Ed. Note: At the same 1994 ASME Gas Turbine Conference where the above-referenced ASME paper by Scalzo, et al. was presented, Westinghouse also delivered a paper announcing plans to develop a 250 MW-class gas turbine, the 501G. To be designed by the Westinghouse/MHI/FiatAvio alliance, (MHI, a long-time licensee, had also collaborated with and funded Westinghouse in the development of the 501F) the design featured a steam-cooled transition duct, another of many industry firsts for Westinghouse (see Appendix I). The first 501G was installed at Lakeland Electric's McIntosh station and was first synchronized to the grid in April, 1999.
