Introduction: A model considering variation in demand and power production capacity has been developed for a system comprising one gas and one stream turbine. Concept of scheduled inspection at regular intervals of time for maintenance has also been introduced. Initially both the unit i.e. the gas turbine as well as the stream turbine are operating. On failure of the gas turbine, system goes to down state, whereas on failure of the stream turbine, the system may be kept in up state with only gas turbine working or put to down state according as the buyer of the power so generated is ready to pay higher amount or not. Computational work has been done for the cost benefit analysis and interesting numerical results have been obtained regarding various parameters involved which affect the economy of the system. Semi- Markov process and regenerative point technique have been used to analyze the system.
