The steam generated by the boilers operated a 250 kW turbogenerator. Engineer Charles Algernon Parsons demonstrated a DC steam-powered turbogenerator using a dynamo in 1887. It consists of two gas turbines by General Electric combined with one steam turbogenerator. Bertha worked on the turbogenerator for the Niagara Falls project. On 1 May 1932, the first stage of the turbogenerator plant was commissioned. The turbogenerator is long and its total weight is .
