In fact, in 1979, the prohibition on the use of natural gas under the FUA even led Westinghouse to rename the product to "combustion turbines", and the Gas Turbine Systems Division (GTSD) was renamed Combustion Turbine Systems "Division" (CTSD). It was as if removing the word "gas" from the product name would change its stature under the law. (It may be that EPRI, the Electric Power Research Institute, may have had something to do with this change in name as well.)
