In the first year TEServices was able to obtain a long term contract with Tennessee Valley Authority (now in second extension). Additionally, TEServices enlarged their customer base from 5 end-users in the first year to more than 60 by 2012.
Older and matured gas turbines are still supported, however, over the years TEServices has specialized in F-technology IGT?s such as GE F6FA, F7FA and F9FA, MHI and SW 501F and 701F, Siemens V84.3A and V94.3A and even aero-derivate PWPS GG8. This was done in part because of work performed for GTUsers, Europe, and EPRI, such as creating fuel nozzles and other components repair guidelines, verification of F-technology repairs, and new part manufacturing, brazing technology overview, F-technology workshops, component assessments, and extension programs. TEServices? facility in La Porte, Texas, contains a metallurgical laboratory specializing in superalloys, performing incoming evaluations, repair and coating qualifications, life assessments before and after repairs, and failure analyses. Since 2011, TEServices sacrificed more than 60 F-technology bucket/blades annually in order to perform metallurgical evaluations and mechanical testing (stress rupture, TMF and LCF) in new, As-Run and as repaired condition to extend their life for TEServices? customers (see ASME paper: GT2012-68363, Extending useful life of F-class gas turbine components).
