We used to have power cuts lasting 3 or 4 days. I found a solution to that: I bought a 5.5Kw generator - miraculously we've not had a long power cut (longer than an hour) since 
We did have two separate days of planned maintenance power cuts this year when my daughter and son-in-law were staying (waiting for work to be completed on their house) and both needing to work from home, so the genny has been used.
