Gas Turbines

Gas Turbines

TGPS has conducted several dozens of gas turbine performance test around the world. Our thermal performance engineers have conducted gas turbine performance tests of different OEMs such as GE, Alstom, Pratt & Whitney, Ansaldo, Siemens, Rolls Royce and Mitsubishi, among others.

Our performance testing company strictly follows the ASME PTC 22, ISO and DIN test protocols.

The gas turbine performance tests have involved different models of gas turbines, from 30 year old frame 5 units to the latest H-Class gas turbines. Our team of engineers is ready to work in project around the world and bring the instrumentation required to conduct an accurate and reliable test.

In addition to the evaluation overall gas turbine performance, TGPS evaluates in detail other parameters during a gas turbine performance test, such as gas turbine compressor efficiency, gas turbine combustion temperature and gas turbine efficiency.

Performance Test Procedure

For a combined cycle performance test, there are certain specific items to place special attention in the combined cycle performance test procedure.

  • Combined Cycle Isolation (thermal and electrical isolation)
  • Test Boundaries Definition
  • Combined Cycle Performance Guarantees
  • Testing Instrumentation
  • Calculation of final Combined Cycle Performance

TGPS has a diverse range of experience, not only in the CC configuration, but also in complex evaluation of projects that occurs in a multi-stage testing program as defined in the ASME PTC 46.


Depending on the objective of testing certain parameters are more critical than others. Only an experience power plant performance engineer can guide the process through the most efficient path to achieve the specific objectives. For a contractual performance test topics such as test uncertainty, performance guarantees are more relevant. In a diagnostic test, not only these parameters are important, but also looking to historical trends, power plant upgrades, operation modes, load cycling, among others. Our team uses the latest tools to diagnostic the combined cycle performance in an accurate and practical way. Results that can impact directly the combined cycle efficiency.

Why is Power Plant Efficiency Important?

Power Plant Efficiency is directly correlated to the business sustainability in terms of financial performance and long-term feasibility.
