How will that happen? China is building more generation as we speak. And I mean a lot. The gap is widening and the rate of change is even worse, thanks to "clean beautiful coal" or whatever Trump said.
You are aware that China is building dozens of new coal power plants right? Just this year they have commissioned 50.[1] Granted, it's less than before, but still much more than other developed countries.

Yeah, absolutely no way to bring down power prices when compared to China. They installed over 400 GW (peak) of new renewable capacity in 2025 and show no signs of intending to stop.
But still, it's possible that a smaller, dirtier build-out in the US will significantly drop prices relative to today, and certainly relative to the rest of the world (which is failing spectacularly at building out power infrastructure).
But yes, the only way you're ever going to smelt Aluminum in the US again is if you have customers who can't/won't buy Chinese Aluminum. And even then, worth keeping an eye on the richer Arabs states. They're quickly roofing over their deserts, and certainly don't worry about local NIMBY opposition to power lines...
