This patent describes a cogeneration system including at least a first and a second turbogenerator unit, each supplied through throttle valve means with steam at a higher throttle pressure for generating steam through extraction valve means at a lower extraction pressure and for exhausting steam to an associated condenser at a still lower exhaust pressure and under condenser constraints, while generating electrical power at an operating speed of the associated turbogenerator unit. The generated steam and electrical power are supplied to a plant together with electrical power derived from a tie-line, each of the turbogenerator units having a throttle flow input and a condenser flow output, at least one of the turbogenerator units having an extraction flow output, while generating output electrical power.
