To reinforce this, I was reading an article (can't remember the source now, unfortunately) about Caesar's switching to solar power and having to pay the Nevada utility ~$90 million dollars to offset the "lost revenue" to the utility.
Caesar's wasn't obligated to pay, but they chose to to prevent the utility from passing that cost on to the residential customers.
Found some sources. Closer to $50 million than $90 million, and these imply that Caesar's didn't have as much of a choice in it as in the source I first read (but can't find).
