The paper refers to the calculations of the availability of the CHP unit fed on biogas. In the paper the authors present the results of exploitation investigations of two small biogas CHP units working in the waste-water treatment plant in Rzeszów. Investigation period is from January 2002 to December 2003. On the basis of these results the availability of biogas CHP units has been calculated. The results have been compared with the values of availability of small cogeneration systems based on a combustion engine or gas turbine fed on the non-renewable energy source - natural gas. The histograms of disconnections time of biogas CHP units have been presented. The function of occurrence of a specified disconnections time has been obtained as a lognormal function.
