It depends on the region, but most of the US doesn't have too much of a problem. There is always pushback from locals (understandable), but there has been billions in transmission built in the Oklahoma, Kansas, Nebraska, and West Texas regions to name a few areas. A lot of this is to help with the existing (ageing) infrastructure as well as helping make sure the ~22GW of currently built wind capacity can actually serve load and not be curtailed 24/7. In fact, a lot of that wind wouldn't have been built without the necessary transmission. Keep in mind that there is greater than a ~2:1 return on investment from these projects (difference in production cost in a year with the projects there and then not there) if I recall correctly. The Western Interconnect of the US seems to favor using RAS and phase-shifting transformers in order to avoid as many transmission projects. A Remedial Action Scheme is basically an automated system that keeps certain catastrophic events from happening when a certain triggering event happens. Phase shifting transformers can help push back on certain interregional flows. I think this makes more sense in the Western Interconnect as it isn't as much of a dense network as the Eastern Interconnect. You have dense load centers in Denver, California, and Oregon/Washington with a dessert and mountain range in the middle (forms a donut). It is very rural over the vast majority of the distance, so I imagine transmission is pretty expensive and harder to justify. They do have interregional planning groups in the West though.
