Why does hot weather cause power outages?

In:

Air conditioning.

A/C uses lots of power – as anyone who lives in a hot climate can tell you. Collectively that sometimes means that more power is needed than power plants can produce. If demand exceeds supply… someone stops getting power.

One of the other main issues is the generators create a lot of heat and that causes wearing down or malfunctioning of smaller parts. In extreme heat this is exacerbated by the ambient heat that just adds to how hot the generators or turbines are running.
