Question

What will fusion electricity cost?

Kronos publishes a full LCOE ladder — FOAK $84–92/MWh falling to $48–56/MWh at fleet scale — and explicitly declines to claim the sub-$40 numbers others quote.

Kronos treats cost the way it treats physics: as a ladder with stated assumptions, not a headline. The levelized cost of electricity (LCOE) ladder runs from a first-of-a-kind $84–92/MWh, down through a nth-of-a-kind $48–84/MWh, to a fleet-scale $48–56/MWh. The required PPA band is $56–92/MWh, and the physical floor is roughly $18–30/MWh.

Just as important is what Kronos will not claim. The sub-$40/MWh numbers that circulate in fusion marketing are treated as unreachable for this architecture, and excluded. Being low-neutron helps the economics structurally — a smaller shield, less material damage, and higher availability than a D–T plant — but the company's discipline is to publish the ladder, the assumptions, and the floor together.

Questions & answers

What is the projected cost of fusion electricity?
Kronos publishes a levelized-cost ladder rather than a single number: first-of-a-kind (FOAK) $84–92/MWh, falling to $48–84/MWh at nth-of-a-kind (NOAK) and $48–56/MWh at fleet scale. The required power-purchase-agreement (PPA) price sits at $56–92/MWh, and the physical cost floor is about $18–30/MWh.
Do you claim the very low $25–40/MWh figures some quote?
No. Kronos explicitly does not claim the $25–40/MWh band — the internal analysis treats it as unreachable for this architecture, and says so. The honest comparison is against the NOAK $48–84/MWh band.
Why does cost fall over time?
The decline follows Wright's law — cost falls with cumulative units built — plus the structural advantage of avoiding the 33–42% availability/LCOE penalty that neutron-heavy D–T concepts carry.
