The really critical cost isn't monetary but time. There's plenty of places where the interconnect queue is holding up projects a lot: https://www.forbes.com/sites/davidblackmon/2025/05/06/study-...

Whereas connecting generation to a substation near demand usually shows up as "negative demand" and doesn't require big upgrades.
