What is happening with electricity in Tennessee
Every new power plant, battery or big customer has to join a waiting list before it can plug into the grid. This is what that list looks like in Tennessee right now.
Where every request ever filed here ended up
Most requests in the US are withdrawn — a developer tests a site and moves on. That is normal, not a warning sign for Tennessee.
