Can I save my application halfway through and come back if the electricity goes out?

The system typically uses an "Explicit Save" function, not an automatic one. You must click the "Save" button (often at the bottom of the section) to ensure your data is stored. Crucial Rule: Always click SAVE after completing a section, especially before starting a major upload or if the power/internet is unstable. If you lose power without saving, you will lose the most recent unsaved changes.
