The research suggests a solution of the actual problem of analyzing the instability of generation of renewable sources of energy (RSE), in particular, solar power plants (SPP). The impact of instable RSE generation on the power balance in a local electric system is shown. The law of distribution of solar power plant’s generation for a certain time interval of the day during a year is analyzed. A mathematical model of SPP generation is proposed in the form of Gaussian mixtures. The basic characteristics of probabilistic nature of solar plant’s generation are obtained. The possibility to coordinate solar plant’s generation with daily consumption graphs is assessed. The probability of covering the given loadgraph by SEP generation during acertain time interval of the day throughout the year is determined. The obtained probabilistic characteristics of the balancing process make it possible to determine the 
probability of ensuring the balance reliabilityby SPP generation in a set interval of the day.
