Possibility of night called for this in power cut? (11)
I believe the answer is:
candlelight
'power cut?' is the definition.
The answer and definition can be both types of natural phenomena as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'possibility of night called for this' is the wordplay.
'night called' anagrams to 'CANDLELIGHT'.
Though, I'm not clear how this is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for candlelight that I've seen before include "Dim illumination from tapers, etc" , "Early illumination" , "Romantic glow" .)
