The main objective of this paper is to evaluate the thermodynamic potential of a complex hybrid power plant based on a gas turbine, integrated with an electrolyser powered by: a wind farm, a biomass gasification unit and a methanation reactor. The system serves as an electricity accumulator. The calculation methodology and the basic assumptions for the analysis are presented. The calculations provided the basic thermodynamic parameters of the streams in all the major points of the system. A gas turbine was selected and key thermodynamic indicators of the system operation were determined. The annual products were calculated and the influence of the size of electrolyser on the share of electricity supply from the wind farm was presented.
