I think that's just about anywhere under the Bureau Of Land Management or areas the feed the main rivers out west.

I don't know about being mandated to connect to the grid, but IF a system is grid-connected using what is termed "smart inverters" then they must shut down when the power goes out or they will feed back into the system and have the potential to electrocute linemen (who think the wires have been disconnected) -or supply power to storm-damaged, dangling wires.
