AP4 Group Services
Established in 2009, by John Downing and Chris Rychcik, Turbine Controls & Excitation Group (TC&E) was created to fill a void in the controls, exciter, and LCI field engineering services sector for large gas and steam turbines. TC&E has since grown from a small services company focused on troubleshooting and outage support, to performing complex control system upgrades.
In 2018, in partnership with TMEIC, TC&E introduced the first non-OEM LCI digital front end (DFE) upgrade in the industry.
In 2019, in conjunction with Basler, TC&E introduced the first non-OEM digital front end retrofit for an EX2000 excitation system, the DECS-2100.
As the TC&E brand and reputation continued to grow, TC&E was acquired by AP+M Holdings LLC, at the end of 2020, to form AP4 Group. TC&E continues to build its brand, under the AP Group, and expand its abilities by working with other well known equipment providers throughout the power generation space.
