GECOL already has two 9FA gas turbines from GE that are running with Mark VIe controls. The engineering work for the plant’s GT13E1 gas turbines started in 2017, but there were some initial delays due to political events and COVID-19. Once the project was under way, GE’s engineering team put the Mark VIe controls to the test to make sure they were going to run smoothly for GECOL, including extensive simulator tests in Baden Automation Laboratories. Throughout the project, there was very close communication and cooperation between the controls engineering and commissioning teams. The first unit (GT 14) was commissioned in Q2 of 2021. The second unit (GT12) was installed and commissioned in Q1 2022, and the remaining units (GT11 and GT13) are expected to be in operation by Q4 2023.
