Fusion is still a lab experiment.

If a fusion reactor with an energy gain of 100 and stable operation in the 10_000_000 second range were announced tomorrow, we would be only 20 years away from breaking sod on the first commercial-scale plant -- if the process goes very smoothly.

From there it would be only 30 to 50 years before fusion was making a significant contribution on a global scale, if it can compete commercially.
