Gas turbine repowering has been a part of the power industry since the early 1980s. In some of the industrialized nations, many electric generating plants are now over 30 years old. These plants are still functioning, but they are among the last to be dispatched, since efficiency is low and cost of per kilowatt of electricity is high. Many of these plants are direct-fired facilities which are candidates for some form of repowering; i.e., replacement of the heat source (boiler) with a gas turbine and HRSG, or installation of a gas turbine/HRSG as an additional heat source. Repowering can also be applied to nuclear facilities, with a series of gas turbines replacing the reactor. This has been less common so far than repowering of direct-fired plants, but may become more common in the next century, as nuclear plants reach retirement age. This paper discusses briefly the types of repowering, and repowering advantages. 1 fig.
