Granted, it's summer time which is peak power generation time in most places, especially during the day when things heat up and more folks have AC, fans, lights, computers, TVs, etc... running. But, power companies do turn the power generation up and down CONSTANTLY. And by constantly, I mean that they may adjust power every 15 minutes, 24 hours a day. I worked for a power company for a few years. It's pretty amazing how they monitor the weather, news, etc... and turn the knob up and down on the plants all day long. There are even plants called "peaker" plants which sit idle, not running until days when the load on the grid goes way up (and consequently the price of electricity) and then they turn them on and kick everything into high gear. So it's possible to have plants (wind, gas, whatever) sitting and not doing anything at times.
