Engineer's rig somehow providing power again (2-10)

Ross

I believe the answer is:

'providing power again' is the definition.

'engineer's rig somehow' is the wordplay.
'somehow' is an anagram indicator.
'engineers'+'rig'='engineersrig'
'engineersrig' with letters rearranged gives 'RE-ENERGISING'.

I've seen this clue in The Guardian.
