Is anyone else having power issues with their buildings?

I have plenty of power on all my planets to cover everything built, but various buildings on each planet suddenly starting showing a lighting symbol flashing over them and im getting a message 'xxx building is not connected to a energy source.'

This started happening a few days ago, am i missing something and/or is there a way to fix the issue?

Thank you

You need to place your buildings in such a way that they are covered by your power plants' coverage. If there's not enough space around power plants, use Energy Supply Towers to extend the coverage.

That did the trick, i never noticed the power buildings had ranges before. Thank you very much for the helpfull tip. Honer to you! =^.^=
