In the US, this will never happen due to NIMBY zoning laws.

Most rural areas have pretty permissive zoning.

But also, other than Texas, I don't hear about a lot of regional over production. There's pretty good interconnection within and between the two major grids.

One reason you don't see overproduction is it's hard to get connected to grids. Local self-generation eliminates that roadblock. I think we're going to see increasing energy autarky in rural regions as solar gets cheaper.
