Coincidentally, in the case of the aforementioned regulations a STAG (STeam And Gas) cycle qualification is/was to provide about 6% of its steam generation to process. At this operating condition, the overall performance approaches that of a conventional STAG power generation cycle. Later in this paper, tables are provided that define GE’s gas turbine and gas engine product characteristics, which in turn illustrate the wide application range and flexibility of these products to support cogeneration applications. For purposes of the following discussions, “thermally optimized” cogeneration systems are defined as those developed using non- condensing steam turbine generators or condensing units operated at minimum flow to the condenser for cooling purposes
