Authorities push for utility increase (5,5)

'utility increase' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'authorities push' is the wordplay.
I cannot really see how this works, but
'authorities' could be 'powers' (I've seen this in another clue) and 'powers' is located in the answer.
'push' could be 'urge' (I've seen this in another clue) and 'urge' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...

'for' is the link.

Can you help me to learn more?
