Literally the entire State has to walk on eggshells power wise during the summer in order to avoid a cascading failure or having controlled blackouts in order to prevent a cascading failure. And they're proposing to add even more power demanding appliances to that grid. I'm sorry but this is a poorly thought out plan of action. Maybe if they built a couple more nuclear plants they could manage but wind and solar farms aren't going to cut it.

Edit: all of this on top of the fact that our climate is getting hotter year after year so even more power is going to be necessary for air conditioning in more and more areas within the state even those that don't see such hot Summers previously will start to put a strain on the grid trying to keep cool in the summer. All of this on top of the likely dwindling supply of power from the Hoover dam due to the receding Colorado River, also due to climate change BTW.
