Imagine life without electricity in the contemporary world. We would be angry, frustrated and bored. We could not access our landline phones, television or radio. We could not cook and keeping things cold could be a serious problem. Those of us lucky enough to own electric cars could not charge them.
This is the problem that arises in your next story. This does not take place in the past when rugged individuals knew nothing about the joys of electricity.
Set up your scene and introduce your character in an interesting way. Then the power goes out and stays off not just for hours, but days. Think of the passage of time and how the character feels as each minute, each day passes with no change.
Describe the emotional state of your character as well as what the individual does to survive. Think about the senses. Smells. Sights. Taste. Touch.
Have fun with this one.
