92/MWh and a physical floor around $18–30/MWh.
Do you claim the very low numbers other companies quote?
No. Kronos explicitly declines the sub-$40/MWh figures common in fusion marketing, treating them as unreachable for this architecture. The honest comparison is against the NOAK $48–84/MWh band.
Why publish a ladder instead of one number?
Because a first unit and a fleet unit cost very different amounts, and being transparent about that — with stated assumptions — is more credible than a single optimistic headline. Cost falls with cumulative production via Wright's law, helped structurally by the low-neutron availability advantage.
