Abstract: “Age has an effect on the working and efficiency of generators in a Hydro Power plant. While we discuss about refurbishment of a Hydro Power Plant, we can plan to refurbish, uprate and modernization of generators. Stator and rotor are the main component which can be refurbished and upgraded in order to increase efficiency. In the case of “Bassi” Hydro Power Plant, we planned to refurbish the all four generators. In this paper we are focusing on rewinding of rotor and results thereof. While planning of refurbishment of a Hydro Power Plant, it can be discussed that generators can be refurbished completely or partly depending upon the condition of the generators. Among these two options time constraint and loss in power production are also taken into consideration. In the case of “Bassi Power Plant” there are four generators. Power plant cannot be stopped for refurbishment so it is decided to refurbish these generators one by one. Again a major issue to decide is whether go for complete re”
