What is TSE power plant lifetime extension?
What is TSE power plant lifetime extension?
Green energy sources such as photovoltaic plants and wind farms are increasingly feeding energy into our power grids. Since the energy from renewable energy sources is not generated at constant rates, conventional power plants are required to step in and fill the gaps.
The result is the need for high flexibility and shorter cycles between running at peak and minimum loads. This can have a dramatic impact on the power plant lifetime. Especially thick-walled pressure components are exposed to higher temperature transients, which result in fatigue that needs to be monitored.
TSE software is a computer program developed by TÜV SÜD that helps monitor the components with high precision and efficiency. It enables rapid, in-depth and realistic determination of a component’s state of repair against standards and regulations.
This helps power plant operators minimise downtime and execute predictive maintenance services. It identifies opportunities to improve flexibility, provides information on defects for condition-based maintenance, and determines appropriate inspection intervals.
Why TSE power plant lifetime extension is important
Why TSE power plant lifetime extension is important
Operators of conventional power plants face the challenge of competing in a highly competitive market, influenced by different energy technologies, legal requirements and governmental subventions. To operate a plant with the highest possible efficiency and effectiveness, operators need to minimise downtime while increasing flexibility and availability.
This can only be achieved if fatigue of components is monitored and predicted early to carry out predictive maintenance works. Operators require a solution that enables determination of the creep/fatigue condition with the measured values of subsequently installed sensors.
TÜV SÜD’s TSE software provides this solution for plant lifetime assessment and extension. In addition, it enables operators to re-determine the test dates of recurring tests based on the results of an exact creep/fatigue analysis.

As an experienced provider of third-party testing and inspection services, TÜV SÜD offers comprehensive support tailored to your individual needs.
Our testing and certification services ensure that all components fulfil the standards and regulations relevant for power-station operation.
Beyond this, our TSE software enables us to perform the required fatigue monitoring even more efficiently than before.
You save time and money while benefiting from significantly increased safety levels and life span of your power plant.
What our TSE power plant lifetime extension service includes
What our TSE power plant lifetime extension service includes
- Calculation of total fatigue, comprising creep fatigue and cyclic fatigue
- Calculation of fatigue in a single calculation step, even for very long periods
- Evaluation of available stress history (pressure and temperature curves)
- Method in conformity with the relevant standards and regulations, e.g. TRD 301/303 and EN 12952-3
- Mapping the scope of possible approaches under the standards and regulations (from conservative to maximally realistic)
- Efficient algorithm combined with high accuracy
The infographic below illustrates how TSE software can accurately assess the state of exhaustion of your power plant. The software can achieve this even if no previous data or measurements are available.
