Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity or more efficiency which results in a net increase of power generated. Repowering can happen in several different ways. It can be as small as switching out and replacing a boiler, to as large as replacing the entire system to create a more powerful system entirely.

Boilers are basically vessels used for heating the water and converting it to steam, as the name suggests. Boilers vessels generally use an internal heat source for boiling the water. Generally the steam is used as a utility in process plants and needs to be available at certain temperature and pressure conditions.

A Solar Receiver Steam Generator (SRSG) is a key component of a Concentrated Solar Power (CSP) generating plant. The SRSG, also known as a boiler or receiver, is a high-efficiency boiler positioned on top of a tower (typically 300 to 400 ft above grade), and surrounded by a field of mirrors (heliostats) that focus and concentrate sunlight onto the receiver tubes.

• Facility's heat-to-power ratio: If the heat-to-power ratio in the facility is higher than that for the cogeneration plant, the excess steam demand is usually met by utility boilers. Any saving in steam demand (by better heat recovery) saves fuel in the utility boilers and leaves the operation of the cogeneration plant unchanged.
