 The development of renewable energy sources, particularly wind generation, has led to changes in the structure of the energy mix in Poland. While onshore wind farms have been significantly curbed by new legislation, onshore wind farms are expected to play a larger role in future development. The paper provides a comprehensive analysis of the Polish wind sector from an electric power generation perspective, focusing on the production of electric power from wind and its correlation with demand for power in the Polish power system, PPS. The results indicate high variability in wind generation throughout the month or year, with the largest generation occurring during the night valley and greater wind generation in winter months. The lack of correlation between offshore wind power generation and real power demand in the PPS can be mitigated by the use of electricity storage systems.
