Why would you have a server (DC) that long powered off, it for sure will give delays and less response of the network. 
But you could turn it off as long as you want, once it powers up it will sync the AD again. 

So no, the controller is not removed from you domain. You need todo that manualy. 
I suggest you read: 

And not, dont forget if pc's/servers that have there DNS pointed to that server.
If so, adjust that also.
