How much time elapsed between one save to another?
In my area there are a lot of electricity power interruption, so I don't know how much I can count on OneNote autosaving.

You can set at which intervals the notebooks are backed up, if that helps surviving the power interrupts.
It won't matter. ON saves your changes to a local cache every few milliseconds, and then sends changes from the cache to the notebook on the server every few minutes. If that process is interrupted, ON will notice the server notebook does not have the changes in the cache and will re-sync when you start OneNote again.
