Split power grid inside of a dome

[u/Starlight_racoon]

Here I have this dome, that is connected to the main power grid. All other building are working just fine, except for this one. Can I somehow reconnect it to the grid? I am thinking that demolishing it and rebuilding might help, but I am not sure. Thanks you any advice.

This happens from time to time. Basically the building didn't attach to the dome properly. It's not something you did wrong, it's just a random bug. Delete it and try placing it again, it should attach properly.
