TGPS has conducted combined cycle performance tests of over 100 power plants around the world. We have executed the combined cycle performance test for projects around world.
Our company has experience in combined cycles with equipment of different suppliers such as GE, Siemens, Alstom, Mitsubishi, Ansaldo among others.
The plant configuration can be 1X1, 2X1, 3X1, multi-shaft and single-shaft units.. We have arranged testing for 1, 2 or even 3-phase projects, where the final combined cycle plant was not installed at the same time: first the simple cycle, then the steam turbine and finally BOP and export steam elements.
Our team is ready to provide the most technically accurate power plant performance evaluation and to manage the combined cycle performance test execution so that you, and all stakeholders, are confident the test results will be 100% accurate.
Compliance with the applicable international performance test codes such as:

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.
Acceptance Test vs Diagnostic Test
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.
Overall Plant Assessment
In a combined cycle power plant, it is critical to look to the overall plant performance and analyzing the individual equipment without leaving aside the overall picture.
