How many power plants are needed in Fallout Shelter?
The number of power plants you need in Fallout Shelter really depends on the size of your vault and how many dwellers you've got. A good rule of thumb is to start with one power plant and expand as your population grows. Always keep an eye on your power gauge; if you see it dipping often, it's time to build another one. But remember, more power plants mean more dwellers need to work there, so balance is key!

Just build enough to keep the lights on, lol. Seriously though, add more whenever your power bar starts getting low too often. Better to have too much power than not enough.
Honestly, just one to start with. I've run a vault with 50+ dwellers with only a couple of power plants. It's all about efficient resource management and not overextending your energy needs.
One or two should be enough in the beginning. But as your Vault grows, you'll definitely need more. Don't overdo it at the start though!
