Texas is expecting 21,000 MW of wind-generated electricity, and their transmission grid is only built to handle 18,500. To put that in context, a typical coal plant handles 600 MW.

The UK has also struggled with the challenge of surplus power, and energy surpluses in Chile—which have resulted in straight-up free power—are starting to have negative effects on the energy industry. It's not the worst problem to have, but it's still a problem.
