'power station feature' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.

'stylish in welsh peninsula limiting temperature' is the wordplay.
'stylish' becomes 'cool'.
'welsh peninsula' becomes 'gower' (I've seen this before).
'limiting' indicates putting letters inside.
'temperature' becomes 't' (abbreviation).
'gower' going around 't' is 'gtower'.
'cool'+'in'+'gtower'='COOLING-TOWER'
