That was actually my thought! I wanted to start the first utility company in the game: Boundless Power Inc. The limiting factor is the length of spark link. From the generator any one spark link branch can only have 100 connected spark links (unless that’s been changed. I haven’t tested it in awhile).
It’s fully possible to share spark across plots with different owners. The only thing I’d like to see is a way to charge coin for spark and raising the spark link limit.
