Prior state
Experimental fusion devices had demonstrated net energy gain in short pulses; no commercial plant had operated continuously for multi-year periods under utility dispatch rules.
Material change
A small number of first-of-a-kind commercial fusion plants achieve continuous or high-capacity-factor operation for periods exceeding three years and are integrated into regional electricity markets as firm capacity.
Why now
Late-decade timing aligns with the completion of construction pipelines begun in the late 2030s and early 2040s and with regulatory licensing cycles that mature only after operational data accumulate.
Mechanism and resistance
Technical learning and high electricity prices in constrained grids drive deployment; resistance arises from residual capital-cost overruns, supply-chain bottlenecks for specialized materials, and incumbent generation interests.
Consequences
The plants supply measurable firm low-carbon power to their host grids; the demonstration effect accelerates follow-on investment but does not yet displace the bulk of fossil or fission capacity.
End state
At least two commercial fusion facilities in high-income jurisdictions have completed multi-year continuous operation under utility dispatch and regulatory oversight.
Observable test
Grid-operator generation reports and independent technical audits record continuous or high-capacity-factor operation of named commercial fusion units for periods longer than three years.
Disconfirming sign
Pilot plants remain intermittent, fail to meet capacity-factor targets, or are mothballed after short demonstration runs.
