Abstract
The operation and maintenance costs of six gas turbine plants in Western Europe, has been investigated. The reason is that here is a need for this knowledge when future new power plants are to be built in Norden with the gas turbine as the main component. It is also valuable to know the performance of such plants. Therefore information about labour force, overhauls, shut down routines and reached and expected environment values have been investigated. The report is based on personal interviews and written information about each plants. Of the six plants half of them were old plants and the other half has ordinary gas turbines with waste heat boilers. Two of the plants are operated in condensing mode and the remaining four have cogeneration applications. The distribution among the industry and the public sector is fifty-fifty. The investigation includes gas turbines in the sizes of 9-130 MWe. The combination of information shows a relation of the operation and maintenance costs (O and M) to the size of the turbine - large gas turbines give a lower O and M. Both calculated per kWhe and in percent of the investment costs. The operation conditions of the plant also influence the

Both calculated per kWhe and in percent of the investment costs. The operation conditions of the plant also influence the O and M of the turbine. Plants with long annual operation periods as well as plants with few start-ups have lower O and M costs per kWhe. Plants with shorter total operation periods (equalling to new plants) have lower operation and maintenance costs than units with a long total operation period. The reliability is high, from 98 to 100 %, whereas the availability varies between 90 and 98%. The availability does not seem to depend on the plant being industrial or public - combined cycle or an ordinary gas turbine with a waste heat boiler. (CLS).}
