Methods and systems for the generation of electrical energy through the combination of steam flows produced from different fuel sources. Steam produced from processing of a biomass fuel source is combined with steam produced from the processing of natural gas or fossil fuel and routed through a steam turbine generator to produce electrical energy. The steam is preferably reheated after partial processing in the steam turbine generator and then recirculated for further processing in the steam turbine generators. Following extraction of all available energy from the steam, the steam is condensed to water, the feedwater is then reheated and pumped to the boilers of both energy sources for conversion into steam.
