Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity

Nameplate capacity

Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity or maximum effect, refers to the intended technical full–load sustained output of a facility such as a power plant, a chemical plant, fuel plant, metal refinery, mine, and many others.For dispatchable power,...

 or more efficiency

Capacity factor

The net capacity factor or load factor of a power plant is the ratio of the actual output of a power plant over a period of time and its potential output if it had operated at full nameplate capacity the entire time...

 which results in a net increase of power generated.
