Since 2009, TGM has also provided detailed generator testing and analysis, and field repair on generators and exciters. TGM is turnkey and project-management based, focused on units operated by independent power producers, cogenerators, and other power producers that require the shortest outage durations to support availability requirements.
We have set ourselves apart from OEMs and other contractors with "The TGM Way"—bringing together the right people, the right plan, the right processes, the right tools, and the right attitude—for the total success of your project and the confidence that the outage will be completed to your specific requirements.


Turbine Generator Maintenance, Inc.®, TGM, was founded in 1986 by Anthony Collins as a steam turbine and generator maintenance company. After fifteen years of success, one of our good customers asked if we would consider working on combustion turbines and generators. In 2009, a generator service division was added to support electrical inspections, testing, and field repair of turbo generators from 300 MVA and below.
For more than a quarter of a century, TGM has been performing turnkey inspections and repairs on steam turbines, gas turbines, generators, and associated equipment for the majority of segments within the utility and heavy industrial markets.
As CEO, David Branton's goal is to develop TGM into a premier turbine generator service company that is known as process driven in everything that it does. The cornerstone of TGM is people, and our processes define the qualifications and the positions of each person.
