Boldly addresses power charges (7)

I believe the answer is:

accosts

I'm a little stuck... Click here to teach me more about this clue!

'boldly addresses' is the definition.
'accosts' can be an answer for 'addresses' ('accost' can be a synonym of 'address'). I am unsure of the 'boldly' bit.

'power charges' is the wordplay.
'power' becomes 'AC' (AC is an example).
'charges' becomes 'costs' (I've seen this before).
'ac'+'costs'='ACCOSTS'

Can you help me to learn more?

(Other definitions for accosts that I've seen before include "As a solicitor does" , "Approaches boldly, solicits" , "Grabs" .)

I've seen this clue in the Sydney Morning Herald.
