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.
