…they are quite predictable actually.
This is how it worked when we first got here: the power went out around 10:00AM in most of the house and stayed off all day. In the whole house. Then it came on partially in the evening, not sure what time. I had light in my bathroom but not the bedroom. There were no lights in the bathroom down the hallway or downstairs. Then at around 9:00 or 10:00PM all the lights would go out for a minute and then the generator kicked on and we had light in the entire house again, all night long. Then the generator went off again around 10:00 AM and the whole thing started again.
At least, that is how it worked when the rest of the team was here. Now, with only the tree of us, they turn the generator off all the time. I just had to ask for the second morning in a row if they would turn it on so we could see in our bathroom, charge our electronics and use the internet. The other issue is that they turn the generator off on us at night. The three of us are all total night owls and it seems like when our security detail gets tired of listening to us talk at night, the generator goes off. We grumble about it for about an hour and then, resigned to our fates, go off to bed.
