Distributed Generation (DG) is a global trend and it is actively spreading in Russia. In contrast to Western countries, the main incentive for the spread of DG in Russia is the desire of industrial owners to reduce the final cost of electricity. DG in Russia can successfully meet the challenge of supplying electricity to isolated and inaccessible areas and replacing outdated and inefficient generation. The widespread use of DG, including those based on renewable energy sources (RES) makes it necessary to create promising models for the inclusion of DG in the Unified Energy System (UES) of Russia. The paper deals with the efficiency of DG, analyses the application of this technology in Russia formulates the prospects for the development of DG in Russia and gives recommendations for the integration of DG.
