The performance of operating repowering projects is reviewed. A combined cycle is created by replacing some or all of the steam generation capacity in an existing power plant with a waste heat boiler linked to a gas turbine. The benefits are: station heat rate can be reduced, relatively low-cost, short-lead-time capacity can be added, no additional cooling water is required, an existing site can be used, the life of a generating unit with an old, but serviceable, steam turbine can be greatly extended. Data are compiled for 19 power stations repowered and results show that some of the installations performed successfully, others did not. But, repowering is a very acceptable concept because reduction in heat rate of an oil-fired steam station is of value and modern gas turbines are more efficient than their predecessors. (MCW)
