The paper deals with analysis of data about distribution network device failures and electric power supply outages from distribution companies. There are also suggestions how to improve reliability using new materials. Since each company has different structure of data monitoring the uniform methodology was created to enable comparison of processed results. Data structure, the way of distribution network device reliability evaluation and some of the preliminary results of the analyses are presented in this paper. There are also described the basic principles of the Reliability Centered Maintenance-RCM and its application to electric distribution network devices. Its aim is more effective maintenance program of equipment. The inputs of such analyses are databases of outages, maintenance, equipment condition and financial flow. The last part of the paper consists of introduction of fuel cell systems reliability in context of the grid-linked operation.
